The average elevation of Florida is 98 feet. Most of the state — at least along the coast — is less than 10 feet or so above sea level. Global warming causes oceans to rise, and with a six-foot rise you can pretty much kiss Miami goodbye. Come to think of it, say goodbye to white sandy beaches, super expensive dock-side McMansions, and nightclubs I'll never be cool enough to get into. Heck, with just a three-foot rise in water level, say goodbye to Key West, too.
