Dog care below freezing − how to keep your pet warm and safe from cold weather, road salt and more this winter

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/erik-christian-olstad-1505284">Erik Christian Olstad</a>, <a href="https://theconversation.com/institutions/university-of-california-davis-1312">University of California, Davis</a> Time outside with your dog in the spring, summer and fall can be lovely. Visiting your favorite downtown café on a cool spring morning, going to a favorite dog park on a clear summer evening or going on walks along a river when the leaves are changing color are all wonderful when the weather is favorable. But in much of the country, when winter rolls around, previously hospitable conditions can <a href="https://theconversation.com/is-winter-miserable-for-wildlife-108734">quickly turn chilly and dangerous</a> for people and pups alike. Winter brings some unique challenges for dog owners, since dogs still need activity and socialization during colder seasons. Studies have shown that dog owners are almost 50% less likely to walk their dogs <a href="https://doi.org/10.3390/ani11113302">when the weather gets cold</a>. Knowing the basics of winter safety is critical to maintaining a healthy lifestyle for your dog. I am an <a href="https://www.vetmed.ucdavis.edu/faculty/erik-olstad">assistant professor</a> at the University of California Davis School of Veterinary Medicine who weathered polar vortexes with my dog while living in Michigan early in my career. While I’ve since moved to sunny California, I’ve seen how quickly frigid temperatures can turn dangerous for pets. <h2>Breed and age differences</h2> Not all dogs have the same abilities to deal with cold weather. A short-coated dog like a Chihuahua is much more susceptible to the dangers of cold weather than a thick-coated husky. When the weather dips below 40 degrees Fahrenheit (4 degrees Celsius), the well-acclimated husky may be comfortable, whereas the Chihuahua would shiver and be at risk of hypothermia. Additionally, if your dog is used to warm weather, but you decide to move to a colder region, the dog will need time to acclimate to that colder weather, even if they have a thick coat. Age also affects cold-weather resilience. Puppies and elderly dogs can’t withstand the chill as well as other dogs, but every dog is unique – each may have individual health conditions or physical attributes that make them more or less resilient to cold weather. <h2>When is my dog too cold?</h2> Pet owners should be able to recognize the symptoms of a dog that is getting too cold. Dogs will shiver, and some may vocalize or whine. Dogs may resist putting their feet down on the cold ground, or burrow, or try to find warmth in their environment when they are uncomfortable. Just like people, <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">dogs can get frostbite</a>. And just like people, the signs can take days to appear, making it hard to assess them in the moment. The most common sites for frostbite in dogs are their ears and the tips of their tails. Some of the initial signs of frostbite are skin discoloring, turning paler than normal, or purple, gray or even black; red, blistered skin; swelling; pain at the site; <a href="https://www.britannica.com/science/ulcer">or ulceration</a>. Other <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">serious signs of hypothermia</a> include sluggishness or lethargy, and if you observe them, please visit your veterinarian immediately. A good rule to live by is if it is too cold for you, it is too cold for your dog. Getting your dog a <a href="https://www.cnn.com/cnn-underscored/pets/best-winter-dog-coats-jackets">sweater or jacket</a> and <a href="https://www.akc.org/expert-advice/vets-corner/protect-dogs-paws-snow-ice-salt/">paw covers</a> can provide them with protection from the elements and keep them comfortable. Veterinarians also recommend closely monitoring your dog and limiting their time outside when the temperature nears the freezing point or drops below it. <h2>Road salt dangers</h2> Road salt that treats ice on streets and sidewalks <a href="https://www.cbc.ca/news/canada/kitchener-waterloo/ice-salt-toxic-for-pets-1.5020088">can also harm dogs</a>. When dogs walk on the salt, the sharp, rough edges of the salt crystals can irritate the sensitive skin on their paws. Dogs will often lick their feet when they’re dirty, wet or irritated, and if they ingest any salt doing that, they may face GI upset, dehydration, kidney failure, seizures or even death. Even small amounts of pure salt can <a href="https://www.petpoisonhelpline.com/pet-tips/my-dog-ate-road-salt-will-they-be-okay/">disrupt critical body functions</a> in dogs. Some companies make pet-safe salt, but in public it can be hard to tell what type of salt is on the ground. After walking your dog, wash off their feet or boots. You can also keep their paw fur trimmed to prevent snow from balling up or salt collecting in the fur. Applying a thin layer of petroleum jelly or <a href="https://www.akc.org/expert-advice/lifestyle/how-to-make-your-own-paw-balm-for-winter/">paw pad balm</a> to the skin of the paw pads can also help protect your pet’s paws from irritation. <h2>Antifreeze risks</h2> <a href="https://www.britannica.com/science/antifreeze-chemical-substance">Antifreeze, or ethylene glycol</a>, is in most vehicles to prevent the fluids from freezing when it gets cold out. Some people pour antifreeze into their toilets when away from their home to prevent the water in the toilet from freezing. Antifreeze is an exceptionally dangerous chemical to dogs and cats, as it tastes sweet but can be deadly when ingested. If a pet ingests even a small amount of antifreeze, the substance causes a chemical cascade in their body that results in severe kidney damage. If left untreated, the pet may have <a href="https://www.petpoisonhelpline.com/pet-owner-blog/antifreeze-poisoning/">permanent kidney damage or die</a>. There are safer antifreeze options on the market that use ingredients other than ethylene glycol. If your dog ingests antifreeze, please see your veterinarian immediately for treatment. When temperatures dip below freezing, the best thing pet owners can do is keep the time spent outside as minimal as possible. Try some <a href="https://www.akc.org/expert-advice/lifestyle/great-indoor-games-to-play-with-your-dog/">indoor activities</a>, like hide-and-seek with low-calorie treats, fetch or even an interactive obstacle course. Food puzzles can also keep your dog mentally engaged during indoor time. Although winter presents some unique challenges, it can still be an enjoyable and healthy time for you and your canine companion.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221709/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/erik-christian-olstad-1505284">Erik Christian Olstad</a>, Health Sciences Assistant Professor of Clinical Veterinary Medicine, <a href="https://theconversation.com/institutions/university-of-california-davis-1312">University of California, Davis</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Awful new details emerge after man's fatal fall from hot air balloon

Warning: Disturbing details New details have emerged of the moments before a man tragically fell to his death from a <a href="https://www.oversixty.com.au/news/news/man-dies-after-falling-from-hot-air-balloon-over-melbourne" target="_blank" rel="noopener">hot air balloon</a>. The man was one of ten people onboard the hot air balloon ride, which took off at around 7am on Monday. A video obtained by 7News, shows the man, dressed in a brown jumper, taking in the view over the city alongside other guests. Witnesses have also reported that the man looked fine and was even chatting with the ride operator about politics as the balloon launched into the air. As the ride reached around 450metres, just ten minutes later, with no warning whatsoever he shockingly exited the basket in what was reported to be an act of self-harm and plunged to his death. The pilot immediately made a distressed may day call as horrified passengers and motorists witnessed him fall through the air. Passengers onboard another hot air balloon, which was launched at the same time, recalled hearing the distress calls over the radio approximately 15 minutes into their ride. Not long after emergency services arrived at the horrifying scene in Albert Street, Preston in the city's north-east, where his body was found in a front yard. One witness recalled the incident and told the Today show: "My brother heard like a loud bang, almost like something like a large item falling in your house. And it wasn’t until we heard all the sirens that we came out." Passengers onboard the hot air balloon have been offered counselling by the operator, with officers currently preparing a report for the coroner. Images: 7News/ Daily Mail

Man dies after falling from hot air balloon over Melbourne

An unidentified man lost his life early on Monday morning after falling from a hot-air balloon above Preston, Melbourne. The incident, which occurred around 7:30 am on Albert Road, has left the neighbourhood in disbelief. Paramedics swiftly responded to the scene following distress calls, only to find the lifeless body of the man on the street. According to authorities, the victim was riding in the hot air balloon when the tragic accident unfolded. The area quickly became a hive of activity, with dozens of police officers cordoning off the road in both directions. Eyewitnesses reported a scene of chaos, with power lines falling onto the road and emergency service crews rushing to the aid of the victim. One neighbour, speaking to reporters from the Today show, recounted the harrowing moments leading up to the discovery of the man's body. "My brother heard like a loud bang, almost like something like a large item falling in your house. And it wasn’t until we heard all the sirens that we came out," he said. Expressions of condolences and solidarity have poured in from the local community and beyond, as news of the tragedy spreads. More updates are expected as authorities work to unravel the events leading up to this heartbreaking incident. Images: The Today Show | ABC News

"Cruel" shopper slammed for leaving dog in hot car

A woman has been slammed on social media for allegedly leaving her dog in an unattended car for 40 minutes on a hot day. The incident occurred at Warringah Mall in Sydney's north on Monday, when temperatures reached up to 28 degrees. Claire, claimed the dog-owner pulled up next to her in an undercover car park, and then watched the woman leave her pet locked in an unattended car while she shopped. "Myself and my mother waited till she got back," she told Yahoo News Australia. "It was around 3.15pm and she didn’t come back till just before 4pm". During that time, Claire said she called security, who attempted to contact the owner via a mobile number on the dog's harness. She also tried calling the RSPCA and police but claimed that not much could be done. When the owner finally returned, Claire questioned her about leaving the "panting and drooling" animal unattended, but the woman reportedly just "laughed and scoffed" before "driving away as quick as possible". Claire shared photos of the pup on Facebook and criticised the owner, for her "absolute irresponsibility and disgusting behaviour", calling her an "absolute d**khead". "People like you should not own animals," she wrote. While many agreed that the woman's actions were "absolutely awful," a few others argued the act was fine as the car was undercover and "the dog doesn't look hot and distressed at all." Another person who claimed to know the owner, said that the woman's car "has an aircon function which allows the air-conditioning to run when the engine is not running" and the pet is generally "very spoiled and happy". A few others disagreed, and said that the act was "cruel" and "simply disgusting" regardless. "Undercover or not you don't lock a baby in a car, you don't lock an animal in a car ... no excuse," one wrote. An RSPCA spokesperson has also spoken out and said that leaving a dog inside a car unattended is "always dangerous" no matter the location or the temperature outside. They said that even on mild days, temperatures in a car can "rapidly heat up" and can reach "double" the outside temperature. "When it’s 22 degrees Celsius outside, the inside of a car can reach a stifling 47 degrees and this is no environment for a dog," the spokesperson said. Image: Facebook

