Ranchers in Divide County, North Dakota, rely on the rain. But last year the rains failed, and the temperature shot up in a severe and sudden flash drought. “The crops just didn’t come out of the ground,” said one resident. What happened? How had it happened so fast? And would it happen again? “Belief” in climate change falls mostly along party lines here, and for many ranchers in the county the Earth’s warming had nothing to do it.
