A comparison of Greenland ice sheet models shows that while the surface mass balance is most realistic in the most complex models, simpler and faster models compare fairly well.

Ocean currents have brought more heat into the northern seas after 2001. The northern extension of the Gulf Stream has warmed and probably also strengthened.

Cyclones in the Atlantic and Pacific Oceans are affected by the Gulf Stream and the Kuroshio. The temperature of the water below is only one of the factors controlling their development.

In 10,000 years the Greeland ice sheet will be gone, but what about Antarctica? Heiko Goelzer presents research for the coming millennia.

Widespread sea ice decline within 250 years unleashed abrupt climate change during the last glacial period. A new study documents that the cause of the severity of the changes resides in the ocean. 

The jet stream is a highway for cyclones, while the sea ice edge has been thought to be a fuel station. Erica Madonnas new study shows that the fuel for cyclones is not simply linked to the ice edge.

The ocean is a questionable babysitter. Kristine Flacké Haualand takes us to the cradle of midlatitude cyclones.

You have very likely heard about the Gulf Stream. The Iceland-Faroe Slope Jet, you have never heard of. This current is the newest one on the map.

Supercoolness is less exceptional than you may think. Seals diving under Antarctic sea ice came back with data proving they live in the supercoolest part of the world.

Though sea-level contributions may be the same, increasing the spatial resolution in models provides more details about outlet glaciers. Heiko Goelzer writes about a new study of the Greenland ice sheet.
