A new Science paper shows that human-caused changes to Amazonian ecosystems are hundreds to thousands of times faster than those of natural climatic and geological processes.

The circulation in the North Atlantic Ocean can dampen or enhance temperature increase and ice melt in certain decades. Researcher warns against interpreting reduced temperature increase as a sign of a slow-down in climate change.

Variations on various time scales can lead to apparent intensifications or pauses in global warming. Nour-Eddine Omrani writes about his recent study on the mechanisms behind oscillations in the North Atlantic.

Gliders repeat the surveys of the 1970s, what is new since then?

The North Icelandic Irminger Current may be seen as the Gulf Stream’s little finger. Follow this finger to its tip in Stefanie Semper's account of her new study.

While in most earlier climate models, the water flowing into the Nordic Seas was too cold, current models represent both the water temperature and the resulting heat transport better.

The deep-ocean floor is the least explored ecosystem on the planet. DNA collected during 15 international deep-sea expeditions reveal the regions and organisms most important for removing carbon from the surface. Tristan Cordier writes about his new study.

Interdisciplinary results of MOSAiC drift published

Researchers unveil a new relationship for climate models linking carbon and heat uptake with the water-column stability in the Southern Ocean.

Global warming changes the conditions for ecosystems in the Barents Sea. A recent study found large variations between years and decades, though only modest changes on longer time scales.

Pollen can travel far through the air, allowing scientists who find them to trace the winds of the past. In South Georgia ancient pollen may reveal shifts in the westerlies.

With equipment normally found in hospitals, geologists can analyze material quicker. Jan Magne Cederstrøm writes about the use of CT scans in a study of debris transported by glaciers.

With a new La Niña in the Pacific, colder conditions could be expected in the North Atlantic. However, in northern Europe and Russia, climate warming balances the cooling.

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.

Oxygen depletion is affecting the ecology in the open ocean as well as near the coast. Anne Gro Vea Salvenes and Elin Darelius write about a recent study aiming to learn more about deoxygenation and its impact. 

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.
