Definition Organic carbon (OC ). In geochemistry, carbon that occurs in materials of ultimately biological origin and that can be oxidized. Organic matter (OM) is the material that contains organic carbon (OC). Degradation. Transformations of OM within the range of temperatures, pressures and envi...
Loss of irrecoverable carbon cuts into this budget. Irrecoverable carbon represents 20% of the total manageable ecosystem carbon. Globally, 79.0 Gt (57%) of irrecoverable carbon is found in biomass while 60.0 Gt (43%) is in soils. Additional carbon could be both vulnerable and ...
Integrating this number into the global carbon budget is therefore necessary to refine biogeochemical models and to improve predictions of the future ocean state. Maximum potential Phaeodaria-driven attenuation is found in the Southern Ocean, where it ranges between 11.2 and 23.4% of the ...
For a given carbon budget, this suggests a clear trade-off between LULUCF and BECCS when the strength of land mitigation policy is varied, driven by resource competition. The 2 °C A/R-Focused scenarios, which specifically support forest carbon storage, result in higher total land-based CDR...

This means passing the 500 Gt carbon budget that the IPCC linked to the 1.5°C goal. I have discussed this in many earlier posts, for example here and here. However, passing 1.5°C in the short term certainly isn’t the end of the story. Many recent IPCC scenarios also show 1.5°C...
NEO provided another perspective on achieving NZE by 2050, placing it in the context of the carbon budget that is available before reaching a 2°C increase in average global temperatures compared to pre-industrial times, rather than 1.5°C under the IEA Roadmap and the WETO. Based on ...
The main goal of the paper is to define the level of energy efficiency in the economies of selected countries in the Balkan region that have opted for the EU Green Deal, a circular economy, and a transition to carbon neutrality. Energy efficiency, as a d
Soft carbon-rich material that is <65% organic matter is captured using the rapid protocol, which lies beneath peat using our definition, but above the more typical mineral soil. b, Relationship between core depth (in m) and total carbon stocks (in Mg C ha−1) for cores from the ...
The Arctic has experienced the most rapid change in climate of anywhere on Earth, and these changes are certain to drive changes in the carbon budget of the Arctic as vegetation changes, soils warm, fires become more frequent, and wetlands evolve as permafrost thaws. In this study, we review...
