Eight dead as hot-air balloon erupts in flames

At least eight people have died after a hot-air balloon carrying 21 passengers caught fire mid-flight over southern Brazil, in what authorities have described as a tragic accident. The incident occurred early Sunday near the coastal town of Praia Grande in Santa Catarina state. Santa Catarina governor Jorginho Mello confirmed the toll in a statement on X, writing: “Eight fatalities and 13 survivors.” Dramatic footage captured by bystanders and aired on Brazilian television showed the balloon engulfed in flames, swinging violently before the passenger basket broke off and plummeted to the ground in flames. The weather was reported to be clear at the time of the disaster. <iframe title="YouTube video player" src="https://www.youtube.com/embed/nqz8c6VS-Jo?si=cMv3w7kUfME2vRs9" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe> According to local fire officials, 13 people – including the pilot – miraculously survived and were taken to hospitals. Our Lady of Fatima hospital said five survivors were treated there; three remained in stable condition with minor injuries while two had already been discharged. Details on the other survivors were not immediately available. An investigation is now underway to determine the cause of the fire. The pilot told local media that the blaze may have started with a blowtorch used in the basket. “I don’t know if it stayed lit or if it reignited on its own, but it was the torch that started it all,” he told Jornal Razao. The pilot said he attempted an emergency landing as soon as the fire broke out and urged passengers to jump once they were close to the ground. “Once it was close to the ground, [the pilot] told the passengers to jump from the basket. But some of them couldn’t do it and the fire grew,” Tiago Luiz Lemos, a police official in Praia Grande, told reporters. Fire department official Zevir Cipriano Junior said four victims died from burns and four others died from injuries sustained in the fall. In a video statement, Governor Mello said: “We are in mourning. It’s a tragedy that happened. We will check the developments, what happened, and why it happened.” Brazilian President Luiz Inacio Lula da Silva also expressed condolences and offered federal support for the rescue and recovery efforts. Praia Grande, known for its scenic coastline, is a popular hotspot for hot-air ballooning. This is Brazil’s second fatal ballooning accident in under a week; just days earlier, a woman was killed during a flight in Sao Paulo state. Authorities say investigations will focus on safety protocols and equipment standards in the ballooning industry. Images: NBC / Youtube

It’s almost winter. Why is Australia still so hot?

<div class="theconversation-article-body"> This year, for many Australians, it feels like summer never left. The sunny days and warm nights have continued well into autumn. Even now, in May, it’s still unusually warm. Much of the southern half of the continent is experiencing both unseasonable warmth and dry conditions. This is linked to persistent high atmospheric pressure (called “blocking”) to the south and southeast of Australia. While temperatures will fall across southern Australia as we approach the winter solstice, early indications are that this winter will be a warm one. Rainfall predictions are less certain. The extra warmth we’ve experienced raises obvious questions about the influence of human-caused climate change. The warming signal is clear and it’s a sign of things to come. <h2>A warm and dry autumn for many</h2> <a href="http://www.bom.gov.au/jsp/awap/temp/index.jsp?colour=colour&time=latest&step=1&map=meananom&period=month&area=nat">March</a> and <a href="http://www.bom.gov.au/jsp/awap/temp/index.jsp?colour=colour&time=latest&step=0&map=meananom&period=month&area=nat">April</a> brought unseasonal heat to much of Australia. March was widely hot, with temperatures several degrees above normal across much of the country. But April’s heat was largely restricted to the southeast. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/666591/original/file-20250507-68-vjvcb5.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/666591/original/file-20250507-68-vjvcb5.png?ixlib=rb-4.1.0&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/666591/original/file-20250507-68-vjvcb5.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=450&fit=crop&dpr=1 600w, https://images.theconversation.com/files/666591/original/file-20250507-68-vjvcb5.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=450&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/666591/original/file-20250507-68-vjvcb5.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=450&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/666591/original/file-20250507-68-vjvcb5.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=566&fit=crop&dpr=1 754w, https://images.theconversation.com/files/666591/original/file-20250507-68-vjvcb5.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=566&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/666591/original/file-20250507-68-vjvcb5.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=566&fit=crop&dpr=3 2262w" alt="Graph of rising Australian-average temperatures in March from 1900-2025" /></a><figcaption>Australia had its hottest March on record and the heat has continued, especially in Victoria and parts of New South Wales. <a class="source" href="http://www.bom.gov.au/cgi-bin/climate/change/timeseries.cgi?graph=tmean&area=aus&season=03&ave_yr=0&ave_period=6190">Bureau of Meteorology</a></figcaption></figure> Victoria had its <a href="http://www.bom.gov.au/cgi-bin/climate/change/timeseries.cgi?graph=tmean&area=vic&season=04&ave_yr=0&ave_period=6190">warmest April</a> on record, and parts of the state experienced temperatures more than 3°C above normal across both March and April.

The area between Adelaide and Melbourne has been exceptionally dry. <a href="http://www.bom.gov.au/climate/maps/rainfall/?variable=rainfall&map=drought&period=3month&region=nat&year=2025&month=04&day=30">A drought is unfolding</a> in the region after a <a href="http://www.bom.gov.au/climate/maps/rainfall/?variable=rainfall&map=drought&period=12month&region=nat&year=2025&month=04&day=30">severe lack of rainfall</a>, with deficits stretching back over the past year or so. Western Tasmania is also suffering from a severe lack of rainfall since the start of autumn, although welcome rain fell in the past week. And it’s not just on land that unusual heat has been observed. The seas around Australia have been warmer than normal, causing severe coral bleaching to <a href="https://theconversation.com/synchronised-bleaching-ningaloo-and-the-great-barrier-reef-are-bleaching-in-unison-for-the-first-time-252906">the west and east</a> of the continent, <a href="https://www.epa.sa.gov.au/environmental_info/water_quality/harmful-algal-blooms">harmful algal blooms</a> and other ecosystem disruptions. <h2>Blocking highs largely to blame</h2> A high pressure system has dominated over the south and southeast of Australia over the past few months. High pressure in the Tasman Sea can sometimes get stuck there for a few days. This leads to what’s known as “blocking”, when the usual passage of weather systems moving from west to east is obstructed. This can lock in weather patterns for several days or even a week. Repeated blocking occurred this autumn. As winds move anticlockwise around high pressure systems in the Southern Hemisphere, blocking highs in the Tasman Sea can bring moist, onshore winds to the New South Wales and Queensland coasts, increasing rainfall. But such high pressure systems also bring drier conditions for the interior of the southeast and much of Victoria and South Australia. Often, these high pressure systems also bring northerly winds to Victoria, and this can cause warmer conditions across much of the state. High pressure systems also tend to bring more clear and sunny conditions, which increases daytime temperatures in particular. Air in high pressure systems moves down towards the surface and this process causes warming, too. Australia sits between the Pacific and Indian Oceans and is subject to their variability, so we often look there to help explain what’s happening with Australia’s climate. In autumn though, our climate influences, such as the El Niño-Southern Oscillation and the Indian Ocean Dipole, are less active and have weaker relationships with Australian climate than at other times of year. Neither of these climate influences is <a href="http://www.bom.gov.au/climate/outlooks/#/overview/influences">in a strong phase</a> at the moment. <h2>A warm winter on the cards</h2> One big question is how long the heat will last. In parts of southeast Australia, including <a href="http://www.bom.gov.au/jsp/ncc/cdio/cvg/av?p_stn_num=086071&p_prim_element_index=0&p_display_type=statGraph&period_of_avg=ALL&normals_years=allYearOfData&staticPage=">Melbourne</a>, average temperatures drop quickly at this time of year as we approach the winter solstice. However, the seasonal outlook from the Bureau of Meteorology points to a high likelihood of a relatively <a href="http://www.bom.gov.au/climate/outlooks/#/temperature/maximum/median/seasonal/0">warm winter</a>. Australians rarely escape having a winter without any significant cold spells, but the long-range forecast suggests we should anticipate above-normal temperatures on average. Both daytime maximum temperatures and nighttime minimum temperatures are expected to be above average generally this winter. <figure><iframe src="https://www.youtube.com/embed/Y5NIa7X2H-s?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Climate and water long-range forecast, issued 1 May 2025 (Bureau of Meteorology)</figcaption></figure> <h2>Global warming is here</h2> The elephant in the room is climate change. Human-caused climate change is increasing autumn temperatures and the frequency of late season heat events. As greenhouse gas emissions continue at a <a href="https://theconversation.com/global-carbon-emissions-inch-upwards-in-2024-despite-progress-on-evs-renewables-and-deforestation-243133">record pace</a>, expect continued warming and a greater chance of autumn heatwaves in future. The effect of climate change on rainfall is less clear though. For the vast majority of Australia, there is <a href="https://interactive-atlas.ipcc.ch/regional-information">high uncertainty</a> as to whether autumn will become wetter or drier as the world warms.<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/256071/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> By <a href="https://theconversation.com/profiles/andrew-king-103126">Andrew King</a>, Associate Professor in Climate Science, ARC Centre of Excellence for 21st Century Weather, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Pagan loaves, Christian bread, a secular treat: a brief history of hot cross buns

