TOP 10 SRM UPDATES FROM FEBRUARY 2026
New Platform Launches to Implement Governance Principles for Solar Geoengineering Research
The Alliance for Just Deliberation on Solar Geoengineering, Natural Resources Defense Council, American Geophysical Union and Council on Energy, Environment and Water have launched the Solar Geoengineering Research Governance (SGRG) Platform to enhance transparency and oversight in solar geoengineering research.
The voluntary initiative will develop shared governance tools, including a Research Governance Charter and public disclosure systems, to build trust and consistent norms as SRM research expands. Initially formed by four organizations, the platform aims to broaden participation to institutions across regions and sectors, including laboratories and universities, and collaborate with the Advanced Research and Invention Agency (ARIA), the major government entity located in the UK funding SRM research. An official launch is planned for July 2026.
A Nordic Perspective on AMOC Tipping and the Role of Climate Intervention
The Nordic Council of Ministers has released a report on the risk of an Atlantic Meridional Overturning Circulation (AMOC) tipping point, warning of major climate and socio-economic impacts for Northern Europe. It calls for expanded research on climate intervention technologies alongside decarbonization and net-negative targets, urging stronger monitoring, preparedness and international governance frameworks in the context of AMOC risk.
Climate Intervention at High Latitudes - A 2030 Security Scenario
A new report by the Council on Strategic Risks presents a 2030 scenario in which high-latitude climate intervention, such as Arctic stratospheric aerosol injection, is pursued amid accelerating warming. It examines how unilateral action, geopolitical rivalry, scientific uncertainty and weak governance could heighten security tensions. The analysis highlights risks of escalation, misinformation and mistrust, urging early diplomacy, transparency and international oversight mechanisms.
Open Letter in Support of Applied-Science Testing and Piloting of Near-term Global Climate Cooling Approaches
Healthy Planet Action Coalition (HPAC) is inviting researchers and experts to co-sign an open letter urging support for applied-science testing and piloting of near-term global climate cooling approaches. The letter argues that to prepare options for “shaving the peak” warming between 2030-50, testing and piloting of climate cooling techniques like solar radiation management must begin now alongside emissions cuts and carbon removal. It pushes back against moratorium calls and seeks broader backing before submission to bodies like the IPCC ahead of COP-31.
The Degrees Initiative Expands SRM Research Grants in Global South
The Degrees Initiative has launched Expansion Grants to strengthen Solar Radiation Modification science leadership in the Global South. The program offers larger, longer-term funding of up to £200,000 per grant over 30 months to help established modelling teams deepen SRM research and mentor new scientists. Applications close 24 March 2026.
Ocean Visions Awards New Funding for Research on Arctic Geoengineering Ocean Visions has awarded funding to six projects through its Arctic Sea Ice Restoration Research Fund, exploring approaches to slow or reverse summer sea ice loss, including marine cloud brightening and mixed-phase cloud thinning.
US Watchdog Urges Stronger Oversight of Weather Modification Activities
A new US Government Accountability Office (GAO) report said the National Oceanic and Atmospheric Administration must strengthen its oversight of U.S. weather modification activities, including cloud seeding and “emerging” solar geoengineering work (GAO legally treated SRM as weather modification under the 1972 reporting law). The watchdog found NOAA’s documentation and monitoring of projects are inconsistent and its database incomplete, and recommends clearer guidance, better reporting instructions and regular outreach to operators and local agencies. NOAA agreed with the recommendations.
Environmental Defense Fund Announces First Grantees in SRM Research Program
Environmental Defense Fund has announced the first batch of grantees under its new Solar Radiation Modification research program, awarding nine one-year projects to study potential impacts of stratospheric aerosol injection (SAI) on ecosystems, agriculture and water resources. The research will use past natural analogs like wildfires and volcanic eruptions to inform understanding of how reflective particles might affect light, crop yields, water availability and ecological productivity. EDF says the findings will help policymakers evaluate possible SRM effects with open, publicly available data.
