San Francisco does have cold summers but if you don’t like it you go can to the East Bay, Marin or Peninsula. Those locations are just minutes away. You don’t have that option in New York State. When it’s zero degrees in Syracuse or Buffalo you don’t drive five to ten minutes and have a huge delta in temperature.
Florida has always been humid and hot. This isn’t new. I’m not a scientist but the claims that states can pass legislation that will affect their states weather doesn’t pass the sniff test to me.
If you lived in those areas you don’t drive anywhere to get out of the cold, you enjoy it, winter activities, winter sports, pretty obvious you didn’t participate the short you were in the area, besides, it just completes the change of season, another feature San Francisco misses
Florida has always been hot and humid, but not this hot for this long, with the prediction to continue, and it is not just Florida, you ever spend a summer in Georgia
