随着对气候变化的警告和行动呼吁的加剧，太阳能地球工程（SG）受到越来越多的关注和争议。关于是否应该或是否会使用它的观点分歧，但这些观点的证据基础是薄弱的。在这样一个高风险、知识有限的问题上，人们可能会期望研究得到强有力的支持，但即使是研究也遇到了反对。反对者的反对意见基于合理的担忧，但不可能完全解决，因为他们的框架使拒绝研究成为一种公理，而不是基于证据的结论。
As alarm about climate change and calls for action intensify, solar geoengineering (SG) is seeing increased attention and controversy. Views on whether it should or will ever be used diverge, but the evidentiary basis for these views is thin. On such a high-stakes, knowledge-limited issue, one might expect strong support for research, but even research has met opposition. Opponents’ objections are grounded in valid concerns but impossible to fully address, as they are framed in ways that make rejecting research an axiom, not a conclusion based on evidence.
