In the western U.S., the impacts of drought conditions in the 21st century are increasingly evident as extended fire seasons, dwindling water supplies, and widespread tree mortality are becoming more common occurrences.
A new NOAA study published today in the journal Science Advances about four decades of tropical cyclones reveals the surprising result that reducing particulate air pollution in Europe and North America has contributed to an increase in the number of tropical cyclones in the North Atlantic basin and a decrease in the number of these storms in the Southern Hemisphere. The study also found that the growth of particulate pollution in Asia has contributed to fewer tropical cyclones in the western North Pacific basin.
NOAA atmospheric measurements are helping to support a national inventory of emissions from an important family of greenhouse gases.
What does Earth Day mean to scientists at NOAA's Geophysical Fluid Dynamics Laboratory (GFDL) - especially during our current era of climate change?
The newly released 2021 NOAA Science Report includes more than 60 stories that represent a selection of NOAA’s 2021 research and development accomplishments across the range of NOAA’s mission.
A new NOAA modeling study suggests climate change is likely to disrupt Pacific atmospheric rivers, which are important sources of snow and rain for west coast 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.
