12 October 2012 (PhysOrg) – A new pan-European study suggests that the economic value of forests will decline between 14% and 50% due to climate change. If measures are not taken to change this, the damage could reach several hundred billion euros, say researchers led by the Swiss Federal Institute for Forest, Snow and Landscape […]

During the past 40 years, wildfires have started earlier in the year and have continued to burn later in the year, lengthening the overall “burn season.” This figure illustrates the start date of the first wildfire each year on USFS land and the start date of the last recorded fire. The inset shows how the […]
When we compared the average annual spring and summer (March-August) temperatures to the number of large wildfires burning across all 11 Western states, we observed a relationship similar to that reported by Westerling, et al.; years with higher-than-average spring and summer temperatures also tended to be years with more large fires. Seasonal temperatures are a […]
Among the Western States, Arizona, California, Colorado, Idaho, and Montana have seen the most dramatic increases in wildfires since 1970. According to our analysis, the average annual number of large fires has nearly quadrupled in Arizona and Idaho, and at least doubled in California, Colorado, Montana, New Mexico, Nevada, Oregon, Utah, and Wyoming. On the […]
