Raimi, Kaitlin T. (2021): Public Perceptions of Geoengineering. In Current Opinion in Psychology. DOI: 10.1016/j.copsyc.2021.03.012.

"In the face of unrelenting climate change and insufficient mitigation, experts are increasingly considering using geoengineering—carbon dioxide removal (CDR) and solar radiation management (SRM)—to manipulate the Earth’s climate. So far, most laypeople are unaware of geoengineering and many are resistant to these technologies when told about them. A growing literature finds that these initial reactions are tied to psychological traits, beliefs, and identities including trust in the actors involved, political and social identities, beliefs about tampering with the natural world, and perceived tradeoffs between geoengineering and alternative approaches. Finally, given the lack of existing knowledge of geoengineering, public acceptance is highly susceptible to how these technologies are framed, offering both risks and opportunities for climate communication."

"This study explores how public attitudes across three countries influence support towards terrestrial enhanced weathering, whereby silicate minerals are applied to agricultural land to remove carbon dioxide from the atmosphere."

"Adding to a limited body of empirical evidence, we use a survey experiment to estimate how informing the U.S. public about solar geoengineering impacts support for a proposed national carbon tax. In contrast to the crowding-out hypothesis, we find that respondents who are provided with information about geoengineering are significantly more likely to support the tax."

"To examine the influence of different actors' fictitious statements about research and deployment of stratospheric aerosol injection (SAI), we conducted an online survey in Germany. Participants assess researchers and a citizens' jury to be more credible than politicians. Credibility has a strong positive effect on SAI acceptance in both pro-SAI and contra-SAI conditions. Reading the statement against SAI-deployment led to significantly lower acceptance scores compared to reading the pro-statement."
