Spreading Sulfate Particles into the Upper Atmosphere to Reduce Global Warming Poses threat for Tropics

Global-WarmingIt has been revealed by a study that the weather system in the tropics could be destroyed by the implementation of an idea by the father of the H-bomb to slow global warming by sowing the stratosphere with light-reflecting particles.

Northern Europe and parts of Asia are likely to be benefitted with the scheme, but rainfall around the equator will see disruptions. This increases the risk of drying up tropical forests in South America and worsening droughts in Africa and Southeast Asia.

Andrew Charlton-Perez, a meteorologist at Britain's University of Reading, said that there are huge risks associated with this kind of geo-engineering. US nuclear physicist Edward Teller and other scientists gave suggestions in 1997 about spreading sulfate particles into the upper atmosphere in order to reflect some sunlight back into space to reduce the Earth-warming greenhouse effect from fossil fuels.

It was revealed in a paper by the British scientists that warming could be reversed, but it would take a staggering volume of particles, called aerosols. Findings were published in the journal Environmental Research Letters.

"To reduce global temperatures enough to counter effects of global warming would require a massive injection of aerosol", said Angus Ferraro at the University of Exeter, south-western England.
