If nothing else, let’s keep in mind the Dust Bowl… if changing climate patterns made our farms far less productive - even if only for 4 years or so… - we’d have problems.

This just isn’t true. We just had a drought that matched the Dust Bowl, only a few years ago.* Didn’t you notice? The agricultural community did, I assure you, but vastly improved farming practices prevented any large-scale shortfalls of grains and mitigated the week-long dust storms, and with agriculture being a much less prominent sector of the economy these days the general economy scarcely felt a thing.
*I’m not sure if it was quite as widespread, but it was comparable in severity throughout the Canadian prairies. The driest year on record in Saskatoon by a huge margin was 2001.

Outside of '36 and '37, the drought of the 30’s wasn’t that bad here. From what I’ve heard from my parents and grandparents, the biggest problem in the 30’s (aside from those two years) wasn’t that there was no crop, but that the crop was worth virtually nothing. In raw precipitation, the drought of the late 80’s was similar to the 30’s, and this most recent one blows it away.
