A few days ago, the UK-based Stratospheric Particle Injection for Climate Engineering project, or “SPICE,” was asked to delay its initial step in a project aimed at cooling the Earth’s climate. Essentially, its ultimate aim is to one day mimic the effects of volcanic eruptions through the large-scale spraying of climate-cooling sulphate particles into the stratosphere. The first step is to use water particles sprayed from a balloon, but that will have to wait. (more…)
