A new study on atmospheric methane causes and increases over the last twenty years is due out in this Septembers American Geophysical Union’s Geophysical Research Letters. The study looks specifically at the causes driving atmospheric methane increases, which grew in 2007 and 2008 after a ten-year static, near zero growth period. Methane is a secondary greenhouse gas after Carbon Dioxide, although not as critical to global warming effects. Scientists from NOAA and others analyzed recorded measurements from 1983 to 2008 from air samples collected weekly at 46 surface locations around the world to study the increase:
“At least three factors likely contributed to the methane increase,” said Ed Dlugokencky, a methane expert at NOAA’s Earth System Research Laboratory in Boulder, Colo. “It was very warm in the Arctic, there was some tropical forest burning, and there was increased rain in Indonesia and the Amazon.”
This report comes on the heels of recent worries about Global Warming from the Copenhagen talks, Energy and Nuclear Energy Companies leaving the U.S. Chamber of commerce in a temper tantrum over energy policy, recent tsunami and earthquake activity, and general scientific 4-degree rises and unscientific doomsayers. We’ll stick with the (real) scientists on this one.
