'Refreezing Arctic' can help stop global warming, say scientists
Scientists have offered a new low cost solution to global warming- refreeze the Arctic.
Two recently published studies explored the possibility that a technological solution could be found to the problem of global warming melting the ice caps on the North Pole.
The scientist who is lead author on both claims that 'any significant nation' could find the resources to carry out the operation.
According to the Daily Mail, the amount of ice in the Arctic Ocean shrank to an all time low in September, with the total area covered now half what it was in the Eighties.
David Keith, professor of applied physics at Harvard University, is lead author on papers published in Nature Climate Change and Environmental Research Letters, which speculate as to how we could restore the polar ice, the paper said.
"The really hard questions here aren't mostly technical. They're questions about what kind of planet we want and who we are," he told Canadian newspaper The Windsor Star.
Professor Keith used climate models to suggest that injecting reflective particles into the atmosphere could reduce the amount of sunlight reaching the Earth, engineering a regional effect that could bring ice back to the Arctic.
According to the report, his paper claimed that by reducing the penetration of sunlight by just 0.5 per cent it could be possible to restore the sea-ice around the North Pole back to pre-industrial era levels.
His second paper suggested the whole operation could be accomplished with just a few modified Gulfstream jets, costing somewhere in the region of 8 billion dollars a year, the report said.
