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.

Global carbon dioxide growth in 2018 reached 4th highest on record
By the end of 2018, NOAA’s atmospheric observatory at Mauna Loa recorded the fourth-highest annual growth in the concentration of atmospheric carbon dioxide (CO2) in 60 years of record-keeping.

Study sheds light on persistent gap in natural gas methane emissions measurements
It’s a question that’s puzzled policymakers, researchers and regulatory agencies for years: How much methane is being emitted from natural gas operations across the U.S.? And why have the two main estimation methods applied across U.S. oil and gas basins always seem to disagree?

Another climate milestone on Mauna Loa
Carbon dioxide levels measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory averaged more than 410 parts per million in April and May, the highest monthly averages ever recorded, scientists from NOAA and Scripps Institution of Oceanography at the University of California San Diego announced today.

NOAA’s greenhouse gas index up 41 percent since 1990
NOAA’s Annual Greenhouse Gas Index, which tracks the warming influence of long-lived greenhouse gases, has increased by 41 percent from 1990 to 2017, up 1 percent from 2016 -- with most of that attributable to rising carbon dioxide levels.
