A diagram to show 1990 conceptions of the sizes of the carbon reservoirs (Pg) and of the carbon fluxes (Pg/year) in the global cycle. The fluxes resulting from land use change (2.8 Pg/year), gross primary productivity of terrestrial plants (117.3 Pg/year), and ocean uptake (103 Pg/...
Implications to the carbon cycle Via groundwater-carbonate rock interactions, induced by CHTF, dissolved CO2 can be entrapped as carbonate alkalinity in groundwater (e.g., CaCO3 + CO2 + H2O = 2HCO3−+Ca2+) and reduce CO2 outgassing from the continental crust into the atmospher...
Chinese forests cover most of the representative forest types in the Northern Hemisphere and function as a large carbon (C) sink in the global C cycle. The availability of long-term C dynamics observations is key to evaluating and understanding C sequest
The elements of carbon sink monitoring are becoming more and more complete, and the spatial and temporal resolution is getting higher and higher. The key parameters of the ecosystem carbon cycle are detected from elements such as ecosystem classification and vegetation coverage characteristics, and new...
Multiple processes transport carbon into the deep ocean as part of the biological carbon pump, leading to long-term carbon sequestration. However, our ability to predict future changes in these processes is hampered by the absence of studies that have si
reverse weathering carbon cycle weathering climate silica Precambrian 1. Introduction The carbon cycle controls Earth's climate evolution on long timescales. Silicate weathering is a temperature dependent net sink for atmospheric CO2, and thus provides a natural thermostat to buffer Earth's climate agains...
The high binding energy between the B-sites and the Na+ ions caused a reduction in Na+ ions motion and trapped Na+ ions in the carbon structure that led to an extremely low potential plateau and a high irreversible capacity in the first cycle [223]. However, the first-cycle Coulombic ...
This method brings footprint calculations closer to life cycle assessments and thereby makes them more comprehensive. However, the task is complex and calculating footprints with endogenous capital is not yet as straightforward as calculating traditional CBA footprint. Including capital in footprint ...
