By Alister Doyle; Editing by Simon Robinson and Sara Ledwith30 August 2013 (Reuters) – Last year the Haida, an indigenous group in Canada, set out to increase their salmon stocks and save the planet. Helped by American businessman Russ George, a group of villagers dumped 100 metric tons (110.23 tons) of iron dust from a […]
By Dana Liebelson and Chris Mooney17 July 2013 (Mother Jones) – The Central Intelligence Agency is funding a scientific study that will investigate whether humans could use geoengineering to alter Earth’s environment and stop climate change. The National Academy of Sciences (NAS) will run the 21-month project, which is the first NAS geoengineering study financially […]
By John Abraham 7 July 2013 (The Guardian) – Perhaps I have been naïve, but for many years I have held the view that economists were good decision makers and that part of being a good decision maker was to seek out good information. Well-informed decisions, I thought, allowed people to earn better returns, to […]
By CLIVE HAMILTON26 May 2013 CANBERRA, Australia (The New York Times) – The concentration of carbon dioxide in the earth’s atmosphere recently surpassed 400 parts per million for the first time in three million years. If you are not frightened by this fact, then you are ignoring or denying science. Relentlessly rising greenhouse-gas emissions, and […]
By Ian Sample, science correspondent 31 March 2013 (The Guardian) – Controversial geoengineering projects that may be used to cool the planet must be approved by world governments to reduce the danger of catastrophic accidents, British scientists said. Met Office researchers have called for global oversight of the radical schemes after studies showed they could […]
By Jeff Hecht9 February 2013 (New Scientist) – Geoengineering is being tested – albeit inadvertently – in the north Pacific. Soot from oil-burning ships is dumping about 1000 tonnes of soluble iron per year across 6 million square kilometres of ocean, new research has revealed. Fertilising the world’s oceans with iron has been controversially proposed […]
By Kathryn Doyle28 November 2012 It’s hard to stop a bad idea with enough money behind it—even rogue science on the high seas. Russ George, a wealthy American businessman with a history of big, controversial ideas, launched his latest one this October: dumping 200,000 pounds of iron sulfate into the North Pacific. His aim was […]
By Michael Marshall21 October 2012 If we have to hack the planet, we could at least do it with some finesse. Some of the problems with geoengineering could be fixed by targeting specific regions of the planet, rather than cooling everywhere equally. A rough modelling study published in Nature Climate Change offers a crude blueprint […]
