Man didn't cause the drought.
Glad to enlighten you.
WHAT THE FUCK ARE YOU TALKING ABOUT?
Way to try and bolster your argument by taking a stance on something that NOBODY IS FUCKING ARGUING WITH. No shit man didn't cause the drought in the 1930's. They removed all the deep rooted grasses that kept the topsoil in place. You know that beautiful thing that wind does in the midwest where it blows through the grasses and it's like waves in the sea? It didn't do that because they poorly farmed the area and all that topsoil just went byebye.
Dust storms made worse by bad agricultural or grazing techniques aren't climate, drought is.
Yes, it was a climate phenomenon, caused by man.
Modeling the Dust Bowl Climate Forcings
By Benjamin Cook June 2008
Recurrent periods of drought are a common feature of North American climate, often the result of colder than normal sea surface temperatures (SSTs) in the eastern tropical Pacific (so-called La Niña conditions). One such drought, the "Dust Bowl" of the 1930s, resulted in widespread crop failure, dust storms, and the displacement of thousands of people.
The Dust Bowl drought was atypical for a North American drought in many ways, most notably the fact that it was centered over the Great Plains rather than in the southwest and was accompanied by large scale dust storms that were unprecedented in the historical record. The dust storms themselves resulted from a combination of dry conditions, poor land use practices, and large scale crop failures that exposed easily erodible bare soil to the strong winds of the Great Plains. Many climate models, however, have difficulty reproducing the precipitation pattern of the Dust Bowl drought using SSTs alone. Could the dust storms themselves explain the anomalous drought?
