Commenting on a report published today by the Royal Society, looking into the feasibility and potential dangers of tackling climate change with geoengineering, Friends of the Earth's Head of Climate Change Mike Childs said:

'Geoengineering is no silver bullet - it won't solve climate change. The different options will take time to develop, risks need to be properly researched, and if we use geoengineering at all it must be in addition to making deep cuts in the amount of carbon dioxide we produce in the first place.

'We haven't got time to play Russian roulette with the future of the planet. If we have any hope of avoiding runaway climate change, rich countries must reduce their emissions dramatically and quickly, as well as providing billions of pounds to enable developing countries to grow cleanly.

'Investing in green industries will slash carbon emissions, create hundreds of thousands of jobs, and lead us out of recession towards a clean, stable and prosperous global economy.'
