US Methane “Hotspot” is Snapshot of Local Pollution

A giant methane cloud caught by satellite in 2014 looming over the U.S. Southwest wasn’t a persistent hotspot, as first thought. Instead, the methane cloud was the nightly build-up of polluted air that trapped emissions of the potent greenhouse gas near the ground, according to a new CIRES- and NOAA-led study.

Lawns provide surprising contribution to L.A. Basin’s carbon emissions

The Los Angeles Basin is often thought of as a dry, smoggy, overdeveloped landscape. But a new study led by NOAA and the University of Colorado, Boulder shows that the manicured lawns, emerald golf courses and trees of America’s second-largest city have a surprisingly large influence on the city’s carbon emissions.

Tracking fossil fuel emissions with carbon-14

Researchers from NOAA and the University of Colorado Boulder have devised a breakthrough method for estimating national emissions of carbon dioxide from fossil fuels using ambient air samples and a well-known isotope of carbon that scientists have relied on for decades to date archaeological sites.

Airborne research shows East Coast cities emitting twice as much methane as estimated

A new NOAA and University of Michigan study using an instrumented airplane has found unexpectedly large emissions over five major cities along the East Coast - twice the total amount of methane and almost 10 times the amount estimated from natural gas.

Surprisingly large carbon uptake by North American biosphere during El Niños

New analysis of NOAA’s long-term air samples by NOAA and CIRES scientists finds that the North American terrestrial biosphere takes up unexpectedly large amounts of carbon in response to elevated carbon dioxide levels during El Niño years.

US methane emissions flat since 2006 despite increased oil and gas activity: study

Natural gas production in the United States has increased 46 percent since 2006, but there has been no significant increase of total US methane emissions and only a modest increase from oil and gas activity, according to a new NOAA study.
