Anderson, Marshall Ellis, Carol D. Singer, Michael B. Using the resulting statistical patterns, Westerling and his coauthors projected how climate change would affect Greater Yellowstone fires through the year It has burned this way about every to years, for thousands of years," said coauthor Monica Turner, the Eugene P.
In the researchers' simulations, years with no large fires -- very common in the recent past -- become extremely rare by and are all but eliminated after The projections show that after , the average annual area burned is about , hectares, or nearly square miles.

By , the average yearly burn exceeds that of the historic season of , when fires claimed more than 1, square miles. Westerling cautioned, though, that the models used in the study will not work once the increase in fires creates a fundamental change in the ecosystem.
As the landscape changes, the relationships between climate and fire would change as well. Westerling and his coauthors said warming alone is likely to lead to a decline in suitable habitat for tree species currently found in greater Yellowstone, and the projected increase in frequency and severity of wildfires could accelerate that process to a tipping point at which the trees may no longer regenerate.
This could cause some forested areas to be converted to woodland or non-forest, and similar changes might be expected in other subalpine or boreal forests. Because of its pristine condition, Yellowstone provides an unparalleled natural laboratory to monitor and learn from fire and ecosystem responses to climate change.
