Warren,
Not all of the predictions were for 100 years for now. Some were for things to start changing in as little as 7 years. Worse storms and those islands in the Southern Pacific that are vanishing are happening now. And I agree with what the guy said about Katrina. we never learned a thing from her. Just business as usual. Some places on the Northern Calif. coast line have lost over 100' in the past few years. A lot from erosion but that was mostly caused by larger breakers and less break water islands and such.
