Abstract :
Methane emissions from oil and gas extraction, herding livestock, and other human activities in the United States are likely 25 to 75 percent higher than the U.S. Environmental Protection Agency currently recognizes, according to a meta-analysis of methane emissions research published recently in Science. While experts in remote sensing debate the merits of this and other recent challenges to the EPA´s numbers, definitive answers are already on order via a high-precision Earth observation satellite to be launched next year.
