RALEIGH, N.C., Aug. 25 (UPI) -- A study predicts yields of three of the most important U.S. crops -- corn, soybeans and cotton -- will plummet if temperatures rise due to climate change.
North Carolina State University Assistant Professor of agricultural and resource economist Michael Roberts and Columbia University Assistant Professor of economics Wolfram Schlenker predict U.S. crop yields could decrease by 30 percent to 46 percent during the next century under slow global warming scenarios and by 63 percent to 82 percent under the most rapid global warming scenarios.
