Climate Change: Extreme heat can cause wheat crops to age faster and reduce yields

Reuters - Scientists and farmers have long known that high heat can hurt some crops and the Stanford University-led study, released on Monday, revealed how the damage is done by tracking rates of wheat ageing, or senescence.

Depending on the sowing date, the grain losses from rapid senescence could reach up to 20 percent, the scientists found in the study, published in the journal Nature Climate Change.  Read more.
