  • The long-term quantification of the Angulas Leakage is difficult due to its highly variable spatio-temporal nature and sparse observations. Here, the authors combine sea surface temperature with a series of ocean and climate model simulations to construct a 145-year long time series of Agulhas leakage.

  • Projections of Arctic warming have large uncertainties. Here the authors consider ocean heat transport and its contribution to Arctic warming; high-resolution model results show increased Bering Strait transport compared with lower-resolution results, with implications for projected warming rates.

  • Rare and extreme climate events have increasingly occurred in the Arctic since ~2000. This Review outlines the observed and projected changes in atmospheric, oceanic and cryospheric extremes and explains their increasing occurrence through a ‘pushing and triggering’ framework.

  • An underlying assumption of palaeoceanographic proxies is that they are representative of the water properties directly above their site of deposition. Here, the authors combine high-resolution particle tracking simulations and sedimentary proxy data to challenge this assumption.

  • The Beaufort Gyre in the western Arctic Ocean has accumulated a large amount of freshwater. Here, the authors show that a historical release in the 1980s resulted in a strong freshening of the western Labrador Sea, suggesting that a future release of the current freshwater volume could even be more impactful.

  • Deep waters of the Atlantic, Pacific and Indian Oceans upwell in the Southern Oceanbut the exact pathways are not fully characterized. Here the authors present a three dimensional view showing a spiralling southward path, with enhanced upwelling by eddy-transport at topographic hotspots.

  • Arctic cyclones have become more extreme and longer-lived since 1950 as a result of stronger lower-troposphere baroclinicity, amplified winter jet stream waves and strengthening of the lower-stratosphere Arctic vortex in summer, according to analyses of multiple reanalysis data sets.
