CORRECTION (Jan. 8, 2020, 6:05 p.m. ET): An earlier version of the interactive map displaying the aggregate size of the wildfires misrepresented their size. The radius of the circle representing the wildfires should be 101 miles, not 57 miles. In addition a map miscalculated the size of Australia's wildfires compared to a U.S. city, and a graphic incorrectly showed the size of the Amazon rainforest fires and the 2019 California fires. The map and the graphic have been fixed.
