Seems like a lot of people staring at correlations without a lot of causal reasoning (why is hotter, wetter climate worse for the virus? Is it because of more background bacteria? Is it just a way to find the omitted variable of exposure to sunlight etc etc).

That being said, pretty maps!

I understood that ultraviolet light is a good sterilizer. There's more light in summer. Maybe that covers it.
