Former GOP gubernatorial nominee and state Sen. Doug Mastriano (R-Franklin) has introduced legislation seeking to ban conceptual geoengineering techniques he falsely links to the “chemtrail” conspiracy theory.

There have been only a few SRM field experiments to date, and some have been cancelled due to public pressure. In this episode, we explore what SRM field experiments have taken place, how they’ve informed scientific knowledge of SRM, talk with some of the scientists leading those experiments, and discuss how outdoor field experiments of SRM should or could be governed.

Over the past two decades, Global North actors have dominated the field of solar radiation modification. It is time for African leaders to develop a nuanced understanding of these early-stage technologies to shape their development and governance, while also ensuring that they do not derail effective climate action.

Depending on whom you ask, it’s potentially highly dangerous, highly promising or highly uncertain. There aren’t any real guidelines. But, with the future of emissions restrictions also highly uncertain, some researchers say solar geoengineering needs to be on the table.

Dr. Shuchi Talati recently spoke with One Earth about the implications of uncertainty for the governance of solar geoengineering.

Stardust, an Israeli-U.S. startup, intends to patent its unique technology for temporarily cooling the planet.

In this episode, Maha Husain speaks with Hassaan Sipra, who shares insights into the science, ethics, and governance of SRM and its implications for global climate policy.

The Energy and Resources Institute (TERI) in collaboration with the Alliance for Just Deliberation on Solar Geoengineering (DSG), and the School of Global Policy and Strategy at the University of California and Scripps Institute of Oceanography organized a workshop focusing on SRM Geoengineering Scenarios.

AGU TV is joined by Clara Botto, a passionate advocate for ethical climate intervention and a member of AGU’s Early Career Advisory Board. With her dedication to science communication and youth engagement, Clara is helping shape policies that prioritize innovation, inclusion, and impactful solutions for our planet.

COMSATS University Islamabad (CUI), in collaboration with The Alliance for Just Deliberation on Solar Geoengineering (DSG), a US-based non-profit organization, successfully hosted a pivotal stakeholder engagement meeting to discuss the development and implications of a prototype Solar Radiation Modification (SRM) Impacts Dashboard for Malaria in South Asia at the district level.

European Commission scientists call for regulating unproven and risky solar geoengineering. The U.S. president-elect could scuttle any U.N. negotiations.

Whitney Peterson highlights the critical role of transparency and unbiased communication in addressing the ethical challenges and uncertainties surrounding sunlight reflection methods (SRM), showing how building public trust requires inclusive dialogue for equitable, informed decision-making, especially for climate-vulnerable communities.

The urgency to address climate change has spurred interest in climate engineering, raising ethical questions. AGU launched Ethical Framework Principles for Climate Intervention Research, developed with input from diverse voices. It guides equitable, responsible dialogue for various stakeholders. Alia Hassan joins panelists to explore challenges, opportunities, innovations, and ethical guidance in climate intervention.

Some believe there is more research needed into geoengineering, while others are strongly opposed.

Today’s youth are tomorrow’s leaders, inheriting a complex climate and SRM challenges. Engaging them now in SRM research is essential for intergenerational justice, preparing them to make informed, ethical decisions about SRM if needed

During COP29, 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.

Can solar geoengineering be a viable tool to combat climate impacts while ensuring justice and inclusion? This paper delves into the complexities of governance of solar geoengineering, the dynamics between the Global North and South and the role of international bodies in shaping ethical governance.

Clara Botto speaks with Operaatio Arktis about fears and concerns regarding SRM research and its policies. Who needs to be discussing these things on the decision making tables? Are we there yet?

This article profiles David Keith and the controversial field of solar geoengineering, tracing his decades-long advocacy for research on stratospheric interventions to cool the planet, while exploring the scientific, ethical, and political debates the technology has sparked.
