Deforestation seems to be causing Mount Kilimanjaro’s shrinking glacier. Researchers think deforestation of the mountain’s foothills is the most likely culprit. Without the forests’ evapotranspiration of humidity into the air, previously moisture-laden winds blowing across those forests now blow drier. The summit, no longer replenished with water from those winds, started shrinking. Studies show the ice is evaporating through a process called sublimation. You can witness this effect at home, have you ever noticed that ice cubes left in your freezer tend to shrink with time?

Last year, a British Court ruled Gore’s point about Kilimanjaro not to be true.
