Today, people debate to what extent human activity is responsible for global warming. Historians and atmospheric scientists have an incredibly similar argument with a different defining event. A comprehensive report by Robert McLeman synthesizes scientific finding and contentions to better estimate the extent human activity is responsible for the Dust Bowl.
McLeman and his team concluded that, although human activity certainly exacerbated the Dust Bowl, it was in no way a causal event. This position is supported by paleo-studies that indicate the drought and dust storms of the “Dirty Thirties” were of shorter duration and less severe than the mega droughts of the sixth to thirteenth centuries where large-scale agricultural settlement had obviously not taken place. Further, there are historical reports of violent dust storms in the southern Great Plains that date back to the 1830’s. Yet, the article does acknowledge that the farmland-grassland ratio of Oklahoma and Texas increased from 1:3 to 1:2 from 1920-1930 after WWI triggered commodity prices to rise, an entrepreneurial farming rush, and tractors gained prominence.

The 1936 report from the Great Plains Committee placed emphasis on human error and land exploitation instead of considering the phenomena as a natural occurrence for the land. Thus, the committee’s recommendations of federal and state agricultural intervention make sense with that perspective. Yet, the committee’s comprehension could be seen as an example of humans trying to understand and organize a world that is often inherently random. Psychologically, it also is stands as testament to the fact that humans want to be able to point and blame something or someone when things are rough.

McLeman ends his analysis of sources by noting that the area of scientific research regarding the Dust Bowl is still rich. With new evidence discovered and technological advancements, now dominant perceptions and theories could still change.
It is interesting to consider why exactly people of the past were too quick to blame themselves for climate change, yet today, even with more scientific evidence, people adamantly deny that they climate is changing due to their actions. It’s as if history has over-corrected.
