Greenhouse gases may spell wet future for Africa
Historic damp periods linked to boosts in planet-warming emissions
By Beth Mole
A flood of greenhouse gases into the atmosphere may trigger downpours in certain parts of Africa.
By examining a historic African rainy spell, scientists determined that greenhouse gases play a large role in boosting rainfall in northern and southeastern areas of the continent. The finding, appearing in the Dec. 5 Science, may portend how climate change will alter access to a critical resource —water —plus help scientists understand other climate data that predict surges in African rainfall.
