A recent NOAA-led study found the speed of movement of tropical cyclones, including hurricanes, has been slowing in recent decades, with more storms lumbering slowly over land and potentially causing more flooding. However, new research published in Nature by another NOAA scientist casts some doubt that tropical cyclones are slowing and that there’s a link to climate change.
For scientists at NOAA, Earth Day — and every other day of the year — is about getting to the bottom of some of the most pressing questions about the planet we call home: how it works, how it’s changing, and how humans are affecting it.
New NOAA research demonstrates that drones and weather balloons can gather data needed to improve weather forecasts in severe working environments.
Carbon dioxide levels measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory averaged more than 410 parts per million in April and May, the highest monthly averages ever recorded.
The warming influence from long-lived greenhouse gases rose again in 2017, reflecting ongoing changes to the atmosphere associated predominantly with human activities, NOAA scientists announced today.
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.
A new analysis of heat wave patterns appearing today in Nature Climate Change concludes that climate change driven by the buildup of human-caused greenhouse gases will overtake natural variability as the main cause of heat waves in the western United States by the late 2020s and by the mid-2030s in the Great Lakes region.
On Friday, August 25, U.S. Coast Guard Cutter Healy will sail from Dutch Harbor, Alaska, with a team of NOAA scientists and collaborators on a 22-day cruise to study environmental change in the western Arctic Ocean.
As scientists work to predict how climate change may affect hurricanes, droughts, floods, blizzards and other severe weather, there’s one area that’s been overlooked: mild weather. But no more.
NOAA’s Climate Program Office (CPO) has awarded $44.34 million for 73 new projects designed to help advance the understanding, modeling, and prediction of Earth’s climate system and to foster effective decision making.
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.
