RESEARCH PAPERS
Microphysical Interactions Determine the Effectiveness of Solar Radiation Modification via Stratospheric Solid Particle Injection
Vattioni, S., Käslin, S. K., Dykema, J. A., Beiping, L., Sukhodolov, T., Sedlacek, J., ... & Chiodo, G. (2024). Microphysical interactions determine the effectiveness of solar radiation modification via stratospheric solid particle injection. Geophysical Research Letters, 51(19), e2024GL110575.
Synopsis: In this study, scientists report that shooting 5 million tons of diamond dust into the stratosphere each year could cool the planet by 1.6ºC—enough to stave off the worst consequences of global warming. Moreover, the 3D climate model showed diamond dust could reflect sunlight, remain airborne for a long time and avoid clumping, all while being chemically inert—meaning no acid rain formation. But. the scheme wouldn’t be cheap, however: experts estimate it would cost nearly $200 trillion over the remainder of this century—far more than traditional proposals to use sulfur particles.
Demographics shape public preferences for carbon dioxide removal and solar geoengineering interventions across 30 countries
Sovacool, B. K., Evensen, D., Baum, C. M., Fritz, L., & Low, S. (2024). Demographics shape public preferences for carbon dioxide removal and solar geoengineering interventions across 30 countries. Communications Earth & Environment, 5(1), 642.
Synopsis: Climate intervention survey across 30 countries reveals key demographic divides in preferences for solar geoengineering. Support is generally higher among younger populations and those in poverty, especially in the Global South. Gender has minimal influence, but age, income, and region significantly shape attitudes toward these interventions.
Global perspectives on solar geoengineering: A novel framework for analyzing research in pursuit of effective, inclusive, and just governance
Dove, Z., Hernandez, A., Talati, S., & Jinnah, S. (2024). Global perspectives on solar geoengineering: A novel framework for analyzing research in pursuit of effective, inclusive, and just governance. Energy Research & Social Science, 118, 103779.
Synopsis: A new framework examining research on solar geoengineering (SG) perceptions reveals notable biases: studies largely focus on perspectives from the Global North, underrepresent youth voices, and often aim to increase public support for SG, sidelining other lines of inquiry. Cross-cultural insights, especially on public engagement and capacity building, are frequently overlooked. To address these gaps, recommendations call for more inclusive, justice-centered approaches to enhance SG governance and representation in future studies.
The Development of a Floating Mono-Particle “Sun Shield” to Protect Corals from High Irradiance during Bleaching Conditions
Scofield, J. M., Prime, E. L., Flores, F., Severati, A., Mongin, M., Bougeot, E., ... & Qiao, G. G. (2024). The Development of a Floating Mono-Particle “Sun Shield” to Protect Corals from High Irradiance during Bleaching Conditions. Journal of Marine Science and Engineering, 12(10), 1809.
Synopsis: Coral bleaching is intensifying due to climate change. This study introduced a new “sun shield” technology, using a monolayer of reflective calcium carbonate particles that reduces sunlight by ~20% over coral reefs. Modeling shows this shield could lower bleaching stress across 1.5 km² by cutting reactive oxygen buildup. With further refinement, this method could protect vulnerable reefs during heatwaves, reducing bleaching impact on a small scale.
New submodel for emissions from Explosive Volcanic ERuptions (EVER v1.1) within the Modular Earth Submodel System (MESSy, version 2.55.1)
Kohl, M., Brühl, C., Schallock, J., Tost, H., Jöckel, P., Jost, A., ... & Pozzer, A. (2024). New submodel for emissions from Explosive Volcanic ERuptions (EVER v1. 1) within the Modular Earth Submodel System (MESSy, version 2.55. 1). EGUsphere, 2024, 1-35.
Synopsis: A methodological study introduces EVER v1.1, a submodel for tracer emissions from explosive volcanic eruptions, developed within the Modular Earth Submodel System (MESSy). EVER quantifies gaseous and aerosol tracers based on eruption parameters and facilitates mapping of volcanic ash sizes. Evaluated using the ECHAM/MESSy Atmospheric Model (EMAC) alongside satellite data from the 2011 Nabro eruption, it highlights sensitivities in emission parameters. The study proposes a standardized setup for simulating volcanic impacts on stratospheric SO₂ from 1990 to 2023, with potential applications in volcanic ash, wildfires, and solar geoengineering research.
