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.
