Bummer: CO2-induced planetary overheating could cause walnut trees to die from cold weather

Climate Change May Be Fatal for Walnuts

Warmer, drier summers and extreme weather events considered possible as the climate changes would be especially troublesome-possibly fatal-for walnut trees, according to research at Purdue Univ.

Walnuts are also sensitive to cold, so much so that they have developed a defense mechanism against late frosts. Jacobs says walnut trees don't begin sprouting leaves until almost a month after other trees in the spring.

That defense mechanism could be compromised by extreme weather events associated with climate change scenarios. Late spring frosts after walnuts have developed leaves could kill trees.
