In the last 15 years, all of the 22 glaciers around Lake Issyk Kul (center, between Lake Balqash and the Taklamakan Desert), in Kazakhstan, have retreated. There are a number of reasons for the degradation of glaciation in Issyk Kul, but the increase in surface pollution and climate change are the main ones.
Both contribute to more intense melting and therefore degrade the mass balance of the glacier. The average yearly temperature in the glaciation zone has risen by 0.2ºC; summers are warmer by 0.6ºC, evidenced not only by melting rates but by a longer ablation period. This continued warming trend will accelerate glacial collapse and, most important, lead to a change in the water volume in the rivers the glaciers help to feed (click here for more information).
