Corn is the world's most important grain, based on production volume. The US produces about one third of the global crop. Increasing temperature stress on corn is predicted to reduce global yields by 45% by late in this century.
Increased nighttime temperatures disrupt the pollination process, reducing grain yields by more than 80%. Finally there is an increasing risks of a simultaneous shock to global corn production with far reaching impacts.
Yields of major staple crops like wheat and rice are being hurt by increasing temperatures. Wine grape production is moving to cooler climes causing changes in the character of some of our favorites. The flavors and health benefits of teas, the size of potatoes, the sting of a hot pepper, where fish call home in the oceans, and a future decline in protein in vegetables—it’s all changing.
Our food database shows the ingredients affected by a changing climate.
To learn what farmers, scientists, and many others are doing to keep the menu stocked, see Stewardship of the Land and Our Changing Menu: Climate Change and the Foods We Love and Need. You have a role, too!
