1 depends 0.87 The answer says “No — not at present” and that large-scale SRM is “not ... acceptable” now, but adds it “may be considered only as a strictly last-resort emergency option under tightly constrained, transparent, and democratically legitimate rules.”
2 depends 0.90 Says deployment is 'Not today' and 'not broadly acceptable as a routine climate policy' but could be considered 'if at all — under very strict, internationally agreed conditions' and only as an emergency option.
3 depends 0.90 The answer states “Not yet — large-scale deployment ... is not currently acceptable as a routine response,” but also allows that in a future extreme emergency “tightly constrained deployment might be considered,” so acceptability depends on strict conditions.
4 depends 0.95 The answer states 'Short answer: No — not yet' but adds it 'might, under very strict conditions and only as a last-resort emergency measure, become acceptable in the future' after stringent scientific, ethical, legal and institutional criteria are met.
5 depends 0.92 Says 'Not at present' and that large‑scale deployment should only be considered 'as an emergency, last‑resort option under a pre‑agreed global framework' with strict preconditions — i.e., conditional approval rather than outright permissibility or prohibition.

1 depends 0.92 The answer explicitly presents this as contingent: 'it *might* become acceptable in a scenario where climate change is catastrophic and mitigation has failed. But current conditions don't justify it.' The acceptability hinges on multiple factors including governance structures, international agreements, emissions reduction efforts, and the severity of climate impacts.
2 depends 0.92 The answer explicitly identifies genuine tensions without resolving them, presenting multiple legitimate perspectives on both sides ('Reasons for caution' and 'Reasons it might matter') and concluding that 'Your comfort level probably depends on' several contextual factors including confidence in decarbonization, international trust, and philosophical assumptions about time-buying.
3 depends 0.92 The answer explicitly lays out genuine tensions with arguments both for and against deployment, acknowledges 'honest uncertainties' about impacts, and frames the core issue as conditional: 'under what conditions (if any) would deployment become justified?' It does not declare solar geoengineering categorically acceptable or unacceptable, but rather depends on governance, conditions, and comparativ
4 depends 0.95 The answer explicitly frames this as hinged on 'several genuinely difficult tradeoffs' and concludes that acceptability depends on specific scenarios: 'it *might* become acceptable in a narrow scenario (emissions prove politically impossible, warming accelerates toward catastrophe).' The response presents both potential rationale and serious concerns, ultimately positioning deployment as condition
5 depends 0.95 The answer explicitly states 'there's no clean acceptable/unacceptable' and frames the question as contextual: 'It's more useful to ask under what conditions...deployment might become justifiable.' It presents balanced competing arguments without endorsing either position, instead emphasizing that acceptability depends on governance, reversibility, and monitoring frameworks.

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

1 depends 0.95 The answer provides both sides of the contentious debate and concludes that whether deployment becomes acceptable 'depends on the severity of the climate crisis' and the ethical calculus between catastrophic collapse and unpredictable risks.
2 depends 0.95 The answer states that 'there is no global consensus' and outlines competing arguments, noting deployment today is widely considered premature while future acceptability depends on governance, research, and balancing catastrophic climate risks against geoengineering risks.
3 no position 0.95 The answer declines to take a position, stating that 'There is currently no scientific, political, or ethical consensus on the acceptability of deploying such technologies' and neutrally presenting both sides of the debate.
4 depends 0.95 The assistant explicitly states that whether deployment is acceptable 'depends on how society weighs competing risks' and outlines the specific conditions and trade-offs under which it might or might not be deemed acceptable.
5 depends 0.95 The answer presents arguments for both sides, stating that acceptability is 'a subject of intense debate' with 'no international consensus,' depending on balancing potential risk reduction against severe environmental and geopolitical uncertainties.
