In contrast, global temperature in at least the
past two decades is probably outside the Holocene range (7), as evidenced by the fact that the Greenland and Antarctic ice sheets are both losing mass
rapidly (8, 9) and sea level has been rising at a rate [3 m / millennium, (10); updates available at http://sealevel.colorado.edu/] well above the average rate
during the
past several thousand
years.
