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."

"Therefore, the main objective of this meta-analysis was to investigate the effect of BMPs, such as organic amendments, conservation tillage, and cover cropping, on soil health within organic farming systems. We focused on two principal soil health metrics: soil organic carbon (SOC) and microbial biomass carbon (MBC) concentrations."

"Here we synthesized data from 108 eCO₂ experiments and found that the effect of eCO₂ on SOC stocks is best explained by a negative relationship with plant biomass: when plant biomass is strongly stimulated by eCO₂, SOC storage declines; conversely, when biomass is weakly stimulated, SOC storage increases."

"By leveraging year-to-year variation in growing-season cloud optical thickness, I provide nonlinear empirical estimates of how increased atmospheric opacity alters sunlight across the Earth’s surface and how this affects maize and soy yields in the United States, Europe, Brazil and China."
