The warmer world is likely to be a hungry world. Heat can be devastating to crops and climate change will significantly reduce crop yields. In many places, it already is.

A recent newspaper headline, ripped from the front page of the San Francisco Chronicle’s business section, reads “World’s Wheat Crop Stressed.[1] According to the article, “Yields aren’t keeping up with a world growing hungrier. Crops are stunted in a world grown warmer. A devastating fungus, a wheat ‘rust,’ is spreading out of Africa, a grave threat to the food plant that cover’s more of the planet’s surface than any other.”[2] The article continues, “In the face of leap-frogging prices, stagnating yields and shifting climate zones, wheat cannot be counted on to fill humankind’s stomach in the future as it has since at least 7000 B.C.”[3] This article is right to call attention to the multitude of social and scientific factors that combine to create food insecurity.
