A third of Himalayan glaciers will melt by 2100

(Climate Action, 5 Feb 2019) A new study has found that a 2 degree temperature rise could melt half of glaciers in the Hindu Kush Himalayan region.

The new study, styled after the IPCC report, is the first and most authoritative study of its kind. Developed over five years, it includes insight by more than 350 researches into the regions distinct environment, people and wildlife.

The report finds that even the most ambitious 1.5 degree Paris target will result in a 2.1 temperature spike and the melting of one third of the regions glaciers, a critical water source to some 250 million mountain dwellers and the 1.65 billion others living in the valleys below.

The report warns that if global climate efforts fail then it would result in a loss of two thirds of the region’s glaciers by 2100.  

The HKH region covers over 3,500 kilometres and nestled in its record-breaking peaks, glaciers feed 10 of the world’s most important river systems, including the Ganges, Indus and Mekong. Additionally, the region contains four of the world’s biodiversity hotspots.

Despite the glaciers being formed over 70 million years ago they are surprisingly vulnerable to climate change. Since the 1970s, when global warming first set in, these ice mases have steadily thinned and retreated.

Philippus Wester of the International Centre for Integrated Mountain Development (ICIMOD), who led the report, said: “This is the climate crisis you haven’t heard of. Global warming is on track to transform the frigid, glacier-covered mountain peaks of the HKH cutting across eight countries to bare rocks in a little less than a century.”
