Geoengineering could have 'catastrophic consequences': Schemes to control climate change could backfire, warn scientists
Geoengineering is the deliberate manipulation of environmental processes
Techniques include reflecting sunlight from space, adding lime to the oceans, and irrigating vast expanses of the deserts to grow trees
Report said geoengineering would be unable to prevent average surface temperatures from rising more than 2°C (3.6°F) by 2100

Schemes to deliberately manipulate the Earth’s climate could prove useless, and at worst harmful, claims a new study. The strategies include reflecting sunlight from space, adding lime to the oceans, and irrigating vast expanses of the North African and Australian deserts to grow trees. Known as geoengineering, ideas such as these have gained popularity with some governments attempting to meet their carbon emission targets while still producing cheap energy.

Controversial plan to artificially cool the planet by firing aerosols into the atmosphere might NOT be as risky as thought, experts claim
Some scientists have proposed using aerosols to reflect radiation and cool Earth
But, a study earlier this year claimed it could backfire by making warming worse
If the technique were abruptly stopped, it would cause warming at faster rate
Scientists now say that this worst-case scenario, while scary, is not very likely

As the world grapples with different strategies to mitigate the warming climate, few have sparked such controversy in recent times as solar geoengineering. The proposed plan would use aerosols, fired into the stratosphere with high-flying aircraft, to cool the planet by blocking radiation from the sun.
In a new paper published to the journal Earth’s Future, a pair of researchers from the Institute for Advanced Sustainability Studies in Potsdam, Germany and the John A Paulson School of Engineering and Applied Sciences at Harvard University explain that the current analyses focus on the worst-case scenario.
