RESEARCH PAPERS
Weakening the CO2 Greenhouse Effect via Stratospheric Aerosol Injection
He, H., Soden, B., Vecchi, G., & Yang, W. (2024). Weakening the CO2 Greenhouse Effect via Stratospheric Aerosol Injection.
Synopsis: Stratospheric aerosol injection is a potential climate modification strategy to offset warming by increasing sunlight reflection. This study proposes a more efficient SAI method using absorptive aerosols in the upper stratosphere (~10 hPa), which weakens the greenhouse effect by enhancing infrared radiation emission. Climate models show that this method leads to a significantly larger temperature reduction compared to traditional reflective aerosols, suggesting further research is needed to assess potential impacts and risks.
Climate Intervention Research in the World Climate Research Programme A Perspective
Hurrell, J. W., Haywood, J. M., Lawrence, P., Lennard, C. J., & Oschlies, A. Climate Intervention Research in the World Climate Research Programme A Perspective. Frontiers in Climate, 6, 1505860.
Synopsis: The 2023 WCRP Open Science Conference highlighted the urgent need for enhanced climate change mitigation, adaptation, and decision-making systems. This perspective emphasizes three climate intervention (CI) approaches—terrestrial carbon dioxide removal (CDR), marine CDR, and solar radiation modification (SRM). With rising greenhouse gas emissions, CI strategies are seen as vital supplements to traditional methods. The paper calls for WCRP to lead in CI research, stressing inclusivity and collaboration with the Global South for a comprehensive, equitable assessment of CI risks and benefits.
Can the Artificial Release of Fluorinated Gases Offset Global Cooling Due to Supervolcanic Eruptions?
Xu Y, Ribar NP, Sachnik J, Schade GW, Lockley AJ, Zhang YG, Yu P, Hu J, Velders GJM. (2024). Can the Artificial Release of Fluorinated Gases Offset Global Cooling Due to Supervolcanic Eruptions? Atmosphere. 15(11):1322.
Synopsis: Large volcanic eruptions can cause abrupt global cooling, posing a significant risk to biodiversity, food production, and human society. This study explores using fluorinated gases (F-gases) to counteract such cooling. Identifying suitable gases like C4F6 and CH3F, the paper suggests these could be released at gigaton scales to offset volcanic cooling. The study discusses the radiative properties, manufacturing constraints, and technical implications of this approach, offering a conceptual framework for mitigating global catastrophic cooling risks.
The Impact of Abrupt Sunlight Reduction Scenarios on Renewable Energy Production
Varne, A. R., Blouin, S., Williams, B. L. M., & Denkenberger, D. (2024). The impact of abrupt sunlight reduction scenarios on renewable energy production. Energies, 17(20), 5147.
Synopsis: This study evaluates the impact of abrupt sunlight reduction scenarios (ASRS), such as nuclear winter or volcanic eruptions, on global renewable energy supply. In a 100% renewable energy scenario, with wind and solar providing 94% of global energy, ASRS could reduce wind and solar generation by 59% in the first year, taking over a decade for full recovery. To meet critical energy needs, international trade and resilient energy sources like geothermal, nuclear, and hydropower would be necessary.
‘Ice sheet conservation’ and international discord: governing (potential) glacial geoengineering in Antarctica
Flamm, P., & Shibata, A. (2024). ‘Ice sheet conservation’and international discord: governing (potential) glacial geoengineering in Antarctica. International Affairs, iiae281.
Synopsis: This study suggests that while artificial infrastructures, such as an undersea "curtain," may offer a potential solution to stabilizing the West Antarctic Ice Sheet and preventing sea-level rise, they carry significant technical, environmental, and governance risks. It argues that such interventions could undermine the principles of the Antarctic Treaty, particularly its emphasis on peaceful use, and could lead to geopolitical conflicts over sovereignty, authority, and security in the region. Therefore, even if technically feasible, the project may not be viable due to these challenges.
Building a comprehensive library of observed Lagrangian trajectories for testing modeled cloud evolution, aerosol-cloud interactions, and marine cloud brightening
Erfani, E., Wood, R., Blossey, P., Doherty, S. J., & Eastman, R. (2024). Building a comprehensive library of observed Lagrangian trajectories for testing modeled cloud evolution, aerosol-cloud interactions, and marine cloud brightening. EGUsphere, 2024, 1-52.
