Australia experiences record-setting, summer-like heat even though winter is coming

It’s autumn in Australia , but you might not be able to tell from the weather . Record-breaking heat has gripped large swaths of the country — the government’s Bureau of Meteorology said Sydney, Adelaide, and other locations have hit the “hottest or equal-hottest April days on record.” We have published a Special Climate Statement exploring the highly unseasonal hot spell experienced by much of Australia at the start of April. More at https://t.co/jHCzg7hb3c pic.twitter.com/Yg2uQHeOqj — Bureau of Meteorology, Australia (@BOM_au) April 13, 2018 Persistent heat in Australia prompted the Bureau of Meteorology to release a Special Climate Statement : a 22-page document delving into detail about record-setting temperatures across the country. In a media release about the climate statement, the Bureau of Meteorology said during the first week of April, the heat affected primarily northwest Australia. Then the hot spell moved southeast, impacting New South Wales, Victoria, and South Australia. All those states set April temperature records. Related: Rise of just 0.5 degrees C in India has already resulted in deadly heat Bureau of Meteorology climatologist Blair Trewin said the heat’s extent was exceptional, saying in the statement, “The heat had been building up in northwestern Australia since monsoon rains ended in mid-March. Northwesterly winds then brought the hot air mass southeast at the start of this week, which is when we saw the impacts on South Australia, Victoria, and New South Wales.” The climate statement described conditions as as abnormally warm, and said the heat was more in line with what a person might expect in mid-summer, not mid-autumn. The statement said the heat “was unprecedented in many areas in April for its intensity, its persistence, or both.” Is climate change responsible for the heat? The Bureau of Meteorology didn’t say, in the statement or the media release. The climate statement pointed back to past notable April heat events in southeastern Australia, which occurred in 1922, 1938, 1986, and 2005. But the heat could be a preview of coming attractions, according to Mashable , which said extreme events such as this one could be more regular in a world impacted by climate change. + Special Climate Statement 65 — persistent summer-like heat sets many April records + Bureau of Meteorology Media Release Via Mashable Images via Depositphotos ( 1 , 2 )

Ocean heatwaves have risen by more than 50% since 1925

Oceanic heatwaves have increased by 54 percent since 1925, posing a major threat to aquatic ecosystems . In a study published in the journal Nature Communications , researchers outlined the cause and effects of underwater heatwaves and their future impact on the world’s oceans. According to researchers, “These trends can largely be explained by increases in mean ocean temperatures, suggesting that we can expect further increases in marine heatwave days under continued global warming.” As higher levels of greenhouse gases concentrate in the atmosphere, greater amounts of solar radiation are trapped on Earth — 95 percent of which is absorbed by the ocean . Much like the relationship between extreme weather and rising temperatures on land, as the mean average oceanic temperature rises, so too does the likelihood of extreme oceanic heating events. Because water is able to hold more heat than land, these extreme temperature events last longer than those caused by higher air temperatures. A recent example occurred in 2015, when ocean temperatures from Mexico to Alaska increased up to 10 degrees above average. Fifty documented whale deaths were recorded in this period, and many other marine animals suffered from the unusually hot water. Related: Researchers discover a completely new ocean zone swimming with new species To conduct the study, the research team gathered and analyzed data on sea surface temperatures from the past century, with recent decades producing the most accurate data. Given that the most useful data is from such a short time period, the team could not explicitly draw a causal link between anthropogenic climate change and oceanic heatwaves. They explained that the fluctuations may be due to natural temperature swings. Nonetheless, the researchers concluded that the notable increase in average oceanic temperature is absolutely affected by climate change . The scientists are most concerned that — in combination with other pressures such as acidification, overfishing , and pollution — fragile ecosystems could reach a tipping point by oceanic heatwaves and ultimately collapse.

Why Many Americans May Flee to Alaska in the Coming Decades

Comments Off on Why Many Americans May Flee to Alaska in the Coming Decades

Job opportunity, the cool factor and affordability may no longer be the major reason Americans move. Instead, climate change may force people to flee certain regions into cities that can maintain cooler temperatures and ward off rising sea levels. Scientists predict that most of California and the Southwest, along with the East Coast and Southeast will be disaster zones in a few decades due to drought, wildfires, heat waves, hurricanes and rising sea levels. But the Pacific Northwest, the northern Great Plains and the Midwest are predicted to fair much better as global warming heats up.

Terrifying UN Report Warns Climate Change is Becoming Irreversible

Comments Off on Terrifying UN Report Warns Climate Change is Becoming Irreversible

The Intergovernmental Panel on Climate Change (IPCC) just released an alarming new report that shows unchecked greenhouse gas emissions are leading to inevitable and irreversible climate change. The report warns that higher seas , devastating heat waves , torrential rain and other climate extremes are likely to intensify unless greenhouse gases are brought under control. And furthermore, the report warns that the world is nearing the temperature at which the loss of the vast Greenland ice sheet is inevitable.

Monarch Butterfly Numbers Drop To Lowest Recorded Level

Comments Off on Monarch Butterfly Numbers Drop To Lowest Recorded Level

Scientists say the number of Monarch butterflies wintering in Mexico is now at the lowest level ever  since records began in 1993. In their recorded peak in 1995, the butterflies covered more than 44.5 acres of fir and pine forests. This year, researchers were only able to find butterflies across 1.65 acres of land — a mere 56% of last year’s numbers . After three years in steep decline, it’s becoming obvious that this is a long-term trend and not merely a temporary or seasonal dip.

The Climatic Data Center at the National Oceanic and Atmospheric Association has released a new analysis of 12 extreme weather events in 2012, and the findings aren’t reassuring . Researchers discovered that sea-level rise caused by climate change has made extreme flooding along the East Coast twice as likely now as it was in 1950.
