Even as the Wallow fire threatens to alter the Arizona landscape for a long time to come, some scientists say climate change may be fueling a trend toward larger wildfires in the American West.

A wildfire in Arizona that has blackened an area half the size of Rhode Island, prompted the evacuation of some 2,000 people in its path, and is threatening long-distance power lines that serve New Mexico and Texas, is the latest poster child for what some scientists see as a long-term trend toward larger, longer-lived wildfires in the American West.
And as researchers explore the causes, climate change appears to be an important contributor.
Nor is Arizona, which is battling three major blazes, alone in watching significant acreage go up in smoke this year.

In Texas, whose fire season officially starts each Nov. 15, wildfires have already consumed a record 2.8 million acres this season, according to the state's Forest Service. That eclipses by far the record set during the 2006 fire season, when wildfires burned nearly 2 million acres.
In Florida, firefighters are working to douse 35 wildfires larger than 100 acres, the largest of which has burned just over 160,000 acres near the Florida-Georgia border.
