Claim

In the palsa permafrost soil under anoxic conditions, inoculation with its own active-layer community, compared with the control, quintupled cumulative methane production over six months and increased cumulative estimated warming potential by 35%, using GWP100 for non-fossil methane.

Why?

Strongest counted support: The controlled Palsa-PF anoxic incubation directly reports fivefold six-month methane increase and 35% higher GWP100 CO2-equivalent after active-layer inoculation. weight 2.000000 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.

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.