<div class="theconversation-article-body">Hot cross buns aren’t just a sweet snack that appears around Easter. They carry centuries of storytelling in their dough. From ancient gods to modern supermarkets, these sticky spiced buns have crossed many borders and beliefs. Today, you can buy them in all kinds of flavours. But their story is far richer than chocolate chips and salted caramel. <h2>Ancient beginnings</h2> In some ancient cultures, bread was more than just food. It was a symbol of faith. Ancient Greeks baked small round loaves marked with crosses to honour their gods. According to some historians, these marks could represent the four seasons or <a href="https://www.ravenhook.com/bread-blog/hot-cross-buns">four phases of the moon</a>. Jewish people have also shared special bread during holy times like Passover, and scholars have debated whether these customs influenced <a href="https://catholiccuisine.blogspot.com/2009/04/hot-cross-buns-history.html">early Christian bread traditions</a>. Pagan Saxons worshipped a spring goddess named <a href="https://en.wikipedia.org/wiki/%C4%92ostre">Eostre</a>. They baked bread during springtime festivals to celebrate new life and longer days. The name “Eostre” is where we get the English word “Easter”. Over time, some of these springtime bread traditions blended with Christian customs. <h2>From Pagan loaves to Christian buns</h2> Early Christians started marking bread with a cross to show their devotion, and ate it throughout the year. They believed <a href="https://www.smh.com.au/goodfood/easter-2016-the-history-of-hot-cross-buns-and-where-to-find-the-best-20160314-gnc8od.html">the cross kept away evil spirits</a> and helped the dough rise. Over time, the Christian view of the bread marked with the cross shifted to focus on <a href="https://theconversation.com/the-roots-of-the-easter-story-where-did-christian-beliefs-about-jesus-resurrection-come-from-221071">Jesus’ crucifixion and became associated with Easter</a>. <figure class="align-right zoomable"><figcaption></figcaption></figure> By the Middle Ages, many bakers only kept the <a href="https://catholiccuisine.blogspot.com/2009/04/hot-cross-buns-history.html">cross on Good Friday bread</a>. According to popular tales, one 12th-century English monk made spiced buns marked with a cross on Good Friday, because that day is the “<a href="https://www.cathedralatl.org/goodfaithpostings/god-defeats-violence-at-the-cross/">Day of the Cross</a>”. Monks often used spices to show <a href="https://austenvariations.com/hot-cross-buns-a-good-friday-tradition/">the day was special</a>. These <a href="https://www.lavenderandlovage.com/2012/03/baking-for-easter-the-history-of-traditional-hot-cross-buns-and-hot-cross-bun-recipe.html">spiced buns</a> helped people remember the crucifixion of Christ and the <a href="https://biblestudylessons.net/articles/BurialSpices.html">spices used in his burial</a>. In 1592, Queen Elizabeth I restricted the sale of spiced bread and buns, perhaps because of religious tensions. England had broken away from the Catholic Church, and new Church of England officials worried that “holy” buns looked too much like <a href="https://www.english-heritage.org.uk/easter/a-history-of-hot-cross-buns/">Catholic superstition</a>. Others say it was an issue of bread prices and profits. Then again maybe they were just <a href="https://www.sandylanefarm.co.uk/c/bakery/easter-hot-cross-buns">too special</a> for just everyday. Under these laws, commercial bakers could only make spiced bread on Christmas, Easter and for funerals. <h2>Good Friday and magic buns</h2> By the 18th century, English street vendors sold “hot cross buns” on Good Friday. We even see an <a href="https://en.wikipedia.org/wiki/Hot_Cross_Buns_(song)">old rhyme</a> about them in Poor Robin’s Almanac in 1733, which says: <blockquote> Good Friday comes this month, the old woman runs, With one a penny, two a penny, hot cross buns. </blockquote> Soon, people believed these Good Friday buns had <a href="https://anglicanfocus.org.au/2020/04/05/raisin-the-curtain-on-the-humble-hot-cross-bun/">magical powers</a>. Some hung them from kitchen rafters, believing they would never go mouldy. They kept them for protection against evil or illness. If someone felt sick, they <a href="https://food52.com/blog/19462-were-hot-cross-buns-the-first-food-fad-a-brief-and-fascinating-history?srsltid=AfmBOorsFIsP1cYUDsCRMIshNIU7Lh2Gq00L0OOgL-VwSAhw_O5Uc7I8">crumbled part of an old hot cross bun</a> into water, hoping it would cure them. Others placed buns in their grain stores to keep pests away. These beliefs might sound odd today, but they were part of daily life for many. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/657956/original/file-20250327-56-yehmhv.jpeg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/657956/original/file-20250327-56-yehmhv.jpeg?ixlib=rb-4.1.0&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/657956/original/file-20250327-56-yehmhv.jpeg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=740&fit=crop&dpr=1 600w, https://images.theconversation.com/files/657956/original/file-20250327-56-yehmhv.jpeg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=740&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/657956/original/file-20250327-56-yehmhv.jpeg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=740&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/657956/original/file-20250327-56-yehmhv.jpeg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=930&fit=crop&dpr=1 754w, https://images.theconversation.com/files/657956/original/file-20250327-56-yehmhv.jpeg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=930&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/657956/original/file-20250327-56-yehmhv.jpeg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=930&fit=crop&dpr=3 2262w" alt="Three children and their mother reach for buns in a basket." /></a><figcaption>This hand-coloured etching from 1799 shows a woman selling hot cross buns in London. <a class="source" href="https://www.metmuseum.org/art/collection/search/739498">The Metropolitan Museum of Art</a></figcaption></figure> In Victorian England, people <a href="https://blog.library.villanova.edu/2016/03/24/hot-cross-buns-a-lenten-treat/">exchanged hot cross buns with friends</a> on Good Friday and said, “Half for you and half for me, between us two good luck shall be”. Whatever ancient superstition the cross once warded off, today it’s the flavour roulette that keeps us coming back. Proof that tradition now serves taste, not fear. <h2>An enduring symbol</h2> Traditional buns contain dried fruit and spices like cinnamon and nutmeg, but many modern versions <a href="https://bakingwithgranny.co.uk/recipe/chocolate-chip-hot-cross-buns/">swap sultanas for chocolate chips</a> or add flavours like salted caramel, orange – or even <a href="https://vegemite.com.au/recipe/cheesy-vegemite-hot-cross-buns/#newsletter">Vegemite and cheese</a>. They have become a secular treat. Yet the crisscross pattern remains on top, hinting at the Christian origins. When you smell a fresh batch of these buns, you’re sharing an experience people enjoyed centuries ago. Ancient Egyptians, Greeks, Poles, Romans, Saxons, medieval monks and 18th-century street sellers all had their versions of spiced, crossed bread. Each group gave the buns its own meaning, from honouring gods to celebrating Christ’s crucifixion and resurrection. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/659209/original/file-20250402-62-oa1v6d.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/659209/original/file-20250402-62-oa1v6d.jpg?ixlib=rb-4.1.0&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/659209/original/file-20250402-62-oa1v6d.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=603&fit=crop&dpr=1 600w, https://images.theconversation.com/files/659209/original/file-20250402-62-oa1v6d.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=603&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/659209/original/file-20250402-62-oa1v6d.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=603&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/659209/original/file-20250402-62-oa1v6d.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=758&fit=crop&dpr=1 754w, https://images.theconversation.com/files/659209/original/file-20250402-62-oa1v6d.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=758&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/659209/original/file-20250402-62-oa1v6d.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=758&fit=crop&dpr=3 2262w" alt="Colour illustration." /></a><figcaption>A woman giving hot cross buns to two children, in an illustration from 1899. <a class="source" href="http://blogs.bl.uk/untoldlives/2015/04/hot-cross-buns.html">British Library</a></figcaption></figure> Eating hot cross buns at Easter also shows how traditions change with each generation.

