Climate engineering is an emergency measure, says Nobel laureate
Injecting sulphur into the atmosphere to slow down global warming is worth serious consideration, but should only be used as an emergency measure and does not justify inadequate climate policies, according to new research by Nobel laureate Paul Crutzen.
“Given the grossly disappointing international political response to greenhouse gas emissions” warns Crutzen, geo-engineering may be called upon to reverse the effects of climate change and therefore “should not be tabooed."Sulphate particles, which are released during the combustion of fossil fuels and volcanic explosions, help to cool the planet by reflecting solar radiation back into space. According to Crutzen’s research further cooling could be engineered by sending balloons, laden with sulphate particles into the stratosphere, and using artillery guns to release it.
