Main findings:

The observed 2012 record low in Arctic sea ice extent is extremely unlikely to have occurred due to internal climate variability alone, according to the models, i.e., and has a much greater likelihood of occurrence in the “forced plus internal variability” scenario. The 2012 anomaly is significantly stronger than the multimodel’s mean response to both anthropogenic and natural forcing combined.
