::The statement at the lead of the article, 'The bedrock in the center of Greenland has been pressed below sea level by the weight of the ice sheet, so that if the ice were to melt, much of central Greenland would be under water.' seems very suspect to me. During the time it would take to remove that amount of ice there would be so much isostatic rebound that it would be unlikely that the bedrock would be below sea level. Is there a citation that actually says this?
