A new study out of the University of Washington takes a look at the effects of climate change on milk-per-cow production figures in certain areas of the United States.

Projecting the change in nationwide milk production out to the year 2080, researchers say the Southwestern part of the United States may become inhospitable for cows. For example, cows in Maricopa, Ariz., could be producing as little as half the milk they currently produce by that time. And overall, the nation will be producing an average of 6 percent less milk in 2080 than today, they estimate.

That could mean an annual loss of more than $100 million a year in places like Tulare, Calif., the researchers note.
