Forest's death brings higher temps, researchers suspect http://apocadocs.com/s.pl?1256142447
Forests of dead beetle-kill could be speeding regional climate change, increasing temperatures and decreasing rainfalls across the American West.... [Tony] Tezak has watched in horror the past three years as mountain pine beetles have infested an estimated 900,000 acres of lodgepole pines in the forest. "The threat shows no signs of abating," he said. The infestation turns the pine needles brittle and leaves the dead trees pockmarked with hundreds of tiny boreholes where the beetles tunneled in to lay eggs and eat the moist inner bark. Tezak estimates more than a third of the national forest's 3 million trees could be dead by the time the current outbreak subsides. But there might be a more consequential impact to the carnage: The beetle kill could be accelerating regional climate change by increasing temperatures and decreasing rainfalls in Colorado, Wyoming and northern New Mexico.
