Shrouded by smoke from a fire in California’s parched San Bernardino Mountains, schools in the Victor Valley closed their doors earlier this month. The Pilot Fire was contained on Monday — shortly before the Blue Cut Fire broke out, billowing soot and ash over the valley afresh, forcing further closures. Researchers have taken to using the term “smoke wave” to describe the type of multiday impacts from wildfire pollution that were experienced this month in the Victor Valley. The valley contains hundreds of thousands of residents as well as the thoroughfare linking Las Vegas with Los Angeles.
scientists from Yale and Harvard calculated that 82 million residents of the West will experience smoke waves that are two days or longer during a six-year period beginning in the late 2040s. That’s a 44 percent increase from a six-year period last decade.