Thwaites Glacier Underwater Barrier Plan
Scientists behind the Seabed Curtain Project have proposed building an 80-km, 150-m-tall underwater wall on the seabed off Thwaites Glacier, often called the “Doomsday Glacier, to block warm ocean water that is accelerating the melting of glacier from below. The geoengineering idea aims to slow sea-level rise that could reach ~65 cm if Thwaites collapses.
Last month, researchers travelled to Antarctica to collect field data, drilling nearly 1 km into the ice of Thwaites Glacier to install instruments and sensors that will transmit daily satellite data for a year to monitor how warm water is eroding the glacier’s base. Early pilot devices are already sending useful data despite some deployment challenges, helping scientists refine the project design. The team also plans further technology testing in the fjords of Norway as part of a multi-year research programme. Hear from project co-lead Marianne Hagen on whether this technology could realistically work.
DSG and CEyD Launch Climate Ethics and Climate Intervention Certificate Program in Argentina
The Alliance for Just Deliberation on Solar Geoengineering has collaborated with Climate Ethics and Development Foundation on Argentina’s University Certificate Program in Climate Ethics for Local Management and Development at the National University of Cordoba Córdoba. This program will equip government officials, civil society leaders, educators, and professionals across Argentina with the tools to engage critically with climate ethics and decision-making, bringing global debates on climate intervention to the local governance level.
For a full recap of last month’s updates, check out our weekly summaries: WEEK 1 | WEEK 2 | WEEK 3 | WEEK 4
And here’s an overview:
RESEARCH PAPERS & THESES
South America monsoon lifecycle under SAI and no-SAI scenarios in a warming world | Authors: João Gabriel Martins Ribeiro, Michelle Simões Reboita & Daniele Visioni
CMIP6 models project that global warming delays South American Monsoon onset and shortens the rainy season, while Stratospheric Aerosol Injection (SAI) preserves historical timing but fails to restore monsoon intensity.
Reduction of Global Sulfate Aerosol Concentration and Corresponding Radiative Effects From Recent Chinese SO2 Emission Reduction | Authors: Warren P. Smith, Simone Tilmes, Benjamin Gaubert, et al.
This study shows that declining Chinese SO₂ emissions (2010–2020) reduced upper-tropospheric sulfate aerosols by up to >20%, increasing global net radiative forcing by ~0.10–0.15 W m⁻², with pronounced regional impacts.
Why do people embrace renewable and sustainable energy technologies for mitigation and geoengineering for adaptation? Explore norms, emotions, and attitudes driving social acceptance | Authors: Milani Alessandro, Dessi Federica, Bonaiuto Marino
Public acceptance of geoengineering and renewable energy is driven mainly by personal and social norms and affective risk–benefit perceptions, with geoengineering support linked to perceived necessity and renewables shaped by more complex emotional responses, this study finds.
Potential impacts of stratospheric aerosol injection on crop yields and related economic outcomes in Africa | Authors: Rhoda Fiyinfoluwa Ayedun, Babatunde J Abiodun and Lili Xia
This study finds that under SSP2-4.5, warming lowers African maize and millet yields, while SAI partially offsets temperature-driven losses - especially in West Africa - but rainfall shifts create regional disparities and do not replace mitigation or adaptation.
Effects of Warming and Stratospheric Aerosol Injection on Tropical Cyclone Distribution and Frequency: Results From a High-Resolution Global Circulation Model | Authors: Andrew Feder, David Randall, Donald Dazlich
High-resolution simulations show SAI could restore global tropical cyclone counts under SSP5-8.5 warming, but significant regional shifts in storm frequency and intensity would still occur.
Solar Geoengineering: Protecting Democratic Deliberations in a Contested Information Environment | Authors: Trish Lavery
This study shows that solar geoengineering’s complexity and governance uncertainty make it vulnerable to disinformation campaigns that could distort democratic debate, underscoring the need for strategic communications to protect evidence-based deliberation.
