EarthSky reported recently that 2015 was the worst year on record for wildfires in the United States, based on area covered.  Estimates by the National Interagency Fire Center were that more than 10 million acres burned.  Many of those were in the western US, which has been plagued by severe drought and high temperatures this year.  You can read the story here.  The final report on the 2015 season will be released later this spring.
