Figure 28: Loss of Crop Yields per Degree Warming

Click the image to view and download the full-size version.

Yields of corn in the United States and Africa, and wheat in India, are projected to drop by 5-15% per degree of global warming. This figure also shows projected changes in yield per degree of warming for U.S. soybeans and Asian rice. The expected impacts on crop yield are from both warming and CO2 increases, assuming no crop adaptation. Shaded regions show the likely ranges (67%) of projections. Values of global temperature change are relative to the preindustrial value; current global temperatures are roughly 0.7°C (1.3°F) above that value.
