   Pandemic's cleaner air added heat to war

   Study: Pandemic's cleaner air added heat to warming planet   
      
   Earth spiked a bit of a fever in 2020, partly because of cleaner air   
   from the pandemic lockdown, a new study found.   
      
   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's due to less soot and   
   sulfate particles from car exhaust and burning coal, which normally   
   cool the atmosphere temporarily by reflecting the sun's heat,   
   Tuesday's study in the journal Geophysical Research Letters reported.   
      
   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.   
      
   "Cleaning up the air can actually warm the planet because that (soot   
   and sulfate) pollution results in cooling" 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.
