President Biden has approved a major disaster declaration for parts of Northern California to help areas devastated by the climate-fueled Dixie and River fires. Over 1.5 million acres of land have burned so far this year in California, and the number is growing as the Caldor Fire is less than 10% contained. It is now threatening communities near Lake Tahoe. Air quality alerts linked to smoke from the wildfires have been issued in seven states: California, Nevada, Oregon, Colorado, Wyoming, Montana and Idaho. Residents of Reno, Nevada, are being urged to stay home with their windows closed, because the air is so unsafe to breathe. Meanwhile, in Minnesota, more than 400 firefighters are battling a large blaze near the Canadian border. One official compared the Greenwood Fire to a freight train, saying, “Once it starts rolling, it starts to build up steam and feed off itself.”
