Substantial twentieth-century Arctic warming caused by ozone-depleting substances

Arctic warming is attributed to GHGs and feedbacks, but the specific contribution of ozone-depleting substances (ODS)—also potent GHGs—has never been quantified. Here, model simulations show that ODS may have contributed half of the Arctic warming during the period 1955–2005.
