U.S. Climate-Changing Emissions Drastically Underestimated

Living on Earth
Measuring the emissions of the powerful climate-changing gas methane emissions is difficult, as it escapes from wetlands and landfills as well as from oil and gas drilling and pipelines around the world. Now, a team of scientists using satellite data with ground observations has found a better way to calculate its presence. Daniel Jacob, Harvard professor of Atmospheric Chemistry and Environmental Engineering, tells host Steve Curwood their recent study suggests much more methane is escaping than estimates had calculated, and the US could be responsible for up to 60 percent of the extra.
