Africa: Cloud forests, water source to millions, face risk

A warming climate threatens tropical mountain forests that strip moisture from clouds and supply water to millions of people in Africa and Latin America, experts said in a U.N. report released on Monday. Cloud forests in equatorial and sub-equatorial regions of Latin America, Africa, and Asia account for just 2.5 percent, or 400,000 sq km (154,000 sq miles) of world tropical forest cover. But the benefits are felt way beyond their boundaries.
