Assessment

Why?

Strongest counted support: A University of Copenhagen release independently describes the six-category, 38-country wetland map at 10-metre resolution. weight 0.918000 evidence

Suppressed as dependent: The supplied passage directly reports six wetland types, 10-meter resolution, the mapped area estimate, and overall accuracy.

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.

  The excerpt explicitly states every quantitative and scope component of the claim.

• The primary Nature article reports mapping six natural and seminatural open wetland types across large parts of Europe at 10-m resolution, with 413,504 ± 17,782 km2 estimated area and 96.6 ± 0.3% overall accuracy.

Evidence against

None.

Qualifications

• The mapping is for the 2018 epoch and uses satellite observations spanning 2017–2019.

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.
