Climate Central: A new study of the air above a natural gas field in Utah suggests that far more methane gas may be escaping into the atmosphere from drilling operations than previously estimated. The study, to be published in the journal Geophysical Research Letters, is the first to use an aircraft to directly sample the air downwind of natural gas and oil wells in order to calculate emissions of methane and contributors to smog. Most other studies to date have relied on various estimating techniques to determine...
