Warming Climate Plays Large Role in Western U.S. Wildfires





In the most systematic analysis to date of recent changes in forest fire activity, Anthony Westerling, Hugo Hidalgo and Dan Cayan of Scripps Oceanography, along with Tom Swetnam of the University of Arizona, compiled a database of recent large western wildfires since 1970 and compared it with climate and land-surface data from the region. The results show that large wildfire activity increased "suddenly and dramatically" in the 1980s with longer wildfire seasons and an increased number and more potent wildfires.

The new findings, published in the July 6 issue of Science Express (the advance online version of the printed journal Science), point to climate change, not fire suppression policies and forest accumulation, as the primary driver of recent increases in large forest fires.

Not sure where you live, but here in the west, environmentalists have made it practically impossible to clear out the forests which is resulting in increased fires. You can find just as many scientists that would back that up as you would that agree with your comments, first hand experience tells me different. It is logical to clear out the undergrowth and deadwood, especially after the heavy rains we experienced this year in California. It is a disaster waiting to happen.

I should point out that they're not "my" comments; I merely found the article worthy of interest. I would be cheered indeed if the fires are merely caused by environmentalists acting irresponsibly.
