Covid Shutdowns Actually Heated Up the Planet – a Bit
During the Covid shutdowns, fewer people were driving cars and that meant that fewer particles made their way into our air. Clearly less pollution in our air is a good thing.

So when there are fewer of them, more sunlight makes it to the ground – which heats things up, at least a bit. Here are all the details in an article released in Geophysical Research Letters.
