A Nobel prize-winning scientist threw out the idea to catch the attention of policy makers and now it's being taken seriously. His idea is to counteract the global warming effect of atmospheric carbon dioxide by seeding the stratosphere with sulphur dioxide to reflect the sun's heat before it reaches the lower atmosphere.
Yup, more pollution will save the planet. Go geo-engineering!
It is not very similar but I'm somehow reminded of the time that the Australians tried to deal with a beetle infestation by introducing the cane toad. That worked out great. Human beings should not fuck with systems that they don't fully understand.
