The dust bowl had nothing to do with climate change as you say. It was typical drought patterns combined with ultra-irresponsible farming techniques that caused that. It was a short term, mainly man-made diaster that affected a small area (in the scheme of things).
Presented here is a long term man-made climate shift that affects an entire continent.
It was the F1 tornado to a category 2 hurricane, except we caused them both. The dust bowl was not worse than this, intense local problems do not out weigh huge dispered ones.
They just make better news.
