California Forests Now Net Source Of GHGs, Thanks To Fires And Drought
A Californian task force has been handed the confounding task of figuring out how forestry and land management practices could be improved to prevent what scientists say are surprisingly high levels of climate pollution escaping from its forests and other wildlands. A new study has shown that greenhouse gases are billowing out of the states forests faster than they are being sucked back in, with unnaturally intense wildfires mostly to blame.
Ecosystems are regrowing, but not fast enough, Patrick Gonzalez, a U.S. National Park Service climate change scientist involved with the research, said. The losses are outpacing the growth. The key element here is wildfire.
From 2001 through 2010, the states wildlands were responsible for about 8 million tons of carbon pollution annually more climate pollution than is released every year by the entire economy of Vermont.
That was the conclusion of a sophisticated analysis requested and partly funded by Californias air resources board. Wildfires affecting a small portion of the state were responsible for two-thirds of the estimated losses of carbon from what had been living plants.
