Marine cloud brightening, a geoengineering approach to cooling the surface of the Earth by increasing the reflectivity of marine clouds, may be more difficult to execute than anticipated, according to a new NOAA study.
NOAA scientists are testing a reliable, low-tech, uncrewed glider that can return a small payload of scientific instruments from the stratosperhere to a pre-determined landing spot, potentially opening up vast new reaches of the atmosphere to scientific investigation.
NOAA scientists have devised a new way to monitor how Arctic plants and soil are responding to increasing carbon dioxide levels in the atmosphere.
New research from NOAA finds that fragrant personal care products - the stuff that makes you smell good - are now responsible for a significant amount of the ozone pollution known as smog that plagues major urban areas.
A large area of poorly oxygenated water is growing off the coast of Washington and Oregon. Scientists say oxygen levels may fall low enough to create "dead zones."
New results from a nine-year research project in the eastern Amazon rainforest finds that significant deforestation in eastern and southeastern Brazil turned what was once a forest that absorbed carbon dioxide into a source of planet-warming carbon dioxide emissions.
Findings of a new study of aerosols in the remote atmosphere finds that the northern stratosphere is significantlly more polluted than the south. Analysis of the aerosols suggests aviation is to blame.
The sudden and sustained risesine 2007 in atmospheric levels of the potent greenhouse gas methane has posed one of the most significant and pressing questions in climate research: Where is it coming from?
Two independent types of measurements show a strong warming trend during the 14-year period from 2005 to 2019.
In May, NOAA's measurements at the Mauna Loa observatory averaged 419.13 parts per million. Scientists at Scripps calculated a monthly average of 418.92 ppm. It's the highest level since accurate measurements began 63 years ago.
