Irrigation units are pictured in southwest Kansas near Dodge City, Kansas, November 26, 2012. Residents of the Great Plains over the last year or so have experienced storms reminiscent of the 1930s Dust Bowl. Experts say the new storms have been brought on by a combination of historic drought, a dwindling Ogallala Aquifer underground water supply, climate change and government farm programs.
