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.
Scientists with NOAA's Global Monitoring Laboratory will evaluate the optimal placement of greenhouse-gas sampling inlets on a Boeing 737 flying testbed owned by Alaska Air during Boeing's 2021 ecoDemonstrator technology development program.
The annual analysis of samples collected by NOAA’s Global Greenhouse Gas Reference Network provides an updated measure of the excess heat trapped in the atmosphere by greenhouse gas pollution.
The dynamics that lift smoke from large wildfires into the upper atmosphere could potentially be employed one day to help temporarily cool the planet, based on the findings of a modeling study led by NOAA scientists.
