The release of the power plant rules coincide with a reminder of global warming’s impact in California, where about two dozen wildfires are raging amid a historic drought. Thousands of people have been evacuated, and a firefighter has been killed. Daniel Berlant, spokesperson for the California Department of Forestry and Fire Protection, said the largest of the blazes, the Rocky Fire, consumed an unprecedented 20,000 acres over a five-hour period Saturday night.

Daniel Berlant: “That fire grew 20,000 acres in a five-hour period last night. That is an unbelievable amount of acreage burned in such a short amount of time. But again, it’s because of these drought conditions that are allowing fires like that one and like all the others that we’re responding to to grow so quickly.”
