Known as the 'Roof of Africa', Mount Kilimanjaro's snow cap is melting fast and could be gone in two decades. Kilimanjaro is one of Tanzania's hotspots, attracting some 20,000 trekkers every year.

Researchers say that the glaciers on the top of Kilimanjaro measured 12 square kilometres (sq km) in 1912 but had shrunk to just 2.6 sq km by 2000. Although scientists say glaciers elsewhere are melting due to global warming, they feel further work needs to be done to establish the cause of Kilimanjaro's meltdown.
