Climate change bugs climbers on Everest
In another ominous sign of global climate change, climbers on Mount Everest are reporting that they are finding house flies in Base Camp for the first time. According to this story from The Guardian, the insects began appearing earlier this year, catching mountaineers, including the Sherpas who call the Himalaya home, completely off guard.Everest BC sits at 5360 meters (17,585 feet), an altitude that was considered too cold and in hospitable for most bugs in the past. But the appearance of the insects was just another indicator of the impact of global warming on the Khumbu Valley, which has seen its glaciers recede at a rate of 10-20 meters per year. Further evidence can also be found in the mountain villages, where water sources are running dry, forcing inhabitants to hike miles each day for supplies.
These changes are having a direct impact on the tourism to the region as well. Each year, hundreds of climbers come to Everest to make an attempt on the world's tallest mountain, and hundreds more trekkers make the hike up to Base Camp, taking in the mountain scenery that is unmatched anywhere else in the world. But with water supplies dwindling, there is less for the visitors to the Khumbu to drink as well.
Worse yet, the warming is changing the summit of the mountain itself. In the article above, Dawa Sherpa, a mountain guide who has reached the top of the world twice, says that in years past, as many as 50 people could stand on the summit of Everest. Now, fewer than 18 can be at that point at the same time, thanks to the shrinking of the cornice. Worse yet, it is likely to get smaller still in the years ahead.

If the summit temperature never rises above -15 degrees F how does the ice or snow up there ever melt?

It's not so much that the snow and ice are melting at the summit, although temperatures there do continue to rise, and the -15º F number is not always accurate any more. The real cause of the shrinking summit is due to less snow and ice falling on it, causing the cornice to shrink in size and become less solid.