Yes, it’s getting more humid in summer. Here’s why

<a href="https://theconversation.com/profiles/steven-sherwood-272">Steven Sherwood</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Has Sydney felt more like Cairns lately? You’re not imagining it – millions of Australians up and down the east coast have sweltered through exceptionally high humidity in recent weeks. It’s due to normal weather patterns combined with a boost from global warming. Right now, the temperature of the sea surface is <a href="http://www.bom.gov.au/products/IDYOC052.Aus.SSTAnomaly.shtml">1–3°C above normal</a> for this time of year up and down the east coast. It’s particularly hot around the Queensland-New South Wales border and Tasmania’s east coast. When we have high ocean temperatures, we get more water evaporating. This is taken up by the air, which can hold more moisture when the air is hotter. This moist air is then carried to us by winds, and the sweating begins. <h2>Where does humidity come from?</h2> Humidity is just gaseous water held in the air after evaporating from liquid water or ice. It is called a vapour because it condenses into rain — the more humid, the more likely rain is. Higher humidity makes us feel hotter in warm weather, and slows the drying of laundry on a clothesline or of plants in the garden. How do we measure it? Two common ways are the “dew point” and “relative humidity”. At any given air temperature, there’s a limit to how much vapour the air will retain. Any vapour above this limit will just condense out. But the limit roughly doubles with every 10°C of warming; the dew point is the temperature where the vapour would hit the limit. The less vapour there is in the air, the colder the dew point. Relative humidity is the ratio of how much vapour the air has compared to the maximum it would retain. If you’re in Tasmania and see that relative humidity is at 100%, you might be confused. But this measure essentially tracks how “full” the air is. At 100% relative humidity, the dew point matches the actual temperature and no more vapour can be added. If the dew point is 10°C below the actual temperature, relative humidity is about 50%. How do we measure it? The dew point can be measured directly using a chilled mirror and a laser to detect condensation. More often it’s calculated from measurements of relative humidity and temperature. Relative humidity determines whether material exposed to the air will moisten or dry out. That’s why relative-humidity sensors use cheap water-absorbing materials (early ones used a strand of human hair!). <h2>What does a changing climate mean for humidity?</h2> The world’s higher ocean temperatures are unambiguously attributable to global warming, largely from the greenhouse gases we have added by burning fossil fuels. To date, more than 90% of all the extra heat thereby trapped has gone into the oceans. The amount of water vapour over the oceans has increased by roughly 5% since the industrial era began, in lockstep with global warming. Global warming will continue until we stop it. That means the atmosphere will keep getting more humid. If the world manages to keep global warming below 2°C, we should avoid the worst health outcomes from more humidity. But even then, we would expect up to another 5% increase in peak water vapour. Right now, we are seeing higher-than-normal temperatures in most of our surrounding oceans, with only a few exceptions. The areas hit hardest by rising humidity are mostly those that are already humid, like Queensland and the Northern Territory. Although peak dew points are rising, you may be confused to hear average relative humidity is actually <a href="https://www.pnas.org/doi/full/10.1073/pnas.1722312115">falling over land</a>. That’s because the land is warming so fast the average dew points aren’t quite keeping up with temperature, lowering the ratio. That means, alas, that Australia faces a double whammy: increasing water stress and bushfire risk as well as sweatier summers. <h2>Humidity can be very dangerous</h2> Our natural cooling system in hot weather is evaporation of sweat. Sweat forms on your skin, and the air evaporates it, taking the heat with it. But this only works to a point. When the dew point is higher, our self-cooling methods get less and less effective. How important this is depends on how hot you feel. On a moderate but muggy day, you might feel fine until you need to climb four flights of stairs and end up sweaty and exhausted. On a hotter but less muggy day you’d feel the heat at the outset, but would more easily handle the stairs. The Bureau of Meteorology uses something called “<a href="https://media.bom.gov.au/social/blog/1153/apparent-feels-like-temperature/">apparent temperature</a>” to capture the combined effect of temperature and humidity, although this assumes you’re not exerting yourself. How you feel with more exertion can be captured by other measures, such as the “wet bulb globe temperature” now being used at sporting events such as the Australian Open. The Bureau has recently begun providing <a href="http://www.bom.gov.au/places/nsw/sydney/forecast/detailed/">humidity and apparent temperature forecasts</a> as a beta product, which is great for activity planning. This type of information will become more important as the heat builds. As humidity increases during peak humid heat episodes, it makes heat stress worse and moves us toward our body’s physical limits. <a href="https://www.pnas.org/doi/10.1073/pnas.2316003120">Recent research</a> has shown the combination of humidity and heat could make parts of the planet unlivable if Paris Agreement targets are not met, beginning in India and spreading elsewhere in the tropics – including the Top End of Australia. We need to prepare now for increasing heat, while doing everything we can to stop the routine burning of fossil fuels as soon as possible to maintain a margin of safety for humanity.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221748/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/steven-sherwood-272">Steven Sherwood</a>, Professor of Atmospheric Sciences, Climate Change Research Centre, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Jimmy Barnes' granddaughter's touching tribute at Red Hot Summer

With Jimmy Barnes currently recovering from <a href="https://www.oversixty.com.au/health/caring/the-dose-of-magic-helping-jimmy-barnes-recover-after-surgery" target="_blank" rel="noopener">open heart surgery</a>, there was no way he could perform at the Red Hot Summer Tour, but his family and friends have come together to put on a show in honour of the star. The Barnes All-Stars, formed by none other than Jimmy's own daughter Mahalia, includes stars like Jon Stevens, Chris Cheney, and his legendary Cold Chisel bandmate, Ian Moss. The band have been headlining for the first three shows of the tour, and performed classic songs by Cold Chisel and Jimmy Barnes, which were compiled by the rock star himself. While the band put on a stellar show, Jimmy's granddaughter, Ruby Rogers' performance of the the Chisel classic Flame Trees, stole the hearts of fans. "In case you didn’t get to see this fantastic performance, this is granddaughter Ruby filling in for me on the weekend," Jimmy tweeted, gushing over her performance. "I love her so much. Thanks everyone. Full video on my FB page," he added. <blockquote class="twitter-tweet"> In case you didn’t get to see this fantastic performance, this is granddaughter Ruby filling in for me on the weekend.

What does El Niño do to the weather in your state?

<a href="https://theconversation.com/profiles/kimberley-reid-767059">Kimberley Reid</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> You’ve probably heard El Niño brings hot and dry weather to the eastern states, but what about the rest of Australia? Are we all in for a scorcher this summer? El Niño is what scientists call a <a href="https://www.climatechangeinaustralia.gov.au/en/overview/climate-system/australian-climate-influences/">climate driver</a>. But it’s just one of many. These climate drivers control year-to-year variations in the weather. Some years are hotter and drier, while others are cooler and wetter. Australia is particularly prone to weather whiplash because our continent is buffeted by climate drivers to our north, south, east and west. The dominant driver in your state may be one of the lesser-known influences. <figure><iframe src="https://www.youtube.com/embed/iVhi1wq2sTY?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Understanding Climate Drivers (Bureau of Meteorology)</figcaption></figure> <h2>East: El Niño Southern Oscillation</h2> The El Niño Southern Oscillation (ENSO) is the resident climate driver in the Pacific Ocean and the driver with the biggest influence over Australian weather. Differences in sea surface temperatures and winds across the Pacific determine whether we swing towards El Niño (the boy) or La Niña (the girl). <a href="http://www.bom.gov.au/climate/about/?bookmark=enso">During the El Niño phase</a>, sea surface temperatures near South America are warmer than normal and they are cooler than normal off the coast of eastern Australia. Additionally, trade winds that blow from east to west across the Pacific weaken. El Niño brings hotter daytime temperatures, but often <a href="http://www.bom.gov.au/climate/enso/#tabs=Pacific-Ocean&pacific=History">cooler nights</a>. That’s because reduced cloud cover allows more heat to escape into space overnight. So the same process that increases the chances of heatwaves can also raise the <a href="https://www.agric.wa.gov.au/climate-weather/historical-frost-and-heat-maps-south-west-land-division">risk of frost</a> in Western Australia, New South Wales, the Australian Capital Territory and Victoria. Australia as a whole is typically drier during an El Niño event. In the tropical regions, El Niño can delay the <a href="http://www.bom.gov.au/climate/updates/articles/a008-el-nino-and-australia.shtml">onset of the monsoon and reduce the likelihood of tropical cyclones</a>. In the southern states, the hot and dry conditions increase the chance of intense bushfires. La Niña is the opposite phase. Waters off eastern Australia are warmer than usual, increasing the <a href="http://www.bom.gov.au/climate/enso/#tabs=Pacific-Ocean&pacific=History&enso-impacts=La-Ni%C3%B1a-impacts">chance of tropical cyclones</a> and an earlier start to the monsoon for WA, the Northern Territory and Queensland. So what does El Niño do to the weather in your state? Hover over your state in the interactive map to find out. <iframe id="tc-infographic-1008" class="tc-infographic" style="border: none;" src="https://cdn.theconversation.com/infographics/1008/7f37ae91389db072906b320ffd54d0fefd840c0d/site/index.html" width="100%" height="400px" frameborder="0"></iframe> <h2>West: Indian Ocean Dipole</h2> The <a href="http://www.bom.gov.au/climate/about/?bookmark=iod">Indian Ocean Dipole</a> is like ENSO’s Indian Ocean cousin. A positive Indian Ocean Dipole is declared when ocean temperatures near Africa are warmer than normal and ocean temperatures off the coast of Sumatra are cooler than usual. A positive dipole tends to bring warmer and drier conditions, particularly to western and central Australia. A negative Indian Ocean Dipole is the reverse and is associated with wetter than normal weather and an increase in <a href="https://pursuit.unimelb.edu.au/articles/why-more-clouds-can-mean-less-rain-in-australia">northwest cloudbands</a>. <h2>North: Madden-Julian Oscillation</h2> The <a href="http://www.bom.gov.au/climate/about/?bookmark=mjo">Madden-Julian Oscillation</a> is a pulse of storms that start in the Indian Ocean, travel over Northern Australia and Indonesia and die in the Pacific Ocean. Ahead of the pulse, the air sinks, causing sunny and dry weather. Under the pulse is high storm activity and typically heavy rainfall. We describe the Madden-Julian Oscillation based on whether the pulse of storms is <a href="http://www.bom.gov.au/climate/mjo/">active or inactive</a> and where the storm activity is located on its path between the Indian and Pacific Oceans. As well as causing rainfall, the Madden-Julian Oscillation can control the timing of the monsoon onset and <a href="http://www.bom.gov.au/climate/about/?bookmark=tc">tropical cyclone formation</a>. <h2>South: Southern Annular Mode</h2> The <a href="http://www.bom.gov.au/climate/about/?bookmark=sam">Southern Annular Mode</a> controls the north and south position of the westerly winds that whizz around the globe in the Southern Ocean. When the winds are further north than usual, we call this the negative phase. But when the westerly wind move towards Antarctica, we call this the positive phase. The phase of the Southern Annular Mode <a href="https://rmets.onlinelibrary.wiley.com/doi/abs/10.1002/joc.1370">affects how many weather systems</a>, like cold fronts, make landfall over southern Australia. A positive mode may also draw tropical moist air south, which happened in 2022 during the extensive flooding over eastern Australia. <h2>Climate drivers control the odds, but not the result</h2> These four key climate drivers affect the weather on average (over months and seasons), but they do not dictate the exact day-to-day weather we experience. As the Gippsland region of Victoria <a href="https://www.theguardian.com/australia-news/2023/oct/05/victoria-floods-flooding-warnings-gippsland-region-flood-and-fires-evacuation">saw in October</a>, heavy rainfall can still occur during an El Niño. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=407&fit=crop&dpr=1 600w, https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=407&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=407&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=512&fit=crop&dpr=1 754w, https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=512&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=512&fit=crop&dpr=3 2262w" alt="Map of Australia showing the difference from normal rainfall during October 2023, with a large wet patch around Gippsland, Victoria." /></a><figcaption>Difference from normal rainfall during October 2023, showing defined wet area around Gippsland, Victoria surrounded by drier conditions.

