One of my habits in recent years has been studying climate history in my free time. What can I say; it keeps me out of bars.
Recently, I was startled to learn that the temperatures experienced by American wheat farms back in the 1830s were almost 7 degrees warmer than they now are.
At first I thought I had misread that statistic. After all, we know that temperatures in our country have been on the uptick since 1850 when North America emerged from a cooler era. And, surely, if climate scientists are right, temperatures in just the past couple of decades are clearly up from what they used to be.
So how could modern American wheat farmers be facing much colder climes than they were in the 1830s?
