The New Scientist reports a new paper by Nicholas Pepin from the University of Portsmouth and his colleagues which suggests that extensive local deforestation in recent decades has likely reduced this flow of warm, moist air up the Kilimanjaro mountainside depleting the mountain’s icy hood. Trees play an important role here by providing moisture through transpiration which add to the ice cap.

Of course it’s possible that global warming led – by some unknown mechanism – to the deforestation — but it seems highly unlikely.
