New analyses of global air measurements show that five years after an unexpected spike in emissions of the banned ozone-depleting chemical chlorofluorocarbon CFC-11, they dropped sharply between 2018 and 2019.
New research indicates that man-made clouds formed along shipping routes dissipate too quickly to provide insight into the cooling effect of naturally occuring marine clouds.
Known for precipitating outbreaks of Arctic air, stratospheric events in polar regions often cause other kinds of extreme weather. Since the stratosphere takes a long time to recover after these events, scientists may be able to improve predictability of extreme weather weeks ahead of time.
NOAA scientists project the maximum Great Lakes ice cover for 2021 will be 30 percent, higher than last year’s maximum of 19.5 percent, but part of a long-term pattern of declining ice cover likely driven by climate change.
Results from a 2016 research cruise show ocean acidification has interfered with shell development of zooplankton that are a critical part of the marine food web.
NIDIS, NOAA’s National Integrated Drought Information System, has launched a redesigned U.S. Drought Portal to better serve stakeholders, decisionmakers, the media, and the public.
Congress voted on January 1, 2021 to reauthorize and strengthen the National Oceanographic Partnership Program, a 23-year old program created by Congress to facilitate ocean-related partnerships between federal agencies, academia and industry to advance ocean science research and education.The reauthorization passed Congress as an amendment included in Section 1055 of the National Defense Authorization Act for Fiscal Year 2021.
The National Sea Grant College Act was reauthorized and amended by Congress and signed by President Donald J. Trump on December 18, 2020. The reauthorization, titled the “National Sea Grant College Program Amendments Act of 2020,” includes several updates to Sea Grant’s authorizing legislation. The Act serves as a guiding framework upon which Sea Grant operates and serves America’s coastal and Great Lakes communities.
From predicting smoke movement from massive wildfires, to investigating how marine life is responding to a quieter ocean, 2020 was a big year for NOAA science. As this unprecedented year draws to a close, we’re looking back at some of our biggest research endeavors in 2020. Here are 5 of our most-read stories from the last year.
November has jumped 2020 back on the “top three warmest” track becoming the second warmest November in the 141 year record, according to the latest monthly summary from the National Centers for Environmental Information.
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.
