Dust bowl conditions of 1930s US now more than twice as likely to reoccur

Climate breakdown means conditions that wrought devastation across Great Plains could return to region

The agricultural conditions known as a dust bowl", which helped propel mass migration among drought-stricken farmers in the US during the great depression of the 1930s, are now more than twice as likely to reoccur in the region, because of climate breakdown, new research has found.

Dust bowl conditions in the 1930s wrought devastation across the US agricultural heartlands of the Great Plains, which run through the middle of the continental US stretching from Montana to Texas. The conditions are caused by a combination of heatwaves, drought and farming practices, replacing the native prairie vegetation.
