Emergence of a climate oscillation in the Arctic Ocean due to global warming

Nature Climate Change, Published online: 11 November 2024; doi:10.1038/s41558-024-02171-3

Abrupt transitions in the climate system are discussed mostly in terms of mean state changes. Here, the authors use simulations to show that a decline in Arctic sea ice can lead to a new multidecadal mode of surface temperatures in the Arctic Ocean.
