Mount Everest glacier

Mount Everest's growth, about 2 mm/year, is driven by isostatic rebound from the Arun River's erosion. This surprising force also impacts neighbouring peaks like Lhotse and Makalu.

Web story: Kangchenjunga (8,586 m) was believed to be the highest mountain in the world from 1838 until 1852, when the Great Trigonometrical Survey of India identified Mount Everest as higher.

Every year, more than 450 climbers from around the world get permits from the Nepal government to climb Mt. Everest, and this number is constantly growing.

It is not new that glaciers around the world are losing mass, but until now little was known about what is happening to ice above 5,000 meters.
