Claim

The evidence concerns approximately the last 5,000–6,000 years and primarily summertime SST inferred from alkenone biomarkers, supplemented by planktonic-foraminifera and circulation proxies; the TraCE-21k comparison is a transient-model versus proxy comparison, not a direct instrumental SST validation.

Main unresolved issue: 1 counted evidence item has no independence review; repeats of one origin may be counted as several coverage:aa3bf774-f9a5-8aab-8162-53b23a1aef52

Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.

Why?

Strongest counted support: The primary article directly supports the late-Holocene time window, summertime alkenone interpretation, supplementary proxy context, and transient-model-versus-proxy comparison. weight 1.800000 evidence

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 Unresolved.

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 + 1.800000 (the counted weights) = 1.800000 → probability 0.8581

Under neighbouring settings of the same model: 0.7790 to 0.9121, a spread of 0.1331.

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.

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.