Synopsis: This study investigates marine low clouds' responses to varying environmental conditions by creating a library of over 2200 Lagrangian trajectories in the Northeast Pacific. Using Principal Component Analysis (PCA), two principal components capture 43% of variability in cloud-controlling factors. Large-Eddy Simulations (LES) simulate two distinct cloud cases, revealing that aerosol perturbations delay cloud breakup and enhance radiative effects. The study highlights the sensitivity of cloud responses to precipitation-aerosol feedback and entrainment dynamics.
Projected future changes in extreme precipitation over China under stratospheric aerosol intervention in the UKESM1 climate model
Wang, O., Liang, J., Gu, Y., Haywood, J. M., Chen, Y., Fang, C., & Wang, Q. G. (2024). Projected future changes in extreme precipitation over China under stratospheric aerosol intervention in the UKESM1 climate model. Atmospheric Chemistry and Physics, 24(21), 12355-12373.
Synopsis: This study explores the impact of Stratospheric Aerosol Injection (SAI) on extreme precipitation events in China under global warming, comparing simulations with different emission scenarios (SSP5-8.5, SSP2-4.5) and solar reduction (G6solar). Results indicate that extreme precipitation and wet climate events will increase by 2071–2100. SAI (G6sulfur) and solar reduction (G6solar) show similar effects to SSP2-4.5, with SAI more effectively reducing extreme precipitation. The study calls for further research with broader models to better assess hydrological impacts.
One Atmosphere, Many Metaphysics: The Philosophies of Geoengineering
Pavesi, M. (2024). One Atmosphere, Many Metaphysics: The Philosophies of Geoengineering. Authorea Preprints.
Synopsis: Geoengineering is gaining attention as a potential solution to global warming, though it sparks controversy due to its high risks and uncertainties. This review examines the metaphysical arguments for and against geoengineering, categorizing proponents and opponents into four ideal-types: homo naturans, homo faber, homo sapiens, and anthropo-not-seen. The study also identifies a second division in the debate: transcendental vs. instrumental metaphysics, enriching the understanding of geoengineering's ethical and philosophical implications.
Climate response to interhemispheric differences in radiative forcing governed by shortwave cloud feedbacks
Kaur, H., Bala, G., & Seshadri, A. K. (2024). Climate response to interhemispheric differences in radiative forcing governed by shortwave cloud feedbacks. Environmental Research: Climate.
Synopsis: This study explores climate responses to interhemispheric radiative forcing differences, comparing uniform, northern-hemisphere-only, and southern-hemisphere-only forcing scenarios. Results show greater climate sensitivity when forcing is imposed in the southern hemisphere, primarily due to differences in shortwave cloud feedbacks. The study also examines impacts on tropical circulation, planetary albedo, and land/sea warming contrast, revealing how the Intertropical Convergence Zone shifts toward the hemisphere with stronger forcing. These insights are relevant for solar geoengineering and other radiative forcing agents.
A call for strategic assessments of regional applications of solar radiation management: Exploring the challenges and opportunities from marine cloud brightening and albedo surface modification
Baresi, U., Baum, C. M., Fischer, T. B., Lockie, S., Piggott-McKellar, A., Graham, V., ... & Ristovski, Z. (2025). A call for strategic assessments of regional applications of solar radiation management: Exploring the challenges and opportunities from marine cloud brightening and albedo surface modification. Environmental Impact Assessment Review, 110, 107701.
Synopsis: Technological advancements offer potential climate change interventions, like Solar Radiation Management, but face social, technical, and environmental challenges. This paper focuses on regional SRM strategies, such as Marine Cloud Brightening and Albedo Surface Modification, aimed at protecting ice surfaces. It proposes a policy framework using Strategic Environmental Assessment (SEA), an internationally recognized tool, to guide inclusive, environmentally sustainable SRM decision-making, inspired by the Australian Great Barrier Reef restoration program.
Partisanship overcomes framing in shaping solar geoengineering perceptions: Evidence from a conjoint experiment
Magistro, B., Debnath, R., Wennberg, P. O., & Alvarez, R. M. (2024). Partisanship overcomes framing in shaping solar geoengineering perceptions: Evidence from a conjoint experiment.
Synopsis: Public perceptions of solar geoengineering (SG) as a climate solution are shaped by political polarization in the U.S. A study with 2,000 voters found that partisan alignment with information sources significantly influences trust and support for SG, outweighing message framing effects. Democrats and Republicans trust co-partisan messengers more but maintain policy preferences aligned with their ideologies. These results underscore the role of political identity in shaping attitudes toward emerging climate technologies like SG.
