Efficiency of short-lived halogens at influencing climate through depletion of stratospheric ozone 3 March 2015

Efficiency of short-lived halogens at influencing climate through depletion of stratospheric ozone

As another example of NOAA’s ongoing atmospheric measurements providing an early warning system to ensure sustainable development on global scales, a new study co-authored by Stephen Montzka of ESRL and supported by the CPO/AC4 program has found that atmospheric concentrations of chlorinated hydrocarbon (dichloromethane) gas have increased by a factor of 2 since the late 1990s throughout the globe.