A new method for diagnosing effective radiative forcing from aerosol-cloud interactions in climate models
Duran, B. M., Wall, C. J., Lutsko, N. J., Michibata, T., Ma, P. L., Qin, Y., ... & Debolskiy, M. (2024). A new method for diagnosing effective radiative forcing from aerosol-cloud interactions in climate models. EGUsphere, 2024, 1-41.
Synopsis: This study introduces a method for estimating shortwave effective radiative forcing from aerosol-cloud interactions (ERFaci) using histograms of cloud fraction, droplet effective radius, and liquid water path. Applied to five CMIP6 models, the method yields total SW ERFaci estimates that align with established techniques. Findings indicate that since 1850, the Twomey effect contributed −0.34 Wm−2, liquid water path adjustments contributed −0.22 Wm−2, and cloud fraction adjustments contributed −0.09 Wm−2. This approach enhances the accuracy of diagnosing ERFaci components, crucial for reducing uncertainty in historical climate forcing estimates.
Change in Wind Renewable Energy Potential Under Stratospheric Aerosol Injections
Baur, S., Sanderson, B. M., Séférian, R., & Terray, L. (2024). Change in Wind Renewable Energy Potential under Stratospheric Aerosol Injections.
Synopsis: This study investigates the impact of Stratospheric Aerosol Injections (SAI) on wind renewable energy (WRE) potential under different emission scenarios. Using the CNRM-ESM2-1 Earth System Model, results indicate that while global WRE potential remains largely unchanged under SAI compared to SSP scenarios, regional variations are significant, with fluctuations reaching ±12% in WRE potential. Notably, SAI modifies large-scale circulation patterns, leading to a pronounced poleward jet shift in the Southern Hemisphere. This research underscores the complex interactions between SRM strategies and wind patterns, informing future mitigation efforts.
Political ideology and views toward solar geoengineering in the United States
Magistro, B., Debnath, R., Ebanks, D., Wennberg, P., & Alvarez, R. M. (2024). Political ideology and views toward solar geoengineering in the United States.
Synopsis: This study explores how familiarity with solar geoengineering (SG) affects political polarization regarding climate change among American voters. Analyzing a nationally representative sample of 2,109 individuals, the findings reveal that greater familiarity with SG correlates with diminished political divides, particularly in support for SG, concerns about its risks, and preferred climate strategies. This suggests that increasing awareness of SG could facilitate bipartisan engagement on climate policy, offering a pathway to overcome ideological barriers in climate action.
Impacts of Solar Geoengineering on Malaria Transmission in South Asia [Preprint]
Hussain, A., Khan, M. A., & Shoaib, M. (2024). Impacts of Solar Geoengineering on Malaria Transmission in South Asia. Authorea Preprints.
Synopsis: This study examines the impact of Solar Geoengineering (SG) on malaria distribution in seven climate-vulnerable South Asian countries. Using Entomological Inoculation Rate (EIR) and Length of Transmission Season (LTS) as indicators, results from a dynamical malaria model show that the G6sulfur SG scenario leads to an overall decrease in malaria distribution from 2020 to 2090 compared to the SSP585 scenario. Significant declines in malaria are projected for Bangladesh, India, and Pakistan, while Afghanistan, Iran, and Nepal show moderate decreases in EIR, indicating a potential positive effect of SG on malaria transmission dynamics in these regions.
Effective control mechanisms of research on climate engineering techniques for the public good – the London Protocol regulatory approach as a role model
Ginzky, H., & Oschlies, A. Effective control mechanisms of research on climate engineering techniques for the public good–the London Protocol regulatory approach as a role model. Frontiers in Climate, 6, 1474993.
