A fire in South Lake Tahoe, which began Sunday, has destroyed 2,700 acres of woods and 275 homes. Lake Tahoe’s gorgeous blue waters are sprinkled with ashes. The blaze is just 40 percent contained at present, but firefighters expect to have it fully contained by Sunday. The Los Angeles Times called the fire “one of the most destructive in memory.” And California isn’t in the clear yet: Low rainfall combined with the hotter temperatures brought by climate change have intensified the state’s already menacing susceptibility to wildfire.
