Himalayan glaciers rebelled against global warming

For years, scientists argue about the state of belonging to China, Pakistan and India, glaciers, covering approximately 20,000 km2 of the Karakoram mountain range in the west of the Himalayas.

Until recently, information on the ice cap on the peaks, including K2 (the second highest mountain in the world), and 3% of the stocks of ice on the planet, was only estimated, despite the fact that in all other regions of the ice volume loss is ascertained from ice- speed up the process of melting caused by global warming.

This is partly explained by the fact that, ground investigation Karakoram impossible. The mountain range is too high, the risk of disappearance of the snow and ice avalanches there is always the maximum.

Therefore, a group of French scientists from the University of Grenoble took advantage of three-dimensional satellite maps from 2000 to 2008, to conduct a more thorough analysis of the Karakoram ice reserves, occupying 5,615 km2 between the Chinese and Pakistani river Yarkant part of the Indus River. The researchers deliberately did not use data on the Siachen Glacier, the localization of the military conflict between India and Pakistan, which in 35 years has decreased by 10 km.

The conclusions reached were quite unexpected: not only that the glaciers have not lost a drop from his previous weight, we can say that they have grown, adding 0.11 mm per year. But this does not negate the fact that in other parts of the glaciers are in critical condition.

Continuing the analysis of data on the melting of Himalayan glaciers, other scientists have shown that the overall losses are available, but they are not as significant and by 2035, the Himalayas has melted, as some climatologists. Instead of 50 billion tons of ice lost only 4 tons per year. This difference in the calculations could be because of an erroneous inclusion in the volume is retained in the drainage systems of the Himalayan foothills of water, which comes from underground sources, and glaciers of of underlying, more exposed to the effects of global warming.

Causes numbness Karakoram ice to raise global temperatures is not clear. Perhaps this is due to changes in atmospheric circulation and precipitation, more snow is in this part of the Himalayas. Although in such an arid mountainous region of possible again due to global warming, allowing air and moisture to accumulate to form the necessary draft.

Able to discuss the ice is extremely important for the whole of Southeast Asia, as they feed the most important waterways that affect the lives of more than a billion of the world population.
