Climate change may give a big boost to dairy farming in the Midwest, including Michigan and northern Wisconsin, a new study of the future for U.S. dairy farms reports. "Dairy production in North America will shift to areas with sufficient rainfall and adequate growing seasons, primarily migrating from the West and Southwest to Great Lakes regions and into the Canadian prairies," according to Jack Britt, a former Michigan State University professor and now a North Carolina-based industry consultant."Dairy farms will relocate to regions that have ample rainfall and suitable climates," he said in a recent study that looks at dairy farming in 2067.
