A new study finds that tornado activity is generally shifting eastward to areas just east of the Mississippi River that are more vulnerable such as Mississippi, Arkansas and Tennessee. And it's going down in Oklahoma, Kansas and Texas. (AP Photo/Danny Johnston, File)

In future sweltering years with a double whammy of heat and drought, losses of barley yield can be as much as 17 percent, computer simulations show. And that means “beer prices would, on average, double,” even adjusting for inflation, said a study published in the journal Nature Plants on Wednesday, Oct. 17, 2018. (AP Photo/Michael Conroy)
