“Researchers…have carried out the first comprehensive assessment of the relative merits of different geoengineering schemes in terms of the climate cooling potential…Climate geoengineering proposals seek to combat the effects of climate change—in particular to counteract the effects of increased CO2 in the atmosphere. There are two basic approaches proposed: reducing the atmospheric absorption of incoming solar (shortwave) radiation, or removing CO2 from the atmosphere and transferring it to long-lived reservoirs, thereby increasing outgoing longwave radiation….” Full Slice
