How do you feel about the risk that most of Florida will be underwater in a few decades?

Let the whole state go under. I'll be long gone by then. (All kidding aside, I haven't really heard anything about that, and it isn't a pleasant thought. Any particular articles on the subject that you've seen?)

I'm only half-joking. The sealevel rise estimates are all over the map (no pun intended). For one estimation on the effect on Florida, see: http://www.globalwarmingart.com/sealevel?lat=30.487&lng=...

For one estimate of +2m, see: http://www.reportingclimatescience.com/news-stories/article/...

Again, I don't know how likely this is, but Florida is one of the most vulnerable states in the US. The prize probably goes to Louisiana with North Carolina in the top 3.
