It was one of the major scientific discoveries of 2018: Emissions of an ozone-destroying chemical responsible for creating the Antarctic ozone hole were unexpectedly rising again, in an apparent violation of an international ban on its manufacture and use. The finding was reported by NOAA scientist and CIRES Fellow Stephen Montzka and an international team of colleagues.
Where were the emissions coming from? A new study published today in Nature provides an answer.
Record levels of greenhouse gas pollution continued to increase humanity’s impact on the atmosphere’s heat-trapping capacity during 2018, according to a yearly analysis released by NOAA scientists today.
Natural gas production in the United States has increased 46 percent since 2006, but there has been no significant increase of total U.S. methane emissions and only a modest increase from oil and gas activity, according to a new CIRES-led study.
CIRES is a partnership of NOAA and the University of Colorado Boulder.
