Coastal Floridian checking in. I don't deny global warming but at the moment there is no widespread immediate threat to property caused by rising sea levels where I live. Not to say there won't be in a generation or so.
The more immediate threat is the environment effects of overpopulation and pollution in the waterways. I remember fishing in the lagoon by my house when I was a kid and the water being super clear and full of fish. Now, it's been overfished; you can only catch undesirable bottom feeder type fish. It's also a constant brown caused by runoff from residential areas.
