2022 was a busy year for volcanic eruptions with Hawaii's Mauna Loa and Kilaeau erupting simultaneously, along with Mount Semeru, Indonesia and the Hunga undersea volcano in Tonga. While the United States Geological Survey is the primary agency that monitors volcanic activity in the United States, the National Oceanic and Atmospheric Administration (NOAA) oversees safety systems for tsunamis and other volcano-related threats, as well as studies the impact of volcanic gasses on our global climate.
The Annual Greenhouse Gas Index serves as a measure of global society's progress - or lack of progress - in reducing greenhouse gas emissions.
A new study published this week in the journal Science estimates the Southern Ocean absorbs 550 million tonnes of carbon from the atmosphere per year, confirming its role as a significant carbon sink.
NOAA scientists have devised a new way to monitor how Arctic plants and soil are responding to increasing carbon dioxide levels in the atmosphere.
New results from a nine-year research project in the eastern Amazon rainforest finds that significant deforestation in eastern and southeastern Brazil turned what was once a forest that absorbed carbon dioxide into a source of planet-warming carbon dioxide emissions.
In May, NOAA's measurements at the Mauna Loa observatory averaged 419.13 parts per million. Scientists at Scripps calculated a monthly average of 418.92 ppm. It's the highest level since accurate measurements began 63 years ago.
Keeping track of ocean health is critical for understanding climate change, weather patterns, and the health of important fisheries. But how do NOAA and partner scientists gather data on such a vast environment?
Understanding the biologic contribution of CO2 to megacities' overall carbon emissions will be important for designing and evaluating mitigation strategies.
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.
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.
