Decline in wheat yields likely due to changing climate

Global wheat production can be expected to fall by 6% for each degree centigrade of temperature increase together with increased variability of yield across regions and seasons; that is the main finding of an international consortium of researchers including the James Hutton Institute, who have used a systematic multi-model test to make use of data from field and artificial heating experiments to focus on the responses of wheat to high temperatures.

The paper 'Rising temperatures reduce global wheat production', by S. Asseng et al, is available from Nature Climate Change, and more information about AgMIP can be found on the project website.
