Twenty of the nation’s top climate scientists have sent a letter to Gov. Jerry Brown, telling him that his plans supporting increased use of the controversial practice of hydraulic fracturing, or “fracking,” will increase pollution and run counter to his efforts to cut California’s global warming emissions.

The letter is the latest example of the increased pressure that environmentalists and others concerned about climate change have been putting on Brown in recent months. Their argument: The governor can’t say he wants to reduce global warming while expanding fossil fuel development in California.
