Climate Change : Sun to be blocked out by chemical spray

Harvard scientist David Keith and his partner are set to spray the sky with aluminum oxide and other chemicals to experiment with geoengineering: solar radiation management (SRM) as they call it, to block out the sun. They would be among the earliest official geoengineering-related experiments conducted outside of a controlled laboratory or computer model, underscoring the growing sense of urgency among scientists to begin seriously studying the possibility as the threat of climate change mounts. US scientists are set to send aerosol injections 20km up into the earth’s stratosphere in the world’s biggest solar geoengineering programme to date, to study the potential of a future tech-fix for global warming. The $20m (£16m) Harvard University project will launch within weeks and aims to establish whether the technology can safely simulate the atmospheric cooling effects of a volcanic eruption, if a last ditch bid to halt climate change is one day needed. According to some experts who are protesting to the proposal to spray the skies, in 20 years we’ll be living in an aluminum poisoned nightmare where questioning the health of geoengineering the weather, hazing out the sun to combat climate change, will be as taboo as being critical of vaccines.