Marine cloud brightening mitigates the warming induced by the aerosol reductions toward carbon neutrality | Authors: Yang Yu, Yang Yang, Hailong Wang, Lynn M. Russell, et al.
This study finds that marine cloud brightening could offset warming from declining aerosols and stabilize global climate near 2020 levels, but regional warming persists due to circulation changes, highlighting location-sensitive risks.
Aerosol-Cloud Interactions: Overcoming a Barrier to Projecting Near-Term Climate Evolution and Risk | Authors: Ulas Im, Bjørn H. Samset, Athanasios Nenes, Jennie L. Thomas, et al.
Aerosol–cloud interactions remain poorly constrained, and the study calls for improved observations and modeling to better predict near-term warming and guide climate policy.
The Liability of Greenhouse Gas Emitters for Harm Due to Solar Geoengineering | Authors: Mac Willners
This article argues that liability for solar geoengineering harms should be shared by greenhouse gas emitters under an “Emitter Pays Principle,” rather than borne solely by deployers under the Polluter Pays Principle.
The effect of particle shape on shortwave radiative forcing in stratospheric aerosol injection | Authors: Benjamin Vennes, Thomas C. Preston
This study finds that particle shape has little effect on SAI performance, with albedo enhancement driven mainly by particle size and refractive index.
Middle atmosphere chemical and dynamical effects in the CCMI-2022 stratospheric aerosol injection scenario - Preprint | Authors: Andrin Jörimann, Timofei Sukhodolov, Simone Tilmes, et al.
This CCMI-2022 multi-model study finds that SAI causes modest global ozone losses and circulation-driven redistribution, with nonlinear chemistry–dynamics feedbacks contributing to model uncertainty.
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, et al.
This study finds that SAI slows Arctic permafrost loss but shifts circulation and climate patterns, causing regional thaw disparities and preserving less permafrost than a moderate mitigation pathway (SSP2-4.5).
Investigating the relationship between El Niño Southern Oscillation and cirrus clouds - Preprint | Authors: Ehsan Erfani
Using 30+ years of satellite data, the study finds ENSO-driven changes in convection and atmospheric conditions significantly modify cirrus cloud properties and their climate effects.
Stratospheric aerosol forcing for CMIP7 (part 2): Volcanic sulfur dioxide emissions - Preprint | Authors: Thomas J. Aubry, Michael Sigl, Matthew Toohey, et al.
This study introduces a new CMIP7 volcanic sulfur emissions inventory (1750–2023) that improves representation of eruption magnitude, height, and location, enabling more accurate climate and aerosol modeling.
Coral reef exposure increases aerosol and cloud condensation nuclei over the Great Barrier Reef - Preprint | Authors: Juha Sulo, Magdalena Okuljar, Joel Alroe, Zijun Li, et al.
This study shows that coral reefs in the Great Barrier Reef can locally increase ultrafine aerosol particles, while overall aerosol and cloud condensation nuclei levels remain dominated by transported marine aerosols.
Atmospheric Intra-vention : Reimagining Solar Geoengineering Through Feminist New Materialism - Thesis | Author: Pokela, Anni
This thesis reframes feminist critiques of SAI through agential realism and speculative feminism, proposing “climate intra-vention” as an ethical framework for engaging with planetary climate processes.

JOB OPPORTUNITIES
Programme Officer – Latin America and the Caribbean at The Degrees Initiative | Deadline: 26 March 2026
“The Degrees Initiative is a UK-based NGO that strengthens the capacity of the Global South to evaluate SRM, a controversial proposal for reducing some impacts of climate change by reflecting sunlight away from the Earth.”
