“Splendour in the Mud”:
Climate breakdown and car dependency put an end to commercial drive-in music activities

A “report found 85% of festivalgoers had been affected by either floods, storms, heatwaves or the threat of bushfires at an event they had attended in the past 12 months.”

The “Splendour in the Mud” festival left tens of thousands of motorists bogged and stranded in torrential rain. Extreme heat from greenhouse gas emission is also eliminating the ‘drive-in’ model for outdoor mass gatherings.

Unexplained #HeatWave ‘#Hotspots’ Are Popping Up Across the Globe

"Earth’s hottest recorded year was 2023, at 2.12 degrees F above the 20th-century average. This surpassed the previous record set in 2016. So far, the 10 hottest yearly average temperatures have occurred in the past decade. And, with the hottest summer and hottest single day, 2024 is on track to set yet another record.

"All this may not be breaking news to everyone, but amid this upward march in average temperatures, a striking new phenomenon is emerging: distinct regions are seeing repeated heat waves that are so extreme, they fall far beyond what any model of global warming can predict or explain. A new study provides the first worldwide map of such regions, which show up on every continent except Antarctica like giant, angry skin blotches. In recent years these heat waves have killed tens of thousands of people, withered crops and forests, and sparked devastating wildfires.

"'The large and unexpected margins by which recent regional-scale extremes have broken earlier records have raised questions about the degree to which climate models can provide adequate estimates of relations between global mean temperature changes and regional climate risks,' says the study.

"'This is about extreme trends that are the outcome of physical interactions we might not completely understand,' said lead author Kai Kornhuber, an adjunct scientist at the Columbia Climate School’s Lamont-Doherty Earth Observatory. 'These regions become temporary hothouses.' Kornhuber is also a senior research scholar at the International Institute for Applied Systems Analysis in Austria.

"The study was just published in the journal Proceedings of the National Academy of Sciences."

"The study looks at heat waves over the past 65 years, identifying areas where extreme heat is accelerating considerably faster than more moderate temperatures. This often results in maximum temperatures that have been repeatedly broken by outsize, sometimes astonishing, amounts. For instance, a nine-day wave that hammered the U.S. Pacific Northwest and southwestern Canada in June 2021 broke daily records in some locales by 30 degrees C, or 54 F. This included the highest ever temperature recorded in Canada, 121.3 F, in Lytton, British Columbia. The town burned to the ground the next day in a wildfire driven in large part by the drying of vegetation in the extraordinary heat. In Oregon and Washington state, hundreds of people died from heat stroke and other health conditions.

"These extreme heat waves have been hitting predominantly in the last five years or so, though some occurred in the early 2000s or before. The most hard-hit regions include populous central China, Japan, Korea, the Arabian peninsula, eastern Australia and scattered parts of Africa. Others include Canada’s Northwest Territories and its High Arctic islands, northern Greenland, the southern end of South America and scattered patches of Siberia. Areas of Texas and New Mexico appear on the map, though they are not at the most extreme end.

"According to the report, the most intense and consistent signal comes from northwestern Europe, where sequences of heat waves contributed to some 60,000 deaths in 2022 and 47,000 deaths in 2023. These occurred across Germany, France, the United Kingdom, the Netherlands and other countries. Here, in recent years, the hottest days of the year are warming twice as fast the summer mean temperatures. The region is especially vulnerable in part because, unlike places like the United States, few people have air conditioning, because traditionally it was almost never needed. The outbreaks have continued. In September, new maximum temperature records were set in Austria, France, Hungary, Slovenia, Norway and Sweden. Well into October, many parts of the U.S. Southwest and California saw record temperatures for the month more typical of midsummer.

"The researchers call the statistical trends 'tail-widening'―that is, the anomalous occurrence of temperatures at the far upper end, or beyond, anything that would be expected with simple upward shifts in mean summer temperatures. But the phenomenon is not happening everywhere; the study shows that maximum temperatures across many other regions are actually lower than what models would predict. These include wide areas of the north-central United States and south-central Canada, interior parts of South America, much of Siberia, northern Africa and northern Australia. Heat is increasing in these regions as well, but the extremes are increasing at similar or lower speed than what changes in average would suggest.

"Climbing overall temperatures make heat waves more likely in many cases, but the causes of the extreme heat outbreaks are not entirely clear. In Europe and Russia, an earlier study led by Kornhuber blamed heat waves and droughts on wobbles in the jet stream, a fast-moving river of air that continuously circles the northern hemisphere. Hemmed in by historically frigid temperatures in the far north and much warmer ones further south, the jet stream generally confines itself to a narrow band. But the Arctic is warming on average far more quickly than most other parts of the Earth, and this appears to be destabilizing the jet stream, causing it to develop so-called Rossby waves, which suck hot air from the south and park it in temperate regions that normally do not see extreme heat for days or weeks at a time."

The impacts of extreme heat events on wildlife
How koalas are trying to cope

Temperatures are predicted to swelter above 40 degrees today in NSW. People are retreating into their coal-fired AC houses and AC combustion boxes. Dogs are offered drinking bowls at almost every door in Bellingen, but Australian animals are out there in a degraded landscape having to deal with the extreme heat we generate.

Koalas are "using a tree species they don't feed on ... [hugging] the main trunks of trees and lower to the ground. We came up with the idea they were losing heat to the tree trunks. I found a colleague with a fancy thermal camera and went out in hot weather and it's exactly what they were doing. By pressing their body into the coolest tree they could find, the koalas halved their need to drink water in heatwaves. Hugging trees may not be enough for koalas to maintain their already dwindling distribution with rising average temperatures."

Deforestation has big impact on regional temperatures

"...Deforestation causes warming at distances up to 60 miles away. The greater the forest clearance, the higher the temperature. This is in addition to the wider climate impact of global heating."

“We show that regional forest loss increases warming by more than a factor of four with serious consequences for the remaining Amazon forest and the people living there.”

“More and more, we are demonstrating the big benefits the forests bring to surrounding regions. For farmers, they bring cooler air and more rainfall. Until now, studies on the impact of forest clearance on heat have concentrated on local effects with a clear correlation between loss of tree cover and higher temperatures in the area where the trees were cut down. The new research went further by looking at whether there is also a warming effect over a wider area." >
