Inside Climate News: A 2016 study by researchers at Harvard, Yale and Colorado State University, predicts that, over six years around 2050, 82 million people in the West will endure more “smoke waves,” which they define as two or more days of heavy wildfire emissions, with smoke that will be both thicker and longer-lasting than today. Other Colorado State research shows the number of U.S. residents dying annually as a result of exposure to wildfire smoke could more than double, to 40,000, by the end of this century.
