IPCC plans sending aerosol "mirrors" to space to tackle climate change: Report

June 16, 2011 - London

The Intergovernmental Panel on Climate Change is considering sending reflective aerosols into space under a series of radical "geo-engineering" measures being considered by the UN climate science body to tackle climate change, it has emerged.

The IPCC papers leaked ahead of a key meeting in Peru next week, outline the series of techniques, which scientists hope would manipulate the world's climate to reduce carbon emissions.

The ideas proposed by a group of 60 leading scientists from around the world include producing "lighter coloured" crops to reflect sunlight, blasting aerosol "mirrors" into the stratosphere and suppressing cirrus clouds, The Telegraph reports.

Other suggestions include spraying sea water into clouds as another reflection mechanism, depositing massive quantities of iron filings into the oceans, painting streets and roofs white and adding lime to oceans, the paper added.

According to the paper, experts suggested that the documents showed how the UN and other developed countries are "despairing" about reaching agreement by consensus at the global climate change talks.

Many of the scientists also accept there are major uncertainties surrounding the technologies.ritain has backed a series of research projects with millions of pounds, including one being operated by Bristol University to develop a "hose" held up by balloons, in which sulphates can be sent into the stratosphere.

The disclosures comes as scientists warn that coral reefs around the world could be teetering on the brink of extinction by the end of the century as the oceans become more acidic.
