太阳辐射管理（SRM）已被提议作为减少全球变暖风险的潜在方法。然而，人们普遍担心，SRM 不会均匀地扭转全球变暖的气候后果，从而导致对温室气体 (GHG) 浓度升高和 SRM 综合气候响应的区域差异。最近的研究利用气候模型预测来定量评估区域差异如何影响全球可持续资源管理的整体效率，以及由此产生的可持续资源管理合作和冲突的潜力。初步结果表明，区域差异虽然存在，但可能并不严重。这些评估基于这样的假设：对于所有地区来说，任何偏离过去气候状态的行为都会造成损害。我们通过证明不同的偏好不仅是合理的，而且还有可能大大改变对区域差异的评估，来挑战这种强烈的“改变是坏事”的假设。我们认为，目前的评估几乎没有提供有关 SRM 的道德和政治影响的信息，不同的偏好应该受到更多关注。未来研究的有希望的方向包括弥合一般气候影响研究和环境变化社会影响研究的差距。
Solar radiation management (SRM) has been proposed as a potential method for reducing risks from global warming. However, a widely held concern is that SRM will not reverse the climate consequences of global warming evenly, resulting in regional disparities in the combined climate response to elevated greenhouse gas (GHG) concentrations and SRM. Recent research has used climate model projections to quantitatively assess how regional disparities affect the overall efficiency of global SRM and what the resulting potential for cooperation and conflict with regard to SRM may be. First results indicate that regional disparities, although present, may not be severe. These assessments rest on the assumption that, for all regions, any deviation from a past climate state inflicts damages. We challenge this strong change-is-bad assumption by showing that diverging preferences are not only plausible, but may also have the potential to substantially alter assessments of regional disparities. We argue that current assessments yield little information on the ethical and political implications of SRM and that diverging preferences should receive more attention. Promising directions for future inquiry include bridging gaps to the general climate impact research and to research on the social implications of environmental change.