To keep your cool in a heatwave, it may help to water your trees

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/gregory-moore-1779">Gregory Moore</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> <a href="https://knowledge.aidr.org.au/resources/heatwave/">Heatwaves</a> are among the world’s <a href="https://wmo.int/topics/heatwave#:%7E:text=Impact,died%20from%20heat%2Drelated%20stress.">deadliest</a> weather hazards. Every year, vast numbers of people are <a href="https://www.sciencedirect.com/science/article/pii/S1462901114000999">killed by heat stress</a> and it can worsen health problems such as <a href="https://www.who.int/news-room/fact-sheets/detail/climate-change-heat-and-health">diabetes, asthma and heart disease</a>. Unfortunately, the bitumen roads, brick and concrete structures and roofing tiles in cities can absorb and retain vast amounts of heat, much of which is released after the sun has set. This creates what’s known as the <a href="https://www.climatechange.environment.nsw.gov.au/impacts-climate-change/built-environment/urban-heat">urban heat island effect</a>. In fact, temperatures can be <a href="https://www.climatechange.environment.nsw.gov.au/impacts-climate-change/built-environment/urban-heat#:%7E:text=and%20rural%20environments.-,In%20large%20cities%2C%20average%20temperatures%20can%20be%201%C2%B0C,parts%20experiencing%20even%20higher%20temperatures.">significantly higher in cities</a> than in <a href="https://greenly.earth/en-us/blog/ecology-news/6-key-things-to-know-about-urban-heat-islands">surrounding or rural areas</a>. Trees and greenspace can <a href="https://wwf.org.au/blogs/trees-lower-temperatures-in-a-sydney-street-by-20-degrees/">drive down urban temperatures</a> – but they must be able to draw water from the soil to achieve these massive cooling effects. In other words, it can sometimes be helpful to water your trees during a heatwave. <h2>How trees keep us cool (and no, it’s not just about shade)</h2> Trees reduce urban temperatures in two significant ways. One is by the shade they provides and the other is through their cooling effect – and no, they’re not the same thing. Water is taken up via a plant’s roots, moves through the stems or trunks and is then misted into the air from the leaves through little holes called stomata. This is called transpiration, and it helps cool the air around leaves. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&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/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=615&fit=crop&dpr=1 600w, https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=615&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=615&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=772&fit=crop&dpr=1 754w, https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=772&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=772&fit=crop&dpr=3 2262w" alt="A diagram shows how transpiration happens." /></a><figcaption>Transpiration helps cools the air around a plant’s leaves. <a class="source" href="https://www.shutterstock.com/image-vector/transpiration-stages-plants-roots-absorb-water-1856372440">grayjay/Shutterstock</a></figcaption></figure> Water can also evaporate from soil and other surfaces. The combined loss of water from plants and soil is called evapotranspiration. The cooling effects of evapotranspiration vary but are up to <a href="https://www.sciencedirect.com/science/article/pii/S2095311913605432#:%7E:text=Our%20literature%20review%20suggests%20that,ways%20of%20reducing%20urban%20temperatures">4°C</a>, depending on other environmental factors. <h2>Watering your trees</h2> If heatwaves occur in generally hot, dry weather, then trees will provide shade – but some may struggle with transpiration if the soil is too dry. This can reduce the cooling effect of trees. Keeping soil moist and plants irrigated, however, can change that. The best time to irrigate is early in the morning, as the water is less likely to evaporate quickly before transpiration can occur. You don’t need to do a deep water; most absorbing roots are close to the <a href="https://theconversation.com/here-are-5-practical-ways-trees-can-help-us-survive-climate-change-129753">surface</a>, so a bit of brief irrigation will often do the trick. You could also recycle water from your shower. Using mulch helps trap the water in the soil, giving the roots time to absorb it before it evaporates. All transpiring plants have a cooling effect on the air surrounding them, so you might wonder if trees have anything special to offer in terms of the urban heat island effect and heatwaves. Their great size means that they provide much larger areas of shade than other plants and if they are transpiring then there are greater cooling effects. The surface area of tree leaves, which is crucial to the evaporative cooling that takes place on their surfaces, is also much greater than many other plants. Another advantage is that trees can be very long lived. They <a href="https://www.epa.gov/heatislands/using-trees-and-vegetation-reduce-heat-islands">provide shade, cooling and other benefits</a> over a very long time and at relatively low cost. <h2>Not all trees</h2> All that said, I don’t want to overstate the role of urban trees in heatwaves when soils are dry. Some trees cease transpiring early as soils dry, but <a href="https://auf.isa-arbor.com/content/39/3/109">others will persist</a> until they wilt. Careful tree selection can help <a href="https://treenet.org/resource/it-isnt-rocket-science-street-trees-can-make-a-difference-in-climate-change/">maximise the cooling effects</a> of the urban forest. Trees that suit the local soil and can cope with some drying while maintaining transpiration can provide greater cooling And, of course, it is important to follow any <a href="https://www.water.vic.gov.au/for-households/water-restrictions-and-rules/permanent-water-saving-rules">water restriction</a> <a href="https://www.nsw.gov.au/environment-land-and-water/drought/water-restrictions">rules</a> or <a href="https://www.sydneywater.com.au/water-the-environment/what-we-are-doing/water-wise-guidelines.html">guidelines</a> that may be operating in your area at the time. <h2>Trees keep us cool</h2> Despite the clear benefits trees can provide in curbing heat, tree numbers and canopy cover are declining annually in many Australian cities and towns. Housing development still occurs without proper consideration of how trees and greenspace improve residents’ quality of life. It is not an either/or argument. With proper planning, <a href="https://theconversation.com/adelaide-is-losing-75-000-trees-a-year-tree-removal-laws-must-be-tightened-if-we-want-our-cities-to-be-liveable-and-green-216990">you can have both</a> new housing and good tree canopy cover. We should also be cautious of <a href="https://au.news.yahoo.com/trees-butchered-by-power-company-highlight-common-problem-its-sad-012952515.html?guccounter=1">over-pruning</a> urban trees. Trees cannot eliminate the effects of a heatwave but can mitigate some of them. Anything that we can do to mitigate the urban heat island effect and keep our cities and towns cooler will reduce heat-related illness and associated medical costs.<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/246486/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/gregory-moore-1779">Gregory Moore</a>, Senior Research Associate, School of Agriculture, Food and Ecosystem Sciences, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why the royal family is set to receive an eye-watering pay increase

The members of the British royal family are set to receive a record-breaking pay increase, funded by British taxpayers. From April 2025, the amount the royals will receive from the Sovereign Grant - funded by the UK’s public purse – will jump by a whopping £45 million (A$88 million), to £132 million ($260 million). Not everyone is happy about this enormous pay increase, as CEO of Republic Graham Smith said that while the UK remains in the clutches of the cost of living crisis, it is not the time for such a hefty increase to one of the richest families in the world. “This is public money, all of this money comes from the government, at a time when the government is not able to properly fund schools, hospitals police … It is scandalous,” Smith told <a href="https://www.townandcountrymag.com/society/tradition/a63330811/british-royal-family-money-finances-2025/" target="_blank" rel="noopener">Town & Country</a>. “Not only should it not be going up at all, it should be going down.” The increase was first announced last year, with Buckingham Palace officials saying at the time that a huge chunk of that extra cash will be put towards the £369 million ($728 million) bill for long-planned, necessary Palace renovations. The exact amount that is being allocated from this year’s Grant for the work has not been made public. The Grant was established in 2012 in order to help the royal family pay for expenses related to their official duties, with the vast majority usually spent on property maintenance and staffing. When the Grant first came into effect, there were many more working royals which required a larger pool of funding. Now that the royal roster has been stripped back, royal author Richard Palmer believes the public is now “getting less for their money”. He told Town & Country, “I do think that the monarchy in general does a good job for the country and is part of the glue that binds us all together but that doesn’t mean that as an institution, as individuals, they should be able to avoid criticism. They are not above scrutiny.” Image credits: Shutterstock

