Times Online reports that Bill Gates is funding research to develop artificial clouds that beat greenhouse gases and protect the planet from global warming. The Microsoft billionaire has provided grants to a San Francisco-based research company, Silver Lining, to create machines that can convert seawater into microscopic particles and spray them upwards to seed the clouds which would reflect the Sun’s rays away from Earth.
Times Online adds:
Silver Lining will develop machines to convert seawater into microscopic particles capable of being blown up to the cloud level of 1,000 meters. This would whiten clouds by increasing the number of nuclei. The trial would involve ten ships and 10,000sq km (3,800sq miles) of ocean. Armand Neukermanns, who is leading the research, said that whitening clouds was “the most benign form of engineering” because, while it might alter rainfall, the effects would cease soon after the machines were switched off.
However, this sun-shielding technology has run into controversy, with some experts believing that the experiment, because of its potential global consequences, needs international regulations. But the scientists involved in the research believe that, with the Climate Summit in Copenhagen failing to secure any international agreement on cutting greenhouse gases, they need to urgently develop technology to protect the world from global warming.
