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.
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.
Atmospheric carbon dioxide continued its rapid rise in 2019, with the average for May peaking at 414.7 parts per million at NOAA’s Mauna Loa Atmospheric Baseline Observatory, scientists from NOAA and Scripps Institution of Oceanography at the University of California San Diego announced today.
It's not every day you get a message from space. But on May 21, former NOAA employee Christina Koch greeted attendees at NOAA's 47th Global Monitoring Annual Conference from the International Space Station.
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.
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?
The fall equinox means the end of summer for the Northern Hemisphere, but marks the beginning of spring — and the first glimpse of the sun since March — for scientists at NOAA’s South Pole Atmospheric Baseline Observatory located at the Amundsen-Scott South Pole Research Station.
An airborne project with NOAA and CIRES instrument investigators in the Global Monitoring Division was selected for five-year funding starting in 2020 through 2025 from the NASA Earth Venture Suborbital-3 program (EVS-3).
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 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.
