Actually parts of Louisiana are below sea level. IIRC, Baton Rouge is surrounded by dikes holding back the sea. Or maybe it was New Orleans. One of them Louisiana Cities, anyway.

What data do we have on rising sea level? Surely if the planet is warming rapidly, the sea level will already have changed some. Do we have a comparison between mean tide level now and (say) 50 years ago at some point on the planet? Do any of our scare-tactic experts have this data?
