In the last decades, little sea ice in the Arctic in fall has been associated with cold winters in Europe. A new study signals little reason to prepare for frosty nights and heavy snow, despite less than normal ice in the north.

Have you ever wanted to go back in time? It is not so easy in the real world, but in the model world anything is possible.

Earth has been a snowball. In a new study, Heiko Goelzer and colleagues have used an Earth system model to study the transitions between a glaciated and a non-glaciated Earth, around 700 million years ago.

"The human footprint is everywhere, even on remote islands", John Birks writes about a new study of past ecology. All around the world, human arrival on islands rapidly affected the local biodiversity.

During the Last Glacial Maxium the atmosphere contained less than half as much CO2 as today. New study finds that both the biological carbon cycling and the ocean circulation were different. 

Mighty floods have carved out deep canyons on Earth. New research suggests this required less power than previously believed. Collecting such data, however, may be demanding. 

The Norwegian Government's Longship project and the work of storing CO2 under the seabed in the North Sea depend on it: That we have methods to detect leaks and secure the stocks. Now we are one step closer to the goal.

The ocean plays a crucial role in climate regulation, absorbing about 25 percent of the CO2 humans emit to the atmosphere. A new UNESCO report highlights key issues and important questions within ocean carbon research.

Injecting particles into the atmosphere would reduce the temperature increase. But for the world’s ecosystems there is no alternative to mitigation efforts.

Sea level variations in Northern Europe are influenced by winds high above the Atlantic, new study shows. In the western part of the North Sea, the wind direction is more important than the wind speed.
