More and bigger fires. Dirtier air. Poor visibility in national parks including Yellowstone and Glacier. As the climate warms over the next four decades, portions of Wyoming and Montana are at ground zero for larger areas burned by wildland fires and an increase in air pollution from those fires, writes Brett French in the Casper Star-Tribune. The grim prediction is found in a study recently released by the Harvard School of Enginering and Applied Sciences and conducted for the EPA.
