Study finds fossil fuel methane emissions greater than previously estimated

But energy development is not responsible for global methane uptick

Methane emissions from fossil fuel development around the world are up to 60 percent greater than estimated by previous studies, according to new research led by scientists from NOAA and CIRES. The study found that fossil fuel activities contribute between 132 million and 165 million tons of the 623 million tons of methane emitted by all sources every year. That’s about 20 to 25 percent of total global methane emissions, and 20 to 60 percent more than previous studies estimated.


As Alaska warms, methane emissions appear stable

Fate of carbon stored in permafrost remains subject of intense research

Analysis of nearly three decades of air samples from Alaska’s North Slope shows little change in long-term methane emissions despite significant Arctic warming over that time period, according to new research published in Geophysical Research Letters.

The Bakken oil and gas field is leaking a lot of methane, but less than some satellites report, and less than the latest Environmental Protection Agency inventory for petroleum systems, according to the researchers’ calculations. That's the finding of the first field study measuring emissions of this potent greenhouse gas from the Bakken, which spans parts of North Dakota and Montana. The work was published today in the Journal of Geophysical Research: Atmospheres

Scientists probe methane mystery in Four Corners

Satellite pinpointed methane emission hotspot in remote region

A team of scientific investigators is now in the Four Corners region of the U.S. Southwest, aiming to uncover reasons for a mysterious methane hotspot detected from space by a European satellite. The joint project is working to solve the mystery from the air, on the ground, and with mobile laboratories.

NOAA and CIRES lead airborne field campaign to look at climate and air quality impacts

Vast regions west of the Mississippi River are under development for oil and gas extraction, and the associated equipment has become a familiar sight on any cross-country road trip or flight.  But while one focus is on what comes out of the ground, NOAA and the Cooperative Institute for Research in Environmental Sciences (CIRES) researchers and their colleagues are studying what escapes to the air—and how it is transformed in the atmosphere and affects air quality and climate.  The scientists are using a suite of state-of-the-art chemical instruments aboard a research aircraft this spring in the NOAA-led Shale Oil and Natural Gas Nexus (SONGNEX 2015) field campaign, to study the atmospheric effects of energy production in the western United States.