They can select the best players and develop ingenious strategies, but that doesn’t guarantee a win every time. Players can get injured on the field or simply have a bad game. These uncontrollable factors are challenging to predict and may change the result from what we would expect. Scientists call this stochasticity. The climate drivers are the football coach, but the day-to-day weather systems are the players. The Bureau of Meteorology <a href="http://www.bom.gov.au/climate/enso/">releases an update</a> on all of these drivers every two weeks. The update explains which drivers are currently active and the forecast for the next few weeks. So, if you are wondering why the weather is cooler during summer, or it’s raining in the middle of the dry season, perhaps take a look at which driver is steering Australia’s weather at the moment.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/218257/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/kimberley-reid-767059">Kimberley Reid</a>, Postdoctoral Research Fellow in Atmospheric Sciences, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

It’s extremely hot and I’m feeling weak and dizzy. Could I have heat stroke?

<a href="https://theconversation.com/profiles/lily-hospers-1060107">Lily Hospers</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/james-smallcombe-1412548">James Smallcombe</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/ollie-jay-114164">Ollie Jay</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Australia is braced for a hot, dry summer. El Nino is back, and this year it will occur alongside an <a href="https://www.abc.net.au/news/2023-08-22/positive-indian-ocean-dipole-to-coincide-with-el-nino/102756378">Indian Ocean dipole</a>, a climate pattern which will further amplify this hot and dry effect. Hot weather can place great stress on our bodies. When the environmental conditions exceed the limit at which we can adequately cope, we can suffer from heat-related illnesses. Heat illnesses can vary, from relatively mild heat exhaustion to the potentially life-threatening condition of heat stroke. <h2>What are the signs and symptoms?</h2> If you’re suffering from heat exhaustion, you may feel weakness, nausea, headaches or dizziness. Mild <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/heat-related-illness.aspx">symptoms of heat exhaustion</a> can often be treated at home by reducing your levels of physical activity, finding shade, removing excess clothing, hydrating with water and perhaps even taking a cool shower. If left unchecked, heat exhaustion can progress to the far more serious condition of heat stroke, where your core temperature climbs upwards of 40°C. <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/heat-related-illness.aspx">Symptoms</a> can develop rapidly and may include confusion, disorientation, agitation, convulsions, or it could even result in a coma. Heat stroke is a medical emergency and requires urgent treatment. Call an ambulance and start rapid, aggressive cooling by immersing the person in cold water (such as a cold bath). If this isn’t possible, apply ice packs to their neck, armpits and groin and cover the skin with lots of cool water. When it comes to cooling someone with suspected heat stroke, the quicker the better: cool first, transport second. <h2>Why do we overheat?</h2> Environmental conditions play an important role in determining our heat stress risk. If the air temperature, humidity and levels of sun exposure are high, we are much more likely to dangerously overheat. When the body gets hot, the heart pumps more warm blood to our skin to help lose heat. As air temperature rises, this way of shedding heat becomes ineffective. When air temperature is higher than the temperature of the skin (normally around 35°C), we start gaining heat from our surroundings. Sweating is by far our most effective physiological means of keeping cool. However, it is the evaporation of sweat from our skin that provides cooling relief. When the air is humid, it already contains a lot of moisture, and this reduces how efficiently sweat evaporates. Our physical activity levels and clothing also impact heat stress risk. When we move, our bodies generate metabolic heat as a by-product. The more intense physical activity is, the more heat we must lose to avoid dangerous rises in core temperature. Finally, clothing can act as an insulator and barrier for the evaporation of sweat, making it even more difficult for us to keep cool. <h2>Who is most vulnerable in the heat?</h2> Some people <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/people-most-at-risk.aspx">are at greater risk</a> of developing heat illness than others. This can result from physiological limitations, such as a decreased capacity to sweat, or a reduced capacity to adapt our behaviour. When these two risk factors coincide, it’s a perfect storm of vulnerability. Take, for example, an elderly outdoor agricultural worker. Being aged over 60, their physiological capacity to sweat is reduced. The worker may also be wearing heavy safety clothing, which may further limit heat loss from the body. If they don’t slow down, seek shelter and adequately hydrate, they become even more vulnerable. When a person dies of heat stroke – which is relatively easy to diagnose – heat will be listed as a cause of death on a death certificate. Between 2001 and 2018 in Australia, 473 heat-related deaths were <a href="https://www.sciencedirect.com/science/article/pii/S2212420921006324">officially reported</a>. However, the true association between heat and death is thought to be far greater, with an <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(20)30100-5/fulltext">estimated 36,000 deaths</a> in Australia between 2006 and 2017. This is because most people who die during extreme heat events do not die from heat stroke. Instead, they they die of <a href="https://www.nejm.org/doi/full/10.1056/nejm199607113350203">other medical complications</a> such as cardiovascular or renal collapse, as additional strain is placed on essential organs such as the heart and kidneys. People with underlying health conditions are more likely to succumb to heat-associated complications before they develop critical core temperature (over 40°C) and heat stroke. In such cases, while the additional physiological strain imposed by the heat probably “caused” the death, the official “cause of death” is often listed as something else, such as a heart attack. This can make understanding the true health burden of extreme heat more difficult. <h2>How to stay safe in the heat</h2> Thankfully, there are effective, low-cost <a href="https://twitter.com/TheLancet/status/1677702906789740545">ways</a> of staying safe in the heat. These include: <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/215084/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <ul> <li>staying adequately hydrated</li> <li>getting out of the heat to a cooler area indoors or shaded area outdoors</li> <li>loosening or removing clothing</li> <li>cooling down any way you can: <ul> <li>using an electric fan (which can be used at 37°C and below, irrespective of age and humidity)</li> <li>using a cold-water spray</li> <li>applying a cool, damp sponge or cloth</li> <li>wetting clothes and skin</li> <li>having a cool shower or bath</li> <li>applying ice packs or crushed ice in a damp towel on the neck, groin and armpits.</li> </ul> </li> </ul> <a href="https://theconversation.com/profiles/lily-hospers-1060107">Lily Hospers</a>, PhD Candidate, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/james-smallcombe-1412548">James Smallcombe</a>, Post-doctoral Research Associate, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/ollie-jay-114164">Ollie Jay</a>, Professor of Heat & Health; Director of Heat & Health Research Incubator; Director of Thermal Ergonomics Laboratory, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

“Deeply disappointed”: The Wiggles hit out at council’s “harsh” use of iconic song

The Wiggles have taken aim at the Western Australian city of Bunbury for using their iconic song in a “harsh” way. The childrens’ entertainers found out the local council had been playing their song Hot Potato on an endless loop to deter homeless people from congregating. The song had been playing at the Graham Bricknell Music Shell, a stage in one of the town’s parks, that plays host to bands and events. When not in use for entertainment purposes, homeless people would gather under the shell and pitch tent to seek shelter from the elements. After being alerted to the fact that their song was being used in such a callous way, The Wiggles contacted The City of Bunbury and banned them from using the song. In a statement given to the <a href="https://thewest.com.au/entertainment/the-wiggles-slap-the-city-of-bunbury-with-music-ban-over-homelessness-row--c-12413889" target="_blank" rel="noopener">West Australian, </a>they said, “The Wiggles’ music is created to bring joy and happiness to children and families around the world, and we are deeply disappointed to hear that it is being used in any other way.” The council had been using the Wiggles’ song for around six months before the band issued their ban. Mayor of Bunbury Jaysen Miguel defended his decision to play the music, saying, “The City of Bunbury has been running music on and off there for the past six months, as happens across Australia and across the world where you can have music in certain areas to deter anti-social behaviours.” “But... there has been a known problem where people are getting in and turning the music up to full bore.” Local homeless cafe provider Intown Centre said the council needed a better response to the homelessness crisis, as Chair David Bailey said, “In the last couple of days, I have been walking around and I have heard it, but I did not think it was the council.” “I thought it was someone with a CD player,” he said. “It did strike me as odd. It is harsh . . . (and) there needs to be a better response.” Image credits: Getty Images

Extreme weather is landing more Australians in hospital – and heat is the biggest culprit

