Warming Climate to Result in Reduced Corn Production; Irrigation Blunts Effect
Published:22 Feb.2022 Source:Penn State
No matter which of the widely accepted global circulation models ultimately comes closest to predicting the amount of warming caused by climate change, corn production will be reduced, according to a new study by Penn State researchers.
They evaluated the potential impacts of 18 warming scenarios, dictated by various atmospheric greenhouse gas concentrations, to determine the potential effects of future climate change on irrigated and rainfed corn yields from the 2020s through the 2090s. Although the research was focused on the U.S.Great Plains -- in the heart of the nation's top corn-producing region -- the results are believed to have global implications.
