Injecting sulfate aerosols into the stratosphere could quickly offset global warming caused by anthropogenic greenhouse gas emissions. Because the technology would have global side effects, it raises not only technological but also political, ethical, and social concerns. Therefore, research on sulfate injection should be accompanied by a global debate that incorporates public perceptions and concerns into the development and governance of the technology. Our paper provides insight into public… 

Knowledge about aerosol injection does not reduce individual mitigation efforts

Stratospheric aerosol injection (SAI) is a climate engineering method that is reputed to be very effective in cooling the planet but is also thought to involve major risks and side effects. As a new

Abstract In the rapidly expanding literature on the ethics of climate engineering, a lot has been made of the fact that stratospheric aerosol injection would for the first time create a world whose

The public remain uninformed and wary of climate engineering

International CO 2 emissions reduction commitments are insufficient to avert damaging global warming and imperil a sustainable future. Climate engineering approaches are increasingly proposed as

Southeast Asian expert perceptions of solar radiation management techniques and carbon dioxide removal approaches: caution, ambivalence, risk precaution, and research directions

As the climate crisis intensifies in its impacts, discussions around the deployment of geoengineering solutions in case other interventions fail or prove insufficient have figured in research and

Public perceptions of carbon dioxide removal in the United States and the United Kingdom

Carbon dioxide removal (CDR) technologies may be needed to meet climate change targets. A full understanding of public attitudes towards such approaches is currently lacking. Here we report a

Public perception of climate engineering and carbon capture and storage in Germany: survey evidence

ABSTRACT Climate engineering (CE) and carbon capture and storage are controversial options for addressing climate change. This study compares public perception in Germany of three specific measures:

The North–South Divide on Public Perceptions of Stratospheric Aerosol Geoengineering?: A Survey in Six Asia-Pacific Countries

ABSTRACT Solar radiation management (SRM) is a controversial technological proposal to deliberately cool the Earth for addressing climate change. Because of great concerns over global consequences of

Informed and Uninformed Opinions on New Measures to Address Climate Change

Climate engineering (CE) and carbon capture and storage sub-seabed (CCS-S) are currently controversially debated options to address climate change. Our paper provides empirical evidence on the public

Beliefs and values explain international differences in perception of solar radiation management: insights from a cross-country survey

Solar radiation management (SRM) aims to counteract the negative consequences of global warming and is considered for deployment in the event that mitigation and adaptation efforts appear



Exploring early public responses to geoengineering

Preliminary evidence on public responses to geoengineering from two of the very first UK studies of public perceptions and responses is presented, and it is concluded that public perceptions are likely to prove a key element influencing the debate over questions of the acceptability of geoengineering proposals.

Public understanding of solar radiation management

We report the results of the first large-scale international survey of public perception of geoengineering and solar radiation management (SRM). Our sample of 3105 individuals in the United States,

Deliberating stratospheric aerosols for climate geoengineering and the SPICE project

Increasing concerns about the narrowing window for averting dangerous climate change have prompted calls for research into geoengineering, alongside dialogue with the public regarding this as a

Geoengineering the Climate: Science, Governance and Uncertainty

Geoengineering, or the deliberate large-scale manipulation of the planetary environment to counteract anthropogenic climate change, has been suggested as a new potential tool for addressing climate

Albedo Enhancement by Stratospheric Sulfur Injections: A Contribution to Resolve a Policy Dilemma?

Fossil fuel burning releases about 25 Pg of CO2 per year into the atmosphere, which leads to global warming (Prentice et al., 2001). However, it also emits 55 Tg S as SO2 per year (Stern, 2005),

On the regulation of geoengineering

New evidence that the climate system may be especially sensitive to the build-up of greenhouse gases and that humans are doing a poor job of controlling their effluent has animated discussions around

The Real Economics of Climate Engineering

In 2008 Scott Barrett wrote a paper on “The incredible economics of geoengineering” in which he argued that the potentially low cost of climate engineering (CE) measures together with the quick

Perceptions of geoengineering: public attitudes, stakeholder perspectives, and the challenge of ‘upstream’ engagement

Geoengineering—the deliberate large‐scale manipulation of the planetary environment to counteract anthropogenic climate change—is receiving an increasing amount of attention from academics, policy
