NOAA science expertise and data has supported the U.S. government decision to reduce potent greenhouse gas emissions. On September 21st, the United States Senate successfully approved the Kigali Amendment of the Montreal Protocol with strong bipartisan support. The Kigali Amendment, negotiated under the Obama administration in 2016, is an international agreement to phase-out and replace hydrofluorocarbons, a class of chemicals that act as potent greenhouse gasses.
An annual analysis of air samples collected at remote sites around the globe that is tracking a continued decline in the atmospheric concentration of ozone-depleting substances shows the threat to the ozone layer receding below a significant milestone in 2022, NOAA scientists have announced.
A research team led by scientists from the University of California Berkeley and NOAA found that HRRR-Smoke accurately predicted the intensification of smoke pollution from the Camp Fire.
Scientists from NOAA and The Aerospace Corp. modeled the climate response of the stratosphere to increased future emissions of black carbon from rockets burning kerosene fuel.
New research published in Atmospheric Chemistry and Physics projects future emissions of hydrofluorocarbons (HFCs), a class of potent greenhouse gasses, based on recent trends and compliance with current policies. The ability to observe trends of these compounds in the atmosphere is made possible by the long-term record of observations produced by the Halocarbons and other Atmospheric Trace Species (HATS) Division within NOAA’s Global Monitoring Laboratory.
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, scientists from NOAA and Scripps Institution of Oceanography at the University of California San Diego announced today.
New research has identified two additional regions of Asia as contributing to rising emissions of the ozone-destroying chemical CFC-11 identified by NOAA scientists in 2018.
On December 30, 2021, a combination of long-term drought and hurricane-force winds set the stage for what would become the most destructive fire in Colorado history in terms of property loss.
When Super Bowl LVI kicks off at the SoFi Stadium in Los Angeles on February 13, a nearby command center operated by emergency managers will include NOAA experts.
Scientists are traveling to La Reunion to intercept the plume from the Tonga volcano eruption.
Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
