Blast the Atmosphere with Sulphur to Slow Global Warming, Study Suggests

A paper produced by Nobel laureate Paul Crutzen of the Max Planck Institute for Chemistry in Germany and the Scripps Institution of Oceanography, San Diego, suggests that sulphur introduced into the earths atmosphere may slow global warming.

Crutzen observed the effects of volcanic eruptions and fossil fuel use, noticing that both emit sulphate particles which reflect incomming solar radiation back into space, which in turn produces a cooling effect in the earths atmosphere.

It is proposed that sulphur is released in large quantities into the stratosphere, with the effect lasting about 2 years. Such a plan, he says, may be required given the current inadequate political response to greenhouse gas emissions.
