Atlas of global warming

The United Nations environment agency unveiled a new atlas yesterday that shows what the agency says are the dramatic effects of climate change on Africa.

The nearly 400-page long publication features more than 300 satellite images taken in every African country.

The before and after photographs, some of which span a 35-year period, appear to show striking environmental changes across the continent.

According to the atlas, Africa is losing more than 4 million hectares of forest every year - twice the world's average deforestation rate.
