Cordis´ (European Commission Community Research and Development Information Service) post on the recently article published by BC3 "Mitigation implications of an ice-free summer in the Arctic Ocean"Reaching global warming targets under ice-free Arctic summers requires zero emissions by 2045 Ice-albedo feedback as a result of sea-ice melting, notably in the Arctic, is known to reinforce global warming. What is less known, however, is the impact of a no-summer ice scenario on the world’s ambition to maintain global warming below 2°C by 2100. A study conducted under the TRANSRISK project paints a rather dark picture, highlighting the need to better understand the impact of rapid climate change in the region.