The anatomy of a hot flush – and whether it can really make your head steam

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/michelle-spear-172043">Michelle Spear</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> A hot flush is a phenomenon as disruptive as it is commonplace. One moment, life proceeds as usual. The next, a wave of heat rises, spreading from the chest to the face – leaving behind flushed skin and beads of sweat. For many, this sudden warmth is accompanied by an <a href="https://www.mayoclinic.org/diseases-conditions/hot-flashes/symptoms-causes/syc-20352790">accelerated heartbeat and a faint sense of unease</a>. Though brief – typically lasting anywhere from 30 seconds to five minutes – its intensity can be startling and made worse by unpredictable timing. A recent viral video has brought attention to just how intense a hot flush can be. The video depicts a woman named Tracey Monique <a href="https://uk.style.yahoo.com/menopause-hot-flush-flash-symptoms-134536113.html?guccounter=1">experiencing a hot flush</a> while at an outdoor event. In the video, her head is literally steaming. The sight of wisps of vapour escaping her head highlighted the dramatic effects of this common <a href="https://www.nhs.uk/conditions/menopause/symptoms/">perimenopausal symptom</a>. Often misunderstood or trivialised, the image of a hot flush brings fresh attention to a phenomenon that affects an estimated <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/introduction-to-menopause">75% of people experiencing perimenopause</a>. The video has also sparked debate on social media – reflecting the complexity of hot flushes themselves. Some argue the steam escaping Monique’s head was caused by her removing her hat while being in the cold. But many women have commented, saying the video perfectly encapsulates what a hot flush feels like. Let’s take a look at what’s actually happening during a hot flush and why they can feel so severe. <h2>Hormonal instigators</h2> At the heart of a hot flush lies oestrogen – a hormone critical role in regulating body temperature in women. Oestrogen directly <a href="https://my.clevelandclinic.org/health/body/22566-hypothalamus">influences the hypothalamus</a>, a small but essential structure in the brain often referred to as the <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6397692/">body’s thermostat</a>. The hypothalamus monitors and adjusts body temperature to maintain balance. Under normal circumstances, the hypothalamus keeps the body within a narrow temperature range – adjusting blood flow and sweat production as needed. But during perimenopause, <a href="https://www.rcog.org.uk/for-the-public/browse-our-patient-information/treatment-for-symptoms-of-the-menopause/?utm_source=chatgpt.com">oestrogen levels fluctuate</a> unpredictably and eventually decline. These hormonal shifts disrupt the hypothalamus’s ability to maintain its usual set temperature. Declining oestrogen levels also make the hypothalamus overly sensitive to small changes in body temperature – misinterpreting these as <a href="https://pubmed.ncbi.nlm.nih.gov/31001050/">signs of overheating</a>. This triggers an exaggerated response aimed at cooling the body down: a hot flush. The result is a sudden dilation of blood vessels, particularly in the skin of the upper body, to allow heat to radiate outward. Simultaneously, sweat glands activate – intensifying the sensation of heat. <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3956631/">Luteinising hormone</a>, which primarily regulates ovulation, also plays a secondary role in hot flushes. As oestrogen levels decline, the pituitary gland (which regulates key hormones that control growth, reproduction and metabolism) <a href="https://academic.oup.com/endo/article/163/2/bqab268/6490154">releases erratic surges</a> of lutenising hormone. These spikes appear to further heighten the hypothalamus’s sensitivity, amplifying its misinterpretation of normal body temperature as overheating. <h2>The cooling response</h2> During a hot flush the hypothalamus sends urgent signals to the autonomic nervous system, which governs involuntary functions such as heart rate, blood pressure and sweating. This prompts blood vessels near the skin to dilate – a <a href="https://www.ncbi.nlm.nih.gov/books/NBK557562/">process called vasodilation</a>. This allows more blood to flow to the surface to release heat. This is why the face, neck and chest can feel intensely warm and look visibly flushed during a hot flush. Almost simultaneously, the hypothalamus activates sweat glands in the upper body. Sweating is meant to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6773238/">cool the body</a> through evaporation. In cold environments, this sweat may produce visible steam – as seen in Monique’s viral video. But once the hypothalamus realises the body isn’t actually overheated, vasodilation subsides and blood vessels return to their normal state. But the rapid cooling effect from sweating can leave women <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4612529/">feeling chilled</a>. This creates a rollercoaster of sensations during and after the hot flush. This sequence – heat, flush, sweat and chill – reflects the body’s struggle to regain equilibrium in response to a misfiring thermostat. <h2>The debate</h2> While the sensation of heat is undeniable, whether hot flushes significantly raise skin temperature remains debated. <a href="https://www.maturitas.org/article/0378-5122(79)90009-4/abstract">Thermographic studies</a>, which use infrared imaging to measure heat patterns and surface temperature, have demonstrated measurable skin temperature rises – particularly in the face, neck and chest. But other research has found only <a href="https://www.obgproject.com/2019/07/24/are-menopausal-hot-flushes-really-triggered-by-core-temperature/">minor or negligible changes</a> in skin temperature. This raises questions about whether the perception of heat correlates directly with physiological changes. Critics suggest that the sensation of heat stems more from the brain’s altered thermoregulation than from actual warming of the skin. Tools such as thermographic imaging may also miss subtle or transient temperature changes – or these changes may be masked by sweat evaporation. It may also be the case that <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4612529/">skin temperature changes</a>, like other perimenopausal symptoms, vary widely between people. The <a href="https://bmcwomenshealth.biomedcentral.com/articles/10.1186/1472-6874-9-13">variability in oestrogen levels</a> contributes significantly – with those experiencing more erratic hormonal changes often reporting more intense or frequent flushes. Factors such as <a href="https://www.mdpi.com/2072-6643/16/5/655">genetics, lifestyle and environmental triggers</a>, all add to the diversity of experiences and how intense symptoms might be. Hot flushes are a complex interplay of hormonal, neurological and vascular responses. While the scientific debate about skin temperature changes remains unresolved, the lived experience of heat and discomfort is undeniable. For many, these symptoms are disruptive and even debilitating, profoundly affecting daily life. Monique’s viral video, with the striking image of steam rising from her head, has resonated deeply with countless women – offering stark visual evidence of what they’ve felt but often struggled to articulate. Understanding the anatomy of a hot flush not only sheds light on its mechanisms but also underscores the importance of empathy and tailored approaches to managing this multifaceted symptom.<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/244452/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/michelle-spear-172043">Michelle Spear</a>, Professor of Anatomy, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Donald Bradman's baggy green sells for eye-watering price

Sir Donald Bradman's baggy green that he wore in his final Australian Test series has fetched nearly half a million at auction. The cap was worn by Bradman during the 1947-48 series, when the Indian team played on Australia soil for the first time in history. The baggy green fetched a whopping $390,000, with the final price totalling $479,700 including auction costs. It attracted significant interest from potential buyers from both Australia and overseas, with the winning buyer coming out on top after a 10 minute flurry at Bonhams Auction House in Sydney on Tuesday evening. The auction house described the cap as "sun faded and worn", with "some insect damage" and "some loss to edge of peak". The cap was also advertised as “the only known Baggy Green” to have been worn by Bradman during the series, where he cored 715 runs in six innings at an average of 178.75, with three centuries and a double-hundred. Bradman had gifted it to India's team manager at the time, who then gave it to the team's wicket keeper. While it is currently not known who placed the winning bid, the cap itself has particular significance to Indian fans, as the series took place just months after the country gained independence. For Aussie fans, the cap was worn during Bradman's final game on Australian soil, with the cricket legend embarking on a farewell tour of England afterwards. This is not the first cap of Bradman's to go under the hammer, with the cap he wore during his 1928 Test debut fetching over $450,000 plus fees in 2020. The late Shane Warne's baggy green currently holds the record for sale at auction, after selling for $1m when auctioned off in 2020. Image: Design Pics Inc/ Shutterstock Editorial

Don’t like drinking plain water? 10 healthy ideas for staying hydrated this summer

