Read here. Global warming alarmists and associated IPCC scientists have made erroneous claims about glaciers worldwide. The basic claim is that glaciers are rapidly melting, adding to rising sea-levels because of human CO2-induced warming. As with almost all of these claims, they shrink to minor issues when proper scientific observation is finally applied.
"The five scientists report 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)...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."
