The Dust Bowl was an environmental disaster that hit the Midwest in the 1930s due to a severe drought and harsh farming techniques. It affected southeastern Colorado, southwest Kansas, the panhandles of Oklahoma and Texas. Changes in weather patterns over the Atlantic and Pacific oceans in 1930 weakened the jet stream, preventing rain from reaching the Great Plains. This caused massive dust storms that forced many farmers out of business, costing them their livelihoods and homes during the Depression era.
