A round-up of the top climate and energy news.
Researchers at the Yale School of Forestry & Environmental Studies say some diseased trees release methane at a level that may be a globally significant source of the potent heat-trapping gas, according to the study published in Geophysical Research Letters. [Summit County Citizens Voice]
Sixty trees sampled at Yale Myers Forest in northeastern Connecticut contained concentrations of methane that were as high as 80,000 times ambient levels. Normal air concentrations are less than 2 parts per million, but the Yale researchers found average levels of 15,000 parts per million inside trees.
“These are flammable concentrations,” said Kristofer Covey, the study’s lead author and a Ph.D. candidate at Yale. “Because the conditions thought to be driving this process are common throughout the world’s forests, we believe we have found a globally significant new source of this potent greenhouse gas.”
