The retreat of the glacier on Kilimanjaro was used by Al Gore to show the effects of global climate change. The causation of this phenomenon has been called into question, and critics have cited a “study” which supposedly blamed the disappearance of the glacier on deforestation. That is nonsense. Forests don’t “pump moisture into the air.” Trees consume water and carbon dioxide, and produce oxygen and fixed carbon products. And the “study” was not a study. It was just somebody’s idea in a newspaper story. For the lowdown on the complexity of Kilimanjaro, see this.
