The Annual Greenhouse Gas Index serves as a measure of global society's progress - or lack of progress - in reducing greenhouse gas emissions.
NOAA atmospheric measurements are helping to support a national inventory of emissions from an important family of greenhouse gases.
Craig N. McLean, assistant administrator of NOAA Research, who began his NOAA career as a uniformed officer in the NOAA Corps four decades ago and rose to lead the agency’s research division and become a champion of ocean exploration, scientific integrity and science diplomacy, has announced his plan to retire from public service on April 1, 2022.
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.
Two independent types of measurements show a strong warming trend during the 14-year period from 2005 to 2019.
New analyses of global air measurements show that five years after an unexpected spike in emissions of the banned ozone-depleting chemical chlorofluorocarbon CFC-11, they dropped sharply between 2018 and 2019.
Barely had the ink dried on the partnership agreement signed by NOAA and ocean explorer Victor Vescovo, owner of Caladan Oceanic LLC, when his team headed out to the Pacific Ocean to dive and map the Mariana Trench, and answer the questions -- how deep and where exactly is the bottom of the ocean.
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 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.
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.
