The rapid transformation of the landscape of Africa has been brought into sharp focus by the publication of an atlas by the United Nations Environment Programme.

RWENZORI MOUNTAINS, UGANDA
Climate change has caused the glaciers in this Ugandan equatorial mountain range to shrink dramatically. The UN says they halved in size between 1987 and 2003 (there are fewer white areas on the second image), during which time higher temperatures and decreasing cloud cover also have contributed to sublimation - direct vaporisation of ice without melting.
According to the UN, researchers believe that, at the current rate of reduction, they will have disappeared within 20 years.
