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.

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

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

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.

"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.

Planting trees to mitigate climate change is useful in the tropics. At higher latitudes trees can have a warming effect.
