‘Atlantification’ of Arctic sea tipping it towards new climate regime – The research, published in Nature Climate Change, finds that warming conditions and decreasing sea ice volume “may soon” see the Barents Sea complete a transition from cold, fresh Arctic waters to a warm, salty Atlantic regime.

If current trends continue, the transition could occur “around 2040”, the lead author tells Carbon Brief. This would have “unknown consequences” for the wider ecosystem and commercial fishing, the study warns. https://www.carbonbrief.org/atlantification-arctic-sea-tipping-towards-new-climate-regime
