Experiment Earth: Responsible Innovation in Geoengineering by Jack Stilgoe

摘要

In 1991, the volcanic eruption of Mount Pinatubo in the Philippines lofted 17 megatons tons of sulfate aerosols into the stratosphere, cooling the Earth by about 0.5 °C for the next two years. This cooling temporarily offset most of the warming caused by all the greenhouse gases humans had accumulated in the atmosphere since the start of the industrial revolution.
