There was a disturbing report on the NHK program "Close Up Gendai":
http://www.nhk.or.jp/gendai/kiroku/detail_3301.html Researchers in Antarctica have mapped the ice and land under it with radar and other techniques. They have found there is a great deal more ice than previously thought and it is more likely to melt. Prof. Andrea Dutton, U. Florida, looked at fossilized coral reefs and determined that the last time Antarctica, Greenland and Iceland melted, the sea level rose ~9 m. That's about 6 m from Antarctica and 3 m from the northern ice. Melting ice at the North Pole will not raise sea levels because that ice is floating. The latest projections indicate this might happen by the year 2100, because of global warming caused by CO2. 9 m is a far higher sea level increase than any previous estimate. - Jed