Research Fellow in Earth System Modelling at University of Leeds
“University of Leeds is seeking a postdoctoral research scientist to work within the ARIA-funded, multi-centre project PROMOTE (Progressing Earth System Modelling for Tipping Point Early Warning Systems). The successful candidate will join the UKESM core team, contributing to the development, evaluation, and application of a new hybrid-resolution version of the 2nd UK Earth system model (UKESM2). The key aim of PROMOTE is to develop and apply a high-resolution ESM to investigate the risks, consequences, and potential interactions between abrupt changes in the North Atlantic subpolar gyre (SPG) and the Greenland ice sheet. The resulting modelling system may act as an early-warning system for abrupt change in both phenomena.”
Department Assistant at Climate Systems Engineering Administration
“The Climate Systems Engineering initiative (CSEi) is a new university-wide research effort seeded in the Physical Sciences Division (PSD) and part of a larger climate and energy focus at the University of Chicago, anchored in the Institute for Climate and Sustainable Growth (the Institute). CSEi addresses the science, engineering, and policy of new technologies to reduce or reverse the harms from accumulated greenhouse gasses, including open-systems carbon removal, solar geoengineering, and local interventions to slow the melting of glaciers.”
2026 Summer Polsky Research Fellowship - Research Assistant with Dr. Peter Irvine, Research Assistant Professor, Department of Geophysical Sciences
“As the global community struggles to limit global warming, interest is growing in interventions to lower global temperatures. SAI, a method of stabilizing temperatures by releasing reflective particles into the upper atmosphere, appears to offer a practical means of doing so. SAI would offer some limited control over climate outcomes, with the total amount of cooling a choice, as well as the relative cooling of high and low latitudes. To understand whether SAI should be pursued will require a rigorous risk-risk analysis of the trade-offs between the novel environmental risks of different SAI scenarios and the “baseline risk” of a rapidly warming world.
For this studentship, you will contribute to an ongoing research project to make a comprehensive assessment of SAI’s potential consequences. This core project is focused on making a multi-model comparison of the response to standard scenarios of SAI, while your project will explore how that response differs for alternative SAI scenarios in a single climate model, the community earth system model. Drawing on existing climate model simulations of SAI, you will apply analytical tools in the python programming language to extend the core analysis to these alternative scenarios.
The ultimate goal is to identify for which variables and in which regions SAI could work well and where it could worsen the impacts of climate change. This work will help provide a vital, evidence-based foundation for an informed discussion of SAI as a climate policy option.”

PODCASTS
Ice, ice, maybe: should the Arctic be refrozen? | The Intelligence
“Many scientists are considering the notion of actively cooling the region that is warming fastest. We examine the merits and the risks—both environmental and geopolitical—of messing with the polar climate.”

Solar Geoengineering Lunch Talk: Harvard’s Zhiming Kuang on Cirrus Clouds | The Salata Institute at Harvard University
“Cirrus clouds – thin, wispy, high-altitude clouds made of ice crystals – play a critical role in Earth’s radiation balance, reflecting incoming solar radiation while trapping outgoing longwave radiation. Because of this dual role, changes to cirrus clouds can result in either warming or cooling in nontrivial ways. The microphysical properties of cirrus clouds, such as the number, size, and shape of ice crystals, influence their radiative effects, and are also highly sensitive to environmental conditions like temperature, humidity, and the presence of aerosols. While stratospheric aerosol injection (SAI) aims to cool Earth’s surface by scattering incoming solar radiation, the strategy’s impacts on cirrus microphysics remain poorly understood, potentially leading to unintended consequences. In this seminar, Prof. Zhiming Kuang gives an overview of his ongoing research on aerosol–cirrus interactions, combining high-resolution simulations, aircraft measurements, and machine learning to provide critical insights into the potential climate impacts of cirrus modification from SAI.”
Frontiers Science House | Experts at odds: debating geoengineering | Frontiers
“What should be permissible in the race to limit global warming, and where do we draw the line on geoengineering?
