Some scientists think that if the sea level rise should speed up and destroy a massive, unstable ice sheet in western Antarctica, the oceans could go up as much as 18 feet and inundate many coastal regions of the world.
‘No one knows how rapidly it can happen,” says Robert Etkins of the National Oceanic and Atmospheric Administration. –It could be 50, maybe even 200 years.
Another scientist who agrees is James Hansen of the Goddard Institute for Space Studies in New York.
1982 + 50 = 2032. Eighteen feet of sea level rise in the next eighteen years.
