A cloud of methane gas about the size of Delaware was detected over the Four Corners area of the American southwest years ago. The readings were so unusually high that NASA scientists dismissed them. A new study confirms the methane hotspot is real...
The source of the methane is believed to be extensive coal-mining activity in the San Juan Basin, according to Eric Kort, a professor of Atmospheric, Oceanic and Space Sciences at the University of Michigan in Ann Arbor and lead author of the study. He calls the Basin “the most active coalbed methane production area in the country.”
The study shows that there were 0.59 million metric tons of methane released every year during the period 2003-2009, 3.5 times more than earlier estimates.
