Summary of the Article
A new, “out-of-this-world” suggestion by Scotland scientists could help fight global warming. Russell Bewick, a space scientist at the University of Strathclyde (Scotland), suggests using an asteroid in space to create a dust cloud to act as a sunshade for the entire planet. This type of project is known as geoengineering. The idea of using dust clouds in space as a sunshade is not new, but the dust clouds had the risk of dispersing over time by the Sun’s radiation and gravity, as well as gravity of other planetary bodies. In order to solve this problem, Bewick suggests using an asteroid because the asteroid could create a dust cloud and gravitationally anchor the dust cloud to help cool down the Earth. Bewick said that he would never suggest geoengineering over reducing emissions, but it could buy time in order for slower-acting measures such as carbon capture to take effect.
