Satellite images confirm uneven impact of climate change
University of Copenhagen researchers have been following vegetation trends across the planet's driest areas using satellite imagery from recent decades. They have identified a troubling trend: Too little vegetation is sprouting up from rainwater in developing nations, whereas things are headed in the opposite direction in wealthier ones. As a result, the future could see food shortages and growing numbers of climate refugees. (2020-11-26)
