Global warming is tipping scales toward more wildfires
23 June 2016 (Climate Central) – The 2016 wildfire season has barely begun and dozens of large wildfires have already raged through Western states, with hundreds of thousands of acres burned. This comes on the heels of a 2015 wildfire season that was the worst on record in the U.S., with more than 10 million acres burned.
These are not just random events. Climate change is producing conditions ripe for wildfires, tipping the scales in favor of the dramatic increases in large wildfires we have seen across the West since the 1970s. Snowpack is melting earlier as winter and spring temperatures rise, and in most states an increasing percentage of winter precipitation is falling as rain, meaning there is often less snowpack to begin with. Summer temperatures are rising, particularly in Southwestern states, where the number of extremely hot days is steadily increasing, creating more days where forests and grasslands are dried out and ready to burn.
In 2015, far below-average snowpack in California and the Pacific Northwest created exceptionally dry conditions across the West, and the region experienced fires of a size rarely seen. Washington’s Okanogan Complex fire was the largest group of fires on record for the state. And multiple years of searing drought in California contributed to several fires that were among the state’s top 10 most destructive fires on record.
A Climate Central analysis of 45 years of U.S. Forest Service records from the western U.S. show that the number of large fires on Forest Service land is increasing dramatically. The area burned by these fires is also growing at an alarming rate. [more]
