A Stanford University researcher says the world’s crop models may have underestimated the impact of global warming on global wheat yields, according to an article from UPI.

Researcher David Lobell pointed to an area of India known for its wheat production. Lobell found that winter wheat in India is turning brown earlier in the spring, prior to harvest. Higher average temperatures are having a significant effect, with temperatures higher than 93.2 degrees F having the most impact.

Lobell’s research highlights the need for more research into how hot spells impact wheat yields around the globe. As global temperatures are expected to rise, more, longer periods of heat could reduce global wheat yields.