<a href="https://theconversation.com/profiles/amy-peden-1136424">Amy Peden</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Hospital admissions for injuries directly attributable to extreme weather events – such as heatwaves, bushfires and storms – have increased in Australia over the past decade. A new <a href="https://www.aihw.gov.au/reports/injury/extreme-weather-injuries/contents/about">report</a> from the Australian Institute of Health and Welfare (AIHW) shows 9,119 Australians were hospitalised for injuries from extreme weather from 2012-22 and 677 people died from these injuries in the decade up to 2021. In 2021-22, there were 754 injury hospitalisations directly related to extreme weather, compared to 576 in 2011-12. Extreme heat is responsible for most weather-related injuries. Exposure to prolonged natural heat can result in physical conditions ranging from mild heat stroke, to organ damage and <a href="https://www.dea.org.au/wp-content/uploads/2021/01/DEA-Fact-Sheet_HeatwavesWEB.pdf">death</a>. As Australia heads into summer with an El Niño, it’s important understand and prepare for the health risks associated with extreme weather. <h2>A spike every three years</h2> Extreme weather-related hospitalisations have spiked at more than 1,000 cases every three years, with the spikes becoming progressively higher. There were: <ul> <li>1,027 injury hospitalisations in 2013–14</li> <li>1,033 in 2016–17</li> <li>1,108 in 2019–20.</li> </ul> <iframe id="vLaas" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/vLaas/1/" width="100%" height="400px" frameborder="0"></iframe> In each of these three years, extreme heat had the biggest impact on hospital admissions and deaths. <iframe id="P03sm" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/P03sm/1/" width="100%" height="400px" frameborder="0"></iframe> Extreme heat accounted for 7,104 injury hospitalisations (78% of all injury hospitalisations) and 293 deaths (43% of all injury deaths) in the ten year period analysed. In 2011-12, there were 354 injury hospitalisations directly related to extreme heat. This rose to 579 by 2021-22. <h2>El Niño and La Niña</h2> Over the past three decades, extreme weather events have increased in <a href="https://www.ipcc.ch/report/ar5/syr/">frequency</a> and <a href="http://www.bom.gov.au/state-of-the-climate/">severity</a>. In Australia, El Niño drives a period of reduced rainfall, warmer temperatures and increased bushfire danger. La Niña, on the other hand, is associated with above average rainfall, cooler daytime temperatures and increased chance of tropical cyclones and flood events. Although similar numbers of heatwave-related hospitalisations occurred in El Niño and La Niña years studied, the number of injuries related to bushfires was higher in El Niño years. During the 2019–20 bushfires, in the week beginning January 5 2020, there were 1,100 more hospitalisations than the previous five-year average, an 11% increase. Although El Niño hasn’t directly been proved as the cause for these three spikes, according to the Bureau of Meteorology, two of the three years (2016-17 and 2019-20) were El Niño summers. And the other year (2013-14) was the warmest neutral year on record at that time. <h2>Regional differences</h2> Exposure to excessive natural heat was the most common cause leading to injury hospitalisation for all the mainland states and territories. From 2019 to 2022, there were 2,143 hospital admissions related to extreme heat, including: <ul> <li>717 patients from Queensland</li> <li>410 from Victoria</li> <li>348 from NSW</li> <li>267 from South Australia</li> <li>266 from Western Australia</li> <li>73 from the Northern Territory</li> <li>23 from the ACT</li> <li>19 from Tasmania.</li> </ul> <figure class="align-center "><img src="https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=632&fit=crop&dpr=1 600w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=632&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=632&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=794&fit=crop&dpr=1 754w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=794&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=794&fit=crop&dpr=3 2262w" alt="" /><figcaption><a class="source" href="https://www.aihw.gov.au/reports-data/latest-reports">AIHW National Hospital Morbidity Database</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> The report also includes state and territory data on hospitalisations related to extreme cold and storms. During the ten-year period analysed, there were 773 injury hospitalisations and 242 deaths related to extreme cold. Extreme rain or storms accounted for 348 injury hospitalisations and 77 deaths. From 2019 to 2022, there were 191 hospitalisations related to extreme cold, with Victoria recording the highest number (51, compared to 40 in next-placed NSW). During the same period there were 111 hospitalisations related to rain and storms, with 52 occurring in NSW and 28 in Queensland. <h2>What about for bushfires?</h2> Over the ten-year period studied, there were 894 hospitalisations and 65 deaths related to bushfires. Bushfire-related injury hospitalisations and deaths peaked in 2019–20, an El Niño year with 174 hospitalisations and 35 deaths. The two most common injuries that result from bushfires are smoke inhalation and burns. During the 2019–20 bushfires, in the week beginning 5 January 2020 there were 1,100 more respiratory hospitalisations than the previous five-year average, an 11% increase. The greatest increase in the hospitalisation rate for burns was 30% in the week beginning December 15 2019 — 0.8 per 100,000 persons (about 210 hospitalisations), compared with the previous 5-year average of 0.6 per 100,000 (an average of 155 hospitalisations). <h2>Some people are particularly vulnerable</h2> Anyone can be affected by extreme weather-related injuries but some population groups are more at risk than others. This includes older people, children, people with disabilities, those with pre-existing or chronic health conditions, outdoor workers, and those with greater <a href="https://www.mdpi.com/2071-1050/15/1/813">socioeconomic disadvantage</a>. People in these groups may have reduced capacity to avoid or reduce the health impacts of extreme weather conditions, for example older people taking medication may be less able to regulate their body temperature. “Thermal inequity” includes people living in poor quality housing who have difficulty accessing adequate heating and cooling. For heat-related injuries between 2019–20 and 2021–22, people aged 65 and over were the most commonly admitted to hospital, followed by people aged 25–44. Across age groups, men had higher numbers of heat related injury hospitalisations than women. This difference was most notable among those aged 25-44 and 45-64 years, where over twice as many men were hospitalised due to extreme heat as women. <h2>We still don’t have a full picture</h2> The AIHW data only includes injuries which were serious enough for patients to be admitted to hospital; it doesn’t include cases where patients treated in an emergency department and sent home without being admitted. It includes injuries that were directly attributable to weather-related events but does not include injuries that were indirectly related. For example, it doesn’t include injuries from road traffic accidents that occur due to wet weather, since the primary cause of injury would be recorded as “transport”. Improved surveillance of weather-related injuries could help the health system and the community better prepare for responding to extreme weather conditions. For example, better data aids communities in predicting what resources will be needed during periods of extreme weather. A more complete picture of injuries during weather events could also be used to inform people of actions they can take to protect their own health. Given a predicted hot summer, this could be a matter of life or death.

"It was beautiful": Rare rainbow cloud stuns small farming town

The locals of a small farming town in Western Australia have been delighted with the sighting of a rare rainbow cloud. The colourful weather phenomenon appeared above the town of Goomalling, about 130km northwest of Perth in Western Australia, on Tuesday morning. Jenni Shaw was at her family-owned business when she got a text from a friend instructing her to look up at the sky. "We all went out the front and had a look and there was some bright, rainbow-type clouds in the sky that we hadn't seen before," she told <a href="https://www.abc.net.au/news/2023-10-24/rainbow-cloud-iridescence-irisation-delights-wheatbelt-community/103016928" target="_blank" rel="noopener">ABC</a>. “It was beautiful,” she said. “But we were a bit like ‘why is that like that?

"Hot girl summer": Jackie O turns heads in swimsuit on enchanting getaway

Radio host Jackie 'O' Henderson has embarked on a "magical" vacation to Ningaloo Reef in Western Australia, accompanied by her close friend, Gemma O’Neill – leaving left her fans in awe with the beachside photos she shared online. The 48-year-old shared an image of herself and Gemma on the sandy shore, prompting her followers to declare that Jackie was fully embracing a "hot girl summer". "Deserted beaches, sunsets, super moons, no phones, and swimming with gentle whale sharks 💛 @gemmyjean, thank you for this incredible birthday gift," Jackie captioned the photos, some of which showed the duo swimming alongside these magnificent creatures. "Wow, that looks absolutely amazing 🙌," remarked Kylie Gillies. "It looks absolutely incredible! Adding it to my list ❤️❤️❤️," chimed in Michelle Bridges. "Your beautiful friendship with Gem is heartwarming. Hip, hip hooray, Jack! ❤️," gushed Melissa Hoyer. "Seems like you had a blast on your little getaway! Looks like so much fun," one user commented, while another exclaimed, "Absolutely stunning!" "That's the way to live 🙌," added a third. "Radiant beauties basking in the joy of life!" another fan noted. Several others complimented Jackie, calling her "gorgeous" and the experience "magical". This exciting adventure followed an amusing incident in which Jackie was caught with an embarrassing item in her luggage while en route to Western Australia. Before her departure, the producers of the Kyle and Jackie O show surreptitiously placed a large vibrator in her carry-on bag, ensuring it would be discovered by airport security by attaching it to a sizeable aerosol can. Jackie recounted the prank to her listeners on-air, stating, "That [phallic object] was in my suitcase, planted by our staff, so that when I went through security, it was uncovered. I could have died!" "They placed this [adult toy] in my bag, thinking it would be a funny joke," she continued. "[Airport security] showed me the X-ray and asked, 'What is this?' And I genuinely had no idea." Video footage of the prank was shared on the show's Instagram account, featuring Jackie with airport security as they inspected her bag. "I'm turning beet red! Stop it!

Lots of women try herbs like black cohosh for menopausal symptoms like hot flushes – but does it work?

<a href="https://theconversation.com/profiles/sasha-taylor-1461085">Sasha Taylor</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/susan-davis-10376">Susan Davis</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Menopause is the stage of life where the ovaries stop releasing eggs and menstrual periods cease. Most Australian women go through menopause between <a href="https://www.nature.com/articles/nrdp20154">45 and 55</a> years of age, with the average age being 51 years, although some women may be younger. Hot flushes and night sweats are <a href="https://www.nature.com/articles/nrendo.2017.180">typical symptoms</a> of menopause, with vaginal dryness, muscle and joint pains, mood changes and sleep disturbance also commonly reported. Up to <a href="https://pubmed.ncbi.nlm.nih.gov/25706184/">75% of women</a> experience menopausal symptoms, with nearly 30% severely affected. These symptoms can negatively impact day-to-day life and wellbeing. The main therapies available include menopausal hormone therapy (MHT) and non-hormonal prescription therapy. Some women will elect to try complementary and alternative medicines, such as herbal medicines and nutritional supplements. Black cohosh is one of them. <h2>What causes hot flushes</h2> The cause of hormonal hot flushes (also called hot flashes) still isn’t completely understood, but the decline in oestrogen at menopause appears to play a role in a process that involves the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3833827/">area of the brain that regulates temperature</a> (the hypothalamus). Factors linked to a greater likelihood of hot flushes include <a href="https://pubmed.ncbi.nlm.nih.gov/19675142/">being overweight or having obesity</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/25706184/">smoking</a>. MHT, previously known as hormone replacement therapy (HRT), usually includes oestrogen and is the <a href="https://pubmed.ncbi.nlm.nih.gov/26444994/">most effective treatment</a> for menopausal symptoms, such as hot flushes. But women may choose complementary and alternative medicines instead – either because they shouldn’t take hormone therapy, for example because they have breast cancer, or because of personal preference. Close <a href="https://pubmed.ncbi.nlm.nih.gov/26224187/">to 40%</a> of Australian women report using complementary and alternative medicines for menopausal symptoms, and up to 20% using them specifically to treat hot flushes and sweats. <h2>A long history</h2> Complementary and alternative medicines have a long history of use in many cultures. Today, their potential benefits for menopausal symptoms are promoted by the companies that make and sell them. The <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6419242/">complementary and alternative medicines</a> women often try for menopausal symptoms include phytoestrogens, wild yam, dong quai, ginseng and black cohosh. Black cohosh (plant name Cimicifuga racemosa) was <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6599854/">traditionally</a> used by Native Americans to treat a variety of health concerns such as sore throat, kidney trouble, musculoskeletal pain and menstrual problems. It is now a popular herbal choice for hot flushes and night sweats, as well as vaginal dryness and mood changes. There are <a href="https://pubmed.ncbi.nlm.nih.gov/37252752/">many theories</a> for how the active ingredients in black cohosh might work in the body, such as acting like oestrogen, or affecting chemical pathways in the brain. But despite extensive research, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6599854/">evidence to support these theories remains inconclusive</a>. It is also not clear whether black cohosh is effective for hot flushes. Results from individual studies are mixed, with <a href="https://pubmed.ncbi.nlm.nih.gov/17565936/">some</a> finding black cohosh improves hot flushes, while <a href="https://pubmed.ncbi.nlm.nih.gov/18257142/">others</a> have found it doesn’t. A 2012 <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6599854/">review</a> combined all the results from studies of menopausal women using black cohosh to that date and found overall there was no proof black cohosh reduces hot flushes more effectively than an inactive treatment (placebo). <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6599854/">This review</a> also revealed that many studies did not use rigorous research methods, so the findings are hard to interpret. A more recent <a href="https://pubmed.ncbi.nlm.nih.gov/33021111/">review</a> of clinical trials claimed black cohosh may ease menopausal symptoms, but the included studies were mostly small, less than six months long, and included women with mild symptoms. There is also no meaningful evidence black cohosh helps other symptoms of menopause, such as vaginal symptoms, sexual problems, or poor general wellbeing, or that it protects against bone loss. Evidence for how black cohosh is absorbed and metabolised by the body is also lacking, and it is not known what dose or formulation is best to use. More good quality studies are needed to decide whether black cohosh works for hot flushes and other menopausal symptoms. <h2>Is it safe to try?</h2> A <a href="https://pubmed.ncbi.nlm.nih.gov/33021111/">review of studies</a> suggests black cohosh is safe to use, although many of the studies have not reported possible adverse reactions in detail. Side effects such as gastrointestinal upset and rashes may occur. While there have been <a href="https://www.mja.com.au/journal/2008/188/7/liver-failure-associated-use-black-cohosh-menopausal-symptoms#0_i1091948">rare reports of liver damage</a>, there is <a href="https://pubmed.ncbi.nlm.nih.gov/21228727/">no clear evidence</a> black cohosh was the cause. Even so, in Australia, black cohosh manufacturers and suppliers are required to put a warning label for the potential of harm to the liver on their products. It is recommended black cohosh is not used by women with menopausal symptoms <a href="https://www.canceraustralia.gov.au/cancer-types/breast-cancer/impacted-by-breast-cancer/physical-changes/menopause/treatments-menopausal-symptoms">after breast cancer</a>, as its safety after breast cancer is uncertain. All women should consult with their doctor before using black cohosh if they are taking other medications in case of possible drug interactions. Many women like to try herbal therapies for hot flushes and other menopausal symptoms. While black cohosh is generally considered safe and some women may find it helps them, at the moment there is not enough scientific evidence to show its effects are any better than placebo. Women experiencing troublesome menopausal symptoms, such as hot flushes, should talk to their doctor about the best treatment options for them.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/211272/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/sasha-taylor-1461085">Sasha Taylor</a>, Research fellow, Chronic Disease & Ageing, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/susan-davis-10376">Susan Davis</a>, Chair of Women's Health, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

