> Doesn’t Chicago have a bunch of people die every time there’s a heatwave because of lack of AC and such?

There was a heatwave in the 1990s that killed thousands in Chicago. Since then, the city has done a lot to handle them. While people still die during heatwaves, not as many as would have prior to all of the planning and effort. I guess it depends on how you define “a bunch”.

The growing risk factor for Chicago is flooding and dangerous storms. So far this is causing economic damage but not really killing anyone. Who knows if that holds.
