Alaskan and Northwest Canadian Glaciers

Results indicated that "between 1962 and 2006, Alaskan glaciers lost 41.9 ± 8.6 km3 per year of water, and contributed 0.12 ± 0.02 mm per year to sea-level rise," which they note was 34% less than estimated by Arendt et al. (20002) and Meier and Dyurgerov (2002). And in discussing this large difference, they say the reasons for their lower values include "the higher spatial resolution of [their] glacier inventory as well as the reduction of ice thinning underneath debris and at the glacier margins, which were not resolved in earlier work." Thus, in addition to significantly revising what was previously believed about the magnitude of ice wastage in Alaska and northwest Canada in recent decades, Berthier et al. say their results suggest that "estimates of mass loss from glaciers and ice caps in other mountain regions could be subject to similar revisions," all of which would tend to mitigate against the rapidity with which the world's climate alarmists have long contended earth's mountain glaciers and ice caps were wasting away and thereby contributing to global sea level rise.