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Have you heard the saying “water is life?” Well, it’s true. Water is an <a href="https://www.hsph.harvard.edu/nutritionsource/water/">essential nutrient</a>. Our body cannot produce sufficient water to live, so we need to consume water through food and fluids to survive. Maintaining hydration is one of the most fundamental components of good health. But lots of people don’t like drinking plain water much. The good news is there are many other healthy ways to help you stay hydrated. <h2>Why hydration is important</h2> Water is vital for many aspects of body functioning. About half our blood is “blood plasma”, which is over 90% water. Blood plasma is essential for carrying energy, nutrients and oxygen to the cells in the body that need it most. Water helps to remove waste products via the kidneys. It also helps keep joints lubricated, the digestive system functioning, the body’s temperature controlled and skin plump and strong. If you don’t consume enough water, you may experience symptoms of dehydration such as headaches, dizziness, tiredness, low concentration, constipation and a dry mouth. Being severely dehydrated increases the risk of <a href="https://www.kidney.org/atoz/content/kidneystones">kidney stones</a> and <a href="https://www.healthdirect.gov.au/urinary-tract-infection-uti">urinary tract infections</a>. If you feel thirsty, it means your body is already <a href="https://my.clevelandclinic.org/health/treatments/9013-dehydration#:%7E:text=If%20you're%20thirsty%2C%20you,life%2Dthreatening%20illnesses%20like%20heatstroke.">mildly dehydrated</a>, so make sure you pay attention to what your body is telling you. <h2>How much fluid do you need?</h2> The amount of fluid we need changes as we age. Relative to our body weight, our needs decrease. So, a newborn baby has higher fluid needs (per kilogram body weight) than their parent, and older adults have lower fluid needs than younger adults. Fluid requirements are related to metabolic needs and vary from person-to-person. The normal turnover of water in adults is approximately 4% of total body weight per day. So, for example, if you weigh 70 kilograms, you’ll lose about 2.5 to 3 litres of water a day (not including sweating). This means you will need to consume that amount of water from food and drinks to maintain your hydration. Eight cups (or two litres) a day is often <a href="https://www.npr.org/2022/09/21/1124371309/busting-common-hydration-water-myths?utm_source=npr_newsletter&utm_medium=email&utm_content=20221016&utm_term=7386723&utm_campaign=health&utm_id=31926817&orgid=&utm_att1=">mentioned</a> as the amount of water we should aim for and a nice way to track your intake. But it doesn’t account for individual variation based on age, gender, body size and activity levels. Alcohol is a diuretic, which means it dehydrates the body by promoting water loss through urine. This fluid loss is a key factor that contributes to the severity of a hangover. Always have a glass of water in between alcoholic drinks to help stay hydrated. Caffeinated drinks (like tea and coffee) only have a mild diuretic effect. For most healthy adults, it’s okay to consume up to 400 mg of caffeine a day – that’s about four cups of coffee or eight cups of tea. If you drink more than this, it may impact your hydration levels. To check your specific requirements, check out the Australian <a href="https://www.nrv.gov.au/nutrients/water">guidelines</a> for fluid intake. <h2>People who should take extra care</h2> Some people are at greater risk of the harmful health effects from dehydration and need to pay special attention to their fluid intake. The highest priority groups are babies, young kids, pregnant women, and older adults. These groups are at greater risk for many reasons, including relatively higher water needs per kilo of body weight, reduced ability to detect and respond to symptoms of dehydration, and barriers to consuming fluids regularly. Family and friends can play an important role in <a href="https://www.agedcareguide.com.au/information/hydration-for-elderly-people-and-the-dangers-of-dehydration">supporting loved ones</a> to maintain hydration, especially during warm weather. <h2>Ten ideas for keeping fluids up this summer</h2> <ol> <li> Download a water reminder app on your phone This will help keep you on track during the day and give you digital “high fives” when you hit your water goals. </li> <li> Add sugar-free flavouring Try a sugar-free fruit infusion in your water to make it more appealing. Prepare a jug in the refrigerator and infuse it overnight so it’s chilled for you the next day. Fill it up and take it everywhere with you! </li> <li> Add some fresh fruit Add some slices of lime, lemon, berries, pineapple or orange to your water bottle for some natural flavouring. If the bottle is kept in a fridge, the fruit will stay fresh for about three days. </li> <li> Make a jug of iced tea (not the bottled stuff) There are many great sugar-free recipes online. Tea contributes to fluid intake too. For green and black teas, brew in boiling water then cool overnight on the bench before refrigerating. Fruit teas can be made using cold water immediately. </li> <li> Add a dash of cordial to your water A small amount of cordial in your water is a healthier alternative to drinking a sugar-sweetened soft drink or fruit juice. Diet cordials have less added sugar again. </li> <li> Make a fruit ‘slushie’ Combine fresh fruit, ice and water at home in the morning and sip to increase your fluid intake for the day. </li> <li> Buy a soda maker for your home Some people find plain water tastes better with bubbles. Sparkling mineral water is great too, as long as there is no added sugar or sweeteners. </li> <li> Before you eat anything, have a glass of water Make it a rule with yourself to have a glass of water before every snack or meal. </li> <li> Eat water-rich fruits and vegetables Many fruits and vegetables have a high water content. Some of the best include berries, oranges, grapes, carrots, lettuce, cabbage, spinach and melons. Keep a container full of cut-up fruit to snack on in your fridge. </li> <li> Use a water bottle Take it with you during the day and keep it by your bed overnight. </li> </ol> <h2>A tip on water bottles</h2> Water bottles are everywhere and sometimes seem to offer <a href="https://www.refinery29.com/en-au/emotional-support-water-bottle-girlies-tiktok-trend">emotional support</a> as well as hydration. Having a water bottle you enjoy using can go a long way in helping you keep up your fluids during the day. Pay attention to the material of the water bottle and use one that helps you form good habits. Some people prefer metal water bottles as they can keep water cooler for longer (others feel like they are camping). Some prefer glass bottles because the water isn’t affected by any flavours from the container (others fear breaking the glass). Consider the practical aspects, too: Will it fit in your bag? Will it be light enough to carry with you? Can you “chug” on it when you’re exceptionally thirsty? Does the lid require screwing? How durable is it in preventing leaks? Do some <a href="https://www.marthastewart.com/7842071/best-water-bottles-hydration">homework</a> on your water bottle, an essential accessory! <a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, Professor of Community Health and Wellbeing, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, Dietitian and Researcher, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Major twist in probe into water polo coach's death

A probe into the tragic death of a water polo coach at St Andrew's Cathedral School has revealed an astonishing twist in the investigation. Lilie James, 21, was found dead inside a gymnasium bathroom at the Sydney school on October 25th last year, as police issued a warrant for Paul Thijssen's arrest in connection to her death. A school staffer let police officers into the building at Town Hall Square, where Lilie's "unrecognisable" body was found, left with "serious head injuries". In the days after Lilie's death, police established a second crime scene at The Gap in Sydney's east where they recovered Thijssen's body. Now, as a probe into her death continues, insiders have revealed to Daily Mail Australia that St Andrews Cathedral School principal Dr Julie McGonigle has been told the school will not be considered an "interested party" at the coronial inquiry into the deaths. The exclusion comes despite teachers and students having intimate knowledge and involvement with Ms James and school hockey coach Thijssen prior to the murder, and school staff having assisted in the discovery of the horrific crime scene. School principal Dr McGonigle revealed in her latest Head of School Newsletter that "at this stage, the State Coroner does not consider St Andrew's Cathedral School to have sufficient interest in this matter to be considered an interested party, pursuant to the Coroners Act". The inquest into the deaths of Lilie Anne James and Paul Thomas Stephan Thijssen will be held over three days from March 18th next year. Image credits: Facebook

"Green cordial" water in Sydney harbour baffles residents

A bay in Sydney Harbour has turned neon green, with authorities currently investigating the cause. Locals were baffled when they saw the bay along Hipwood Street in Kirribilli, near Milsons Park, turn bright green at about 3pm on Wednesday, with many calling the incident "unusual". Firefighters said they were "alerted to a large spill of fluorescent green material flowing into the harbour". One local described the water as "green cordial" and said it resembled "radioactive stuff you see in superhero movies". NSW Fire and Rescue then conducted several tests and said the water is not toxic and is currently not harming the environment. The Fire and Rescue team are now trying to flush out the green substance, and said that the incoming rain should help turn the water colour back to normal. Another resident told 9News that they had seen green water in a stormwater drain at Anderson Park, along Clark Road, on Tuesday, before the green colour spread to the bay on Wednesday. Later in the afternoon, a North Sydney Council spokeswoman confirmed that were no major pollutants in the green water: “At this stage our engineers believe the substance is likely to be fluorescein, which is used as a dye for plumbing works. Fluorescein is a non-toxic substance and breaks down with UV light. The green colour is a feature that makes it easy to trace.” Green water was also spotted in Neutral Bay on Wednesday according to another local. Image: Nine

Travel Trouble

200-year-old message in a bottle unearthed

In a discovery that has the archaeology world buzzing (and possibly rolling its ancient eyes), a team of student volunteers in northern France has unearthed something rather unexpected during their dig at a Gaulish village. While they were hoping for the usual – ancient pottery shards, perhaps a coin or two – they instead stumbled upon what can only be described as the 19th-century equivalent of a DM in a bottle. The scene played out like a low-budget historical drama: volunteers painstakingly sifting through centuries-old dirt on the cliff-tops near Dieppe when, voilà! They found an earthenware pot containing a small glass vial, like something you might see in a vintage pharmacy, but with fewer essential oils and more existential surprises. Guillaume Blondel, the team leader and head of the archaeological service for the nearby town of Eu, was immediately intrigued. “It was the kind of vial that women used to wear around their necks containing smelling salts,” he explained, before casually dropping the bombshell: inside the vial was a note. Cue dramatic music. After what we can only assume was a long, suspenseful pause, Blondel and his team opened the note, which turned out to be written by none other than P.J. Féret, a 19th-century intellectual who clearly had a flair for both excavation and theatrics. The note, written with all the panache of a man who had just unearthed Caesar’s salad fork, read: "P.J. Féret, a native of Dieppe, member of various intellectual societies, carried out excavations here in January 1825. He continues his investigations in this vast area known as the Cité de Limes or Caesar’s Camp." Naturally, Blondel was floored. “It was an absolutely magic moment,” he said, no doubt imagining Féret winking at him from the beyond. “We knew there had been excavations here in the past, but to find this message from 200 years ago? It was a total surprise.” Local records confirm that P.J. Féret was indeed the real deal. He wasn’t just a dabbler in dirt – he was a notable dabbler in dirt who had conducted an earlier dig at the site in 1825. In a stroke of irony not lost on Blondel, he mused, “Most archaeologists prefer to think that there won’t be anyone coming after them because they’ve done all the work.” Féret, however, clearly believed in leaving a trail of breadcrumbs – or, in this case, a literal note in a bottle, just to remind future archaeologists that he got there first. Féret: 1, Modern Archaeology: 0. Of course, this whole affair raises some important questions: Did Féret expect someone to find this? Did he laugh to himself as he buried it, imagining Blondel’s reaction? Did Féret know how cliff erosion would eventually turn his humble Gaulish village into a treasure trove for future archaeologists? Or was he simply trolling them from the past? Whatever the case, Féret’s note may not have contained ancient secrets, but it certainly delivered some 19th-century sass. And if we’ve learned anything from this dig, it’s this: archaeology isn’t just about discovering the past – it’s also about being occasionally roasted by it. As Blondel and his team continue their emergency dig (which was ordered due to cliff erosion eating away at the site like a bad buffet), they’ve already uncovered a number of artefacts, mostly pottery, from around 2,000 years ago. But will any of them have the audacity to leave a note for the archaeologists of 2225? We’ll have to wait and see. In the meantime, Féret is probably laughing somewhere in the afterlife, shaking his head and muttering, “Amateurs”. Images: Guillaume Blondel / Facebook

Crowds, water guns and protests: could ‘slow tourism’ be the answer to an overtourism backlash?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/amy-errmann-1360032">Amy Errmann</a>, <a href="https://theconversation.com/institutions/auckland-university-of-technology-1137">Auckland University of Technology</a> With overtourism in the spotlight as the travel industry continues to rebound after the pandemic, popular destinations around the world are feeling the strain.

