This article identifies diverse rationales to call for anticipatory governance of solar geoengineering, in light of a climate crisis. In focusing on governance rationales, we step back from proliferating debates in the literature on 'how, when, whom, and where' to govern, to address the important prior question of why govern solar geoengineering in the first place: to restrict or enable its further consideration? We link these opposing rationales to contrasting underlying visions of a future impacted by climate change. These visions see the future as either more or less threatening, depending upon whether it includes the possible future use of solar geoengineering. Our analysis links these contrasting visions and governance rationales to existing governance proposals in the literature. In doing so, we illustrate why some proposals differ so significantly, while also showing that similar-sounding proposals may emanate from quite distinct rationales and thus advance different ends, depending upon how they are designed in practice.

太阳能地球工程的预期治理：对未来的相互矛盾的愿景及其与治理建议的联系。

鉴于气候危机，本文确定了呼吁对太阳能地球工程进行预期治理的各种理由。在关注治理原理时，我们从文献中关于“如何、何时、谁和在哪里”进行治理的激增辩论中退一步，来解决为什么首先要治理太阳能地球工程的重要先验问题：限制或启用其进一步考虑？我们将这些相反的理由与受气候变化影响的未来的对比基本愿景联系起来。这些愿景认为未来或多或少具有威胁性，具体取决于它是否包括未来可能使用的太阳能地球工程。我们的分析将这些截然不同的愿景和治理原理与文献中现有的治理建议联系起来。在这样做，
