Some African lake levels dropped six feet in the past three years
"An extreme example lies 1,500 miles northwest of here, deeper in the drought zone, where Lake Chad, once the world's sixth-largest, has shrunk to 2 percent of its 1960s size. And the African map abounds with other, less startling examples, from Lake Turkana in northern Kenya, getting half the inflow it once did, to the great Lake Tanganyika south of here, whose level dropped over five feet in five years.
"All these lakes are extremely sensitive to climate change," the U.N. Environment Program warned in a global water assessment two years ago." Link
