Desperate Scientists May Try Sun Shield
Since the small, practical actions necessary to help prevent global warming have not been taken, scientists are now considering crazy schemes to get the job done.
Mark Townsend writes in The Observer that U.K. climate scientists are proposing to build a massive shield on the edge of space that would deflect the Sun’s rays and stabilize the Earth’s climate. It would be made up of thousands of tons of small metal pieces, ejected into the upper atmosphere. Another sun barrier could be billions of tiny balloons sent into space. These ideas were inspired by the cooling effect from the 1814 volcanic eruptions in Indonesia, which spewed enough matter into the upper atmosphere to cause temperatures to fall by 30% for 3 years.
