Halogenated compounds responsible for one third of global warming in the late 20th century
Halogenated compounds played a major role in global warming and Arctic sea ice loss in the late-20th century, a new study has found. Organic halogen compounds are known to have depleted atmospheric ozone concentrations, famously contributing to the ozone hole over the Antarctic. But until now, few studies have examined their other effects on climate, beyond their impact on stratospheric ozone.
