Climate Wildfires Smoke

Heavy smoke from several large wildfires blazing in Canada and Minnesota is expected to engulf large swaths of the Midwest and Northeast U.S. this week, exposing millions of people to dangerous air pollution. Minnesota officials issued an air quality alert from Tuesday through Friday for areas including the Twin Cities metro area, Alexandria and Two Harbors, with very heavy smoke expected across the Arrowhead as large wildfires continued to spread. Officials in Michigan and New York also issued air quality warnings.
