Sea Level Rise
Since this is in centimetres could you juxtapose these figures with any level of uncertainty with the 20 feet rise should Greenland and the WAIS both melt? I watched Lomborg testify in Congress and this was the one point he made of Gore's film where he claimed it was false beyond any doubt.
[Response: Greenland ice is good for 7 metres and the WAIS for 6 metres of sea level rise. 20 feet is about 6 metres so either ice sheet alone, or half of each, could lead to a 20 feet rise. -stefan]
