The reason the British scientists gave for pulling back was that more time was needed for consultation. In retrospect, it seems bizarre that they had only talked to a few members of the public. It was only when 60 global groups wrote to the UK government and the resarch groups behind the project requesting cancellation that they paid any attention to critics.
Over the Atlantic, though, the geoengineers are more gung-ho. Just days after the British got cold feet, the Washington-based thinktank theBipartisan Policy Center (BPC) published a major report calling for theUnited States and other likeminded countries to move towards large-scale climate change experimentation. Trying to rebrand geoengineeringas "climate remediation", the BPC report is full of precautionary rhetoric, but its bottom line is that there should be presidential leadership for the nascent technologies, a "coalition of willing" countries to experiment together, large-scale testing and big government funding.
Their specially convened taskforce is, in fact, the cream of the emerging science and military-led geoengineering lobby with a few neutrals chucked in to give it an air of political sobriety. It includes former ambassadors, an assistant secretary of state, academics, and a chief US climate negotiator.
Notable among the group is David Whelan, a man who spent years in the US defence department working on the stealth bomber and nuclear weapons and who now leads a group of people as Boeing's chief scientist working on "ways to find new solutions to world's most challenging problems".
There are signs of cross US-UK pollination – one member of the taskforce is John Shepherd, who recently wrote for the Guardian: "I've concluded that geoengineering research – and I emphasise the term research – is, sadly, necessary." But he cautioned: "what we really need is more and better information. The only way to get that information is through appropriate research."
It also includes several of geoengineering's most powerful academic cheerleaders. Atmosphere scientist Ken Caldeira, from Stanford University, used to work at the National laboratory at Livermore with the people who developed the ill-fated "star wars" weapons. Together withDavid Keith, a researcher at the University of Calgary in Canada, who is also on the BPC panel, Caldeira manages billionaire Bill Gates's geoengineering research budget. Both scientists have patents pending on geoengineering processes and both were members of of the UK Royal Society's working group on geoengineering which in 2009 recommended more research. Meanwhile, Keith has a company developing a machine to suck CO2 out of the year and Caldeira has patented ideas to stop hurricanes forming.
In sum, this coalition of US expertise is a group of people which smell vast potential future profits for their institutions and companies in geo-engineering.
Watch out. This could be the start of the next climate wars.
