Ice Sheet Loss from Greenland and Antarctica Track Worst-case IPCC AR5 Projections

Nature Climate Change, August 31
 

The Greenland and Antarctic ice sheets have increased global sea level by 12.3 mm from 2007 and 2017, matching the most pessimistic predictions of the IPCC’s most recent assessment report (AR5). In particular, this study indicated that current models underestimate the contribution of ice sheet surface melt.  The comparison continues a longstanding trend for observations in polar and other cryosphere regions to most often track with the high extremes of past IPCC report projections.
