Could geoengineering make climate change worse?

Climate News Network: Geoengineering which sometimes seems to be the despairing climate scientists Plan B simply wont work. It wont offer a quick fix to the planets burden of global warming, and it will be difficult to convince anybody that it could work at all. Geoengineering is any deliberate, large-scale intervention in the workings of the climate machine that might offer a way of containing global warming. The accent is on the word deliberate. Humans are already engineering the climate just by continuously...

Geoengineering Doesnt Provide Magic Bullet Global Warming

Bloomberg: Geoengineering, which includes spraying sea salt or sulphate aerosols into the atmosphere to reflect sunlight, wont provide a magic bullet to combat climate change, a University of Oxford study shows. Its too soon to judge the costs and benefits of these concepts, Steve Rayner, the James Martin Professor of Science and Civilization at Oxford, said today in a statement issued jointly with the universities of Leeds and Bristol. The cost estimates for major projects are unrealistic, he said,...

Geo-engineering: Climate fixes 'could harm billions'

BBC: Schemes to tackle climate change could prove disastrous for billions of people, but might be required for the good of the planet, scientists say. That is the conclusion of a new set of studies into what's become known as geo-engineering. This is the so far unproven science of intervening in the climate to bring down temperatures. These projects work by, for example, shading the Earth from the Sun or soaking up carbon dioxide. Ideas include aircraft spraying out sulphur particles at high...

Will geoengineering make people give up cutting their carbon footprint?

Guardian: If you thought there was a machine that could magically remove carbon dioxide from the atmosphere and bury it underground, would you be less likely to worry about reducing your own carbon footprint? The question is not entirely hypothetical. Geoengineering is the catch-all term for a suite of technologies that could one day be used to alter the Earths climate and combat global warming. Most of them are unlikely to ever see the light of day: they are considered too risky, too unpredictable, or...
