太阳能地球工程学试图通过将一小部分太阳光反射回太空来冷却地球，随着气候变化的加剧，它已经引起了科学家和政策制定者的注意。与减缓不同，太阳能地球工程可以快速而廉价地降低全球气温。它也是不完美的。其环境影响仍然不可预测，其低成本和直接影响可能导致“道德风险”，可能会挤出昂贵的缓解努力。人们对公众将如何应对这种权衡几乎一无所知。为了解决这个问题，在2016年11月至11月，作为美国选民合作国会选举研究（CCES）的一部分，进行了一项针对太阳能地球工程的1000名受试者的全国代表性民意调查。个人对太阳能地球工程的速度和成本的重视预示着他们对它的支持，但他们对它的缺点的关注与支持它的研究和使用之间几乎没有关系。默许偏见似乎是围绕太阳能地球工程和道德风险的态度的一个重要因素。
ABSTRACT Solar geoengineering, which seeks to cool the planet by reflecting a small fraction of sunlight back into space, has drawn the attention of scientists and policymakers as climate change remains unabated. Unlike mitigation, solar geoengineering could quickly and cheaply lower global temperatures. It is also imperfect. Its environmental impacts remain unpredictable, and its low cost and immediate effects may result in ‘moral hazard,’ potentially crowding out costly mitigation efforts. There is little understanding about how the public will respond to such tradeoffs. To address this, a 1000-subject nationally representative poll focused on solar geoengineering was conducted as part of the Cooperative Congressional Election Study (CCES) of the US electorate in October–November 2016. The importance that individuals place on solar geoengineering’s speed and cost predicts their support for it, but there is little to no relationship between their concerns about its shortcomings and support for its research and use. Acquiescence bias appears to be an important factor for attitudes around solar geoengineering and moral hazard.
