A new global ice sheet reconstruction for the past 80 000 years in Nature Communications.

Future climate scenarios are beyond comparison with recent times. When evaluating models, researcher Petra Langebroek goes 50 million years back.

As the ice was retreating at the end of the ice age, the melting was suddenly interrupted. A cold period of more than a thousand years followed.

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.
