Glaciation Guesswork By 'Warmists' Radically 'Revised.'

'In southeastern Greenland about 43 percent of the glaciers sped up in the first half of the decade, but around 25 percent slowed down by more than 15 percent from 2005 to 2010. These new results have led to climate scientists revising estimates of the effect of melting Greenland ice on sea levels from 46.7 cm to 9.3 cm by 2100.' Consider how wrong the old estimate was to the new in percentage terms!
