New research describes one of the processes driving the North Pacific’s trajectory into uncharted waters. 

Two experimental tools that will speed fire detection and warning got a week-long test run last month during a series of hands-on simulations in NOAA’s new Fire Weather Testbed.

NOAA scientists and several partners are taking a fresh look at persistent air pollution problems bedeviling the nation’s two largest Intermountain metro regions, Denver and Salt Lake City, from the ground, in the air, and from space, during new research projects launched this month. 

As climate change continues to supercharge storms that threaten existing infrastructure, there’s an urgent need to modernize estimates of probable maximum precipitation and improve the science behind them.

New research by a team including current and former NOAA-affiliated scientists has shown that atmospheric concentrations of a class of ozone-depleting chemicals used as refrigerants, […]

Concentrations of N2O, a potent greenhouse gas, are higher than all major model projections

Carbon dioxide is accumulating in the atmosphere faster than ever — accelerating on a steep rise to levels far above any experienced during human existence, scientists from NOAA and the Scripps Institution of Oceanographyoffsite link at the University of California San Diego announced today.

May 17 2024 marks 50 years of NOAA’s continuous measurements of atmospheric carbon dioxide concentrations at the Global Monitoring Laboratory’s Mauna Loa Observatory.

A new study finds that air pollutants emitted from cooking can account for nearly a quarter of human-caused volatile organic compounds in dense urban areas.

Levels of the three most important human-caused greenhouse gases – carbon dioxide (CO2), methane and nitrous oxide – continued their steady climb during 2023, according to NOAA scientists.
