Everyone has heard of the Dust Bowl, but understanding its true devastation is difficult. In the midst of the Great Depression, crops began to die and the dust began to fly. The four droughts of the 1930s crippled the country, lengthening the depression and causing the single greatest migration of people the US has ever seen.
A new study from NASA and the Lamont-Doherty Earth Observatory has revealed that the drought of 1934 was not only the worst of the Dust Bowl, but the worst drought felt worldwide in the last 1,000 years. The findings were published in an upcoming issue of Geophysical Research Letters.
