Moore, John C.; et al. (2019): Greenland Ice Sheet Response to Stratospheric Aerosol Injection Geoengineering

Moore, John C.; Yue, Chao; Zhao, Liyun; Guo, Xiaoran; Watanabe, Shingo; Ji, Duoying (2019): Greenland Ice Sheet Response to Stratospheric Aerosol Injection Geoengineering. In Earth’s Future 110, p. 25. DOI: 10.1029/2019EF001393.

"We simulated Greenland ice sheet climates using four Earth system models running the stratospheric sulfate aerosol injection experiment GeoMIP G4 and the CMIP RCP4.5 and RCP8.5 greenhouse gas scenarios that were then used to drive the surface energy and mass balance model, SEMIC. Simulated runoff is 20% lower under G4 than RCP4.5, while under RCP8.5 it is 17% higher."

Gizmodo: Geoengineering Wouldn't Be Enough to Stop Greenland From Melting

"The results show that the planet-cooling properties of the particles would extend to Greenland, lowering air temperatures there by about 1.1 degrees Celsius (2 degrees Fahrenheit) compared to the scenarios without geoengineering. Runoff from melt would drop anywhere from 20 to 32 percent, with the biggest difference coming under the high greenhouse gas emissions scenario. All that means sea level rise would slow."

Sugiyama, Masahiro; et al. (2020): The North–South Divide on Public Perceptions of Stratospheric Aerosol Geoengineering?: A Survey in Six Asia-Pacific Countries

Sugiyama, Masahiro, Shinichiro Asayama, and Takanobu Kosugi (2020): The North–South Divide on Public Perceptions of Stratospheric Aerosol Geoengineering?: A Survey in Six Asia-Pacific Countries. Environmental Communication. January 3, 2020. https://www.tandfonline.com/doi/abs/10.1080/17524032.2019.1699137?journalCode=renc20&.

"The present study conducted an online survey of college students in six Asia-Pacific countries (Australia, China, India, Japan, the Philippines, and South Korea) about their attitudes toward stratospheric aerosol geoengineering, one of most discussed SRM proposals. Our results showed that students from the Global South (China, India, the Philippines) were more willing to accept geoengineering as a potential option than those from the Global North (Australia, Japan, and South Korea)."

Merk, Christine; et al. (2019): Public Perceptions of Climate Engineering: Laypersons’ Acceptance at Different Levels of Knowledge and Intensities of Deliberation

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."
