Assessment

Why?

Strongest counted support: The institutional release reports up to 5 billion tonnes CO2-equivalent of potential disturbance-associated soil-carbon loss relative to an undisturbed scenario. weight 0.918000 evidence

Suppressed as dependent: The supplied passage directly reports 0.8–4.9 Gt CO2-equivalent potential losses and their share of the mean storage pool, but not 2018 or annual-rate wording.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Leans supported to Leans contradicted.

  From New study pinpoints europe’s most critical wetlands for climate action Read 2026-09-29 Relevance STRONG Steps 1 Counted

  The release rounds the primary study’s upper estimate of 4.9 Gt CO2-equivalent.

• The supplied passage directly reports 0.8–4.9 Gt CO2-equivalent potential losses and their share of the mean storage pool, but not 2018 or annual-rate wording.

  From Highly fragmented European wetlands with uneven restoration needs Read 2026-09-29 Relevance MODERATE Steps 0 Counted

  The excerpt supports the magnitude and storage-pool interpretation but leaves the temporal qualifiers unstated.

• The primary Nature article characterizes 0.8–4.9 Gt CO2-equivalent as potential wetland carbon-stock losses under 2018 disturbance conditions and explicitly distinguishes this stock difference from an annual emissions trajectory.

  The passage directly states the range and clarifies its non-annual interpretation.

Evidence against

None.

Qualifications

• The full Nature passage supplies material qualifiers omitted from the counted anchor: the estimate is a 2018 stock difference against an undisturbed baseline, not an annual emission rate, and applies only to natural/seminatural open wetlands excluding historically lost, forested, and heavily drained wetlands.

  This directly narrows the time interpretation, baseline, denominator, and mapped-wetland scope of the 0.8–4.9 Gt estimate.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
