Emissions of a banned ozone-depleting gas are back on the decline

Emissions of a banned ozone-depleting gas are back on the decline

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.

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.

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.
