Applying huge doses of solar geoengineering to offset all warming from rising atmospheric C02 levels could worsen the climate problem — particularly rainfall patterns — in certain regions. However, through modeling, a team of researchers in the US (Harvard University, MIT, Princeton University Georgia Institute of Technology) found that if solar geoengineering (SG) is used to cut global temperature increases in half, no IPCC-defined region is made worse off in any of the major climate impact indicators. Climate models suggest that geoengineering could enable surprisingly uniform benefits. The model indicates that SG moderates changes in water availability and extreme precipitation in many places and offsets more than 85 percent of the increase in the intensity of hurricanes. Less than 0.5 percent of the land would see the effects of climate change exacerbated, according to the model…read more. TECHNICAL ARTICLEÂ
