Climate change may impact crops within 10 years
Global climate change may affect the production of maize (corn) and wheat as early as 2030 under a high greenhouse gas emissions scenario, according to a new NASA study published on November 1, 2021, in the peer-reviewed journal Nature Food. Maize crop yields are projected to decline 24 percent, while wheat could potentially see growth of about 17 percent.
Using advanced climate and agricultural models, scientists found that the change in yields is due to projected increases in temperature, shifts in rainfall patterns and elevated surface carbon dioxide concentrations from human-caused greenhouse gas emissions. These changes would make it more difficult to grow maize in the tropics but could expand wheat’s growing range.
