Solar geoengineering (also known as solar radiation modification) is garnering more attention (and controversy) among media and policymakers in response to the impacts of climate change. Such debates have become more prominent following the first-ever field trials of stratospheric aerosol injection (SAI) in 2022. How the lay public perceives solar geoengineering remains unclear, however. We use nationally representative samples ( = 3013) in Mexico, United States, and United Kingdom to examine public perceptions of risks and benefits, support, and policy preferences. We also employ an information-framing design that presented individuals with media-style reports on SAI activities differing along three dimensions: location, actor, and scale and purpose. Support for SAI is found to be generally higher in Mexico; perceptions of risks and benefits do not differ between countries. Information about SAI activities has a limited effect. There is evidence that activities conducted by universities receive more support than those by start-up companies.
太阳能地球工程（也称为太阳辐射改造）因气候变化的影响而在媒体和政策制定者中受到越来越多的关注（以及争议）。在2022年首次进行平流层气溶胶注入（SAI）实地试验之后，此类辩论变得更加突出。然而，普通公众如何看待太阳能地球工程仍不清楚。我们使用墨西哥、美国和英国具有全国代表性的样本（n = 3013）来研究公众对风险与益处、支持度以及政策偏好的看法。我们还采用了一种信息框架设计，向个体展示关于SAI活动的媒体风格报道，这些报道在三个维度上有所不同：地点、行为主体以及规模和目的。结果发现，墨西哥对SAI的支持普遍较高；各国对风险和益处的看法没有差异。关于SAI活动的信息影响有限。有证据表明，大学开展的活动比初创公司开展的活动获得更多支持。
