Sahara grows, but unsteadily

August 1991
New Scientist;8/17/91, Vol. 131 Issue 1782, p15
Comments on research by Compton Tucker and Wilbur Newcomb, of the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center in Greenbelt, Md., and Harold Dregne, of Texas Tech University, who used weather satellites to monitor the changing position of the southern edge of the Sahara. Evidence that the Sahara desert expanded southward during the 1980s as a whole; Fluctuating size of the desert; More.
