Sea level to increase .8 to 2m by end of century

From ClimateProgress:

Scientific analysis is finally catching up to scientific observation. In 2001, the IPCC projected that neither Greenland nor Antarctica would lose significant mass by 2100. The IPCC made the same basic projection again in 2007. Yet both ice sheets already are. As Penn State climatologist Richard Alley said in March 2006, the ice sheets appear to be shrinking “100 years ahead of schedule.”

The loss of ice from the Antarctic and Greenland have led to new predictions of sea level increase this century. A new study in Science Magazine states that "on the basis of calculations presented here, we suggest that an improved estimate of the range of SLR [Sea Level Rise] to 2100 including increased ice dynamics lies between 0.8 and 2.0 m."

It strikes me as sad that scientists have been saying for years that the accumulation of greenhouse gases in the atmosphere will lead to global warming, and when we finally see "unequivocal" evidence of this, someone like Sarah Palin can say "I'm not one though who would attribute it to being man-made". Has she been living in a cave? If not, she may be by 2100.
