Global Warming and the Glacier Retreat: An Overview

摘要: Glacier ice cover, in the Himalayas, at height of Last Glacial Maximum – around 65,000 years BP had extended to 20 odd kilometres downstream present glacier snout positions. Glaciers, for whatever reason, stayed put these altitudes till up end LGM 12–15 ka BP. Current phase retreat Himalayas which began this time and has been continuing since not gradual but spasmodic. There have periods relative halt or stand still preceded succeeded by rapid with drawl melt, obviously response some climatic oscillation. glaciers historical based on data generated over last 150 so, is, more less, constant continuance secular that glacial cycle likewise Periods alternating slow order almost still. At no area vacation from under cover what can be termed as alarming/abnormal, especially decade so. So far observation glaciers, than five decades now, allows a judgment, I hesitation making statement does necessarily respond immediate changes. Illustrated account few selected varying dimensions, different physiographic zones having an record 100 years, sited enable readers arrive proper conclusion regarding: (1) (2) impact global warming. Data presented reveals fact fluctuation is influenced one single parameter combination parameters. Physiographic character accumulation zone valley slope probably dominant role annual precipitation atmospheric temperature per se. Local changes front may sometimes show close relation parameters could mere coincidence and, it would come any limited available.
