RESEARCH PAPERS
Solar Geoengineering Effects on Malaria Transmission Risk in South Asia Under G6sulfur Scenario
Authors: Athar Hussain, Muhammad Ali Khan, Muhammad Shoaib
Synopsis: In this study, solar geoengineering (via Stratospheric Aerosol Injection) is assessed for its impact on malaria transmission in South Asia. Using EIR projections, results show a general decline in malaria risk under geoengineering compared to high-emissions scenarios, with the largest reductions in Bangladesh, India, and Pakistan, highlighting potential public health implications of climate intervention.
Impacts of Solar Geoengineering through Stratospheric Aerosol Injection on Terrestrial Ecosystems and Ecosystem Services
Authors: Anna Harper, Christophe Francois, Lili Xia, Maxime Durand, Simone Tilmes, Gabriel Kooperman
Synopsis: Stratospheric Aerosol Injection could cool the planet by mimicking volcanic eruptions, but its ecological impacts remain uncertain. Model-based evidence suggests effects on ecosystems, crops, and carbon cycles via changes in radiation, rainfall, and ozone. Key gaps include limited representation of UV-B impacts, fire feedbacks, and high-latitude ecosystems, highlighting the need for improved, high-resolution Earth system modelling.
Why we need to explore conflict and competition around solar geoengineering
Authors: Ina Möller, Danielle N. Young
Synopsis: In this study, solar geoengineering is reframed not only as a climate response but as a potential instrument of geopolitical power. It emphasizes moving beyond cooperative scenarios to examine conflict and competition, calling for interdisciplinary research to better anticipate risks and inform governance that protects global stability and climate action.
Not yet partisan: Cultural Theory explains attitudes about solar radiation management in the US
Authors: Chris Koski and Paul Manson
Synopsis: In this study, cultural theory is used to explain public attitudes toward SRM in the US. Findings show partisanship is a weak predictor, while cultural values, such as egalitarianism and views on hierarchy, strongly shape support or skepticism. This contrasts with traditional climate policies, where partisanship plays a much larger role.
Could geoengineering ever start? Could it ever stop? Grist for “Destiny Studies” and “Continuity Ethics”
Authors: Robert Socolow
Synopsis: In this study, geoengineering is framed within emerging “Destiny Studies” and “Continuity Ethics,” exploring how humanity governs its long-term future. It examines how geoengineering might begin and end, warning that it could become difficult to stop or even “addictive.” The paper highlights risks of permanent reliance, calling for deeper interdisciplinary thinking on its ethical and societal implications.
A proposal for the safety and controllability requirements that SRM systems should meet
Authors: Eli Waxman, Amyad Spector, Yoav Lederer, Yair Segev, Tzemah Kislev, Yanai Yedvab, Doron Kushnir, and Roby Yahav
Synopsis: In this study, SRM, particularly Stratospheric Aerosol Injection, is assessed through proposed safety and controllability requirements. These criteria aim to guide research and development and support informed policy decisions. The framework offers an initial foundation for evaluating SRM systems and shaping responsible development and potential deployment.
Cloud-Top Relative Humidity Modulates Aerosol Effects Across Marine Cloud Regimes
Authors: Fan Liu, Feiyue Mao, Zengxin Pan, Daniel Rosenfeld, Wei Gong, Lin Zang
Synopsis: Aerosol–cloud interactions offset ~25% of greenhouse warming but remain uncertain due to differing effects of fine and coarse aerosols across cloud regimes. Using satellite and reanalysis data, this study shows fine aerosols strongly enhance cloud cooling, far exceeding sea-salt effects. Responses vary with cloud-top humidity, which controls whether evaporation or precipitation suppression dominates, shaping radiative impacts and cloud water changes.
Climate Engineering: Can Humans Reverse Global Warming?
Authors: Xojabekova Ramzida Uktam qizi
Synopsis: This article examines climate engineering through Carbon Dioxide Removal and Solar Radiation Management, outlining their mechanisms, benefits, and risks. It highlights scientific, ethical, and governance challenges, using real-world case studies. The study concludes these approaches can support, but not replace, emissions cuts, requiring strong global cooperation and responsible oversight.
Drivers of reduced permafrost cooling efficacy of equatorial stratospheric aerosol injection in the Eastern Arctic compared to a moderate emission pathway - Preprint
Authors: Isaline Businger, Rhonda Müller, Raleigh Grysko, Jacqueline Oehri, Jin-Soo Kim, and Gabriela Schaepman-Strub
Synopsis: In this study, SAI is evaluated for its effects on Arctic permafrost under the G6sulfur scenario. While SAI reduces overall warming and slows permafrost loss compared to high-emissions pathways, it alters atmospheric circulation, creating uneven regional impacts—enhancing thaw in some areas while reducing it in others—highlighting risks of unintended spatial consequences.

