"Each degree Celsius increase in global mean temperature is estimated to reduce average global yields of wheat by six percent," said the report. Rice yields would be cut by 3.2 percent, and maize by 7.4 percent for each degree of Celsius warming (almost two degrees Fahrenheit), it added. This file photo taken on August 19, 2013 shows a wheat field near Tioga, North Dakota. "Estimates of soybean yields did not change significantly." Changing temperatures would likely cause yields to rise in some locations, said the report.
