> What you see is that Bangladesh goes from being a habitable city one year to one which is underwater 1/4 of the time, look at the massive floods there this year. Next year might be dry, but the year after that? It is already not sustainably habitable, but the people still live there.

Really bad example. Floods have always been a problem in Bangladesh.
