Mitigation of Arctic permafrost carbon loss through stratospheric aerosol geoengineering
Abstract The Arctic is warming far faster than the global average, threatening the release of large amounts of carbon presently stored in frozen permafrost soils. Increasing Earth’s albedo by the injection of sulfate aerosols into the stratosphere has been proposed as a way of offsetting some of the...
