Daniel Swain in The Washington Post: California’s rainy season now starts nearly a month later, increasing wildfire risks

A long-expected consequence of global warming has come to fruition, a study finds: California’s rainy season is starting later in the year than it used to, extending the threat of fast-spreading wildfires into the cooler months when, in earlier decades, the fire season would have been over, according to a new study.  According to Daniel Swain, a climate scientist at the University of California at Los Angeles, who was not involved in the new study, the research convincingly shows that this seasonal sharpening is already happening, which a growing body of climate model studies say should be occurring as greenhouse gases build up in the air from the burning of fossil fuels for energy, among other human activities.
