“Giant engineering schemes to reflect sunlight or suck carbon dioxide from the air could be the only way to save the Earth from runaway global warming, according to a group of leading scientists. But they say that these schemes could have their own catastrophic consequences, such as disrupting rainfall patterns, and should be deployed only as a last resort if attempts to reduce greenhouse gas emissions fail. The Royal Society, a fellowship of 1,400 of the world’s most eminent scientists, published a report yesterday on the feasibility and possible dangers of technologies for cooling down the Earth, known as geoengineering.
