^^^ Yeah Miami is already having problems with frequent coastal flooding at high tide even without significant adverse weather. Miami is likely to become some sort of futuristic Venice where it will eventually be hundreds of highrises with the first 2-3 floors flooded and the lobby just moving up a floor as needed. The big existential threat to Miami is what happens if one of those nasty nasty storms that blew up in the Gulf last year lands a direct "dirty side" blow on Miami after feeding on global warming charged waters.
But I think the city with the biggest global warming target on it's back is Houston. They've had three or four "100 year" flooding events in the past 4 years alone. At what point does that entire area just become toxic to insurance companies and everyone is forced to leave or live their at their own risk? I mean Hurricane Harvey dumped 5 feet of rain in some places, how the hell are you supposed to live with storms like that happening? And it would be one thing if it were some freak event, but this is now the third or fourth time in the last few years Houston has been destroyed by flooding.
We just had a 100 year flooding event at my family cottage up on the Wolf River in Wisconsin which was coursing with all the meltoff from that late season blizzard that dumped 30+ inches around Green Bay. I've never seen the river that deep before, it was overtopping everyone's seawall. We just had a flood survey done to try to prove we were out of the 100 year flood plain which massively reduces our flood insurance. Sure enough 90% of our yard was above that plain. And guess what, the water stopped almost exactly where the lines on the survey were. So my point is we have a shit ton of knowledge on weather patterns accumulated over a century or more. 100 year floods are 100 year floods, they simply do not happen three or four times in a row. We've had the cottage in our family for 20+ years and it's never even come close to the top of the seawall. Now we know what the 100 year event looks like and shouldn't see it again for a long time. It's not normal to have 3 or 4 in a row, that's just really freaky. It either means our climate science for the Houston area is wayyyyy off or it means that the old 100 year flood standard is no longer accurate which means a lot of people are going to have to move.
PS: Literally the first thing I did after posting this was check the weather because it started raining and I saw this:
That's the remains of the first named tropical storm of the season still spinning 800 miles inland. That's just bizarre, we get the remnants of tropical depressions up here all the time, but they don't stay fully formed like this. It probably has something to do with, I dunno, 90+ degree temps in late May in the Midwest...
