Joerg Schaefer, a climate geochemist at Columbia Universitys Lamont-Doherty Earth Observatory, said the new MOES report contains a comprehensive review of temperatures and precipitation changes in HKH. The retreat means countries like Nepal and Bangladesh, which rely on these mountain water cycles, will have to adapt. 18 The observed annual retreat rate of 1.6%/a for the Naimona'Nyi glaciers significantly exceeds the 0.42%/a for the entire western Himalayas, 0.41%/a for the middle Himalayas, and 0.57%/a for the eastern Himalayas (1980-2010).

The results represent an early step toward developing what researchers hope will become the ability to forecast whether a slow-moving landslide will fail and slide downhill. Glaciers are retreating worldwide, exposing new terrain to colonization by plants. What is noteworthy is how little detailed knowledge there is of this region, which is considered to be highly vulnerable to climate change and to be warming faster than many other areas on the planet.

The Athabasca Glacier is not alone in its retreat: Since 1960, glaciers around the world have lost an estimated 8,000 cubic kilometers (1,900 cubic miles) of ice. The work involves spending time clambering up and down the ice, taking measurements and readings to calculate mass balance - the sum of the snowfall which builds up on a glacier and the melting that shrinks it.
