Attention, Illinois corn farmers: Award-winning Stanford junk climate scientist Chris Field claims that if summer temperatures exceed 84 F once every five years, you'll start seeing impacts on yield

Climate scientist addresses misconceptions about climate change

"Farmers might have enough rain on average to grow corn in Illinois. But in a drought, as in 2012, yields get whacked. Corn yields decline rapidly when temperatures rise above 29 C (84 F). If temperatures are above that 29 C threshold once every 200 years, it may not be a big problem. But if it is every five years, farmers start seeing impacts on yield and, if the high temperatures occur too frequently, on the viability of corn farming in that area.

Farmer: Ask any corn farmer if his crop "likes it cool"

The crop has its ideal growth at 93 [degrees] F.
