Himalayan glaciers not melting because of climate change, report finds
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.
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.
And the science behind the story:
Dr Bodo Bookhagen, Dirk Scherler and Manfred Strecker studied 286 glaciers between the Hindu Kush on the Afghan-Pakistan border to Bhutan, taking in six areas.
Their report, published in the journal Nature Geoscience, found 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.
"Our study shows that there is no uniform response of Himalayan glaciers to climate change and highlights the importance of debris cover for understanding glacier retreat, an effect that has so far been neglected in predictions of future water availability or global sea level," the authors concluded.
Dr Bookhagen said their report had shown "there is no stereotypical Himalayan glacier" in contrast to the UN's climate change report which, he said, "lumps all Himalayan glaciers together."
How much money has been wasted on this fraud and why are some idiots still buying into it...
Climate = Variable
End of story...
