Assessment

Why?

Strongest counted support: UC Berkeley reports temperature-driven CO2 adsorption and release in Mojave soils and estimates a 1–3 gigaton annual global desert-soil exchange. weight 2.000000 evidence

Suppressed as dependent: The passage directly states that Mojave soils took up more carbon dioxide as they cooled and released it as they warmed, driven by adsorption.

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.

Qualifications

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

  This directly limits the global extrapolation underlying the target estimate.

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.
