Scientists in the Global Monitoring Laboratory released NOAA’s latest global atmospheric methane assimilation/flux inversion system, CarbonTracker-CH4 2023.
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.
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.
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?
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.
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.
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.
GML and CIRES researchers are presenting several talks and posters, and collaborating on others, at the 2023 Annual Meeting of the American Meteorological Society.
GML and CIRES researchers are presenting several talks and posters at the 2022 Fall Meeting of the American Geophysical Union, and collaborating on many more.
Carbon dioxide measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory peaked for 2022 at 421 parts per million in May, pushing the atmosphere further into territory not seen for millions of years.
Greenhouse gas pollution caused by human activities trapped 49% more heat in the atmosphere in 2021 than they did in 1990, according to NOAA scientists.
NOAA Global Monitoring Laboratory has recently obtained approval from the FAA to fly the High-altitude Operational Returning Unmanned System (HORUS) up to 90,000 ft above mean sea level in the national airspace in northeastern Colorado.
For the second year in a row, NOAA scientists observed a record annual increase in atmospheric levels of methane, a powerful, heat-trapping greenhouse gas that’s the second biggest contributor to human-caused global warming after carbon dioxide.
