Corn Could Be Major Victim of Climate Change

Researchers say the possibility of drought hitting multiple corn-growing regions hard in the same year is real.

The weather has always been an unpredictable element of agriculture, but climate change is expected to make matters significantly worse. Determining how much worse has historically been a challenge. A new study, however, says climate-induced drought could hit several of the world's major corn producing regions all at once.

The Met Office, the U.K.'s national weather service, used a novel approach to determine the probability of severe water stress in three major corn-producing regions that are responsible for 40 percent of global production . Instead of relying on observed historical data—which the researchers found to seriously underestimate the impact of climate change—the new study used a model focusing on water stress. The authors noted the limitations of the study, including its reliance on a single climate model, and they advise researchers to utilize multiple models in the future.
