From a Glaciers Perspective "Everest Base Camp has actually dropped from 5,320m to 5,280m since Hillary and Tenzing first set up camp for their ascent there more than fifty years ago." The Guardian had an excellent series of photos earlier this year, showing before and after pictures of retreating glaciers. (I've used one of their photos above) Photos don't lie: some glaciers, at least, are melting!Similarly, this row with the IPCC shows that we simply don't know how climate change will affect the Himalayan glaciers. We know that many have retreated significantly. For instance, the famous Khumbu glacier, from which climbers begin their ascent of Mt. Everest, has retreated by over one kilometer in the last 50 years. In fact, according to the blog
The answer here, is that we need better science about how glaciers are acting and will act. We also need better science about how climate changes will affect precipitation in the region. What we don't need are the typical voices saying that this small (but significant) problem with the IPCC supposedly invalidates all other pronouncements from them.
