Climate change will start impacting global supply of corn and wheat as early as 2030, NASA study finds

Global crop supplies are facing a grim future because of climate change. New research from NASA shows that by the end of the century, the availability of corn, wheat, soybeans and rice are projected to look drastically different — and that the world will start feeling the implications as early as 2030.
The study, published Monday in the journal Nature Food, used advanced climate and agricultural models to analyze the future of global food production. Over the next decade, they found, the projected increases in temperature, changes in rainfall patterns and increased surface carbon dioxide concentrations will change agriculture around the world.
"Major shifts in global crop productivity due to climate change are projected to occur within the next 20 yr [years]," the study says, "several decades sooner than estimates based on previous projects."
