While the shade offered by clouds on a hot sunny day can be obvious, quantifying the actual climate impact in terms of solar energy remains a challenging task. This is because the volume, thickness, and lifetime of marine clouds can change rapidly, and the processes that govern how and where clouds form and how gases and aerosols in the air interact with cloud droplets are highly complex. In a marine environment, many of those gases and aerosols in the air come from the ocean itself.
An annual analysis of air samples collected at remote sites around the globe that is tracking a continued decline in the atmospheric concentration of ozone-depleting
Large wildfires and severe heat events are happening more often at the same time, worsening air pollution across the western United States, according to a
Spectacular footage from inside a hurricane; a major ocean mapping milestone; new insights on the continued impacts of climate change, and much more — 2021
For nearly 50 years, NOAA’s Barrow Atmospheric Baseline Observatory has provided a window on the world, producing a record of changes that have a profound
From warmer ocean temperatures to longer and more intense droughts and heat waves, climate change is affecting our entire planet. Scientists at NOAA have long worked to track, understand and predict how climate change is progressing and impacting ecosystems, communities and economies.

In late February, as the Southern Plains and Gulf Coast suffered through an unusually strong blast of wintry weather, weather talk turned to the polar vortex and the possibility that the extreme cold was yet another example of weather-gone-wild due to global warming.
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.
A NOAA study published in Nature Geosciences takes a new look at faint, old smoke and finds that it is just as important an influence on the climate as the thick plumes produced by active fires.
