Climate change are reducing the yield of wheat crops in the United States

Rising temperatures brought about by climate change are reducing the yield of wheat crops in the United States, a study published in the journal Proceedings of the National Academy of Sciences, or PNAS, said.

article-2333381-03C8B8FB0000044D-904_634x360Extreme heat in the spring and unusually cold temperatures in the fall are the main factors behind the loss of yield in wheat fields, the report said.

“The overall effect of warming on yields is negative, even after accounting for the benefits of reduced exposure to freezing temperatures,” the team of researchers led by Jesse Tack, of Mississippi State University, said.

“Our results also indicate that warming effects will be partially offset by increased rainfall in the spring,” the study said.

Tack and his team analyzed Kansas wheat variety field trial outcomes for 1985-2013 and day-to-day climate conditions.

The researchers concluded that to preserve sustainable agriculture in a context of global climate change, it will be necessary to design high-yield and heat-resistant wheat varieties.
