Hi All However rather than measuring the mass of cooling material it should be possible to use satellite observations to measure the change in sea surface temperatures in hurricane-breeding ocean regions and pay according to how close they get to values set by the Governments of surrounding countries. Cooling would begin at the end of a hurricane season and the trajectory of temperature change observed to the following year. Stephen

Diamond, Kelly Wanser & Olivier Boucher Climatic Change volume 176, Article number: 96 (2023) 04 July 2023 Abstract As the world struggles to limit warming to 1.5 or 2 °C below pre-industrial temperatures, research into solar climate interventions that could temporarily offset some amount of greenhouse gas-driven global warming by reflecting more sunlight back out to space has gained prominence. These solar climate intervention techniques would aim to cool the Earth by injecting aerosols (tiny liquid or solid particles suspended in the atmosphere) into the upper atmosphere or into low-altitude marine clouds. In a new development, “cooling credits” are now being marketed that claim to offset a certain amount of greenhouse gas warming with aerosol-based cooling. The science of solar climate intervention is currently too uncertain and the quantification of effects insufficient for any such claims to be credible in the near term. More fundamentally, however, the environmental impacts of greenhouse gases and aerosols are too different for such credits to be an appropriate instrument for reducing climate risk even if scientific uncertainties were narrowed and robust monitoring systems put in place. While some form of commercial mechanism for solar climate intervention implementation, in the event it is used, is likely, “cooling credits” are unlikely to be a viable climate solution, either now or in the future.
