Wildfires in the Western U.S. Becoming Larger and More Intense Despite Fewer Starts
Wildfires in the Western U.S. Becoming Larger and More Intense Despite Fewer Starts
US · Published Jun 5, 2026
Recent research highlights a paradox in wildfire trends across the Western United States.
While the total number of wildfires has decreased by 31% between 1992 and 2020, the acreage burned has increased by 40%, according to a study led by Amirhossein Montazeri, a PhD student at Boise State University.

Why It's Important?

The increasing intensity and size of wildfires pose significant risks to ecosystems, communities, and infrastructure across the Western U.S. Larger fires can lead to more extensive damage, higher suppression costs, and greater threats to public safety. The study underscores the role of climate change in exacerbating fire conditions, with warmer and drier weather creating an environment where fires can grow rapidly. Additionally, the shift toward fewer but larger fires may challenge existing firefighting resources and strategies, requiring more targeted and adaptive approaches to fire management.