It’s warming up and mozzies are coming. Here’s how to mosquito-proof your backyard

<a href="https://theconversation.com/profiles/cameron-webb-6736">Cameron Webb</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> The weather is warming up and that means more time in the backyard. It also means more mosquitoes. Here are five ways you can mosquito-proof your backyard that <a href="https://theconversation.com/the-battle-against-bugs-its-time-to-end-chemical-warfare-111629">don’t rely on spraying insecticides</a>. <h2>1. Get rid of water</h2> Mosquitoes need water to complete their life cycles. They <a href="https://theconversation.com/feel-like-youre-a-mozzie-magnet-its-true-mosquitoes-prefer-to-bite-some-people-over-others-128788">need blood</a> – but water and warmth are just as important. Getting rid of water around your backyard will go a long way to keeping mosquitoes away. Water trapped in blocked roof gutters, drains and tarpaulin covering boats and trailers can be a great home for mosquitoes. Mosquitoes can exploit the tiniest of water sources too. It may just be the upturned lid of a discarded plastic drink bottle. If it traps water, mosquitoes will find it and lay eggs in it. Flush out your bird bath once a week to disrupt the mosquito’s life cycle. If you have a pond, installing a fountain will discourage mosquitoes. If you can’t keep water clean and circulating, consider filling it with sand and gravel to create an interesting garden bed for succulents or other plants. Mosquitoes will avoid clean and chlorinated swimming pools but will quickly move into “green pools”. If you’re not using your pool, consider <a href="https://www.krg.nsw.gov.au/Environment/Your-local-environment/Wildlife/Living-with-wildlife/Pool-to-pond/How-to-convert-your-pool">converting it to a “pond”</a> so that fish can help keep mosquito numbers down. <h2>2. Screen up – windows, doors and rainwater tanks</h2> If you can’t get rid of permanent water, at least stop mosquitoes getting to it (or you). Ensure <a href="https://www.brisbane.qld.gov.au/clean-and-green/natural-environment-and-water/water/water-smart-homes/rainwater-tanks/using-your-rainwater-tank">rainwater and septic tanks</a> have screens to stop mosquitoes entering. Screen windows and doors to stop mosquitoes entering the home. There are plenty of flexible screening options for windows, doors and balconies. If you live in a mosquito-prone area, creating a screened outdoor area (such as a pergola, courtyard, or balcony) will give you the opportunity to spend time outdoors without being hassled by mozzies. <h2>3. Choose your garden plants carefully</h2> Some plants <a href="https://bioone.org/journals/Journal-of-the-American-Mosquito-Control-Association/volume-25/issue-3/09-0016.1/Are-Commercially-Available-Essential-Oils-from-Australian-Native-Plants-Repellent/10.2987/09-0016.1.short">contain essential oils and other chemicals</a> that, when extracted and concentrated, provide protection against biting mosquitoes. But there isn’t a lot of evidence that the whole plant will keep mosquitoes away from your garden. Some types of plants are even marketed as “mozzie blockers” or “mosquito repelling”. But there isn’t <a href="https://www.veranda.com/outdoor-garden/a40592197/do-mosquito-repelling-plants-work/">any evidence of effectiveness</a>. In fact, some of these plants, <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1440-6055.2009.00736.x">such as melaleucas</a>, also happen to be associated with <a href="https://academic.oup.com/jme/article/36/4/515/903838">hot spots of mosquito breeding</a> in coastal Australia. The plants to avoid around the home are those that help mosquitoes breed, such as <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1440-6055.2008.00641.x">bromeliads</a>, which trap water. <h2>4. Encourage the animals that eat mosquitoes</h2> Mosquitoes are food for a range of animals including birds, bats, fish, frogs, lizards, insects, spiders and <a href="https://besjournals.onlinelibrary.wiley.com/doi/abs/10.1111/1365-2656.13965">dragonflies</a>. But don’t expect them to eat enough to keep all mosquitoes away. Bats are often promoted as a good “biological control” options but studies have shown mosquitoes are <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0077183">more likely to be a snack food</a> for small bats, not an irresistible staple of their diet. For garden ponds, frogs will eat a few adult mosquitoes but tadpoles of Australian frogs generally <a href="https://bioone.org/journals/journal-of-the-american-mosquito-control-association/volume-21/issue-4/8756-971X(2006)21%5b492%3aTOFCAF%5d2.0.CO%3b2/TADPOLES-OF-FOUR-COMMON-AUSTRALIAN-FROGS-ARE-NOT-EFFECTIVE-PREDATORS/10.2987/8756-971X(2006)21%5B492:TOFCAF%5D2.0.CO;2.short">don’t eat many mosquito “wrigglers”</a>. Australian native fish <a href="https://pubmed.ncbi.nlm.nih.gov/15532929/">will readily eat mosquitoes</a> and may be useful for backyard ponds. But not all fish are good. While “mosquitofish” (aka “plague minnow”) is distributed overseas to assist in mosquito control, <a href="https://meridian.allenpress.com/australian-zoologist/article/30/3/316/134508/Does-predation-by-the-fish-Gambusia-holbrooki">it’s a disaster for local wildlife</a> and, <a href="https://www.dpi.nsw.gov.au/fishing/aquatic-biosecurity/pests-diseases/freshwater-pests/finfish-species/gambusia">along with other exotic fish species</a>, should not be released into local waterways. <a href="https://link.springer.com/article/10.1007/s13157-019-01133-2">Healthier habitats promote fewer mosquitoes</a> so the best thing you can do is create habitats for the animals that eat mosquitoes. <h2>5. Avoid traps and other gadgets</h2> There are lots of devices purported to catch, kill, or repel mosquitoes from your garden. Some may catch a mosquito or two but they’re not very effective in knocking out big numbers. “Bug zappers” with bright lights will collect lots of flying insects. It’s just that mosquitoes make up a very small proportion of collections. Electrocuting devices, again, don’t seem to attract a lot of mosquitoes. Devices that <a href="https://theconversation.com/the-buzz-from-your-smartphone-wont-stop-mosquito-bites-92611">emit high frequency sounds</a> won’t help either. The best devices are typically those that are baited with carbon dioxide. These are a mainstay of state and territory <a href="https://www.health.nsw.gov.au/Infectious/mosquito-borne/Pages/surveillance.aspx">mosquito and arbovirus surveillance programs</a>. For a mosquito, the C0₂ tricks them into thinking the trap is a warm-blooded animal. The only problem is these can be expensive to run and don’t seem quite as effective for mosquito control <a href="https://bioone.org/journals/journal-of-the-american-mosquito-control-association/volume-22/issue-3/8756-971X(2006)22%5b490%3aTATTFA%5d2.0.CO%3b2/Traps-and-Trapping-Techniques-for-Adult-Mosquito-Control/10.2987/8756-971X(2006)22%5B490:TATTFA%5D2.0.CO;2.short">unless used in large numbers</a>. <h2>Yes, you’ll still need repellent</h2> Perhaps the best way to avoid mosquito bites is to pick an insect repellent <a href="https://www.phrp.com.au/issues/december-2016-volume-26-issue-5/a-review-of-recommendations-on-the-safe-and-effective-use-of-topical-mosquito-repellents/">recommended by health authorities</a> and <a href="https://theconversation.com/mozzies-biting-heres-how-to-choose-a-repellent-and-how-to-use-it-for-the-best-protection-150183">apply it</a> to ensure all exposed areas of skin are covered.

10 driving tips to stay safe in wet weather

Driving in the rain? Follow these tips for safe driving in wet weather This should go without saying, but reducing your speed – as long as you continue to keep with the flow of traffic, of course – is imperative when driving in the rain. After all, between the downpour and spray from other vehicles, heavy rain reduces visibility in all directions, and you need more time to react. Keep your distance Driving in the rain can be hazardous, and if ever there is an incident that requires you – or the driver in front you – to brake unexpectedly, you’ll want to have ample stopping distance on wet roads. Avoid heavy breaking While driving in the rain, you may find yourself in situations – whether you’re hydroplaning or finding yourself in a skid – that will tempt you to hit the brakes abruptly. Do your best to curb that impulse. Brakes can be affected greatly by water, losing a bit of their power when wet, which can be disastrous in an emergency. Easing off the brakes, slowing down and maintaining control of your vehicle is your best bet. Keep both hands on the wheel Control is of utmost importance when driving in the rain. After all, you need to be in command of your vehicle should an incident occur, and having both hands on the wheel while driving in the rain (no snacking or fiddling with the radio!) will ensure you can get out of a sticky situation quickly and efficiently. Keep windows from fogging up When driving in rain, windows tend to fog up as a result of the difference in temperatures inside and outside the car and can lead to decreased visibility. To stay safe and avoid accidents, simply press your car’s defrost button to clear-up the window. Turn on your A/C or roll down the windows by a couple of centimetres to remove the humidity from the vehicle and lower the temperature inside the car. If the issue persists, you may want to purchase a windshield cleaner and defogger. Beware of hydroplaning Hydroplaning happens when your car travels above the water without touching the ground. Given that a driver is left with little-to-no grip with the road and, thus, less control, this can be a dangerous set of circumstances. If you find yourself in such a situation, stay calm, ease off the brakes and do not turn your steering wheel; let your car slow down and the tires reattach to the road surface. Avoid puddles Windshield wipers should always be in working condition. Be vigilant about replacing them once per year, or whenever they start to leave streaks on the glass. Having wipers blades in tip-top shape ensures the best possible visibility when driving in the rain. Stay home if you can If you have no choice but to head outside during a heavy downpour, be sure to follow these driving tips. However, if you don’t have anywhere pressing to be, consider staying home and waiting it out until the storm subsides. Keep your headlights on With wet weather often comes fog and overall gloominess. With your surroundings slightly darkened, turning on your headlights ensures that you can see the road in front of you, and that other drivers can see you. Ensure windshield wipers are in working order Windshield wipers should always be in working condition. Be vigilant about replacing them once per year, or whenever they start to leave streaks on the glass. Having wipers blades in tip-top shape ensures the best possible visibility when driving in the rain.

