Domain-specific¶
- Carbon Source
- Terrestrial-ecosystem flux science — tagging forests, grasslands, and soils by net flux; the Amazon reads as a sink in a normal year and a source in a drought-or-fire year, and tilled soils or drained peat as sustained sources. Oceanography (carbon) — the ocean as a net sink via CO₂ dissolution or a regional source via outgassing, balanced against terrestrial fluxes to close the global budget. Soil science and wetland biogeochemistry — peat bogs as millennial sinks that flip to sources on drainage, and the multi-species subtlety of a wetland sourcing CH₄ while sinking CO₂. Permafrost and cryosphere studies — frozen soil as a long-run store that flips to an emitter past a warming threshold
This sourceReview concluding that carbon stored in frozen Arctic soils can be released as carbon dioxide and methane under warming, as a gradual and prolonged emission.

“Large quantities of organic carbon are stored in frozen soils (permafrost) within Arctic and sub-Arctic regions. A warming climate can induce environmental changes that accelerate the microbial breakdown of organic carbon and the release of the greenhouse gases carbon dioxide and methane.”

Verification¶
Does it exist? Not checked yet. This work's DOI is recorded above but has not been resolved against an external catalogue, so nothing here confirms the work exists.
Does it back the claim? Read against the text for 1 of 1 citation: 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.
