New Paper: Banned Halocarbons Still Responsible for HALF of Arctic Warming and Sea-Ice Loss: 1 of 2

A new paper concludes that between 1955 and 2005 about half of the surface warming in the Arctic, and about half of the Arctic sea-ice extent loss was actually due to Ozone Depleting Substances (ODS’s). ODS substances are trace gases, most notably CFC-11 and CFC-12 that were banned globally by the Montreal Protocol agreement in 1987. The ban was due to the destruction of the protective ozone layer, enacted shortly after the Antarctic ozone hole was first discovered. The paper also determined that the Arctic effects are due to the GHG properties of the ODS materials, and NOT the ozone destroying effects.