How climate change will affect your pet – and how to help them cope

<a href="https://theconversation.com/profiles/edward-narayan-414899">Edward Narayan</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Earth has just experienced its <a href="https://www.theguardian.com/science/2023/jul/27/scientists-july-world-hottest-month-record-climate-temperatures">hottest month</a> since records began and Australia is now gearing up for an El Niño-fuelled summer. Extreme heat isn’t just challenging for humans – it brings suffering to our beloved pets, too. <a href="https://www.cabidigitallibrary.org/doi/10.1079/cabireviews.2023.0020">Research</a> I was involved in examined how climate change affects the welfare of animals, including pets. My colleagues and I used a concept for assessing animal welfare known as the “<a href="https://kb.rspca.org.au/knowledge-base/what-are-the-five-domains-and-how-do-they-differ-from-the-five-freedoms/">five-domains model</a>”. It’s a science-based structure for examining an animal’s: <ul> <li>nutrition</li> <li>environment</li> <li>physical health</li> <li>behaviour</li> <li>mental state.</li> </ul> The model evaluates the complete physiological and behavioural responses of animals to environmental stressors. While the effects of climate change on animals have been studied before, ours is the first study to apply the model to animal welfare specifically. We examined the academic literature and found climate change will harm animals across all five welfare domains. This applies to both wild and domesticated animals, including pets. So let’s take a look at how various types of pets will fare in a warming world – and how we can help them. <h2>Fish</h2> Fish are “ectotherms” – that is, they use external sources of heat to regulate their body temperature. So pet fish are vulnerable to changes in the water temperature of your home aquarium, which may occur during a heatwave. Extreme water temperatures can cause physical harm to fish. For example, it can increase a fish’s metabolic rate – meaning it <a href="https://e360.yale.edu/features/feeling-the-heat-warming-oceans-drive-fish-into-cooler-waters">needs more oxygen</a> to breathe . It can also <a href="https://www.nepjol.info/index.php/ON/article/view/4331">cause changes</a> such as slowed growth and reduced feeding. According to <a href="https://agriculture.vic.gov.au/livestock-and-animals/animal-welfare-victoria/other-pets/caring-for-your-pet-fish">official advice</a>, water in an indoor aquarium should generally be kept at between 20℃ and 25℃ (unless you are keeping tropical fish). Depending on your budget and aquarium size, you could opt to use a device to control the water temperature. Either way, it’s important to monitor the water temperature regularly. Also make sure the aquarium isn’t located near a window where it’s exposed to direct sunlight. Leaving your aquarium unattended for days or weeks in summer can be dangerous, due to the risk of heatwaves. If you’re going on a summer holiday, consider organising a <a href="https://www.thesprucepets.com/holiday-and-vacation-fish-care-and-feeding-1378525#:%7E:text=If%20you%20are%20going%20on,aquarium%20and%20can%20prove%20lethal">fish sitter</a> to check on the animal regularly. <h2>Birds</h2> Heat stress can change the <a href="https://www.vetexotic.theclinics.com/article/S1094-9194(16)00003-7/fulltext">physiology</a> of birds. For example, research into a wild population of small Australian robins showed during a heatwave, the birds <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/jav.02355">lost body mass</a> and abandoned their nests, and some died. Heat stress can also cause <a href="https://www.tandfonline.com/doi/abs/10.1207/s15327604jaws0101_5">abnormal behaviour in pet birds</a> such as <a href="https://www.tandfonline.com/doi/full/10.1080/1828051X.2016.1195711?src=recsys">feather picking</a>, when one bird repeatedly pecks at the feathers of another. In hot weather, regularly check your bird’s cage to make sure it’s clean and stocked with food and water. If the bird is in an outdoor cage or aviary, ensure it is shaded. And a shallow bird bath will help your feathered friend cool off. <h2>Dogs</h2> Dogs and cats can suffer on hot days. That’s especially true if they are: <ul> <li><a href="https://www.ejmanager.com/mnstemps/100/100-1626960667.pdf?t=1657722662">older or overweight</a></li> <li>have thick coats</li> <li>have short snouts/flat faces (which restricts air flow and makes it harder for them to cool down).</li> </ul> Heat stress can cause <a href="https://www.frontiersin.org/articles/10.3389/fvets.2021.742926/full?&utm_source=Email_to_ae_&utm_medium=Email&utm_content=T1_11.5e2_editor&utm_campaign=Email_publication&journalName=Frontiers_in_Veterinary_Science&id=742926">canine hyperthermia</a>, which means the dog’s body temperature becomes dangerously hot. Watch for <a href="https://www.rvc.ac.uk/small-animal-vet/teaching-and-research/fact-files/heatstroke-in-dogs-and-cats#:%7E:text=Early%20signs%20of%20heatstroke%20in%20pet%20animals&text=Panting%2C%20this%20can%20progress%20to,Red%20gums%20or%20tongue">early warning signs</a> of heat stress such as excessive panting and erratic movements. These symptoms can quickly escalate, leading to heat stroke and possible death. <a href="https://pubmed.ncbi.nlm.nih.gov/34828033/">More than 80%</a> of dog owners report exercising their dogs less vigorously, or for shorter periods, during hot weather. That can help avoid heat-related illness. But don’t reduce your dog’s activity levels too much, as that may lead to other health problems. Just time the walks to avoid the heat of the day. Refrain from leaving dogs unattended in vehicles, because they can easily overheat. In fact, it’s better to leave your dog inside home on a hot day, as long as they have a cool place to rest and plenty of water – perhaps even with ice cubes in it. And dogs love to cool off in a kiddie pool or under a sprinkler. If you take your dog out on a hot day, <a href="https://agriculture.vic.gov.au/livestock-and-animals/animal-welfare-victoria/dogs/health/heat-and-pets#:%7E:text=Be%20aware%20of%20the%20signs,not%20icy%20water%20and%20fanned">carry</a> a container of fresh, cool water for them. And don’t forget to slip-slop-slap: apply a sparing amount of pet sunscreen to your dogs’ exposed pink skin such as ear tips and nose. <h2>Cats</h2> Like other animals, cats can overheat in hot weather. Symptoms include panting heavily, drooling and a rapid pulse. Like with other animals, if you suspect your cat is suffering from heatstroke, call a vet immediately. Climate change and associated heat and floods is likely to aid the spread of parasites and illness <a href="https://www.forbes.com/sites/jeffmcmahon/2022/12/31/guess-whos-loving-climate-change-mosquitos-and-the-pathogens-they-carry/?sh=50654683174a">including</a> tick-borne diseases, <a href="https://pubs.er.usgs.gov/publication/70213352">flea</a> infestations and <a href="https://pubmed.ncbi.nlm.nih.gov/32145530/">heartworm</a>. This puts both cats and dogs at risk. In hot weather, the advice for cat owners is similar to that of dog owners: ensure your cat has plenty of shade and water, and put pet sunscreen on their ear tips and noses, especially if the cat is white. If possible, keep the cat inside during the hottest part of the day. Ensure at least one room is cool and ventilated. And in a heatwave, play with your cat either in the early morning or evening, when the temperature has cooled. <h2>A helping human hand</h2> While humans have the capacity to understand and prepare for climate change, pets will need our help to cope. This includes not just the pets listed above, but others too, including reptiles, guinea pigs and rabbits. As heatwaves and other extreme weather events become more common, the onus is on us to keep our pets safe.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/210724/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/edward-narayan-414899">Edward Narayan</a>, Senior Lecturer in Animal Science, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why is Australia having such a warm winter? A climate expert explains

