Professor Sinninghe Damste’s research, as discussed on the site of the Dutch Organization of Scientific Research (DOSR) — a governmental body — shows that the icecap of Kilimanjaro was not the result of cold air but of large amounts of precipitation which fell at the beginning of the Holocene period, about 11,000 years ago.
The melting and freezing of moisture on top of Kilimanjaro appears to be part of “a natural process of dry and wet periods.” The present melting is not the result of “environmental damage caused by man.”
Professor Damste studied organic biomarker molecules in the sediment record of Lake Challa, near Mount Kilimanjaro, and reconstructed the changes and intensity of precipitation in this part of Africa over the last 25,000 years. They observed an 11,500 year cycle of intense monsoon precipitation.
In the dry period between 12,800 and 11,500 years ago, Kilimanjaro was ice-free.
