A group of scientists from Scotland have suggested a unique approach to fighting global warming here on earth. The scientists believe that the answer to global warming on Earth is a giant dust cloud blasted from an asteroid to act as a sunshade for Earth. According to the scientists, a project that reduced the amount of solar radiation the Earth receives by only 1.7% could offset the effects of the global increase in temperature of 3.6°F.
One of the researchers, named Russell Bewick from the University of Strathclyde in Scotland, says that a 1.7% reduction is very small would hardly be noticeable on earth. There are alternatives to using a giant cloud of dust blasted from an asteroid to shield the Earth. Another proposal would place giant mirrors in space, but this plan would be very expensive and require construction in outer space.
