Despite pandemic shutdowns, carbon dioxide and methane surged in 2020

Levels of the two most important anthropogenic greenhouse gases, carbon dioxide and methane, continued their unrelenting rise in 2020 despite the economic slowdown caused by the coronavirus pandemic response.

Women’s History Month: A conversation with NOAA Corps Officer LTJG Marisa about her 13 months “on the ice”

In honor of Women’s History Month, Global Monitoring Laboratory (GML) is highlighting some of the great work done by our scientists. Today’s story expands on a previous one introducing a day in the life at the South Pole for NOAA Corps Officer Lieutenant Junior Grade Marisa Gedney, who served as a Station Officer at the Amundsen-Scott South Pole Station in Antarctica.

COVID-19 Lockdowns Reduced Ozone Pollution Over the Northern Hemisphere

During COVID-19 shutdowns last year, ozone levels in the lower atmosphere fell by seven percent across much of the Northern Hemisphere, according to a new study.

Emissions of a banned ozone-depleting gas are back on the decline

Five years after an unexpected spike in emissions of the banned ozone-depleting chemical chlorofluorocarbon CFC-11, emissions dropped sharply between 2018 and 2019, new analyses of global air measurements show.

Large, deep Antarctic ozone hole to persist into November

Persistent cold temperatures and strong circumpolar winds supported the formation of a large and deep Antarctic ozone hole that will persist into November, NOAA and NASA scientists reported today.

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.

NOAA marks 40 years of ballon-borne water vapor measurements

In April 2020, the Global Monitoring Laboratory’s measurement record of upper atmospheric water vapor over Boulder, Colorado, surpassed 40 years in length.

Warming influence of greenhouse gases continues to rise, NOAA finds

Record high levels of greenhouse gas pollution continued to increase the heat trapped in the atmosphere in 2019, according to an annual analysis released by NOAA scientists.
