Abstract

Climate intervention technologies such as carbon dioxide removal and solar geoengineering are becoming more actively considered as solutions to global warming. The demographic aspects of the public serve as a core determinant of social vulnerability and the ability for people to cope with, or fail to cope with, exposure to heat waves, air pollution, or disruptions in access to modern energy services. This study examines public preferences for 10 different climate interventions utilizing an original, large-scale, cross-country set of nationally representative surveys in 30 countries. It focuses intently on the demographic dimensions of gender, youth and age, poverty, and income as well as intersections and interactions between these categories. We find that support for the more engineered forms of carbon removal decreases with age. Gender has little effect overall. Those in poverty and the Global South are nearly universally more supportive of climate interventions of various types. Public support for solar geoengineering and carbon dioxide removal methods decreases with age, and gender has little effect overall, according to an analysis combining the survey of 30 844 participants from 30 countries and a statistical approach.

人口结构决定了 30 个国家公众对二氧化碳清除和太阳能地球工程干预措施的偏好
二氧化碳清除和太阳能地球工程等气候干预技术正被更积极地视为解决全球变暖问题的办法。公众的人口结构是决定社会脆弱性以及人们应对或无法应对热浪、空气污染或现代能源服务中断的能力的核心因素。本研究利用在 30 个国家进行的一套原创性、大规模、跨国的全国代表性调查,研究了公众对 10 种不同气候干预措施的偏好。研究重点关注性别、青年和年龄、贫困和收入等人口因素,以及这些因素之间的交叉和相互作用。我们发现,随着年龄的增长,人们对工程化程度较高的碳清除方式的支持度会降低。性别在总体上影响不大。贫困人口和全球南部人口几乎普遍更支持各种类型的气候干预措施。根据对来自 30 个国家的 30 844 名参与者的调查和统计方法的综合分析,公众对太阳能地球工程和二氧化碳清除方法的支持随着年龄的增长而减少,而性别在总体上影响不大。
