- Reservoir-Flux Network
- Biogeochemistry. The canonical case: the carbon cycle as reservoirs (atmosphere, ocean surface, deep ocean, biosphere, soils, fossil reserves) linked by photosynthesis, respiration, dissolution, and combustion fluxes, with total carbon conserved.
This sourceTreats the global carbon cycle as atmosphere–ocean–biosphere–soil–fossil reservoirs linked by conserved fluxes.

IPCC AR6 Ch. 5 presents the global carbon budget as stocks and fluxes balanced across atmosphere, surface and deep ocean, biomass, soils and fossil reserves.
“The rate of carbon accumulation in the atmosphere is equal to net land-use change emissions, including land management (called LULUCF in the main text) plus fossil fuel emissions, minus land and ocean net sinks (plus a small budget imbalance, Table 5.1).”
- Biogeochemistry. The canonical case: the carbon cycle as reservoirs (atmosphere, ocean surface, deep ocean, biosphere, soils, fossil reserves) linked by photosynthesis, respiration, dissolution, and combustion fluxes, with total carbon conserved.
- Rock Cycle
- The named transformations connect pairs of these — photosynthesis moves carbon from atmosphere to biomass, respiration and decay return it, burial moves it to sediment, combustion and volcanism return it to the atmosphere
This sourceDocuments carbon-cycle transformations (photosynthesis, respiration, combustion, burial) and how fossil-fuel emissions redistribute carbon across reservoirs, including ocean acidification.

IPCC AR6 Ch. 5 treats carbon exchange among atmosphere, land and ocean reservoirs and covers the named processes, but never lays out this simple reservoir-pair list of transformations.
“the net accumulation of GHGs in the atmosphere is controlled by biogeochemical source-sink dynamics of carbon that exchange between multiple reservoirs on land, oceans and atmosphere”
- The named transformations connect pairs of these — photosynthesis moves carbon from atmosphere to biomass, respiration and decay return it, burial moves it to sediment, combustion and volcanism return it to the atmosphere
Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 2 of 2 citations: 1 supported, 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
