Earth’s oceans, forests and other ecosystems continue to soak up about half the carbon dioxide emitted into the atmosphere by human activities, even as those emissions have increased, according to a study by University of Colorado and NOAA scientists published today in the journal Nature.
The concentration of carbon dioxide in the atmosphere of Barrow, Alaska, has reached a new milestone this spring, according to NOAA measurements.
Arctic warming has thinned springtime sea ice across the Arctic Ocean. A new study shows that this alters the chemistry of the atmosphere near the Earth’s surface and may increase the amount of toxic mercury contaminating the region.
NOAA researchers will be using several innovative tools, techniques, and research results during the 2012 hurricane season to continue to improve hurricane forecasting. Read our 2012 hurricane research news briefs to learn more.
Today marks the beginning of a large-scale, comprehensive field project to measure how thunderstorms transport, produce and process chemicals that form ozone, a greenhouse gas that affects Earth's climate, air quality and weather patterns.
Starting today, NOAA is using a sophisticated new weather forecast computer model to improve predictions of quickly developing severe weather events including thunderstorms, winter storms and aviation hazards such as clear air turbulence.
A smoke-related chemical, isocyanic acid, may be a significant air pollutant in some parts of the world, especially where forest fires and other forms of biomass burning are common.
The potent greenhouse gas methane is seeping out of parts of the Arctic Ocean, and the discovery may represent another cycle contributing to climate warming in the region.
Springtime air pollution from Asia, swept across the Pacific Ocean on winds, can contribute to episodes of high surface ozone pollution in the western United States.
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.
