One of the latest scares about global warming comes from a new report claiming that climate change is causing drought and killing trees across the Sahel region of sub-Saharan Africa. But according to an article in Forbes by James Taylor, this is surprising news to many scientists and Sahel experts. He notes that in this narrow region stretching from the Atlantic across to the Red Sea, the sand dunes of the Southern Sahara are retreating, and the West African nation of Burkina Faso is growing so much greener that families who fled to wetter regions 20 years ago because of drought are starting to return home. BBC News also reports satellite maps show a recovery of vegetation over the last 15 years, so it sounds like this new concern about the Sahel desert is quite dry on facts.
