> somehow the only way people got a hold of this was by looking at the ozone layer. This is not correct, and we can't attribute changes to ozone that precisely with the wide natural, seasonal variations. "A U.S. observatory in Hawaii found CFC-11 mixed in with other gases that were characteristic of a source coming from somewhere in eastern Asia" This was probably from the Earth Systems Research Laboratory, best known for its CO2 monitoring: https://www.esrl.noaa.gov/gmd/obop/mlo/ |
