1 depends 0.86 The answer says “Large-scale, unilateral deployment is not acceptable now” but also states “The acceptability of SRM depends on scientific evidence, distribution of risks and benefits, and — critically — robust, democratically legitimate international governance and safeguards,” indicating conditional acceptability.
2 depends 0.92 The answer says 'No—not as a first‑line solution' but qualifies that it 'might be considered as an emergency last‑resort measure under very strict international governance,' indicating conditional acceptability.
3 depends 0.95 The answer says SGE is "Not right now" and "not acceptable as a substitute for mitigation," but adds it "may... be considered as a tightly governed, emergency backstop" only under very strong scientific, ethical, legal and governance conditions.

1 depends 0.92 The answer explicitly frames this as hinges on tradeoffs and presents multiple dimensions: 'it might become necessary as a harm-reduction tool if we fail at emissions cuts' but using it as primary strategy 'seems like treating symptoms while ignoring the disease.' The response systematically outlines conditions, concerns, and contexts that would affect acceptability rather than issuing a binary ju
2 depends 0.92 The answer explicitly states 'The honest answer is we don't know if it's acceptable because it depends on: How aggressively we pursue emissions cuts (not either/or), Whether governance structures can actually be built, How impacts distribute globally.' The assistant maps genuine tradeoffs and concludes acceptability is contingent on multiple unresolved factors rather than offering a definitive per
3 depends 0.92 The answer explicitly maps tensions and concludes with 'the honest middle ground' that research is warranted but deployment depends on context: 'Probably not as primary solution while emissions-reduction is still feasible' but 'Possibly relevant as complement if warming proves worse than expected.' This conditional stance indicates permissibility depends on circumstances, not a blanket yes or no.

Gemini modal depends [depends, no position, no position] · stability 1.00

1 depends 0.90 The answer presents arguments for both sides and concludes that whether it will ever become acceptable depends on how severe the climate crisis becomes and whether international governance can be established.
2 no position 0.95 The answer declines to take a stance, stating that 'There is no global consensus on whether deployment is acceptable' and neutrally presenting arguments on both sides.
3 no position 0.95 The answer declines to take a definitive stance on whether it is acceptable, instead framing it as 'a subject of intense debate' and presenting balanced arguments for and against.
