A cool October broke a 16-month streak of above average temperatures across the Lower 48, but temperatures are projected to remain above normal across most of the western half of the country in the coming months. In addition, the latest climate change projections put future temperature gains on the high side of various models.
To Katharine Hayhoe, professor and director of the Climate Science Center at Texas Tech University in Lubbock, this heralds big changes for agriculture on the Great Plains. “In a nutshell,” Hayhoe says, “we’re seeing major shifts in places and times we can plant, the types of crops we can grow and the pests and diseases we’re dealing with. If you talk to seed companies, the U.S. Department of Agriculture (USDA) and even farmers, they tell you we can modify our way out of this, that we can overcome all these problems with technology. There’s no question we can adapt to some of the change, but whether we can adapt to all of it is a very open question.”
