The North American monsoon has dictated the length of wildfire season for centuries in the U.S.-Mexico border region, according to new University of Arizona research that can inform land management amid global climate change.
But this year was anything but normal. The 2020 monsoon season was the second-driest on record, and many high-profile wildfires swept across the Sonoran Desert and surrounding sky islands. Putting an end to severe fires may only become harder as climate change makes monsoon storms less frequent and more extreme, say the authors of a new study published in the International Journal of Wildland Fire.
The U.S. may be able to learn from Mexico’s wildfire management strategy, the researchers say.
“These large fire years are the result of many factors, but fire weather and seasonal climate loom very large in the picture. In the case of (Tucson’s) Bighorn Fire (this summer), for example, we had
