The Annual Greenhouse Gas Index serves as a measure of global society's progress - or lack of progress - in reducing greenhouse gas emissions.
A new study published this week in the journal Science estimates the Southern Ocean absorbs 550 million tonnes of carbon from the atmosphere per year, confirming its role as a significant carbon sink.
NOAA scientists have devised a new way to monitor how Arctic plants and soil are responding to increasing carbon dioxide levels in the atmosphere.
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.
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.
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.
Results from a 2016 research cruise show ocean acidification has interfered with shell development of zooplankton that are a critical part of the marine food web.
Understanding the biologic contribution of CO2 to megacities' overall carbon emissions will be important for designing and evaluating mitigation strategies.
