More Words, Deeper Hole

Is this a case of context being for the weak? Why do climate change deniers need to have a position on the Dust Bowl? It's not like droughts were unheard of before the twentieth century, or before the industrial period. Is there current speculation that the drought of the 30s was human-caused in some way?

The story I first learned about the Dust Bowl, back in the days when (almost) nobody was talking about greenhouse gases or anthropogenic climate change was that there was a drought in the 30s, the agricultural effects of which were made worse by poor farming practices that led to accelerated soil erosion. Is that controversial?