<a href="https://theconversation.com/profiles/andrew-king-103126">Andrew King</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> If you’ve been out and about the past few days, you may have noticed Australia is experiencing an unseasonably warm winter. It’s been t-shirt weather across many parts of the country’s east, including Sydney where <a href="https://www.theguardian.com/environment/2023/jun/08/australia-ski-season-no-snow-skiing-snowboarding-resorts-closed-warm-weather">temperatures topped 25℃</a> on Sunday. Meanwhile, at high altitudes, the cover at some snowfields remains <a href="https://twitter.com/Cam_Walker/status/1685525535521402880">lacklustre</a>, even after warm conditions forced <a href="https://www.abc.net.au/news/2023-06-09/nsw-resorts-postpone-ski-snowboarding-kings-birthday-lack-snow/102456510">a delay</a> to the start of the traditional ski season. All this comes after the world experienced its hottest month since reliable records began. July brought <a href="https://qz.com/hottest-days-month-ever-recorded-july-2023-1850685494">an incredible 21 of the warmest 30 days</a> ever recorded – prompting the United Nations to declare a new era of “<a href="https://www.theguardian.com/science/2023/jul/27/scientists-july-world-hottest-month-record-climate-temperatures">global boiling</a>”. So what’s going on with the weather in Australia? Should we just enjoy the pleasant conditions, or is it a troubling sign of what’s to come under climate change? <h2>The nice weather, explained</h2> Australia’s unseasonably warm conditions are the result of both natural drivers of our weather and continued global warming. Since early July, warmer and drier conditions have dominated, due to a high pressure system sitting stubbornly over Australia at the moment. The clear conditions are leading to warmer daytime conditions. For example, daytime temperatures in Canberra in July – historically known for its cold winters – were <a href="https://www.9news.com.au/national/canberra-on-track-for-warmest-july-max-temps-on-record/1d0b9683-7dda-4cc0-b6a6-1e32bfa51407">the warmest on record</a>, despite frequent frosty mornings. Sydney has just experienced its <a href="https://www.theguardian.com/australia-news/2023/jul/31/australia-weather-august-warmth-heat-winds-tasmania#:%7E:text=Sydney%27s%2023.5C%20was%20enough,Hill%20goes%20back%20to%201858.">warmest July</a> on record, too. The high pressure has caused the air over the continent’s interior to warm. When cold fronts move across the south of Australia they push this warm air ahead of them, bringing warm and windy conditions to southern coastal areas. This is similar to the weather pattern we see in summer when cities such as Adelaide and Melbourne experience their hottest days. On Thursday, an approaching cold front is forecast to lift temperatures ahead of it to about 23℃ in Adelaide, 20℃ in Melbourne and 18℃ in Hobart. These are very warm temperatures in these locations for early August. And what about the oceans? Around Australia, oceans are a bit cooler than average in some places including <a href="http://www.bom.gov.au/products/IDYOC053.Global.SSTAnomaly.shtml">to the northwest of the continent</a>. But as the image below shows, ocean temperatures are currently above normal in many places around the world, including the west Indian Ocean and the central and eastern tropical Pacific. This indicates a developing El Niño and positive Indian Ocean Dipole – two natural climate drivers that affect Australia’s weather patterns. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=364&fit=crop&dpr=1 600w, https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=364&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=364&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=458&fit=crop&dpr=1 754w, https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=458&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=458&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Across most of the world’s oceans, temperatures remain well above normal. National Oceanic and Atmospheric Administration</figcaption></figure> This difference in ocean temperatures reduces the amount of atmospheric moisture over southern and eastern Australia. It also makes low pressure systems weaker and less frequent, reducing rainfall over the region. Over the coming months, warm and dry weather is expected to continue. For the rest of winter and spring, it’s expected to be <a href="http://www.bom.gov.au/climate/outlooks/#/rainfall/summary">drier than normal</a> in the southwest of Western Australia and much of the east of the continent. And the whole of Australia is predicted to be <a href="http://www.bom.gov.au/climate/outlooks/#/temperature/summary">warmer than normal</a> during this period. Of course, this doesn’t rule out occasional cool, wet spells. So is climate change a factor here? Yes. Australia’s land areas have <a href="https://www.ipcc.ch/report/ar6/wg1/downloads/factsheets/IPCC_AR6_WGI_Regional_Fact_Sheet_Australasia.pdf">already warmed by 1.4℃</a> since pre-industrial times. This is the result of humans burning fossil fuels and releasing greenhouse gases. The record winter warmth is part of a <a href="https://theconversation.com/australias-record-breaking-winter-warmth-linked-to-climate-change-83304">long-term upward trend</a> in Australian winter temperatures. As I’ve written <a href="https://theconversation.com/australias-record-breaking-winter-warmth-linked-to-climate-change-83304">previously</a>, there has been at least a 60-fold increase in the likelihood of a very warm winter that can be attributed to human-caused climate change. And we’re likely to see more record warm winters as the planet continues to warm. <h2>Looking north</h2> Of course, Australia’s spell of warm weather seems harmless compared to the Northern Hemisphere’s weird and wild summer. There, simultaneous extreme heatwaves have struck all four continents in recent weeks. Ocean temperatures are well <a href="https://www.washingtonpost.com/weather/2023/07/28/ocean-temperature-maps-heat-records/">above previous record highs</a> for this time of year. Last week, <a href="https://edition.cnn.com/2023/07/25/weather/canadian-wildfire-us-air-pollution/index.html">1,000 wildfires burned</a> in Canada alone. The planet’s warmest average temperatures typically happen in July. That’s because the Northern Hemisphere’s large land masses heat up more quickly than the oceans, in response to the high amounts of radiation from the sun. Still, the heat of the last few weeks has been unprecedented. The heatwaves are <a href="https://theconversation.com/a-climate-expert-explains-the-northern-hemispheres-weird-wild-summer-and-what-it-means-for-australia-209862">linked to</a> high-pressure weather systems that are “blocking” or deflecting oncoming low-pressure systems (and associated clouds and rain). On top of this, human-caused global warming is greatly increasing the chance of record-breaking extreme heat events and concurrent heatwaves across many regions. Worryingly, a <a href="https://www.worldweatherattribution.org/extreme-heat-in-north-america-europe-and-china-in-july-2023-made-much-more-likely-by-climate-change/">rapid analysis</a> by international experts suggests the extreme heat should not be viewed as unusual, given the effects of climate change. For example, it says China’s recent <a href="https://www.smh.com.au/world/asia/china-logs-52-2-celsius-as-extreme-weather-rewrites-records-20230718-p5dp1v.html">record-breaking heatwave</a> should now be expected about once in every five years, on average. Not all extreme weather events can be attributed to human-caused climate change. But the study found climate change significantly contributed to the recent heatwaves in China, North America and Europe. <h2>A sign of what’s to come</h2> The Northern Hemisphere’s heatwaves are very alarming. But Australia’s temperatures are also unusually high for winter – and this is also cause for concern. Warm winters in Australia can negatively affect some parts of the economy, including the ski industry. It also disrupts flora and fauna and increases the chance of “<a href="https://theconversation.com/flash-droughts-can-dry-out-soil-in-weeks-new-research-shows-what-they-look-like-in-australia-161286">flash droughts</a>” – where drier-than-normal conditions turn into severe drought in the space of weeks. The warm, dry conditions may also lead to an <a href="https://www.theguardian.com/cities/2018/aug/15/sydneys-bushfire-season-starts-in-winter-we-may-have-to-rethink-how-we-live">earlier start</a> to the fire season in Australia’s southeast. So while we may appreciate warm winter weather, we mustn’t forget what’s driving it – and how urgently we need to stabilise Earth’s climate by slashing greenhouse gas emissions.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/210693/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/andrew-king-103126">Andrew King</a>, Senior Lecturer in Climate Science, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"It's been a great privilege": Eddie McGuire delivers sad Millionaire Hot Seat news

Veteran host Eddie McGuire has announced that Millionaire Hot Seat will be taking a break at the end of January 2024. During a broadcast on 3AW, McGuire expressed both pride and sadness as he conveyed his gratitude to fans for their unwavering support over the years. McGuire revealed that a new show would be introduced in place of Millionaire Hot Seat at 5 o'clock on the Nine network after the 25th-anniversary milestone is reached in 2024. "It's with great pride and joy and also sadness that I announce this morning that Millionaire Hot Seat will go into hiatus at the end of January next year," McGuire announced. "We will finish off this year and there'll be a replacement show at five 'clock on the Nine network after we hit our 25th anniversary when we go into 2024. "I've had the privilege of being in everybody's lounge room for a long time every night at 5 o'clock and I love the fact that so many people come and say, 'I sit there with my grandparents and we did these things together'. It's been a great privilege." Reflecting on the show's impact, McGuire highlighted its multicultural appeal and the moments of personal significance shared by contestants. He recounted the touching story of a contestant who won $250,000 during the global financial crisis, and how the prize money was life-saving for him, preventing him from having to sell his house. Since its debut on April 20, 2009, Millionaire Hot Seat has become Australia's longest-running quiz show and the sole program in the country where contestants have the chance to win $1 million. Throughout its impressive 11-year run, the show has given away over $40 million and aired a remarkable 2500 episodes. Eddie McGuire's association with the show dates back to 1999 when he began hosting Who Wants To Be A Millionaire, which later evolved into the daily version known as Millionaire Hot Seat in 2009. The show has been a life-changing experience for many, with individuals like Edwin Daly and Antony McManus winning the top prize of $1 million. McManus, a retail worker from Melbourne, expressed how winning the show transformed his life, allowing him to purchase a beautiful apartment outright and secure a brighter future for himself and his husband. As the era of Millionaire Hot Seat comes to a temporary close, fans can look back on the show's incredible legacy and the profound impact it has had on countless lives. Eddie McGuire thanked everyone for their support, marking the end of an era while also anticipating the exciting new show that will take its place. Image: Nine Network

Extreme weather events are exactly the time to talk about climate change – here’s why

<a href="https://theconversation.com/profiles/josh-ettinger-1302389">Josh Ettinger</a>, <a href="https://theconversation.com/institutions/university-of-oxford-1260">University of Oxford</a> Record-breaking heatwaves are <a href="https://public.wmo.int/en/media/news/simultaneous-heatwaves-hit-northern-hemisphere-summer-of-extremes">sweeping across the northern hemisphere</a>, affecting large parts of southern Europe, the US and China. On July 24, Sicily recorded blistering temperatures <a href="https://www.bbc.com/news/world-europe-66302472">of more than 47.5℃</a> and wildfires are currently <a href="https://www.theguardian.com/world/2023/jul/25/how-bad-are-wildfires-in-greece-what-caused-them-visual-guide-heatwave">tearing through Greece</a>. The heatwaves come as <a href="https://www.reuters.com/graphics/CANADA-WILDFIRE/HISTORIC/znvnzebmavl/">record numbers of fires continue to burn</a> across Canada. A <a href="https://www.bbc.co.uk/news/science-environment-66289489">study by the World Weather Attribution group</a> found that these heatwaves would have been “virtually impossible” without climate change. In fact, the heatwave that is affecting parts of China was made 50 times more likely by global warming. This is exactly what climate scientists have been warning us about for decades – climate change makes many types of extreme weather event <a href="https://www.carbonbrief.org/explainer-what-the-new-ipcc-report-says-about-extreme-weather-and-climate-change/">more likely, more intense and longer lasting</a>. As a PhD researcher examining extreme weather events and climate change communication, I have spent the past four years exploring how extreme weather events may affect the way the public feels, thinks and acts on climate change. One area of interest to researchers is how extreme weather events might reduce the <a href="https://www.sciencedirect.com/science/article/pii/S0272494422000676">“psychological distance”</a> associated with climate change. While climate change can feel abstract and vague, extreme weather is something people can experience firsthand. But <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ab466a/meta">research offers contrasting results</a>. Some studies have found that extreme weather events lead to an <a href="https://www.journals.uchicago.edu/doi/full/10.1017/S0022381612000448?casa_token=dTns6Kvds1AAAAAA%3AkQcleVJ95vJUyh5Pg2vxvFEDbzfR1RsuOI131QCMO0wvdtIiLSVEq4EW6fZYwC7Yhraxj-NB9g">increased belief</a> that human-driven climate change is occurring and <a href="https://link.springer.com/article/10.1007/s10584-016-1837-4">greater support for climate action</a>. Others <a href="https://link.springer.com/article/10.1007/s10584-021-03176-z">find no effects</a> or suggest that these effects are <a href="https://www.sciencedirect.com/science/article/abs/pii/S0959378017309135?via%3Dihub">only temporary</a>. However, <a href="https://www.nature.com/articles/s41467-022-32412-y">we often underestimate</a> how much the public already cares about climate change. In Britain, <a href="https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1164127/desnz-pat-spring-2023-net-zero-and-climate-change.pdf">just 4% of the public</a> say they are not at all concerned about climate change, while only <a href="https://climatecommunication.yale.edu/about/projects/global-warmings-six-americas/">11% of Americans</a> dismiss the issue. Given that <a href="https://www.pewresearch.org/short-reads/2019/04/18/a-look-at-how-people-around-the-world-view-climate-change/">most people</a> are already concerned about climate change, an important question now is how to shift these existing concerns into action. <a href="https://theconversation.com/how-to-talk-to-your-family-and-friends-about-the-new-ipcc-report-five-tips-from-climate-change-communication-research-202306">Talking about climate change</a> is a powerful way of mobilising climate action, and extreme weather events provide helpful climate conversation starters. We can use these moments as opportunities to <a href="https://journals.sagepub.com/doi/10.1177/20563051231177930">engage our families, friends and communities</a> in discussions about how climate change may relate to these events and <a href="https://drawdown.org/solutions">what we can do about it</a>. So, if you decide to engage people you know in discussions about extreme weather and climate change, here are a few thoughts and guidelines to keep in mind. <h2>1. Listen and share perspectives</h2> <a href="https://www.sciencedirect.com/science/article/abs/pii/S0887618520300773">Extreme weather events can be traumatic</a> and climate change can evoke a wide range of emotional responses. If the person you are talking to is comfortable discussing the topic, ask them about their experiences and observations. Encourage them to tell stories and affirm the validity of their emotional response – whether they are afraid, angry, hopeful or worried. There is no one right way to feel about climate change, so listen to what they have to say and then share your own perspective too. <h2>2. Talk about planning and preparation</h2> When discussing extreme weather events, some people may link their experiences to climate change, while others focus on various local factors that contribute to extreme weather risks. The risks associated with extreme weather arise from a <a href="https://www.ipcc.ch/report/ar6/wg2/chapter/summary-for-policymakers/">combination</a> of factors. These include the weather itself, which can be influenced by climate change, the level of exposure of people and places to extreme weather and the vulnerability of those to harm. Climate change, for instance, can affect the frequency, intensity and duration of wildfires. But emergency responses, evacuation procedures, firefighting and healthcare systems are crucially important to reduce risks. There are also significant equity and justice implications of extreme weather as different populations are <a href="https://link.springer.com/article/10.1007/s41885-020-00060-5">affected disproportionally</a>. It’s also important to bear in mind that while climate change affects many extreme weather events, it <a href="https://www.carbonbrief.org/climate-change-not-the-main-driver-of-madagascar-food-crisis-scientists-find/">does not necessarily affect every instance</a>. Weather systems are complex and there are <a href="https://theconversation.com/heres-why-climate-change-isnt-always-to-blame-for-extreme-rainfall-206958">meteorological processes</a> that scientists are still trying to understand. We also need to make sure the roles of local planning and preparation in minimising the impact of these events are not overlooked. <h2>3. Challenge arguments about politicising the weather</h2> In May 2023, Republican governor of Florida, Ron DeSantis, dismissed concerns about global warming by claiming that he rejects the <a href="https://www.independent.co.uk/news/world/americas/us-politics/desantis-climate-change-fox-news-b2346211.html">“politicisation of the weather”</a>. Ontario premier, Doug Ford, recently <a href="https://www.cbc.ca/news/canada/toronto/ontario-climate-change-forest-fires-politics-ford-stiles-1.6869071">made a similar argument</a> about Canada’s wildfires. In conversations, it’s possible that someone might accuse you too of “politicising” the weather. You can (respectfully) push back against this claim. This argument is a <a href="https://www.cambridge.org/core/journals/global-sustainability/article/discourses-of-climate-delay/7B11B722E3E3454BB6212378E32985A7">discourse of climate delay</a>. Rather than denying the existence of human-driven climate change, climate delay discourses try to shut down climate discussions and cast doubt on the need to act very quickly. These arguments disingenuously assert that acting on climate is too expensive, too late or that someone else should take care of it – and they are <a href="https://theconversation.com/climate-change-multi-country-media-analysis-shows-scepticism-of-the-basic-science-is-dying-out-198303">becoming increasingly common</a>. If we shouldn’t discuss climate change when extreme weather occurs, then when is the right time? If we want to protect lives, we need to talk about – and act upon – the risks associated with extreme weather events and the disasters they can cause. If talking about climate change politicises the weather, so be it. The politics of climate denial and delay affected this summer’s weather, and our current decisions will shape our planet for thousands of years. The science is clear. Act now or face increasingly dire consequences.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/210412/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/josh-ettinger-1302389">Josh Ettinger</a>, Doctoral researcher, School of Geography and the Environment, <a href="https://theconversation.com/institutions/university-of-oxford-1260">University of Oxford</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

