Boaty McBoatface makes significant climate change discovery on first mission

[AirPoh]

Its findings, published in the journal PNAS on Monday, revealed how increasingly strong winds in the region are causing turbulence deep within the sea, and as a result mixing warm water from middle levels with colder water in the abyss.


That process is causing the sea temperature to rise, which in turn is a significant contributor to rising sea levels, scientists behind the project said.

Good for Boaty!

So the other side of the ocean being warmed more quickly is that the atmosphere is being cooled by this effect.

Effect of wind speed and leads on clear-sky cooling over Arctic sea ice during polar night https://journals.ametsoc.org/doi/abs/10.1175/JAS-D-18-0277.1

... The cooling time scale shows a nonmonotonic dependency on wind speed being lowest for the threshold value of wind speed and increasing for weak and strong winds. Theoretical solutions agree well with results of a more realistic single-column model and with observations performed at the three Russian “North Pole” drifting stations (NP-35, 37 and 39) and at the Surface Heat Budget of the Arctic Ocean ice camp. Both modelling results and observations show a strong implicit dependency of the net longwave radiative flux at the surface on wind speed.
