A remote town in Western Australia has equalled the country’s hottest day on record, reporting a scorching 50.7 degrees Celsius (123.26 degrees Fahrenheit), the Bureau of Meteorology said. Such temperatures could become commonplace in Australia due to global warming, the country’s Climate Council warned. The coastal town of Onslow hit the blistering high on Thursday afternoon. “NEW Western Australian maximum temperature record and equal National temperature record!” the state’s Bureau of Meteorology posted on Twitter. “Onslow reached an unprecedented – 50.7C which is a WA record and equals Australia’s hottest day set 62 years ago in Oodnadatta SA.” The country last recorded a temperature of 50.7C on January 2, 1960 at South Australia’s Oodnadatta Airport, according to the bureau’s website. Climate Council research director Dr Martin Rice said the record was “part of a long-term warming trend driven by the burning of coal, oil and gas”. He said extreme temperatures were already having “deadly catastrophic consequences” in Australia. “Heatwaves are the silent killer in Australia, they cause more deaths than any other extreme weather events,” he said. Australia has experienced a summer with bushfires in the country’s west and deadly flooding on its eastern coast. Rice said that, without a reduction in greenhouse gas emissions, such record temperatures could become commonplace in Australia. “In Sydney and Melbourne, we will see 50-degree summer days by 2030,” he said. The Bureau of Meteorology is expected to confirm the record officially on Friday afternoon after quality control checks are completed. Last nine years all among 10 hottest-ever, says US The nine years spanning 2013-2021 all rank among the 10 hottest on record, according to an annual report a US agency released Thursday, the latest data underscoring the global climate crisis. For 2021, the average temperature across global surfaces was 1.51 degrees Fahrenheit (0.84 degrees Celsius) above the 20th-century average, making the year the sixth-hottest in the overall record, which goes back to 1880. “Of course, all this is driven by increasing concentrations of heat trapping gases like carbon dioxide,” Russell Vose, a senior climatologist for the National Oceanic and Atmospheric Administration (NOAA) told reporters. “There’s probably a 99 percent chance that 2022 will rank in the top 10, a 50-50 chance, maybe a little less, it’ll rank in the top five, and a 10 percent chance it’ll rank first” barring an unforeseen event like a major volcanic eruption or a large comet hitting Earth, he said. NOAA uses the 21-year span from 1880 to 1900 as a surrogate to assess pre-industrial conditions, and found the 2021 global land and ocean temperature was 1.87F (1.04C) above the average. A separate analysis of global temperature released by NASA had 2021 tying with 2018 as the sixth-warmest on record. Both data sets vary very slightly from the European Union’s Copernicus Climate Change Service in their assessment, which had 2021 as the fifth warmest in records tracking back to the mid-19th century. But the overall convergence of trends increases scientists’ confidence in their conclusions. Increases in abundance of atmospheric greenhouse gases since the industrial revolution are mainly the result of human activity and are largely responsible for the observed increases. Climate scientists say it is crucial to hold end-of-century warming to within a 1.5C (2.7F) rise to avert the worst impacts — from mega-storms to mass die-offs in coral reefs and the decimation of coastal communities. At the present rate of heating, the planet might hit 1.5C in the 2030s. “But it’s not the case that at 1.4 everything is hunky dory and at 1.6 all hell has broken loose,” said NASA climate expert Gavin Schmidt. The impacts have been increasingly felt in recent years — including record-shattering wildfires across Australia and Siberia, a once-in-1,000-years heatwave in North America and extreme rainfall that caused massive flooding in Asia, Africa, the US and Europe. Last year also saw nearly 700 people die in the contiguous United States due to extreme weather events, such as Hurricane Ida, and a maximum temperature in Sicily of nearly 120F, a European record if verified. – Arctic amplification – The heat records observed in 2021 came despite the year beginning in a cold phase thanks to an El Nino Southern Oscillation (ENSO) episode across the central and eastern tropical Pacific Ocean. Heating might have also been partly offset by the resumption of activities that created heat-reflecting aerosols, which were lower during the Covid related lockdowns of 2020, said Schmidt. The Northern Hemisphere land surface temperature was the third-highest on record. The 2021 Southern Hemisphere surface temperature was the ninth highest on record. Land heat records were broken in parts of northern Africa, southern Asia, and southern South America in 2021, while record-high sea surface temperatures were observed across parts of the Atlantic and Pacific oceans. There were no cold records broken for land or ocean areas. Average annual Northern Hemisphere snow cover was 9.3 million square miles (24.3 million square kilometers), the seventh-smallest annual snow cover extent in the 1967-2021 record. Meanwhile, with the exception of September and December, each month of 2021 had Arctic sea ice levels in the top-10 lowest levels for those respective months. Overall, the Arctic is heating around three times faster than the global average — adding to sea level rises and the release of more carbon dioxide and methane from the permafrost, an effect known as “Arctic amplification.”
