The amount of carbon dioxide (CO2) being released from tundra in the northern region of Alaska during early winter has increased 70 percent since 1975, according to a new regional climate paper by scientists participating in a research project funded by NOAA and NASA.

NOAA/ESRL scientists and their colleagues at the University of East Anglia, Utrecht University, and NCAR calculated an atmospheric lifetime of the trace gas, sulfur hexafluoride (SF6), based on measurements in the polar stratospheric vortex and modeled transport into the stratosphere.

What started out as a modest research project driven by scientific curiosity provided the agency that would later become NOAA with some of the first insights into how ozone was distributed in the atmosphere.

A trace gas present in the atmosphere in miniscule amounts is helping scientists answer one of the biggest questions out there: Has plant growth increased alongside rising levels of carbon dioxide in the atmosphere?

A new NOAA study shows that methane emissions from the United States did not grow significantly from 2000 to 2013 and are not likely to have been an important driver of the increase in atmospheric methane levels observed worldwide after 2007, as other studies have suggested.

Carbon dioxide levels measured at NOAA’s Mauna Loa Baseline Atmospheric Observatory rose by 3 parts per million to 405.1 parts per million (ppm) in 2016, an increase that matched the record jump observed in 2015.

As winter closes in, flights to the international research compound are suspended for the long Antarctic winter.

As station chief at NOAA’s Point Barrow, Alaska, observatory, Bryan Thomas works close to the edge of the Arctic Ocean. What he saw from his office in early February, looking north toward the horizon, was troubling.

The hole in the Earth’s ozone layer that forms over Antarctica each September grew to about 8.9 million square miles in 2016 before starting to recover, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA) who monitor the annual phenomenon.

To mark the peak of ozone hole season, we’re highlighting four ways that climate and the ozone hole are related—and one important way they aren’t.

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.

Carbon dioxide levels in the Earth’s atmosphere passed a troubling milestone for good this summer, locking in levels of the heat-trapping gas not seen for millions of years.
Every year, the amount of carbon dioxide (CO2) rises during winter and then falls slightly during the Northern Hemisphere’s growing season, as plants take up this greenhouse gas during photosynthesis.
But this year, for the first time since before the Ice Age, CO2 will not fall below 400 ppm.

The NASA Pacific Oxidants, Sulfur, Ice, Dehydration, and cONvection (POSIDON) Experiment is a focused airborne science mission to study the ozone distribution, sulfur chemistry, very short-lived ozone depleting species (VSLS), cloud microphysics, and dehydration in the tropical upper troposphere and lower stratosphere over the western Pacific.

Brad Hall, a research scientist in the Global Monitoring Division of NOAA/ESRL, has been named a winner of the 2016 Governor's Award for High-Impact Research for his work on improving existing techniques to make calibration standards and measurements of very low concentrations of greenhouse gases such as carbon dioxide, methane, nitrous oxide and ozone-depleting gases like chlorofluorocarbons.
