A new study from researchers at Kansas State University found that in future decades, at least one-quarter of the global wheat productions will be lost because of extreme weather if no adaptive measures are taken.
The university team projected that wheat yields will decrease by 6 percent for each degree Celsius the temperature rises. If we assume this projection to be true, the temperature increase would result in a loss of 42 million tons of wheat based on the 2012-2013 harvest of 701 million tons.
