Right now, some very hot areas are becoming uninhabitable, and low-lying coastal areas are being flooded. In the US, this has already hit a few areas hard, such as Phoenix AZ [1] and Miami FL.[2]

Phoenix is breaking heat records again this week. The number of days of extreme heat each summer keeps increasing. Phoenix also has limited water sources; it's a city in a desert, after all.

Miami now floods regularly. Levees and berms don't help much; the ground is too porous. Pumping helps; at least a dozen huge pumps have been installed, with many more to come. This is a stopgap measure, the mayor of Miami admits.
