Glacier recession and expansion in Hindu Kush-Himalayas and Central Asia Glacier recession and expansion in Hindu Kush-Himalayas and Central Asia
Averaged over their entire areas, within the period 1960– 2003 glaciers in Patagonia and Alaska have thinned by ap- proximately 35 m and 25 m, respectively, whereas high mountain glaciers in Asia have thinned by over 10 m. Data for Patagonia and Alaska are computed from glacier surface elevations for dozens of glaciers. In many other high moun- tain environments such as the Himalayas and the high Andes, where data are limited due to bo...
