* These last partially halogenated organic compounds, among which belong CFCs, HFCs and HCFCs. In this group the Freons were actually getting more dilute—a surprisingly pleasant outcome. (See the interview with the retired CEO of Conoco, Mr. Archie Dunham, on II:451.) But they were an exception to this story. Maybe that delayed the misery ahead. Meanwhile four other members (CFC-11, CFC-12, CFC-113 and HCFC-22) caused 85% of all halocarbon-induced warming. “The former three compounds have declining R[adiative] F[orcing] over the last 5 years but are more than compensated for by the increased RF from HCFC-22.”
