Summary: Research reveals public opposition to geoengineering technologies, particularly conspiracy theories surrounding chemtrails. These theories influence public reactions and regional debates in the UK, USA, India, and Sweden, connecting with broader political considerations. Positive emotions increase following SRM governance events, while negative and neutral emotions rise with SRM projects and experiment announcements. Online toxicity also shapes the spread of anti-SRM views.

Summary: As carbon dioxide concentrations continue to increase and climate change becomes more severe, geoengineering has become an important topic of discussion. Solar geoengineering, which involves reflecting a portion of incoming sunlight, has the potential to quickly cool the planet, but its effects on regional climate patterns, particularly hydrological patterns, are uncertain. This review examines recent studies on the projected hydrologic outcomes of solar geoengineering, taking into account existing literature on hydrological responses to climate change. While most solar geoengineering approaches are expected to weaken the global hydrologic cycle, the specific regional effects will vary depending on the method and strategy of implementation. The findings highlight the importance of considering social conditions and objectives when interpreting the implications of geoengineering on human welfare. Suggestions are made for reducing uncertainties in decision-making in this emerging field of Earth science inquiry.

Summary: Solar geoengineering, such as stratospheric aerosol injection (SAI), aims to mitigate climate change by reflecting sunlight away. This review examines the impacts of SAI on polar climate and cryosphere, emphasizing the need for future research in these areas. Utilizing SAI could cool and stabilize the polar regions under future warming scenarios, but there may be limitations in preventing winter-time polar climate changes and sea-level rise from the Antarctic ice sheet. Other solar geoengineering proposals targeting the poles, such as marine cloud brightening and cirrus cloud thinning, require further investigation to determine their effectiveness. A robust understanding of solar geoengineering's consequences in the polar regions is crucial for informing climate policy.

Summary: Volcano geoengineering is the practice of altering volcanic systems or eruptions to exploit or mitigate their risk. It is technically feasible but currently the risks and uncertainties are too great to justify its use in the short term. However, research into its efficacy and safety is necessary due to its potential large benefits.

Summary: After years of failure to meet carbon reduction goals, it is argued that global climate policies have set unrealistic standards to address climate change. Non-compliance with frameworks like the Paris Agreement suggests that these frameworks were too optimistic about the motivation of signees to take action. One proposed solution to this impasse is geoengineering, seen as a techno-fix that relieves signees and other actors of their mitigation duties. This paper examines different approaches to climate mitigation and argues that the difference lies in perceptions of feasibility rather than fundamental theories of climate justice.

Summary: This paper examines the possibility and challenges of using geoengineering in the service of ecological security. The author argues that while it is possible to incorporate geoengineering into ecological security, extensive research support and a commitment to precaution, humility, reflexivity, and dialogue are crucial.

Summary: This study examines the impact of national governance and policy uncertainty on corporate investment decisions from a sustainable perspective. The findings suggest that national governance has a positive effect on firm investment, while climate and migration policy uncertainty have a negative impact. Moreover, superior environmental, social, and governance performance can help alleviate the burden of debt overhang on firm investment.

Summary: The study found that under global warming scenario, the Indian monsoon circulation and precipitation will strengthen, while under solar geoengineering scenario, although surface cooling is projected, there will be excessive precipitation near the Western Ghats leading to drought bias in most areas of India.

Summary: Volcano geoengineering is the practice of altering volcanic systems and eruptions for exploitation or risk mitigation. Past interventions show it is technically feasible, and economic, political, and environmental pressures may lead to its increased use. However, safety, ethical, and governance concerns need to be addressed before it can be considered viable.

Summary: As social scientists, we are concerned about the impact of the National Academies Report on solar geoengineering, which has initiated a major federal research program in the US. We emphasize the need for international perspectives and governance before proceeding with research and development, as scientists and researchers are not decision-makers for deployment.

Summary: As the global community struggles to meet carbon emission goals and climate-related disaster becomes more likely, geoengineering technologies are being considered as a possible defense against global warming. The Arctic, given its importance in future global climate dynamics, has become a focus for prospective geoengineering efforts. However, in the near future, the regional actors in the Arctic have little incentive to use geoengineering to preserve the region.

Summary: The effectiveness of municipal climate change mitigation policies relies on regional coordination among local governments. However, coordination beyond network participation and information sharing is rare in climate policies. This study investigates formal horizontal policy coordination among local governments and examines multi-government coordination in implementing Community Choice Aggregation (CCA), an impactful climate policy in California. The study evaluates the characteristics and governance structures of CCA programs in the state and conducts in-depth analysis in three regional areas through interviews, media coverage, and decision-making outcomes. The study identifies successful strategies and demonstrates that formal horizontal policy coordination is crucial for local governments in enacting ambitious climate policies in multilevel governance systems.

Summary: This study identifies and assesses uncertainties in the transboundary water governance context by analyzing policy documents in two complex transboundary cases: the Great Lakes and Rio Grande/Bravo basins. The findings reveal deep uncertainties in both cases, with different combinations and interactions between uncertainties. The governance system itself is a significant source of uncertainty in both basins, exacerbating existing uncertainties. Policy responses need to be tailored to address different sources, types, and levels of uncertainty and move towards a monitor-and-adapt governance approach.

Summary: This study investigates the potential impacts of climate intervention on the Indonesian Maritime Continent, finding that artificial intervention can mitigate extreme temperatures. Overall, intervention has a more significant effect on land areas, particularly in the southern monsoon region.
