When warmer summers eat at the permafrost, pecking beaks hardly make the situation better. 

The ocean takes up more than three times as much CO₂ from the atmosphere as in 1860. The main culprit is the higher concentration of CO₂ in the atmosphere. Emissions have not stopped rising, new report states.

The oceans have relieved the atmosphere from ¼ of anthropogenic CO2 emissions. In the Arctic, thawing permafrost may weaken this mechanism, new research indicates.

To know whether emission treaties are complied with, all CO2 must be traceable. Incomplete bookkeeping sent scientists on a search in the Greenland Sea.

In February Nadine Goris started as co-leader on carbon system. 

While the Arctic tundra loses color as the permafrost thaws, cities are greening.

Global CO2 emissions have increased from last year. This brings both emissions and the CO2 content in the atmosphere to a record high.

The world’s oceans take up twenty five percent of our annual CO2 emissions to the atmosphere. This helps slow down global warming. Keeping track of this uptake is essential for understanding climate change.

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.

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.

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. 

"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. 

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.

Afforestation in Norway can increase local temperatures in spring by as much as 1 ^oC. 

Forests do not only affect the climate, but also the people nearby, climate researcher Hanna Lee writes.

The idea of planting trees can easily be misinterpreted. There is a difference between afforestation, reforestation and forest restoration.

There’s something a lot of people don’t know about soil.
