Claim

Assessment

Supported

Score: 0.9843 under ledger-default@0.3.0 at snapshot 27745

3 of 4 review checks done · 1 counted · 2 by the author only

Main unresolved issue: 8 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:06fbae8c-c922-889b-ade3-49fdafc73382

Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.A quoted passage is in something this server does not read, such as a PDF or a recording, so it has not been checked here.

Why?

Strongest counted support: The primary Nature Geoscience article directly reports that rain-induced dilution accounts for about two-thirds of additional ocean uptake through freshening-induced carbonate-system repartitioning. weight 1.800000 evidence

Suppressed as dependent: The study attributes about two-thirds of total additional rain-related ocean CO2 uptake to dilution-driven carbonate-system repartitioning.; The passage directly attributes about two-thirds of additional rain-driven ocean CO2 uptake to freshening-induced carbonate-system repartitioning.

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 Supported to Supported.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

prior 0.50 → log-odds 0.000000 + 4.140000 (the counted weights) = 4.140000 → probability 0.9843

Under neighbouring settings of the same model: 0.9477 to 0.9954, a spread of 0.0477.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

Evidence for

The study attributes about two-thirds of total additional rain-related ocean CO2 uptake to dilution-driven carbonate-system repartitioning.

From Global carbon dioxide flux into the surface ocean intensified by rain-induced dilution Read 2026-09-29 Relevance DIRECT Steps 0 Counted
The supplementary analysis reinforces that rain dilution is a major modeled component of the rain-related global air–sea CO2 exchange estimate, while emphasizing uncertainty in current ocean carbon-sink quantification.

From Supplementary Information: Global carbon dioxide flux into the surface ocean intensified by rain-induced dilution Read 2026-09-29 Relevance MODERATE Steps 0 Counted

Supplementary information from the same study; it corroborates the modeled mechanism but is not an independent research lineage and does not restate the exact two-thirds figure.
The primary analysis attributed about two-thirds of rain-related additional ocean CO2 uptake to dilution-driven carbonate-system repartitioning.

Qualifications

The primary paper’s global flux map and summary use year-2000 inputs.

From Global carbon dioxide flux into the surface ocean intensified by rain-induced dilution Read 2026-09-29 Relevance DIRECT Steps 0 Counted

Material time-range qualifier: the reported global estimate is for year 2000 inputs.
The primary paper’s precipitation inputs and analysis span 60°S–60°N.

From Global carbon dioxide flux into the surface ocean intensified by rain-induced dilution Read 2026-09-29 Relevance DIRECT Steps 0 Counted

Material spatial-scope qualifier: the analysis excludes latitudes outside 60°S–60°N.
The primary paper explicitly says rain-dilution representation and its uncertainty remain poorly constrained.

Material model-uncertainty qualifier: dilution is model-dependent and not statistically robustly quantified.

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.