Frustrated locals are pushing back – from <a href="https://www.nzherald.co.nz/travel/barcelona-locals-spray-tourists-with-water-guns-during-protest-over-housing-costs/FUFHXKO5X5F5NNPSU6ELNVGSIA/">spraying water at tourists </a> in Barcelona to <a href="https://adventure.com/venice-locals-squatting-against-overtourism-photography/">organising protests in Venice</a>. As the northern hemisphere high season ends, Aotearoa New Zealand is preparing for an influx of visitors ahead of its summer tourism season. And much like those other <a href="https://www.nytimes.com/2024/09/08/world/europe/greece-cruise-ships-tourists-islands.html">tourist hotspots</a>, the government is looking at how to manage the negative effects of tourism on local communities and the environment. This includes tripling the <a href="https://www.theguardian.com/world/article/2024/sep/04/new-zealand-to-nearly-triple-tourist-tax-for-international-visitors">international tourist tax</a> from NZ$35 to $100. The aim of the increase is to <a href="https://www.theguardian.com/world/2022/aug/11/new-zealand-tourism-minister-makes-pitch-to-the-rich-as-he-spurns-10-a-day-travellers">attract tourists</a> who are more mindful of their impact and willing to contribute to its mitigation, while also <a href="https://theconversation.com/welcome-to-nz-now-pay-up-the-risks-and-rewards-of-raising-the-foreign-tourist-tax-232138">reducing visitor numbers</a> to protect the country’s unique landscapes and cultures. But are there other ways the tourism industry can evolve to ensure benefits for both travellers and the communities they are visiting? So called “slow travel” could be the answer. <h2>Hunting the perfect photo</h2> Overtourism isn’t just about too many people in one place. It’s also about how people travel. <a href="https://edition.cnn.com/travel/social-media-tourism-effect-scn-wellness/index.html">Instagram-famous</a> landmarks draw massive crowds, <a href="https://www.rnz.co.nz/news/national/406195/visitors-ignore-ban-continue-to-visit-mermaid-pools-in-northland-hapu">disrupting local life</a> and sometimes even <a href="https://www.nzherald.co.nz/travel/vermot-town-famous-for-fall-foliage-bans-instagram-tourists-from-streets/BHKEYKKUTNHORFT6QCZ5TW333A/#google_vignette">leading to closures</a>. Travellers often pack their itineraries with as many sights as possible, racing from one place to another in a frenzy to capture the perfect photo. This hurried approach not only creates <a href="https://www.cntraveler.com/galleries/2015-06-19/barcelona-bhutan-places-that-limit-tourist-numbers">congestion</a> but also limits <a href="https://www.nature.com/articles/s41599-024-02859-z">meaningful engagement with the destination</a>. And it’s not just a numbers game. The way tourists behave also plays a critical role. A <a href="https://www.rnz.co.nz/national/programmes/ninetonoon/audio/2018690535/tropical-trash-the-impact-of-holidaying-in-the-pacific">2019 report</a> from the United Nations raised concerns about trash from tourists in developing small island states, including the Pacific Islands. According to the report, a tourist visiting these communities produced about 7kg of waste a day, compared to about 2.5kg produced by a local. The issue is not necessarily about travelling less, but about <a href="https://www.sciencedirect.com/science/article/pii/S2211973623000284">travelling more responsibly</a>. The tourism industry needs to be encouraging travel habits that allow both visitors and locals to enjoy tourism without compromising the integrity of the destination. <h2>The rise of slow travel</h2> Mindfulness – being fully present in the moment – has gained popularity since the 1970s. The concept has influenced a number of sectors, including <a href="https://slowfoodauckland.co.nz/">slow food</a>, <a href="https://ourwayoflife.co.nz/slow-fashion-101-what-to-buy-and-what-to-avoid-to-reduce-your-clothing-footprint/">slow fashion</a>, and now <a href="https://www.lakewanaka.co.nz/wanaka-stories/how-to-be-a-slow-mindful-traveler-in-wanaka/">slow travel</a>. It’s about <a href="https://link.springer.com/chapter/10.1007/978-3-031-63569-4_44#:%7E:text=Slow%20travel%2C%20mindful%20travel%2C%20or,spiritual%20well%2Dbeing%20of%20people">experiencing destinations</a> at a relaxed pace, focusing on deeper connections with local cultures and sustainability. This often means <a href="https://guestnewzealand.com/about-us/eco-travels-new-zealand/">staying longer in fewer places</a> and choosing eco-friendly transport. Understanding slow travel and mindfulness is important because they create <a href="https://www.forbes.com/sites/rogersands/2024/06/08/the-beauty-of-slow-travel/">richer, more memorable experiences</a>. Fast, <a href="https://www.sciencedirect.com/science/article/pii/S0261517724000487">hectic travel</a> often leaves little positive impact. Slow immersive travel, on the other hand, fosters lasting memories and reduces overtourism, pollution and cultural damage. <a href="https://www.tandfonline.com/doi/full/10.1080/00913367.2024.2325144">Research</a> shows when we consciously immerse ourselves in our surroundings we can have more meaningful experiences. Surprisingly, <a href="https://www.sciencedirect.com/science/article/pii/S0261517724000487">even luxury travel</a> – often dismissed as wasteful – can encourage respect and mindfulness for those who invest financially and mentally in their journey, unlike cheaper, mainstream tourism. Activities such as “<a href="https://www.sciencedirect.com/science/article/pii/S2666957921000197">forest bathing</a>”, <a href="https://www.visitutah.com/articles/mindful-hiking">hiking</a> or engaging with <a href="https://www.outofyourcomfortzone.net/a-guide-to-slow-travel-immersing-yourself-in-local-cultures/">local cultures</a> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6723984/">boost wellbeing and meaning</a>, going beyond just “taking a photo for likes”. This mindful approach can <a href="https://www.sciencedirect.com/science/article/pii/S0160738321001419">change our behaviour on a personal level</a>. By focusing attention on fewer experiences, <a href="https://www.tandfonline.com/doi/full/10.1080/00913367.2024.2325144">travellers can heighten</a> their sense of awe and appreciation, making the travel more memorable. This idea is evident in “<a href="https://journals.sagepub.com/doi/abs/10.1177/002216786200200102?casa_token=PrIQTkCMjx0AAAAA:wtswfg0cuEuQec0zVg-Mbf9MuXYoqhQkWbaQCGdjxWkYUpVOwBu8Op5jC6V4nOghnow3xpwN3fDn">peak experiences</a>”. Disney, for example, creates <a href="https://ideaexchange.uakron.edu/docam/vol9/iss2/6/">emotionally-charged moments</a> that stick in visitors’ minds. Other experiences, such as “<a href="https://journals.sagepub.com/doi/full/10.1177/14614448211072808">digital detoxes</a>” or <a href="https://academic.oup.com/jcr/article-abstract/45/6/1142/4999270">pilgrimages</a> can leave a contemplative impression.

