Himalayan glaciers are growing, not shrinking as predicted

Researchers have discovered that contrary to popular belief half of the ice flows in the Karakoram range of the mountains are actually growing rather than shrinking.There seems to be a lot about our climate that the globo warmers do not know. You would think they would get the observable basics before they go off trying to control the earth's thermostat.
The discovery adds a new twist to the row over whether global warming is causing the world's highest mountain range to lose its ice cover.
It further challenges claims made in a 2007 report by the UN's Intergovernmental Panel on Climate Change that the glaciers would be gone by 2035.
Although the head of the panel Dr Rajendra Pachauri later admitted the claim was an error gleaned from unchecked research, he maintained that global warming was melting the glaciers at "a rapid rate", threatening floods throughout north India.
The new study by scientists at the Universities of California and Potsdam has found that half of the glaciers in the Karakoram range, in the northwestern Himlaya, are in fact advancing and that global warming is not the deciding factor in whether a glacier survives or melts.
... the key factor affecting their advance or retreat is the amount of debris – rocks and mud – strewn on their surface, not the general nature of climate change.
Glaciers surrounded by high mountains and covered with more than two centimetres of debris are protected from melting.
Debris-covered glaciers are common in the rugged central Himalaya, but they are almost absent in subdued landscapes on the Tibetan Plateau, where retreat rates are higher.
In contrast, more than 50 per cent of observed glaciers in the Karakoram region in the northwestern Himalaya are advancing or stable.
