From 1962 to 2006 the glaciers of the Himalaya appear to have lost more than a fifth of their ice. They did not all shrink at the same rate. In fact, some glaciers haven't shrunk at all, but measurements of the overall trend in the Sikkim-Nepal region put the average loss at seven inches of depth every year across the whole extent of ice. And, of course, the melting continues.