A protocol for model intercomparison of impacts of marine cloud brightening climate intervention
Rasch, P. J., Hirasawa, H., Wu, M., Doherty, S. J., Wood, R., Wang, H., ... & Singh, H. (2024). A protocol for model intercomparison of impacts of Marine Cloud Brightening Climate Intervention. Geoscientific Model Development, 17(21), 7963-7994.
Synopsis: The MCB-REG modeling protocol studies regional climate impacts of marine cloud brightening (MCB), focusing on six cloud-dense regions. It uses simulations to explore responses to aerosol forcing in individual and combined regions, identifying patterns in precipitation, surface temperature, and global cooling. Results from three models (CESM2, E3SMv2, UKESM1) show differing cloud susceptibilities to aerosols but consistent cooling efficiency differences by region, with the Southeast Pacific showing the strongest cooling. Further ensemble studies are recommended.
Disaggregating the Governance Dimensions of Solar Geoengineering
Power, B. L. Disaggregating the Governance Dimensions of Solar Geoengineering.
Synopsis: The governance of solar geoengineering increasingly favors a polycentric approach, combining international structures with national and sub-national governance to reflect diverse perspectives. This paper explores disaggregating governance tasks, aligning them with appropriate levels, and using formal or informal mechanisms. By mapping key governance concerns and institutions, it lays the groundwork for a polycentric framework, enabling smaller regulatory mechanisms to integrate into a globally effective policy regime for solar geoengineering.
Regionally Cooperative Socio-Political Dimensions of SRM Impacts on Malaria for Health Policy Makers in South Asia via Dashboard Development
Hussain, A., Talati, S., Sipra, H., & Waheed, A. Regionally Cooperative Socio-Political Dimensions of SRM Impacts on Malaria for Health Policy Makers in South Asia via Dashboard Development.
Synopsis: This study develops an open-source Web-GIS dashboard for South Asia, integrating temperature, precipitation, and malaria’s Entomological Inoculation Rate (EIR). Using five climate models under SSP5-8.5 and G6sulfur scenarios (2021–2090), the dashboard visualizes climate and health trends, aiding policymakers, scientists, and the public in understanding climate change and climate intervention impacts on vector-borne diseases. It also analyzes Pakistan’s climate and health policies, highlighting gaps and offering insights for integrating SRM into health systems.
Marine emissions of methanethiol increase aerosol cooling in the Southern Ocean
Wohl, C., Villamayor, J., Galí, M., Mahajan, A. S., Fernández, R. P., Cuevas, C. A., ... & Saiz-Lopez, A. (2024). Marine emissions of methanethiol increase aerosol cooling in the Southern Ocean. Science Advances, 10(48), eadq2465.
Synopsis: Ocean-emitted methanethiol (MeSH) plays a significant but previously unquantified role in climate-cooling aerosols, complementing dimethyl sulfide (DMS). Using seawater MeSH data and statistical predictors, researchers mapped global MeSH emissions and integrated them into a chemistry-climate model. MeSH emissions increase sulfate aerosol burden by 30–70% over the Southern Ocean, enhance aerosol cooling, extend DMS lifetime, and improve climate model accuracy in this region, reducing radiative bias in current projections.
Impacts of Geoengineering Through Stratospheric Aerosol Injection on Global Weather Patterns
Al-Qarni, A. (2024). Impacts of Geoengineering Through Stratospheric Aerosol Injection on Global Weather Patterns.
Synopsis: Using advanced climate models, this study shows that equatorial aerosol injections for SAI achieve 97% global coverage within a decade, with a peak temperature reduction of 0.6°C in the first ten years. Sustained injection is needed for stabilization. SAI alters precipitation patterns, reducing tropical rainfall and increasing polar precipitation, highlighting complex atmospheric interactions and the need for further research on long-term impacts and governance.
Scientific models versus power politics: How security expertise reframes solar geoengineering
Corry, O., McLaren, D., & Kornbech, N. (2024). Scientific models versus power politics: How security expertise reframes solar geoengineering. Review of International Studies, 1-20.
Synopsis: Rising greenhouse gas levels challenge Liberal hopes for global climate solutions through science and multilateralism, while Realist approaches highlight power dynamics and irrationality. Realists view solar geoengineering as a "lesser evil" to cool the Earth but focus little on its geopolitical implications. In this study, interviews with security experts reveal three reframings: geoengineering as geopolitical leverage, a source of distrust, and a disinformation risk. These insights expand Realist climate scholarship and highlight risks in pursuing such technologies.
