Mt. Kilimanjaro and the global retreat of glaciers

What The Science Says:
Mount Kilimanjaro's shrinking glacier is complicated and not due to just global warming. However, this does not mean the Earth is not warming. There is ample evidence that Earth's average temperature has increased in the past 100 years and the decline of mid- and high-latitude glaciers is a major piece of evidence.

Climate Myth: Mt. Kilimanjaro's ice loss is due to land use
'Gore claims the snowcap atop Africa's Mt. Kilimanjaro is shrinking and that global warming is to blame. Yet according to the November 2003 issue of Nature magazine, "Although it's tempting to blame the ice loss on global warming, researchers think deforestation of the mountain's foothills is the more likely culprit. Without the forests' humidity, previously moisture-laden winds blew dry. No longer replenished with water, the ice is evaporating in the strong equatorial sunshine."' (James Taylor)

Indeed deforestation seems to be causing Mount Kilimanjaro's shrinking glacier so Gore got this wrong. But Philip Mote, author of the study in Nature, puts it in perspective: "The fact that the loss of ice on Mount Kilimanjaro cannot be used as proof of global warming does not mean that the Earth is not warming. There is ample and conclusive evidence that Earth's average temperature has increased in the past 100 years, and the decline of mid- and high-latitude glaciers is a major piece of evidence."
