Warming temperatures have already impacted wheat yields–in the U.S. David
Biello reports
Climate change may already be hitting youin the stomach. A new analysis reveals
that higher average temperatures in Montana over the last six decades equal less
wheat.
Plant scientist Luther Talbert of Montana State University and his colleagues
looked at weather records for the Mountain State from 1950 to 2007. The month of
March has had the most warming overall, increasing by nearly 0.1 degrees Celsius
per year on average. As a result, farmers now plant wheat 10 days earlier.
In addition, higher temperatures in July linked up to less wheat to harvest and
lighter grains.
