“#Pandemic\u2019s cleaner air added heat to warming planet<\/strong>”
\n<\/p>\n

\n

Earth spiked a bit of a fever in 2020, partly because of cleaner air from the pandemic lockdown, a new study found.<\/p>\n

For a short time, temperatures in some places in the eastern United States, Russia and China were as much as half to two-thirds of a degree (.3 to .37 degrees Celsius) warmer. That\u2019s due to less soot and sulfate particles from car exhaust and burning coal, which normally cool the atmosphere temporarily by reflecting the sun\u2019s heat, Tuesday\u2019s study in the journal\u00a0Geophysical Research Letters\u00a0<\/a>reported.<\/p>\n

Overall, the planet was about .05 degrees (.03 degrees Celsius) warmer for the year because the air had fewer cooling aerosols, which unlike carbon dioxide is pollution you can see, the study found.<\/p>\n

\u201cCleaning up the air can actually warm the planet because that (soot and sulfate) pollution results in cooling\u201d which climate scientists have long known, said study lead author Andrew Gettelman, an atmospheric scientist at the National Center for Atmospheric Research. His calculations come from comparing 2020 weather to computer models that simulated a 2020 without the pollution reductions from pandemic lockdowns.<\/p>\n

This temporary warming effect from fewer particles was stronger in 2020 than the effect of reduced heat-trapp<\/a>ing carbon dioxide emissions, Gettelman said. That\u2019s because carbon stays in the atmosphere for more than a century with long-term effects, while aerosols remain in the air about a week.<\/p>\n

Even without the reduction in cooling aerosols, global temperatures in 2020 already were flirting with breaking yearly heat record because of the burning of coal, oil and natural gas \u2014 and the aerosol effect may have been enough to help make this the\u00a0hottest year in NASA\u2019s measuring system<\/a>, said top NASA climate scientist Gavin Schmidt, who wasn\u2019t part of this study but said it confirms other research.<\/p>\n

\u201cClean air warms the planet a tiny bit, but it kills a lot fewer people with air pollution,\u201d Gettelman said.\n <\/p><\/div>\n
