Earth heats up due to pandemic’s cleaner air, study finds

Earth spiked a bit of a fever in 2020, partly because of cleaner air from the pandemic lockdown, a new 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.

This temporary warming effect from fewer particles was stronger in 2020 than the effect of reduced heat-trapping carbon dioxide emissions, Gettelman said. That's because carbon stays in the atmosphere for more than a century with long-term effects, while aerosols remain in the air about a week.
Well, shit.

Is no one even reading the post lol

It results in higher temps, but as they only last so long, the cumulative effect is much much smaller than Carbon Dioxide as that sticks around for so long, basically compounding the increase again and again.

We are fully in "Put your head between your knees and kiss your ass goodbye" territory it seems.

This is going to be gold for all the climate deniers, isn't it?

This is a pretty well-known phenomenon, but the temporary increase in temperature is not nearly as bad as all that CO2 in that atmosphere.

It's just another indication of how fast we need to reduce emissions since the aerosol effect hides some of the heating.

* A conservative talking point enters the room. "Its a scientific FACT that pollution is good for the earth. Checkmate you dirty Prius driving vegan liberals."

Suddenly they will "care" about the science, errr, truth, ummm facts.... ohh ok, just this single fact, because it is the only one that aligns with their economic and political agenda.

Isn't it the other way around? The cooling caused by aerosols is temporary?

This doesn't equate to decades of climate change that drastically alter our climate. There is a natural degree of climate change, but the earth would not be doing what man-made climate change does on its own.

This is actually one of the criticisms of geo-engineering, where if we ever stop an intervention, the temperature will snap back rapidly and make things tremendously bad.

This might explain why the La Nina winter has been warmer than usual. The PNW was supposed to be cold but we've had a lot of rain in the ski areas.

This is a known impact of reducing coal consumption. The long term impact of less CO2 is WAY more important than the short term impact of fewer aerosols. It's also the reason some scientists think that aerosols are masking around ~0.2C of warming at the moment.
