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?
Launching uncrewed systems to monitor climate and ecosystem changes in the U.S. Arctic, sequencing the genome for endangered marine species, and improving weather forecasts with advances in regional models — these are just a few of NOAA’s scientific achievements in 2020. The newly released 2020 NOAA Science Report highlights the ways these accomplishments — and many more — provide the foundation for vital services that Americans use every day.
A new National Academies of Sciences' report calls on several federal agencies to work together to improve techniques for measuring one of the most important greenhouse gases produced by humans - methane.
The Montreal Protocol, the international treaty adopted to restore Earth’s protective ozone layer, has had a major side benefit - reducing climate-altering greenhouse gas emissions from the U.S.
Methane emissions from fossil fuel development around the world are up to 60 percent greater than estimated by previous studies, according to new research led by scientists from NOAA and CIRES. The study found that fossil fuel activities contribute between 132 million and 165 million tons of the 623 million tons of methane emitted by all sources every year. That’s about 20 to 25 percent of total global methane emissions, and 20 to 60 percent more than previous studies estimated.
Carbon dioxide levels in the Earth’s atmosphere passed a troubling milestone for good this summer, locking in levels of the heat-trapping gas not seen for millions of years.
Human activity has increased the direct warming effect of carbon dioxide (CO2) in the atmosphere by 50 percent above pre-industrial levels during the past 25 years, according to NOAA's 10th Annual Greenhouse Gas Index .
The Bakken oil and gas field is leaking a lot of methane, but less than some satellites report, and less than the latest Environmental Protection Agency inventory for petroleum systems, according to the researchers’ calculations. That's the finding of the first field study measuring emissions of this potent greenhouse gas from the Bakken, which spans parts of North Dakota and Montana. The work was published today in the Journal of Geophysical Research: Atmospheres.
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.