EGU26S SRM PAPERS
Session AS3.43 - Effect of stratospheric aerosol injection scenarios on surface irradiation and solar energy production
Authors: Kevin Kilchhofer, Kyriaki Papachristopoulou, Manouk Geurts, Timofei Sukhodolov, and Stelios Kazadzis
Synopsis: In this study, the impacts of Stratospheric Aerosol Injection (SAI) on clear-sky surface solar radiation (SSR) are quantified using radiative transfer modeling. Results show modest declines in direct sunlight (3–12%) but a ~40% increase in diffuse radiation, with stronger effects from solid particles. These shifts could affect solar PV performance, highlighting important economic and energy implications of SAI deployment.
JOB OPPORTUNITIES
Operations Specialist, Arctic Stabilization Initiative at Renaissance Philanthropy
“ASI is a 5-year research initiative focused on reducing the risk of catastrophic Arctic climate tipping points — specifically Greenland Ice Sheet melt, Arctic sea-ice loss, and permafrost thaw — systems that are already showing signs of destabilization, with potential cascading impacts on sea levels, weather patterns, and geopolitical stability. Through a stage-gated research process, ASI evaluates potential Arctic-targeted interventions, with an initial focus on Mixed-Phase Cloud Thinning (MCT), to determine whether such approaches could credibly reduce catastrophic risk while building the scientific and governance foundations needed to assess their safety and feasibility.”

Can We Cool The Planet, And Should We Try? | Ep251: Ricken Patel | Cleaning Up Podcast
“What happens if we’re underestimating the speed and scale of climate risk? This week on Cleaning Up, Bryony Worthington sits down with Ricken Patel, Principal at Climate Hub & Founder of activist network Avaaz, to explore how to build successful climate movements, and the case for research into geoengineering.
Ricken argues that companies have been accidentally geoengineering since the turn of the Industrial Revolution, as a byproduct of their pollution, and says ‘it’s crazy’ that research into deliberate forms of geoengineering isn’t being allowed.”
Climate Repair: Hope or Hype? at Cambridge Festival | Centre for Climate Repair
“As global temperatures continue to rise, the idea of “repairing” the climate is capturing public imagination — and stirring controversy. From ocean-based carbon removal to solar radiation management, a host of interventions are being proposed as essential tools to combat climate change, while others warn they are risky distractions from cutting emissions and transforming our energy systems.
This engaging panel discussion will explore the growing field of climate repair and ask whether it represents genuine hope for a cooler planet, or simply the latest hype. Our expert speakers will examine the science behind these technologies, their potential benefits and risks, and the ethical and political questions surrounding their deployment.
With time for audience questions, this session promises an open and lively discussion about one of the most debated topics in climate science today. Whether you are an optimist, a sceptic, or simply curious, Climate Repair: Hope or Hype? invites you to join the conversation and form your own view on repairing our planet.”
Who funds and who pays? How solar geoengineering research is being bankrolled | Hands Off Mother Earth! (HOME) Alliance

SGRP Lunch Talk: Is Politically Feasible and Morally Responsible Geoengineering Possible? | The Salata Institute at Harvard University
“Public and private research on solar geoengineering is on the rise. Nearly all proposals for large-scale research or deployment envision that, given the scale and scope of interventions like stratospheric aerosol injection, some level of international cooperation or coordination is necessary for both success and moral license. Geoengineering more broadly faces the challenge by many opponents that even research, particularly large-scale outdoor experiments, risk “mitigation deterrence” — a moral hazard slowing the commitment to reduce anthropogenic greenhouse gases both by particular countries and under accepted international regimes. Along with the rise in research on geoengineering, there has been a flurry of proposed resolutions and well-organized campaigns in multilateral forums to limit all deployment and some research on solar geoengineering, most prominently advocacy for a global Non-Use Agreement. In this talk, Andrew Light will explore the current landscape of international debates on climate engineering and then try to address the question of whether it is feasible to get sufficient international coordination to attempt some form of climate engineering, and the conditions that would be necessary for some measure of international acceptance of it, as well as the broader problem of how to address the ethical, even existential, challenges to large-scale research or deployment.”
