Firefighters have made progress in the battle against wildfires covering massive areas and leaving a trail of damage in the western United States. The Park Fire in California had scorched an area greater than Los Angeles and was one of more than 100 blazes burning in the U.S. Sunday. Some were sparked by the weather during blistering heat and bone-dry conditions. A man accused of setting the Park Fire is due in court Monday. Firefighters increased containment to 12% on Saturday, aided by cooler temperatures and more humidity. About 2,000 people were ordered to evacuate because of a fire sweeping through Southern California's Sequoia National Forest. Millions of people were under air quality alerts in the northwestern U.S. and western Canada.
