I have lived here in South Florida for over 30 years and when the iconic South Beach flooded, it was a major, and I mean major news event.
Now it happens 3 or 4 times year. The water keeps rising. There is even debate over whether to just buy some areas out and move them to higher ground (at taxpayer expense of course).
For whatever reason, man or otherwise, things are getting warmer. We keep breaking all-time temperature records regularly here. In 2019, we had about 150 days of temperature over 90 F (32 C). Nearly 150 days at or above that temperature when the average is typically about 85 days.
Forecasted high today at the beginning of winter (4 Jan 2020) is 86 F (30 C) which would tie an all time record. Another degree and it is broken.
There may be multiple factors involved, but you can't just keep dumping shit into the air, which retains heat when sunlight hits it, and expect to keep a "normal" environment.