It’s official: Australia is set for a hot, dry El Niño. Here’s what that means for our flammable continent

<a href="https://theconversation.com/profiles/kevin-tolhurst-am-184">Kevin Tolhurst AM</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> An El Niño event has <a href="https://public.wmo.int/en/media/press-release/world-meteorological-organization-declares-onset-of-el-ni%C3%B1o-conditions">arrived</a>, according to the World Meteorological Organization, raising fears of record high global temperatures, extreme weather and, in Australia, a severe fire season. The El Niño is a reminder that bushfires are part of Australian life – especially as human-caused global warming worsens. But there are a few important considerations to note. First, <a href="http://www.bom.gov.au/climate/updates/articles/a008-el-nino-and-australia.shtml">not all</a> El Niño years result in bad bushfires. The presence of an El Niño is only one factor that determines the prevalence of bushfires. Other factors, such as the presence of drought, also come into play. And second, whether or not this fire season is a bad one, Australia must find a more sustainable and effective way to manage bushfires. The El Niño threat only makes the task more urgent. <h2>Understanding fire in Australia</h2> An El Niño is <a href="https://www.climate.gov/news-features/blogs/june-2023-enso-update-el-ni%C3%B1o-here">declared</a> when the sea surface temperature in large parts of the tropical Pacific Ocean warms significantly. The <a href="https://public.wmo.int/en/media/press-release/world-meteorological-organization-declares-onset-of-el-ni%C3%B1o-conditions">statement</a> by the World Meteorological Organization, released on Tuesday, said El Niño conditions have developed in the tropical Pacific for the first time in seven years “setting the stage for a likely surge in global temperatures and disruptive weather and climate patterns”. The organisation says there’s a 90% probability of the El Niño event continuing during the second half of 2023. It said El Niño can trigger extreme heat and also cause severe droughts over Australia and other parts of the world. But before we start planning ahead for the next bushfire season, it’s important to understand what drives bushfire risks – and the influence of climate change, fire management and events such as El Niño. The evidence for human-induced climate change is <a href="https://www.ipcc.ch/report/sixth-assessment-report-cycle/">irrefutable</a>. While the global climate has changed significantly <a href="https://theconversation.com/while-we-fixate-on-coronavirus-earth-is-hurtling-towards-a-catastrophe-worse-than-the-dinosaur-extinction-130869">in the past</a>, the current changes are occurring at an unprecedented rate. In geologic time scales, before the influence of humans, a significant <a href="https://publications.csiro.au/rpr/pub?list=BRO&pid=procite:13c02405-e8c6-466c-a400-f6137710a651">shift</a> in climate has been <a href="https://www.publish.csiro.au/book/6836/">associated</a> with an increase in fire activity in Australia. There is every reason to expect fire activity will increase with human-induced climate change as well. Humans have also changed the Australian fire landscape – both First Nations people and, for the past 200 years, European colonisers. Changes brought about by Indigenous Australians were widespread, but <a href="https://pubmed.ncbi.nlm.nih.gov/32378038/">sustainable</a>. Their methods included, for example, lighting “cool” fires in small, targeted patches early in the dry season. This reduced the chance that very large and intense fires would develop. Changes brought about by European colonisers have also been widespread – such as land clearing using fire, and fire suppression to protect human life and property. But this approach has been <a href="https://www.researchgate.net/publication/30388718_National_Inquiry_on_Bushfire_Mitigation_and_Management">far from sustainable</a>, either financially, ecologically or socially. Australia has just experienced a period of high rainfall across the continent due to a La Niña event <a href="https://climateextremes.org.au/large-scale-climate-drivers-in-australia-2022/#:%7E:text=The%20combined%20influence%20of%20a,in%20123%20years%20of%20records.">combined with</a> two other climate drivers: a negative Indian Ocean Dipole and a positive Southern Annular Mode. It means the soil is moist and plants are flourishing. Now, we’re set to enter into a drying period driven by an El Niño. The abundant plant growth leading into a dry period is likely to result in widespread bushfires across Australia. Initially, this is <a href="https://knowledge.aidr.org.au/resources/bushfire-new-south-wales-1974/">likely to occur</a> in semi-arid inland areas where grasses have flourished in the wet period, but will dry out quickly. If the drying cycle persists for two or three years, then fires might become more prevalent in forests and woodlands in temperate Australia. But an El Niño year doesn’t necessarily mean a bad bushfire season is certain. In Australia, El Niño events are associated with hotter and drier conditions, <a href="https://www.researchgate.net/publication/263018552_Multi-decadal_variability_of_forest_fire_risk_-_Eastern_Australia">leading to more days</a> of high fire danger. But large and severe forest fires also need a prolonged drought to dry out fuels, especially in sheltered gullies and slopes. Soils and woody vegetation are currently moist following the La Niña period. So El Niño and its opposite phase, La Niña, are on their own are a relatively <a href="https://research.monash.edu/en/publications/forecasting-fire-activity-in-victoria-australia-using-antecedent-">poor predictor</a> of the number and size of bushfires. <h2>Fight smarter, and be prepared</h2> Climate change will continue to test our fire management systems. And the return of an El Niño has fire crews <a href="https://www.theguardian.com/environment/2023/jun/10/australia-firefighters-fire-crews-prepare-for-return-of-el-nino-bushfire-season-smoke-hazard-reduction-burns">on alert</a>. When it comes to fire management, Australia must be much smarter than it has been for the past 200 years. This means changing the focus to holistic fire management. Throwing huge amounts of money and resources at controlling bushfires – such as <a href="https://www.canberratimes.com.au/story/7034300/govt-vows-to-get-more-firefighting-aircraft/">purchasing more</a> and larger <a href="https://www.news.com.au/technology/environment/new-weapon-to-fight-aussie-bushfires-kicks-off-service-in-wa/news-story/fa66e567e336164723cae8b98bb3ba8d">firefighting aircraft</a> – is is not sustainable or sensible. Fire is as fundamental to our environment as wind and rain. And the amount of energy released from a large bushfire will never be matched by any level of resources humans can muster. The evidence bears this out. Take, for example, <a href="https://www.publish.csiro.au/wf/WF9970221">analysis</a> of fire dynamics in two areas north and south of the US-Mexico border. Between 1920 and 1972, authorities on the US side had spent hundreds of millions of dollars on firefighting aircraft and other resources trying to suppress wildfires. This resulted in fewer wildfires than in the Mexico region. But the fires that occurred were larger and more severe. Similar patterns have occurred in Australia. For example, a <a href="https://www.researchgate.net/publication/284776990_Evidence_of_altered_fire_regimes_in_the_Western_Desert_regime_of_Australia">study</a> of burn patterns in the Western Desert region showed that after the exodus of Traditional Owners, the number of fires reduced substantially, but the fires became far bigger. <h2>Change must happen</h2> Damaging bushfires will return to Australia in the near future. The expected return of another El Niño should heighten efforts to create a more considered and sustainable fire management regime – particularly in southern Australia. Experts, including me, have <a href="https://www.forestry.org.au/wp-content/uploads/2022/11/Final-KPI-Document-v2.pdf">devised</a> <a href="https://knowledge.aidr.org.au/media/4935/nationalbushfiremanagementpolicy_2014.pdf">plans</a> to guide the shift. They include: <ul> <li>effectively managing the land with fire, including promoting Indigenous Australians’ use of fire</li> <li>engaging communities in bushfire mitigation and management</li> <li>better coordination across land, fire and emergency management agencies</li> <li>ensuring fire management is based on “best practice” approaches.</li> </ul> Australia, with its wealth of scientific knowledge and long history of Indigenous land management, should be well placed to manage fire sustainably – even with the pressures of climate change. Changing our approach will not be quick or simple, but it must be done.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/209126/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/kevin-tolhurst-am-184">Kevin Tolhurst AM</a>, Hon.
