Many climate change campaigns have used the dramatic photographs of the diminishing snow of Kilamanjara as evidence of global warming.

In fact, the snows have been retreating for decades – perhaps centuries. The real reason for the diminishing snows is deforestation at the base of the mountain. This has resulted in less moisture in the air around the mountain and, consequently, in less snow falling on the peak.

Of course, the fact that diminishing snows on Kilamanjaro is not the result of global warming is no evidence that global warming is not real.
