Instead of making a new thread time, use this thread for posting news articles. Climate crisis: 2020 was joint hottest year ever recorded >Despite a 7% fall in fossil fuel burning due to coronavirus lockdowns, heat-trapping carbon dioxide continued to build up in the atmosphere, also setting a new record. The average surface temperature across the planet in 2020 was 1.25C higher than in the pre-industrial period of 1850-1900, dangerously close to the 1.5C target set by the world’s nations to avoid the worst impacts. >Only 2016 matched the heat in 2020, but that year saw a natural El Niño climate event which boosts temperatures. Without that it is likely 2020 would have been the outright hottest year. Scientists have warned that without urgent action the future for many millions of people “looks black”. >The temperature data released by the European Union’s Copernicus Climate Change Service (C3S) showed that the past six years have been the hottest six on record. They also showed that Europe saw its hottest year on record, 1.6C above the long-term average, with a searing heatwave hitting western Europe in late July and early August. >The Arctic and northern Siberia saw particularly extreme average temperatures in 2020, with a large region 3C higher than the long-term average and some locations more than 6C higher. This resulted in extensive wildfires, with a record 244m tonnes of CO2 released within the Arctic Circle. Arctic sea ice was also significantly lower, with July and October seeing the smallest extent on record for those months. >The UK Met Office issued a forecast on Friday that CO2 levels will pass a new milestone in 2021 – being 50% higher than before the Industrial Revolution. Its scientists said CO2 will exceed 417 parts per million (ppm) for several weeks from April to June, which is 50% higher than the 278 ppm in the late 18th century when industrial activity began. >“The human-caused buildup of CO2 in the atmosphere is accelerating,” said Prof Richard Betts at the Met Office. “It took over 200 years for levels to increase by 25%, but now just over 30 years later we are approaching a 50% increase. Global emissions will need to be brought down to net zero within about the next 30 years if global warming is to be limited to 1.5C.” https://archive.vn/nFTkl https://www.theguardian.com/environment/2021/jan/08/climate-crisis-experts-2020-joint-hottest-year-ever-recorded

Snow-Free Glaciers in Winter >Each January, the Himalayas are typically blanketed with fresh snow. But unusual winter melting in recent months has left several glaciers and mountains without a new coating. Many glaciers are bare even at their crest. >From October 2020 to January 2021, the average snow line—the boundary where snow-covered surfaces meet bare ground—on these glaciers rose around 100 meters (330 feet), indicating significant melt. >Melting season in the region around Mount Everest is usually concentrated during the summer monsoon (April to September). In the past year, however, abnormally warm temperatures have extended the melting period by four months. As of January 22, 2021, weather stations at Everest base camp reported maximum temperatures above freezing for eight days that month. On January 13, temperatures peaked at 7°C (45°F). >Due to less-than-normal seasonal snowfall, the warm temperatures are melting snow that was accumulated before the monsoon season. https://earthobservatory.nasa.gov/images/147840/snow-free-glaciers-in-winter https://archive.vn/dOvRs

U.S. had its coldest February in more than 30 years >Temperatures plunged to historic lows in some parts of the country last month, including nearly all of Texas, as an Arctic air mass gripped much of the nation. >Despite the chilly February, winter wrapped up warmer than normal, according to scientists at NOAA’s National Centers for Environmental Information. >The average temperature across the contiguous U.S. last month was 30.6 degrees F, 3.2 degrees below the 20th-century average, making it the 19th-coldest February in the 127-year record. It was also the coldest February since 1989. >Meteorological winter (December through February) was quite mild and dry across the contiguous U.S. The average temperature was 33.6 degrees F, 1.4 degrees above average, placing Winter 2021 in the warmest third of the winter record. Maine had its third-warmest winter; California had its 12th warmest. >Total precipitation this winter was 6.10 inches — 0.69 of an inch below average — which ranked among the driest one-third of winters in 126 years. North Dakota had its third-driest winter on record, while Virginia and Delaware had their ninth and 11th-wettest winters, respectively. >A brutally cold month for Texans: February 2021 brought the coldest air since December 1989 to much of the state. Several locations across central Texas — including Austin and Waco — broke records for the longest streak of below-freezing temperatures. Every county in Texas was under a Winter Storm Warning in mid-February and experienced wind chill values below zero as far south as the Rio Grande River and northeastern Mexico. >Alaska was colder than usual: Alaska saw its coldest February in 22 years. In Anchorage, the temperature never rose above 30 degrees F for the entire month, the first month since December 1998 with all daily high temperatures remaining below freezing. >Drought got a bit worse: According to the U.S. Drought Monitor report, 46.6% of the contiguous U.S. was in drought at the beginning of March, up slightly from 45.8% at the beginning of February. Drought expanded or intensified across portions of the northern and southern Plains, and Great Basin. https://www.noaa.gov/news/us-had-its-coldest-february-in-more-than-30-years https://archive.ph/g1Nz0

Japan’s cherry blossoms signal warmest climate in more than 1,000 years >But bloom dates have shifted radically earlier in recent decades, a sure sign that the region’s climate is warming and warming fast. >Yasuyuki Aono, a professor of environmental sciences at Osaka Prefecture University, has assembled a data set that compiles blossom-flowering dates in Kyoto all the way back to 800 A.D. It shows a sudden and remarkable change in the past 150 to 200 years. >But from 1850 to present day, the flowering has surged toward earlier dates at the rate of about one week per century. >Aono said the estimated temperature had warmed 6.1 degrees (3.4 Celsius) in Kyoto since 1820. >In his temperature reconstructions dating back as far as 800 A.D. posted online, no other period was as consistently warm as the present. >“But the large-scale warming of the past century is so distinct and widespread that it is increasingly evident from diverse records all around the globe.” >In both Kyoto and Washington, the warming trends and earlier blooms are most likely due to a growing urban heat island effect and increasing concentrations of greenhouse gases in the atmosphere. https://www.washingtonpost.com/news/capital-weather-gang/wp/2017/04/04/japans-cherry-blossoms-signal-warmest-climate-in-over-1000-years/ http://atmenv.envi.osakafu-u.ac.jp/aono/kyophenotemp4/ https://archive.vn/dClGJ https://archive.vn/Lxrfr
