| Summary: | nexpected accelerations in outlet gla-ciers of the Greenland and Antarctic ice sheets in the last decade, in response to processes not fully understood, prompted the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment to conclude that poorly characterized uncertain-ties prevented a best estimate or upper bound on sea-level rise. These changes in ice sheet outlet glaciers come at a time when smaller gla-ciers and ice caps are wasting quickly as well. The focus of present glacier research must be the rapid reduction of the uncertainty identified by the IPCC. Rapid progress will require iden-tification of the most relevant of the recent |
