Merk, Christine, Geraldine Klaus, Julia Pohlers, Andreas Ernst, Konrad Ott, and Katrin Rehdanz (2019): Public Perceptions of Climate Engineering: Laypersons’ Acceptance at Different Levels of Knowledge and Intensities of Deliberation. GAIA - Ecological Perspectives for Science and Society 28 (4): 348–55. https://doi.org/10.14512/gaia.28.4.6.

"‌We look at laypersons’ perceptions of BECCS and SAI at three stylized stages of increasing knowledge and deliberation. We found a high level of uncertainty among survey respondents as to whether to accept the use of these methods, which decreases when additional information is supplied by stakeholders."

"Our latest national survey finds that the highest percentage of Americans since our surveys began are “extremely” or “very” sure global warming is happening. Additionally, an increasing percentage of Americans understand that most scientists think global warming is happening. The report includes many other interesting findings, including how often Americans hear and talk about global warming."

"This paper identifies critical lessons from the climate change experience to guide how communications and engagement on negative emissions can be conducted to encourage functional public and policy discourse. Negative emissions technologies present a significant opportunity for limiting climate change, and are likely to be necessary to keep warming below 2°C."

"As a student at Harvard College studying Environmental Science and Public Policy, I wrote my senior thesis about public opinion on SCoPEx. With funding from Harvard’s Weatherhead Center for International Affairs,[2] I conducted deliberative workshops with Boston and Cambridge residents to explore public perception of SCoPEx and solar geoengineering more broadly. It is worth noting that the sample size for my study was quite small: the initial focus group involved four participants, and the subsequent deliberative workshops had five participants each for a total of twenty people. This was due to temporal and monetary constraints; participants were compensated at $15 per hour. Thus, the findings included here are tentative and meant to serve more as guidance for future research than definitive answers about public opinion on SCoPEx."
