Deforestation, warming flip part of Amazon forest from carbon sink to source

Deforestation, warming flip part of Amazon forest from carbon sink to source

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.

Carbon dioxide peaks near 420 parts per million at Mauna Loa observatory

Carbon dioxide peaks near 420 parts per million at Mauna Loa observatory

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.

Tracking fossil fuel emissions with carbon-14

Tracking fossil fuel emissions with carbon-14

Researchers from NOAA and the University of Colorado Boulder have devised a breakthrough method for estimating national emissions of carbon dioxide from fossil fuels using ambient air samples and a well-known isotope of carbon that scientists have relied on for decades to date archaeological sites.

Warming influence of greenhouse gases continues to rise, NOAA finds

Warming influence of greenhouse gases continues to rise, NOAA finds

NOAA’s Annual Greenhouse Gas Index tracks the concentrations of greenhouse gases being added to the atmosphere principally from human-caused emissions. The AGGI then calculates the heat being added to Earth's atmosphere and oceans as a result.

NOAA exploring impact of COVID-19 response on the environment

NOAA exploring impact of COVID-19 response on the environment

NOAA has launched a wide-ranging research effort to investigate the impact of reduced vehicle traffic, air travel, shipping, manufacturing and other activities on Earth’s atmosphere and oceans due to the response to COVID-19.

Healing ozone layer stopped migration of Southern Hemisphere winds

Healing ozone layer stopped migration of Southern Hemisphere winds

A NOAA study published in the journal Nature demonstrates a profound effect of the Montreal Protocol: as levels of ozone-depleting chemicals controlled by the intenational treaty declined, a poleward shift of summertime circulation patterns in the Southern Hemisphere halted.

ABOUT US

Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
