How Scientists Planned to Copy Effects of Volcano Eruption to Fight Global Warming

Researchers are to duplicate the impacts of a gigantic volcanic emission to obstruct the Sun’s beams and combat global warming.

As a feature of a £2.3million ($3million) test mostly subsidized by Microsoft’s Bill Gates, a group from Harvard University will splash modest chalk particles into the environment 12 miles over the Earth to mirror a portion of the Sun’s beams once more into space.

They hope this will have a comparable impact to an emitting fountain of liquid magma discharging sulfur dioxide. In 1991, Mount Pinatubo ejected in the Philippines, discharging 20million huge amounts of sulfur dioxide. That cooled the planet by 0.5C for year and a half.

The goal is to reduce the worst effects of climate change in the hope that this could save coral reefs and polar ice sheets.

The team hopes to launch a steerable balloon over the southwest United States before next July. It will release jets of calcium carbonate: chalk dust. Scientists will measure how this affects the Sun’s light.

Opponents say spraying particles in such a way might damage the ozone layer and disrupt rainfall patterns, which could cause drought in some areas, according to The Times.

And they say such geo-engineering diverts attention from cutting greenhouse gas emissions.

They hope this will have a similar effect to an erupting volcano releasing sulphur dioxide, which has a cooling effect (pictured: Steam rising from Fuego Volcano, Guatemala)
