Scientists back radical ‘geoengineering’ projects to stop climate change

By Steve Connor, Science Editor

It would be 100 times cheaper to shield the Earth from sunlight with a man-made “sun block” than to cut emissions of greenhouse gases. This is one of the reasons why the world needs an international project to investigate ways of safely manipulating the global climate in addition to cutting greenhouse gases, scientists have said.

Simulating a volcanic eruption by putting man-made aerosol particles into the atmosphere to reflect the Sun’s heat would rapidly lower global temperatures and could provide a vital respite from global warming until cuts in carbon dioxide emissions begin to have the desired effect, they added.
