Unfortunately, the Vienna Convention is toothless, and its provisions have been ignored. Therefore, rebooting the Vienna Convention to govern SRM research is essential.

Solar radiation modification (SRM), a group of technologies to deliberately reflect sunlight into space to cool the planet, is now being seriously explored as a solution to the climate crisis. In theory, injecting sulphur droplets into the stratosphere, salty water into clouds, or scattering glass over polar ice could slow global warming by changing the Earth’s energy balance. But as these experiments involve risks at a planetary scale, we should proceed with abundant caution, communication and transparency, regulated by globally agreed standards. Instead, we see ethical and legal boundaries being crossed by unregulated experiments.
