About

Speakers highlighted the need to build capacity in the Global South in
solar geoengineering—an approach to limiting global temperature increases
by reflecting sunlight. Building this expertise would help address the
imbalance of most research and governance occurring in the Global North.

The 2023 Emissions Gap Report
<https://www.unep.org/resources/emissions-gap-report-2023> from the UN
Environment Programme (UNEP) delivered a stark warning: even full
implementation of the Paris Agreement would fall far short of keeping
global temperature rises below 2°C. This alarming gap has brought
alternative options, such as solar radiation modification (SRM), into
sharper focus. SRM aims to limit global temperature increases by reflecting
sunlight back into space, but its inclusion in policy discussions raises
significant risks and uncertainties. This side event sought to promote an
open and inclusive dialogue—particularly within the climate-vulnerable
Global South—on critical governance and research issues surrounding SRM.

In opening remarks, Anita Nzeh, The Degrees Initiative, outlined her
organization's mission to empower the Global South to actively participate
in global discussions on solar geoengineering. She emphasized that The
Degrees Initiative funds 35 research teams across 22 developing countries,
maintaining a neutral stance on whether SRM should ultimately be deployed.
Instead, she said, the focus is on building capacity to study its potential
impacts on these regions.

In an introductory presentation, Andy Parker, Chief Executive Officer, The
Degrees Initiative, explained that SRM gained attention after it was
observed that large volcanic eruptions, resulting in volcanic sulfate
particles reflecting incoming sunlight have cooled the atmosphere. While
the possibility of geoengineering such a cooling process has been
demonstrated and that it would take USD 10-20 billion per year to deploy
it, the question of whether it should be undertaken raises ethical,
economic, and political considerations.

Continuing the presentation, Nana Ama Brown Klutse, University of Ghana and
Vice-Chair of Working Group I (WGI) of the Intergovernmental Panel on
Climate Change (IPCC), then stressed SRM research focuses on computer
modeling rather than deployment of the technology. When applied prudently
and in conjunction with net-zero objectives, it could mitigate risks like
sea-level rise or intense storms, but careless deployment poses serious
dangers, such as taking attention away from mitigation efforts, overcooling
the planet, or disrupting regional weather patterns. Socio-politically, SRM
raises moral hazards, she said, for example, could it undermine CO2
reduction efforts or could it, in fact, galvanize stronger climate action?
Governance and equity concerns loom large, she underscored, particularly
over decision-making between the Global North and South. “Politics,” Parker
then added, is the “single most difficult dimension.” He warned against
unilateral uses of the technology and potential difficulties in finding
consensus over where to “set the world’s thermostat,” asking: Would a world
with SRM be more, or less, governable than a world with climate change?

A Q&A session highlighted the urgency of discussing SRM within the UNFCCC
despite the risk that it could overshadow decarbonization efforts. Speakers
emphasized the need for research to understand its potential impacts,
including lessons from past sulfur reductions, to address trade-offs.

An ensuing panel discussion was moderated by Matthias Honegger,
Perspectives Climate Group and Lead, Co-CREATE project. Hassaan Sipra,
Director of Global Engagement at the Alliance for Just Deliberation on
Solar Geoengineering, emphasized the growing civil society interest in SRM,
driven by the urgent need for governance to prevent siloed and exclusive
decision-making. With climate change hurtling toward a 3°C rise by 2100,
the question becomes whether SRM risks are the lesser evil compared to
unmitigated climate impacts. Ignoring SRM, he said, allows unchecked
actions by non-inclusive entities: for example, rapid advancements,
including recent philanthropic initiatives, are largely funded by Global
North institutions. Sipra stressed the importance of Global South
perspectives in shaping equitable global decisions.

Lisa Graumlich, President, American Geophysical Union (AGU), highlighted
the critical need for an ethical framework to guide SRM research and
decision making. Under AGU’s leadership, she described the Ethical
Framework Principles for Climate Intervention Research
<https://www.agu.org/learn-about-agu/about-agu/ethics/~/link.aspx?_id=e04e8e8cf0a7416c9eedab7389af8ee7&_z=z>,
which was developed to ensure that research aligns with ethical principles
and is inclusive, transparent, and representative. Graumlich emphasized
that SRM must complement, not replace, emission reductions as part of a
comprehensive climate strategy. She outlined five key principles contained
in the Ethical Framework: responsible research; holistic climate justice;
inclusive public participation; transparency; and informed governance
through independent review.

Thelma Krug, Climate Overshoot Commission and former IPCC WGI Vice-Chair,
discussed the inclusion of SRM in successive IPCC assessments, noting
increased references and research over time but no restrictive language.
She emphasized the significant gap between modeling and experimental SRM
research, expressing doubts about current progress. The Climate Overshoot
Commission’s report Reducing the Risks of Climate Overshoot
<https://www.overshootcommission.org/report>, she continued, advocates for
small-scale SRM simulations and stresses the need for Global South
researchers' involvement. Krug highlighted the importance of research
funding agencies supporting quality studies and called for governance
principles to enable responsible research as part of broader climate
strategies, with clear communication to the public and policymakers.

Jason Jabbour, UNEP, outlined the rationale for the One Atmosphere Report
<https://www.unep.org/resources/report/Solar-Radiation-Modification-research-deployment>,
emphasizing the need to enlist a multidisciplinary expert panel to engage
in a comprehensive review of emerging technologies and interventions. The
report, he continued, highlights significant gaps in knowledge,
particularly around socioecological and environmental risks, much of which
remains conceptual. Jabbour raised concerns about the dominance of Global
North modeling, stressing the need for equitable access to knowledge and
inclusive research. He underscored the importance of scientific review to
inform discussions, urging proactive engagement within UNFCCC contexts
rather than avoidance: “It is not the time to bury our heads in the sand,”
he concluded.

The Q&A session emphasized the challenges of creating a stable, long-term
governance framework for SRM, highlighting concerns about unilateral
actions and the dominance of Global North perspectives in research and
decision-making.
