Many global warming alarmists tout the notion that anthropogenic global warming will result in widespread crop failures as (projected) climate changes increasingly lead to increasingly bad growing conditions (see our article Science Fiction Down on the Farm, for some examples).
Using Al Gore’s lingo, we are quick to call “BS” on that premise, for the simple fact that that is not how things work. Crop scientists and farmers have an economic incentive to improve genetic cultivars and agricultural practices to maximize output given the prevailing environmental conditions. And, they are pretty effective at what they do. Despite the “global warming” and other affiliated and/or non-affiliated climate changes that have occurred over the past 100 years, global crop production just keeps on increasing—see our recent coverage here of this very good news.
We are clearly and demonstrably able to change agricultural practices to keep up with changing climate while increasing yields.
So much for the “dumb farmer scenario” that farmers stand by and watch their crops fail as conditions change.
But what about those future climate changes that underlie the scare scenarios? Are climate models really able to the climatic factors that are important for agriculture?
A new soon-to-be-published study finds that the models are not so hot, at least over the world’s most productive agro-region, the good-old-US of A. As we shall see, though, the pressures to say the politically correct thing still comes beaming through from the halls of Academia.