Synopsis: This study advocates for the governance of climate engineering techniques, emphasizing the London Protocol as a model for regulating emerging technologies like Carbon Dioxide Removal and Solar Radiation Modification. The authors argue that public funding and appropriate regulatory frameworks are crucial for overseeing in situ research and development. They suggest that the London Protocol’s framework for marine geoengineering could effectively inform governance schemes for other climate engineering approaches, ensuring responsible research and potential deployment.
A model study exploring the decision loop between unilateral stratospheric aerosol injection scenario design and Earth system simulations
Diao, C., Keys, P., Bell, C. M., Barnes, E. A., & Hurrell, J. W. (2024). A model study exploring the decision loop between unilateral stratospheric aerosol injection scenario design and Earth system simulations.
Synopsis: This paper develops a framework integrating unilateral SAI scenario design with geopolitical game theory and Earth system model simulations. Using the Community Earth System Model (CESM), a plausible unilateral SAI initiation scenario is simulated, revealing complex feedback loops between SAI deployment and subsequent climate impacts. The findings underscore the necessity of exploring unilateral SAI scenarios within the context of global cooperation and strategic decision-making.
Impacts of Solar Geoengineering on Projected Climate of South Asia
Hussain, A., Khan, M. A., & Sipra, H. (2024). Impacts of Solar Geoengineering on Projected Climate of South Asia. Authorea Preprints.
Synopsis: Solar geoengineering (SG), specifically stratospheric aerosol injection, is investigated for its potential impacts on temperature and precipitation patterns in climate-vulnerable South Asia. Under the SG G4 scenario, temperatures are projected to decrease by -0.62 °C, showing significant cooling effects during both the implementation phase (2020-2029) and continuation phase (2030-2069). While a cold bias is noted compared to RCP 4.5 projections, precipitation decreases slightly by -0.02 mm/day during the implementation phase, with no significant changes anticipated during the later phases.
Addressing the urgent need for direct climate cooling: Rationale and options
Baiman, R., Clarke, S., Elsworth, C., Field, L., MacCracken, M., Macdonald, J., ... & Tulip, R. (2024). Addressing the urgent need for direct climate cooling: rationale and options. Oxford Open Climate Change, 4(1), kgae014.
Synopsis: This study proposed an integrated approach to combat climate change by emphasizing several key strategies. First, it advocates for the research and deployment of large-scale cooling influences, particularly starting in polar regions, to address immediate temperature increases. In addition, the implementation of local and regional cooling measures that support adaptation efforts is recommended. The authors stress the importance of accelerating emissions reductions, especially targeting short-lived climate pollutants. Finally, they call for enhanced large-scale carbon removal initiatives to draw down legacy greenhouse gases.
Pushing Radiative Cooling Technology to Real Applications
Lin, C., Li, K., Li, M., Dopphoopha, B., Zheng, J., Wang, J., ... & Huang, B. (2024). Pushing Radiative Cooling Technology to Real Applications. Advanced Materials, 2409738.
Synopsis: Radiative cooling technology presents a viable strategy for combating global warming while promoting energy efficiency. Despite progress, five critical challenges hinder its practical application: improving optical efficiency, preserving aesthetic appeal, controlling overcooling effects, enhancing durability, and scaling up manufacturing processes. This review outlines the optical principles of radiative cooling and addresses these challenges, proposing advanced solutions through innovative structural designs, material choices, and fabrication methods, ultimately guiding future research and industry efforts in this field.
Drivers and attitudes of public support for technological solutions to climate change in 30 countries
Brutschin, E., Baum, C. M., Fritz, L., Low, S., Sovacool, B. K., & Riahi, K. (2024). Drivers and attitudes of public support for technological solutions to climate change in 30 countries. Environmental Research Letters, 19(11), 114098.
Synopsis: Public attitudes toward CDR and SRM technologies vary significantly across different countries. Surveys in 30 nations reveal that skepticism is most pronounced in wealthier countries, where trust in science and technology is lower, and personal climate change impacts are perceived as less severe. Conversely, many middle-income countries show higher support for CDR and SRM, despite potentially lacking the capacity for effective implementation. This highlights the need for tailored climate strategies that consider local contexts and emphasize international collaboration and governance to responsibly manage these technologies.
