Claim

In the Nature Plants study's Northern Hemisphere datasets and experiments, post-frost vegetation recovery exceeded the loss and annual productivity exceeded the non-frost baseline in 21.5–41.0% of late-spring frost events.

Assessment

Supported

Score: 0.9734 under ledger-default@0.3.0 at snapshot 27745

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

2 independent evidence lineages · review checks 1 of 4 · stability HIGH

Main unresolved issue: 4 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:1d24667d-6502-8321-a8f6-072074f6429f

Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.Every quoted passage was confirmed on the page when Galedra fetched it.

Why?

Strongest counted support: A secondary report corroborates that Northern Hemisphere vegetation frequently exceeded non-frost productivity after late-spring frost rather than merely recovering to baseline. weight 1.800000 evidence

Suppressed as dependent: The abstract directly gives the 21.5–41.0% event range and defines overcompensation as recovery exceeding loss with productivity above baseline.

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 + 3.600000 (the counted weights) = 3.600000 → probability 0.9734

Under neighbouring settings of the same model: 0.9255 to 0.9908, a spread of 0.0653.

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.

None.

Qualifications

The 21.5–41.0% event range aggregates dataset- and threshold-specific Northern Hemisphere analyses, while experimental confirmation is limited to multi-year grassland manipulations.

Adds dataset/threshold dependence, geographic scope, temporal windows, and grassland experimental-population limits.

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.
