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.
Residents, communities and businesses now have easy access to climate projections, through a few easy keystrokes, for every county in the contiguous United States.
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 .
