Wildfires in the U.S. have gotten larger, more frequent and more widespread since 2000, according to a new University of Colorado Boulder study published in Science Advances. Researchers, who said they were worried climate change caused more extreme fire events, looked at fire data from the past several decades.
The researchers studied records from around 28,000 fires starting in 1984 and ending in 2018, combining satellite imagery and state and federal fire history records. The team found that there were more fires in the past 13 years than in the previous two decades. On the West and East coasts, fire frequency nearly doubled. In the Great Plains, fire frequency quadrupled.
When they took a closer look at the most extreme wildfires in each region of the country, scientists found that in the West and the Great Plains, the average area burned per wildfire increased in the 2000s.