Rare coin hidden for decades to fetch eye-watering sum

Three sisters from the US who inherited a dime coin kept it in a bank vault for more than 40 years, and while they know it had some value, they didn't know just how much until a few years ago. The rare coin, struck by the US Mint in San Francisco in 1975, could be worth more than $US500,000 ($748,000), according to Ian Russell, president of GreatCollections, the auction house selling the coin. What makes the coin depicting President Franklin D. Roosevelt so valuable is that it is just one of two coins missing the "S" mint mark for San Francisco. The other dime sold for $US682,000 (over $1 million) at a 2019 auction and then again months later to a private collector. While avid coin collectors have known about the existence of these two extraordinarily rare coins, their whereabouts had remained a mystery since the late 1970s. “They were hidden for decades,” Russell said. “Most major collectors and dealers have never seen one.” The three sisters from Ohio, who want to remain anonymous, inherited one of the two dimes after the recent death of their of their brother, Russell said. They told Russell that their brother and mother bought the first error coin discovered in 1978 for $27,225, which would amount to roughly $135,000 today. Their parents, who ran a dairy farm, saw the coin as a financial safety net, and it was only until last year that one of the sisters saw the coin first-hand. Russell also said that their brother had reached out to him about seven years ago and told him about the coin, but he too kept it a secret. When Russell told one of the sisters about the potential value of the coin, she told him: “is that really possible?”. The coin, known as the “1975 ‘no S’ proof dime,” will be displayed at a coin show beginning on Wednesday in Tampa, Florida, and before <a href="https://www.greatcollections.com/Coin/1655587" target="_blank" rel="noopener">the auction</a> closes late next month, Russell said. The current highest bidder has offered $US250,000 ($374,000). Images: Great Collections/ Professional Coin Grading Services

Is still water better for you than sparkling water?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/christian-moro-121754">Christian Moro</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/charlotte-phelps-1187658">Charlotte Phelps</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Still or sparkling? It’s a question you’ll commonly hear in a café or restaurant and you probably have a preference. But is there any difference for your health? If you love the fizz, here’s why you don’t have to pass on the sparkling water. <h2>What makes my water sparkle?</h2> This article specifically focuses on comparing still filtered water to carbonated filtered water (called “sparkling water” or “unflavoured seltzer”). Soda water, mineral water, tonic water and flavoured water are similar, but not the same product. The bubbles in sparkling water are created by adding carbon dioxide to filtered water. It reacts to produce carbonic acid, which makes sparkling water more acidic (a pH of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5747581/">about 3.5</a>) than still (closer to neutral, with a pH around 6.5-8.5). <h2>Which drink is healthiest?</h2> Water is the best way to hydrate our bodies. Research shows when it comes to <a href="https://pubmed.ncbi.nlm.nih.gov/26702122/">hydration</a>, still and sparkling water are <a href="https://www.jstage.jst.go.jp/article/jnsv/58/5/58_333/_article">equally effective</a>. Some people believe water is healthier when it comes from a sealed bottle. But in Australia, tap water is <a href="https://www.waterquality.gov.au/guidelines/drinking-water">monitored very carefully</a>. Unlike bottled water, it also has the added benefit of fluoride, which can help protect young children against <a href="https://linkinghub.elsevier.com/retrieve/pii/S0002-8177(14)60225-7">tooth decay</a> and cavities. Sparkling or still water is always <a href="https://pubmed.ncbi.nlm.nih.gov/30354445/">better</a> than artificially sweetened flavoured drinks or juices. <h2>Isn’t soda water bad for my teeth and bones?</h2> There’s no evidence sparkling water damages your bones. While drinking a lot of soft drinks is linked to increased <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7071508/">fractures</a>, this is largely due to their association with higher rates of obesity. Sparkling water is more acidic than still water, and acidity can soften the teeth’s <a href="https://pubmed.ncbi.nlm.nih.gov/35635779/">enamel</a>. Usually this is not something to be too worried about, unless it is mixed with sugar or citrus, which has much higher levels of acidity and can harm teeth. However, if you grind your teeth often, the softening could enhance the <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/teeth-grinding#risk-factors-for-tooth-grinding">damage it causes</a>. If you’re undertaking a home whitening process, sparkling water <a href="https://pubmed.ncbi.nlm.nih.gov/39123328/">might discolour</a> your teeth. In most other cases, it would take a lot of sparkling water to pass by the teeth, for a long period of time, to cause any noticeable damage. <h2>How does drinking water affect digestion?</h2> There is a <a href="https://www.mayoclinic.org/healthy-lifestyle/nutrition-and-healthy-eating/expert-answers/digestion/faq-20058348">misconception</a> drinking water (of any kind) with a meal is bad for digestion. While theoretically water could dilute stomach acid (which breaks down food), the practice of drinking it doesn’t appear <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11045127/">to have any negative effect</a>. Your digestive system simply adapts to the consistency of the meal. Some people do find that carbonated beverages cause some stomach upset. This is due to the build-up of <a href="https://www.sciencedirect.com/science/article/pii/S0939475309000787">gases</a>, which can cause bloating, cramping and discomfort. For people with an <a href="https://www.nature.com/articles/s41598-023-44916-8">overactive bladder</a>, the acidity might also aggravate the <a href="https://journals.physiology.org/doi/full/10.1152/ajpcell.00441.2022">urinary</a> system. Interestingly, the fizzy “<a href="https://pubmed.ncbi.nlm.nih.gov/34399552/">buzz</a>” you feel in your mouth from sparkling water fades the more you drink it. <h2>Is cold water harder to digest?</h2> You’ve chosen still or sparkling water. What about its temperature? There are surprisingly few studies about the effect of drinking cold water compared to room temperature. There is some evidence colder water (at two degrees Celsius) might inhibit <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7000532/">gastric contractions</a> and slow down digestion. Ice water may constrict blood vessels and cause <a href="https://www.sciencedirect.com/science/article/abs/pii/0306362383900642">cramping</a>. However other research suggests drinking cold water might temporarily boost <a href="https://academic.oup.com/jcem/article/88/12/6015/2661518">metabolism</a>, as the body needs to expend energy to warm it up to body temperature. This effect is minimal and unlikely to lead to significant <a href="https://academic.oup.com/jcem/article/91/9/3598/2656772">weight loss</a>. <h2>Which water wins?</h2> The bottom line is water is essential, hydrates us and has countless other <a href="https://news.com.au/lifestyle/health/diet/fewer-than-25-per-cent-simple-question-most-aussies-cant-answer/news-story/04693f23f03d9e8b6483cf34b47d9fcb">health benefits</a>. Water, with carbonated bubbles or without, will always be the healthiest drink to choose. And if you’re concerned about any impact to teeth enamel, one trick is to follow sparkling water with a glass of still. This helps rinse the teeth and return your mouth’s acidity back to normal.<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/237125/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/christian-moro-121754">Christian Moro</a>, Associate Professor of Science & Medicine, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/charlotte-phelps-1187658">Charlotte Phelps</a>, Senior Teaching Fellow, Medical Program, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

38-year-old message in a bottle washes up on beach

A message in a bottle written almost 40 years ago has been discovered by a four-year-old at a beach in Perth. Meg Prideaux took her son Leo, 4, “looking for treasure” at the beach in their hometown of Lancelin, when he spotted the bottle with a rolled-up note inside. “We brought it home and we waited for my daughter and my husband to come home, but we couldn’t get it open,” she said. “There was a bit of corrosion and a few barnacles had started to grow, so it had been there for a while.” After a bit of trouble, they got the bottle open and unfurled the soggy, but still legible, letter and found it dated from 1985. The message had been written 39 years ago by then-teenagers Joanne Hunter and Louise Pocock, who were 15 when they wrote the note while on holiday. Their note came with a simple request — that anyone who finds the bottle send a return letter to the girls in suburban Perth. With the help of <a href="https://7news.com.au/news/message-in-a-bottle-thrown-into-sea-in-1985-washes-up-on-wa-beach-c-15876207" target="_blank" rel="noopener">7News</a>, Meg and Leo Prideaux were able to track down Joanne Hunter, who is now Joanne Evans and aged 54. “I was like, ‘Oh my god. Is that really that?’ I haven’t thought about that in forever,” Evans said. “We wrote it at night and sealed it with wax and then we actually swam it out into the water because, at first, we threw it from the beach and it kept washing back in, so we swam out the next morning." “My family had a beach house directly across the road and Louise came with my family for the school holidays. She was always full of excitement and had such a great imagination, it was her idea to do it.” Pocock died of leukaemia six years ago but her sister, Sarah Martin, said she would have enjoyed “such a kick” knowing the message had been found. “Oh, she’d be so happy, she really would — especially that a little boy found it as well after 39 years just sitting in the sand,” Martin said. “She was a really great, fun, happy-go-lucky sort of person and really did well in her life, very artistic and creative, and she met a wonderful man and married him and had a beautiful little girl. “As time goes on, you feel like they’re slipping further away from you and then this message is such a wonderful thing that just came out of the blue.” The Prideaux family now plan to meet Evans to return the bottle and the message to its original author some time in the near future.

Manhunt after stranger pours scalding hot coffee on baby in public park

Queensland Police have released footage of the man they believe burned a baby with a scalding hot drink in a public park. On Wednesday, the unknown man approached the family at Hanlon Park in Brisbane and poured hot coffee on the nine-month-old baby boy. He was rushed to the Queensland Children’s Hospital with burns to his face, upper body and arms, with the burns covering 60 per cent of his body. Queensland Police have now released CCTV footage from the area, showing a man running from the park. He appears approximately 30 to 40 years old, with a proportionate build and tanned skin, and was wearing a black hat, glasses, a shirt and shorts. Anyone who recognises the man has been urged to contact the police with information. An off-duty nurse heard the commotion in the park from the balcony of her apartment, telling <a href="https://7news.com.au/news/footage-of-man-who-burnt-baby-with-hot-drink-at-hanlon-park-in-stones-corner-released-c-15856522" target="_blank" rel="noopener">7News</a> she went outside to investigate when she heard screaming. She said she heard the child’s mother yelling “my baby, my baby”. The nurse rushed down to the park to help the boy, taking him to her nearby apartment where he was placed under a cold shower before paramedics arrived. Locals told 7News the attack was “terrible” and they were shocked it had happened in their community. “It’s really scary when you think that we haven’t got a community that looks after our young and vulnerable,” one woman said.

