Study Links Climate Change to Lower Crop yields, Higher Food Prices

Climate change has stymied crop yields, contributing to skyrocketing food prices, according to a new study published by the journal Science.

The Des Moines Register reports:

While U.S. farmers have enjoyed a relatively favorable climate, yield gains in other regions over the past three decades have been partially offset by temperature increases…

While corn yields increased worldwide between 1980 and 2008, they would have been 3.8 percent higher if not for higher temperatures, the study said. The climate changes also reduced gains in wheat yields, the scientists said.

The findings are consistent with those of Iowa’s Climate Change Impacts Committee, which issued a report to the governor in January. Continue reading
