Carbon sequestration, as a biological process, refers to the capture and long-term storage of inorganic carbon, primarily in the form of atmospheric CO₂, into organic and inorganic carbon pools mediated by living organisms. In terrestrial ecosystems, plants, fungi, and microbes fix CO₂ via photosynthesis and chemoautotrophy, transferring carbon into biomass, soils, and stable humic substances. In aquatic systems, phytoplankton, macroalgae, and microbial communities incorporate CO₂ into organic matter, some of which is exported to deeper waters and sediments through the biological pump. Biological carbon sequestration regulates carbon cycling, ecosystem productivity, and contributes to the buffering of atmospheric CO₂ concentrations.
Mud is messy. For some, it's a plaything. To many, it can mean real hardship. Mud, though, is often overlooked, particularly when it lies out of sight. Deep down at the bottom of the sea, it is one of the most important natural ...

A team of meteorologists, Earth scientists and oceanographers at Sorbonne Université, working with one colleague from Université Paris-Saclay and another from Université Brest, all in France, has developed a simulation that ...
Organic particles that settle on the seabed ensure CO2 stays locked. However, natural gel-like substances slow down this process. Such microscale mechanisms play a crucial role in enhancing climate predictions.

To reach the goals of the Paris Agreement, we not only have to reduce CO2 emissions, but also remove CO₂ from the atmosphere (carbon dioxide removal, CDR) on a large scale. This can involve both land- and ocean-based methods.
