Some of the substitutes for ozone-damaging chemicals that being phased out worldwide under international agreements are themselves potent greenhouse gases and contribute to warming. This work was supported in part by NOAA’s Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) Program and NASA’s Atmospheric Composition Program.
