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

Five years after an unexpected spike in emissions of the banned ozone-depleting chemical chlorofluorocarbon CFC-11, emissions dropped sharply between 2018 and 2019, new analyses of global air measurements show.

NOAA’s greenhouse gas index up 41 percent since 1990

NOAA’s Annual Greenhouse Gas Index, which tracks the warming influence of long-lived greenhouse gases, has increased by 41 percent from 1990 to 2017, up 1 percent from 2016 -- with most of that attributable to rising carbon dioxide levels.

Emissions of ozone-destroying chemical controlled by Montreal Protocol rising again, NOAA data shows

Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production in 2010, a new NOAA study shows.

Ozone treaty taking a bite out of US greenhouse gas emissions

The Montreal Protocol, the international treaty adopted to restore Earth’s protective ozone layer, has significantly reduced emissions of ozone-depleting chemicals from the United States. In a twist, a new study by NOAA and CIRES scientists shows the 30-year old treaty has had a major side benefit - reducing climate-altering greenhouse gas emissions from the U.S.

Possible new threat to Earth’s ozone layer

The Montreal Protocol has been hailed for controlling chlorine-based chemicals that created a vast hole in the ozone layer over Antarctica. But new research by British and American scientists suggest a chemical not controlled by the international treaty poses a potential risk to the Earth’s protective ozone layer.

Study published on reduced lifetime for a future strong greenhouse gas

NOAA/ESRL scientists and their colleagues at the University of East Anglia, Utrecht University, and NCAR calculated an atmospheric lifetime of the trace gas, sulfur hexafluoride (SF6), based on measurements in the polar stratospheric vortex and modeled transport into the stratosphere.

ESRL's Brad Hall wins Governor's Award for High Impact Research

Brad Hall, a research scientist in the Global Monitoring Division of NOAA/ESRL, has been named a winner of the 2016 Governor's Award for High-Impact Research for his work on improving existing techniques to make calibration standards and measurements of very low concentrations of greenhouse gases such as carbon dioxide, methane, nitrous oxide and ozone-depleting gases like chlorofluorocarbons.