The eye-watering salaries of The Voice Australia judges revealed

The Voice Australia has revamped the lineup of the judges for the 2024 season, with American music icons Adam Lambert and LeAnn Rimes joining Aussies Guy Sebastian and Kate Miller-Heidke. As the new American talent joins the show, Seven are reportedly paying big buck for the international stars after their salaries were leaked by <a href="https://au.lifestyle.yahoo.com/exclusive-the-voice-australia-coaches-salaries-leaked-amid-pay-row-230921307.html" target="_blank" rel="noopener">Yahoo News</a>. According to the publication, an alleged source claims that Adam and LeAnn "are believed to be receiving between $750,000 and $1.2 million" for the single season of the show. Meanwhile, Kate Miller-Heidke "is believed to be receiving upwards of $500,000" for her first season on the show. Veteran judge Guy Sebastian allegedly started on $750,000 per season in 2019, "but this is believed to now be worth $1 million". These new judges are getting "considerably less" than outgoing coaches Rita Ora and Jason Derulo, Yahoo alleges. According to a production insider, the reason for the switch-up of judges was the star's pay cheques, and a desire from producers to keep costs down. The insider said the program has been wanting a change in judges lineup for a quite some time, adding that salary increases are necessary to keep returning stars on the show and the price tag for the former crop was "too expensive". "The company line was that Jessica, Rita and Jason were all too busy, but I don't think anyone is too busy to pick up these sorts of pay cheques. It certainly did have a lot to do with keeping the costs down." Image credits: Seven

The eye-watering cost of Karl Stefanovic's "highly secret" 50th birthday bash

Karl Stefanovic had a "highly secretive" birthday party in Saint-Tropez. France, according to Women's Day. The Today host, who was in Paris to cover the Olympic games earlier this month, reportedly booked out an entire hotel for his 50th birthday bash. A source claimed that his party cost a staggering $200,000, with A-listers James Packer and Anthony Bell among the guests. "He'd be thinking you only turn 50 once so let's do this properly and go big!" the insider claimed. "Much like the $50,000 he dropped for (wife) Jasmine's 40th earlier this year, and the rumoured $10,000 birthday parties they have hosted for their four-year-old daughter Harper," they continued. "And then there was their $700,000 lavish Mexican nuptials - Karl has never done anything half-baked!" The party was allegedly 1970s themed, with Stefanovic's wife also showing off her new designer dresses. This comes after it was initially reported that Stefanovic was set to cancel his planned 50th birthday bash in Paris. Earlier this year, the Today host was reported to have spent a whopping $50,000 on his wife's lavish birthday celebrations in Noosa, according to the publication. Jasmine's entire look alone was worth an eye-watering $5,575, with her gown from Zimmermann costing $1,950. The party reportedly lasted for about two days, with a "recovery shindig" allegedly worth $10,000 also taking place. A close friend of the couple said at the time that "Karl is an old romantic" and was more than happy to treat his wife to a lavish birthday. Images: Instagram

40°C in August? A climate expert explains why Australia is ridiculously hot right now

<div class="theconversation-article-body"><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> It’s winter in Australia, but as you’ve probably noticed, the weather is unusually warm. The top temperatures over large parts of the country this weekend were well above average for this time of year. The outback town of Oodnadatta in South Australia recorded 38.5°C on Friday and 39.4°C on Saturday – about 16°C above average. Both days were well above the state’s previous winter temperature record. In large parts of Australia, the heat is expected to persist into the coming week. A high pressure system is bringing this unusual heat – and it’s hanging around. So temperature records have already fallen and may continue to be broken for some towns in the next few days. It’s no secret the world is warming. In fact, 2024 is shaping up to be <a href="https://www.carbonbrief.org/state-of-the-climate-2024-now-very-likely-to-be-warmest-year-on-record/">the hottest year on record</a>. Climate change is upon us. Historical averages are becoming just that: a thing of the past. That’s why this winter heat is concerning. The warming trend will continue for at least as long as we keep burning fossil fuels and polluting the atmosphere. Remember, this is only August. The heatwaves of spring and summer are only going to be hotter. <figure><iframe src="https://www.youtube.com/embed/GmhMKjxEGQo?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Widespread heat forecast for Australia in August, 2024 (Bureau of Meteorology)</figcaption></figure> <h2>Records broken across Australia</h2> The Bureau of Meteorology was expecting many records to be broken over the weekend across several states. On Thursday, bureau meteorologist Angus Hines described: <blockquote> A scorching end to winter, with widespread heat around the country in coming days, including the chance of winter records across multiple states for maximum temperature. </blockquote> The amount of heat plunging into central Australia was particularly unusual, Hines said. On Friday, temperatures across northern South Australia and southern parts of the Northern Territory were as much as 15°C above average. Temperatures continued to soar across northern parts of Western Australia over the weekend, with over 40°C recorded at Fitzroy Crossing on Sunday. It has been 2–12°C above average from Townsville all the way down to Melbourne for several days in a row. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&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/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=412&fit=crop&dpr=1 600w, https://images.theconversation.com/files/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=412&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=412&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=518&fit=crop&dpr=1 754w, https://images.theconversation.com/files/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=518&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=518&fit=crop&dpr=3 2262w" alt="Animated maximum temperature anomaly map showing heat building across central Australia" /></a><figcaption>Maximum temperature anomalies from August 19-24, showing heat building across Australia. Bureau of Meteorology, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> Bear in mind, it’s only August. As Hines said, the fire weather season hasn’t yet hit most of Australia – but the current conditions – hot, dry and sometimes windy – are bringing moderate to high fire danger across Australia. It may also bring dusty conditions to central Australia. And for latitudes north of Sydney and Perth, most of the coming week will be warm. <h2>What’s causing the winter warmth?</h2> <a href="http://www.bom.gov.au/australia/charts/synoptic_col.shtml">In recent days</a> a stubborn high pressure system has sat over eastern Australia and the Tasman Sea. It has kept skies clear over much of the continent and brought northerly winds over many areas, transporting warm air to the south. High pressure promotes warm weather – both through clearer skies that bring more sunshine, and by promoting the descent of air which <a href="https://media.bom.gov.au/social/blog/2544/explainer-what-influences-air-temperature/">causes heating</a>. By late August, both the intensity of the sun and the length of the day has increased. So the centre of Australia can really warm up when under the right conditions. High pressure in June can be associated with cooler conditions, because more heat is lost from the surface during those long winter nights. But that’s already less of an issue by late August. This kind of weather setup has occurred in the past. Late-winter or early-spring heat does sometimes occur in Australia. However, this warm spell is exceptional, as highlighted by the broken temperature records across the country. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&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/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=450&fit=crop&dpr=1 600w, https://images.theconversation.com/files/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=450&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=450&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=566&fit=crop&dpr=1 754w, https://images.theconversation.com/files/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=566&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=566&fit=crop&dpr=3 2262w" alt="Graph of August Australian-average temperatures increasing since 1910" /></a><figcaption>August temperatures have been rising over the past century.

Australia’s three warmest Augusts on record have all occurred since 2000 – and <a href="https://theconversation.com/why-is-australia-having-such-a-warm-winter-a-climate-expert-explains-210693">last August was the second-warmest since 1910</a>. When the right weather conditions occur for winter warmth across Australia, the temperatures are higher than a century ago. The warmth we are experiencing now comes off the back of <a href="https://theconversation.com/earth-has-just-ended-a-13-month-streak-of-record-heat-heres-what-to-expect-next-236655">a recent run of global temperature records</a> and <a href="https://theconversation.com/extreme-heat-is-breaking-global-records-why-this-isnt-just-summer-and-what-climate-change-has-to-do-with-it-234249">extreme heat events across the Northern Hemisphere</a>. This warm spell is set to continue, with temperatures above 30°C forecast from Wednesday through to Sunday in Brisbane. The outlook for spring points to continued <a href="http://www.bom.gov.au/climate/outlooks/#/temperature/maximum/median/seasonal/0">above-normal temperatures</a> across the continent, but as always we will likely see both warm and cold spells at times. Such winter warmth is exceptional and already breaking records. Climate change is already increasing the frequency and intensity of this kind of winter heat – and future warm spells will be hotter still, if humanity’s greenhouse gas emissions continue.<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/237398/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: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
