Research says: More heat, less food

A study of cereal grain production over 20 years shows rising temperatures have reduced the crop. The study covered wheat, corn and barley which are staples across the globe.

The loss of grain due to heat is not surprising. But the researchers said it's one more piece of evidence that climate change is already at work.

The unaswered question, says this study, is can agriculture adapt quickly enough to the shift in climate? How do farmers differentiate between natrual variability and long-term climate shift? Can we forestall a severe grain drain?