Impact of Solar Radiation Management on Andean glacier-wide surface mass balance
Fernández, A., Manquehual-Cheuque, F., & Somos-Valenzuela, M. (2024). Impact of Solar Radiation Management on Andean glacier-wide surface mass balance. npj Climate and Atmospheric Science, 7(1), 257.
Synopsis: The impact of SRM on the surface mass balance of Andean glaciers examined in this paper reveals a consistent negative mass balance across all climate scenarios analyzed for the 21st century. However, SRM does influence interannual variability and temperature sensitivity in certain regions. Had SRM been adopted in the late 1980s, it could have significantly altered the current negative trends. Given the diverse hydroclimatic regimes present in the Andes, these results underscore the critical need for urgent emissions reductions to preserve these vital ecosystems.
An open letter to the IMO supporting maritime transport that cools the atmosphere while preserving air quality benefits
Baiman, R., Bishop, R., Elsworth, C., Gadian, A., Melton, B., Petersen, O., & Tao, Y. (2024). An open letter to the IMO supporting maritime transport that cools the atmosphere while preserving air quality benefits. Oxford Open Climate Change, 4(1), kgae008.
Synopsis: This open letter highlights a global warming emergency worsened by the decline in anthropogenic atmospheric aerosol levels, particularly due to International Maritime Organization (IMO) regulations on bunker-fuel sulfur oxides. The letter suggests reconsidering these regulations by temporarily relaxing sulfur emissions for "high seas" shipping to enhance cooling benefits while preserving air quality in coastal areas. It advocates for research into benign aerosol alternatives, such as Marine Cloud Brightening and Tropospheric Aerosol Injection, to replace the cooling effects of sulfur emissions without harming humans or ecosystems.

Is cirrus thinning dead? Jeggle | Reviewer 2 does Geoengineering
"Kai Jeggle explains to @geoengineering1 how off-target effects of cirrus cloud thinning mean that it can never be used effectively. Paper; Jeggle, K., Neubauer, D., Binder, H., and Lohmann, U.: Cirrus formation regimes – Data driven identification and quantification of mineral dust effect, EGUsphere [preprint], https://doi.org/10.5194/egusphere-2024-2559, 2024."
Solar Radiation Management's Risks and Opportunities | Climate on the Edge
"In this episode I explore the controversial topic of solar geoengineering with Dr. Holly Jean Buck, and Dr. Will Burns, two of the most thorough and interesting thinkers out there when it comes to the topic. Specifically they talk me through the question of “should we ban SRM research”.
There’s a lot these two experts disagree on about SRM, and their back and forth really expanded my thinking on the topic. Together, we break down what SRM is, how it might work, and the different approaches within SRM, such as stratospheric aerosol injection and marine cloud brightening.
This episode provides a nuanced look at SRM as part of the climate action toolkit, I hope it helps you think critically about the role it might play, as it did for me.”

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."

Has the Atlantic AMOC system ALREADY started to collapse?? | Just Have a Think
"AMOC, or The Atlantic Meridional Overturning Circulation, has collapsed many times in Earth's geological history. But it's never happened while modern civilisations have existed - at least not until now anyway. We're already struggling to cope with 0.2 degrees Celsius of warming each decade, but an AMOC collapse could bring such catastrophic seasonal disruption that it would make recent extreme weather events look like a walk in the park! So, what's the plan??"

SPF 1000: Modifying Solar Radiation SOSV CLIMATE TECH SUMMIT 2024 | SOSV
"Given that global temperatures have hit record highs 13 months in a row, it’s reasonable to ask whether decarbonization can move fast enough. What if extreme weather events produce huge death tolls? One response could be to pump sulfur dioxide into the stratosphere to cool the planet by reflecting the sun’s energy away from earth. Controversial in the extreme, yes, but more than ever the object of well-funded research. Our panel looks at the state of the debate over this extreme climate tech. The speakers are David Keith (University of Chicago) Ryan Orbuch (Lowercarbon Capital) and Janos Pasztor (independent consultant.).The moderator is Cat Clifford, who is a correspondent at Cipher."