From informal to formal governance of solar radiation management
Brent, K., Simon, M., & McDonald, J. (2024). From informal to formal governance of solar radiation management. Climate Policy, 1-18.
Synopsis: Solar radiation management is a controversial climate intervention, raising governance challenges around risk mitigation, social acceptability, and responsible development. In the absence of formal policies, ten key governance proposals over 15 years identified common principles, such as treating SRM as a public good, ensuring transparency, and conducting impact assessments. While informal frameworks suffice for guiding policymaking, formalizing these principles into research policies and laws is crucial for accountability as SRM research scales up.
Effects of Warming and Stratospheric Aerosol Injection on Tropical Cyclone Distribution and Frequency in a High-Resolution Global Circulation Model
Feder, A., Randall, D., & Dazlich, D. (2024). Effects of Warming and Stratospheric Aerosol Injection on Tropical Cyclone Distribution and Frequency in a High-Resolution Global Circulation Model. EGUsphere, 2024, 1-35.
Synopsis: Advances in global circulation models (GCMs) now allow direct analysis of tropical cyclones (TCs) under future climate scenarios, including climate interventions like Stratospheric Aerosol Injection (SAI). Using high-resolution simulations (30-km grid) and a novel TC-tracking algorithm, this study examines SAI's effects on TCs in scenarios for 2090–2099. Results show SAI can partially restore pre-warming storm patterns but also introduces unique TC distribution changes and potential new hazards.
Reduced winter-time Clear Air Turbulence in the trans-Atlantic region under Stratospheric Aerosol Injection
Barnes, K., Jones, A. C., Williams, P. D., & Haywood, J. M. (2024). Reduced winter-time Clear Air Turbulence in the trans-Atlantic region under Stratospheric Aerosol Injection. Authorea Preprints.
Synopsis: Clear air turbulence (CAT), a major aviation safety concern, is expected to worsen with global warming. Stratospheric aerosol injection (SAI), a climate intervention method, aims to counteract warming but may strengthen the North Atlantic Oscillation (NAO) and jet stream, potentially increasing CAT. Using UKESM1 climate models, researchers found a 23% reduction in severe CAT under SAI compared to a high-warming scenario. SAI's cooling effects outweigh its influence on the NAO, mitigating CAT over the North Atlantic.

Solar Radiation Management to Buy Time for Climate | Climate on the Edge
"As a climate investor focused on energy transition and carbon dioxide removal, I've spent years understanding and supporting technologies that drive decarbonization. But lately I've grown concerned that our progress isn't happening fast enough. The urgency of our situation. Which has become very apparent has left me curious about what else is out there.
That's why I was so excited to speak with Kelly Wanser, Executive Director of SilverLining. SilverLining is a nonprofit organization dedicated to addressing climate risks through advancing research and equitable governance around solar radiation management. Kelly is an absolute powerhouse here and a true pioneer in this field. Our conversation will get into how SRM might work, where it's at today, what's needed to advance the field and why organizations like SilverLining and its backers believe that it should advance.
We'll explore the economic and practical aspects, including concerns about SRM's affordability and the actual, very real logistical challenges of deploying any form of SRM responsibly on a global scale. Kelly is one of the world's most influential figures on SRM and climate intervention beyond emissions reduction. I hope this conversation is as thought-provoking for you as it was for me."

Should we engineer the climate? Nick Breeze interviews Dr Heidi Sevestre and Herb Simmens | ClimateGenn hosted by Nick Breeze
"In this Climategenn episode we hear two committed voices non different sides of the climate engineering debate, make their cases as to why we should or should not research geoengineering with the intention of deployment to cool the Earth.
Dr Heidi Sevestre is an internationally renowned polar scientist making the case against climate engineering (also known as geoengineering) and Herb Simmens is the founder of an international group called the Healthy Planet Action Coalition (HPAC). Both interviews were recorded at COP29 and reflect entrenched positions on both sides of the debate. There are many more voices and we urgently need to hear them - not least from the vulnerable communities who maybe severely impacted by such cooling schemes.
The last word goes to Professor Diana Ürge-Vorsatz, Vice Chair of the IPCC, where she comments on how climate engineering is moving into the main literature advising the United Nations Framework Convention on Climate Change (UNFCCC)."
