This is some scary stuff, check out this glacier in Austria,this is how much it has retreated in just over 100 years. This can have extreme consequences for the Earth
There was also, until recently, no full understanding of how glacier melt was influencing sea level rise. The Intergovernmental Panel on Climate Change (IPCC) left out the effect of melting glaciers and ice sheets in its projections on sea level rise in the 2007 report.
But the Union of Concerned Scientists said new analyses suggested that such meltwater from land-based ice could lead to a sea level rise of 0.8 metre (2.6ft) by the end of the century – and possibly as much as two metres.
Glacier melt is also threatening water supplies, the UCS said, pointing to a 2008 study in the Himalayas which showed less water flowing from the glaciers to the great rivers such as the Indus, Ganges and Brahmaputra that sustain the Indian subcontinent.”
