“If the screwbean mesquite disappears, it will be a huge loss for migrating and desert riparian birds,” says Warren. “Experts have pointed out that screwbean mesquites are dying in many places where there has been no tamarisk control,” says Warren.
But this study is among the first to model how wind and solar farms would affect the Sahara, all while considering how growing green plants and trees would respond to these changes, said Li, who started the study while a postdoctoral researcher in the Department of Atmospheric and Oceanic Science at the University of Maryland.
