This review paper provides a clear message: the frequency and length of future sea ice-free periods in the Arctic directly depends on future CO2 emissions. Only the lowest emissions scenario, consistent with 1.5\u00b0C offers a possibility of maintaining a perennial sea ice cover. Up to three months of sea ice-free conditions would result with global temperatures at 2\u00b0C, extending to four months with \u22652.5\u00b0C warming, five months with \u22653.5\u2009\u00b0C, and eight months with very high emissions (SSP5-8.5). Briefly exceeding the lower Paris Agreement 1.5\u00b0C temperature threshold would still lead to summer sea ice-free periods that occur once every several decades, but these periods could fully disappear with minimal overshoot and sufficient negative emissions that lower CO2 in the atmosphere. An ice-free Arctic Ocean is likely to have multiple deleterious impacts and feedbacks, not only regionally but globally. The study concludes that ice-free conditions can “remain an exception rather than the new normal” if temperatures stay at or return below 1.5\u00b0C with only temporary overshoot.<\/p>\n