Experts engage in a frank discussion of climate interventions—from carbon dioxide removal to albedo modification—grounded in the latest science. The session probes decision-making under uncertainty, the role of international norms and governance, and the safeguards needed to avoid moral hazard while keeping options on the table.”
Climate Intervention in the Thick Present: Tipping Points, Haraway and Staying with the Trouble | Operaatio Arktis
“With OA’s founding principle of refusing to accept harm, Anni Pokela crystallized our ongoing mission in her speech in Climate Repair Conference in St. John’s College, Cambridge last summer:
”Since we last really evaluated our climate strategies and our approaches, the reality has changed drastically. So our strategies and our approaches have to change with it if we want to respond. And that’s what climate intervention research is about at its best – not just responsibility, but ability to respond.”
This speech was originally given by OA’s strategy specialist Anni Pokela at the Arctic Repair Conference in Cambridge.”
Emergency Geoengineering & the Virtues of Earth Stewardship by Allen Thompson | The Schweitzer Institute
“Geoengineering, especially solar radiation management (SRM), is increasingly discussed as a response to climate change. This paper argues that, while humans have a moral obligation to serve as planetary managers and can do so without hubris, virtuous Earth stewardship cannot include developing or deploying SRM. In response to the argument that SRM could be justified as a “lesser evil” in a climate emergency, it is argued that SRM could yield genuine moral dilemmas and thus is inconsistent with virtuous planetary stewardship.”
HCI Teaser Film | Healthy Climate Initiative | Healthy Climate Initiative
“A changing climate threatens our coasts, forests, and future—but there is hope. The Healthy Climate Initiative: Regenerating Our Future is a short film that tells the story of scientists, communities, and young leaders working together to cool the planet, restore ecosystems, and inspire collective action. From reforestation in rural villages to workshops at leading universities, HCI is building a movement for a safe and thriving future. Join us in regenerating our planet.”
Greg Slater Update on a Proposal for a First Antarctic SAI Test | Healthy Planet Action Coalition
“Greg Slater will be presenting an “Update On a Proposal For the ‘First Antarctic SAI Test’ (FAST)”. He will be discussing the need to have the first tests of SAI immediately (as in, 10 years ago, or tomorrow at the latest). He will make the case for immediate tests and also present his own set of test proposals.”

Next Nature: Engineering the Biosphere | Roots of Progress Institute
“Climate change is altering the conditions that wild ecosystems - forests, oceans, reefs, and more - are adapted to. Even in a best case climate scenario, conditions are changing faster than evolution can keep up. To keep a vibrant “wild” biosphere, humanity’s only choice is to intervene to accelerate the adaptation and evolution of these ecosystems. This talk covers both the why and the how of engineering the biosphere for a new climate reality, starting with the most critically endangered ecosystem: coral reefs.”

“There are 10 things we must do for the 22nd century to be way better than the 21st. What, why, and how.”
How Do We Get SAI Right?: Risks, Research, and the Route Forward | Roots of Progress Institute
“Stratospheric aerosol injection (SAI) could, in theory, cool the planet within years, buying time to cut emissions and remove CO₂. The big question isn’t whether we could do it — it’s whether we should. And if so, how to do it in ways that minimize risks and protect people and ecosystems. This is why bans on research are shortsighted: it’s imperative that we understand the global impacts to make more informed decisions. We need to be clear on what we know — and what we don’t — and generate the data we need, fast, to guide the decisions we can’t avoid. That’s the responsible path: reducing risks and protecting people and ecosystems—without gambling the planet.”
Risks of Termination Shock with Francisco Estrada | Climate Chat
“In this Climate Chat episode, we interview climate scientist Francisco Estrada about his recent paper assessing the risks of “Termination Shock” following the implementation of Solar Radiation Management (SRM, a.k.a., solar-geoengineering). Termination Shock is a rapid, severe warming spike that would occur if SRM were suddenly stopped, because accumulated greenhouse gases would heat the planet all at once instead of being masked.”
