The European Union has been urged to take a proactive stance on advocating for a global agreement that would regulate the use of Solar Radiation Management (SRM) technologies to combat climate change. This marks the first time the EU has received scientific advice on these controversial technologies, which are designed to temporarily reduce the impact of extreme heat by blocking some of the sun’s warming effects.
The Risks of SRM Technologies
SRM technologies include methods such as pumping aerosols into the atmosphere, spraying saltwater into clouds, or using mirrors in orbit to reflect sunlight away from the Earth. While these methods may provide temporary relief from rising temperatures, they do not address the root cause of climate change – greenhouse gas emissions. The deployment of SRM technologies carries significant uncertainties and risks that are poorly understood, according to the EU report. These risks include changing rainfall patterns, impacts on ecosystems, food production security, and potential negative effects on solar energy. Expert Recommendations
The EU scientific advisors have recommended that the EU prioritize reducing greenhouse gas emissions and focus on adapting to climate change impacts as primary solutions to global warming. They have also called for an EU-wide moratorium on the deployment of SRM technologies, citing inconsistencies with Europe’s precautionary principles and the potential harm to humans and the environment. Global Governance and Research
Despite the risks associated with large-scale deployment of SRM technologies, there is currently no international framework governing these activities. The EU advisors have proposed creating clear ethical requirements and guidelines for smaller research projects, with reassessments of scientific evidence every five to 10 years. The EU is encouraged to lead negotiations for a global governance system and push for a non-deployment agreement on SRM technologies in the foreseeable future. Diverse Perspectives on SRM
While some experts argue that outdoor research on SRM technologies is necessary to inform discussions and decision-making, others caution that it could normalize the technology for future deployment. Calls for an international norm shift towards the non-use of SRM technologies have been echoed by experts who warn of the potential risks associated with deploying these technologies on a planetary scale.

In conclusion, the EU faces a critical decision on how to approach the regulation and deployment of SRM technologies. While some advocate for further research to inform policy decisions, others warn of the slippery slope towards normalizing risky technologies. The global conversation on SRM governance is ongoing, with experts urging caution and a focus on reducing greenhouse gas emissions as the primary solution to combat climate change.
