Broken record: Atmospheric carbon dioxide levels jump again

Carbon dioxide levels measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory peaked at 424 parts per million in May, continuing a steady climb further into territory not seen for millions of years, scientists from NOAA and Scripps Institution of Oceanography offsite link at the University of California San Diego announced today.

NOAA index tracks how greenhouse gas pollution amplified global warming in 2022

Greenhouse gas pollution from human activity trapped 49 percent more heat in the atmosphere during 2022 than those same gases did in 1990, according to an annual NOAA report. NOAA’s Annual Greenhouse Gas Index, known as the AGGI, tracks increases in the warming influence of heat-trapping gases generated by human activity.

#EarthDay: Invest in our changing planet now to secure a more livable future

Since the first Earth Day, billions across the globe have invested their time, creativity and energy to honor and nurture our home planet. In the decades since April 22, 1970, however, global climate change has had an alarming effect on Earth and its inhabitants. So how is NOAA addressing climate change and other environmental challenges?

Greenhouse gases continued to increase rapidly in 2022

Levels of carbon dioxide (CO2), methane and nitrous oxide, the three greenhouse gases emitted by human activity that are the most significant contributors to climate change, continued their historically high rates of growth in the atmosphere during 2022, according to NOAA scientists.

The Montreal Protocol banned this family of ozone-depleting chemicals. Why are some still increasing?

The Montreal Protocol contained an exception that allowed continued production of some CFCs in the manufacture of other chemicals, including ozone-friendly CFC replacements called hydrofluorocarbons or HFCs. Scientists are now drawing attention to this exception not just because rising emissions of these chemicals potentially complicate recovery of the ozone layer, but because they are also potent greenhouse gases contributing to global warming.

Celebrating Women's History Month 2023 with Aleya Kaushik

To celebrate Women’s History Month, we asked women throughout NOAA Research to share how their work contributes to NOAA’s mission of preparing for a Climate-Ready Nation. This article highlights an interview with Aleya Kaushik, a CIRES research scientist working in the Carbon Cycle Greenhouse Gases group at NOAA’s Global Monitoring Laboratory.

Celebrating Women's History Month 2023 With Sara Morris

To celebrate Women’s History Month, we asked women throughout NOAA Research to share how their work contributes to NOAA’s mission of Climate Resilience and preparing for a Climate-Ready Nation. This article highlights an interview with Sara Morris, a physical scientist and team lead for the Atmospheric Measurement Network under the Observatory Operations Division at NOAA’s Global Monitoring Laboratory (GML).

Vanda Grubišić named director of NOAA Global Monitoring Laboratory

Vanda Grubišić, Ph.D., a research meteorologist and experienced scientific leader, has been named the director of NOAA’s Global Monitoring Laboratory in Boulder, Colorado. Grubišić will join one of the world’s preeminent research institutions for monitoring long-term changes in the atmosphere, including those caused by climate change. She starts on March 27.

Potent greenhouse gas declines in the US, confirming success of control efforts

A new NOAA analysis shows U.S. emissions of the super-potent greenhouse gas sulfur hexafluoride (SF6) have declined between 2007-2018, likely due to successful mitigation efforts by the Environmental Protection Agency (EPA) and the electric power industry.

Having dodged lava flows, NOAA's Mauna Loa research facility to get upgrades

NOAA’s Mauna Loa Atmospheric Baseline Observatory, the benchmark sampling site for monitoring global climate change, is slated to undergo a major renovation and facility upgrade once road access is restored over lava flows produced by the recent eruption of Mauna Loa volcano.
