Sovacool *06 March 2024* *Abstract* Novel, potentially radical climate intervention technologies like carbon dioxide removal and solar geoengineering are attracting attention as the adverse impacts of climate change are increasingly felt. The ability of publics, particularly in the Global South, to participate in discussions about research, policy, and deployment is restricted amidst a lack of familiarity and engagement. Drawing on a large-scale, cross-country exercise of nationally representative surveys (N = 30,284) in 30 countries and 19 languages, this article establishes the first global baseline of public perceptions of climate-intervention technologies. Here, we show that Global South publics are significantly more favorable about potential benefits and express greater support for climate-intervention technologies. The younger age and level of climate urgency and vulnerability of these publics emerge as key explanatory variables, particularly for solar geoengineering. Conversely, Global South publics express greater concern that climate-intervention technologies could undermine climate-mitigation efforts, and that solar geoengineering could promote an unequal distribution of risks between poor and rich countries. Geographic outline of 30 countries surveyed on climate-intervention technologies. [image: figure 1] <https://www.nature.com/articles/s41467-024-46341-5/figures/1> Nationally representative surveys of the public perceptions of climate-intervention technologies were conducted in 30 countries and 19 languages (with at least 1000 participants for each country). Survey samples were nationally representative in terms of age (between 18 and 74), gender, and geographic region and with broad quotas for education and income; Source: Authors. Significant differences between perceptions of risks and benefits in Global South versus Global North countries, grouped by technology category (bolded font indicates significant difference (*p* < 0.05) between perceptions in Global South and Global North; 1–7 scale: 1 = Strongly disagree, 4 = Neither agree nor disagree, 7 = Strongly agree; color scheme shifts from redder to greener as perceived benefits increase and perceived risks decrease). [image: figure 3] <https://www.nature.com/articles/s41467-024-46341-5/figures/3> Greater Support for Climate Intervention Technologies in Global South versus Global North Countries (1-5 scale: 1 = Strictly reject; 3 = Neither support nor reject; 5 = Fully support; bolded font indicates significant difference (*p* < 0.05) between Global South and Global North; color scheme shifts from redder to greener as support for technology increases).
