Today the Summary for Policy Makers from our 2021 @AMAP_Arctic Assessment on impacts of short-lived climate forcers on the Arctic is released, to coincide with the @ArcticCouncil 2021 Arctic Ministerial in Reykjavik. Text here: amap.no/documents/doc/…

Some of key findings: 👇 CO2 emissions are the key driver of #Arctic warming, and steep immediate reductions in global CO2 emissions are required to mitigate long-term warming of the Arctic. Changes in SLCFs will impact Arctic temperatures in the near-term ~30 years.
