The Annual Greenhouse Gas Index serves as a measure of global society's progress - or lack of progress - in reducing greenhouse gas emissions.
NOAA atmospheric measurements are helping to support a national inventory of emissions from an important family of greenhouse gases.
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.
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.
An eight-year study of Boston’s natural gas system has revealed that emissions of methane, a powerful greenhouse gas, are significantly higher than previously estimated.
A new NOAA-led study of precipitation high in the Colorado Rockies aims to give water managers better forecasts for runoff in the critically important Colorado River Basin.
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.
The sudden and sustained risesine 2007 in atmospheric levels of the potent greenhouse gas methane has posed one of the most significant and pressing questions in climate research: Where is it coming from?
Scientists with NOAA's Global Monitoring Laboratory will evaluate the optimal placement of greenhouse-gas sampling inlets on a Boeing 737 flying testbed owned by Alaska Air during Boeing's 2021 ecoDemonstrator technology development program.
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.
