Claim

Under the study’s 2025–2100 SSP5-8.5 scenario combining projected precipitation and socioeconomic conditions, 32.1% of global land was classified as high priority for new gauges, versus 17.7% under SSP1-2.6.

Assessment

Supported

Score: 0.8581 under ledger-default@0.3.0 at snapshot 27745

Main unresolved issue: 4 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:b359a17c-97bc-824c-91ad-6fa8f1aae9df

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

Why?

Strongest counted support: The National Natural Science Foundation of China reports that priority deployment regions could expand to 32.1% of global land under a high-emissions scenario. weight 1.800000 evidence

Suppressed as dependent: The supplied passage directly reports 32.1% under SSP5-8.5 and 17.7% under SSP1-2.6 for 2025–2100 global land priority.

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.

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.
