Assessment

Why?

Strongest counted support: UC Berkeley explicitly says the 1–3 gigaton global estimate is based solely on Mojave soils and could be higher. weight 2.000000 evidence

Suppressed as dependent: The global 1–3 gigaton estimate is based solely on Mojave soils, and the exact figure could be higher.

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.

  Directly supports the narrower limitation claim; the source presents it as a caveat to a global extrapolation.

• UC Berkeley explicitly says the 1–3 gigaton global estimate is based solely on Mojave soils and could be higher.

Inferences

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.
