Exposure to climate change information predicts public support for solar geoengineering in Singapore and the United States

Abstract

Solar geoengineering is a controversial climate policy measure that could lower global temperature by increasing the amount of light reflected by the Earth. As scientists and policymakers increasingly consider this idea, an understanding of the level and drivers of public support for its research and potential deployment will be key. This study focuses on the role of climate change information in public support for research and deployment of stratospheric aerosol injection (SAI) in Singapore (n = 503) and the United States (n = 505). Findings were consistent with the idea that exposure to information underlies support for research and deployment. That finding was stronger in the United States, where climate change is a more contentious issue, than in Singapore. Cost concern was negatively related to support for funding and perceived risk was negatively related to support for deployment. Perceived government efficacy was a more positive predictor of support for funding in Singapore than in the United States. Additionally, relatively low support for local deployment was consistent with a NIMBY mindset. This was the first study to quantify the role of climate change information in SAI policy support, which has practical implications for using the media and interpersonal channels to communicate about SAI policy measures.

Reflective Boundary Conditions Coupled With the SPH Method for the Three-Dimensional Simulation of Fluid-Structure Interaction With Solid Boundaries

“…Solar geoengineering applies reflective techniques (between particles or between particles and contours) intending to control global warming. Placing solar reflectors in space, injecting reflective particles (aerosols) into the stratosphere, or seeding clouds are attempts to reflect a small fraction of sunlight away from Earth [32][33][34][35][36][37][38]. To this date, the algorithm utilised to perform the solar reflections has not been disclosed in any scientific journal.…”
