Sucking CO2 out of the air has long been a holy grail for solving global warming; Richard Branson has promised $25m to anyone who succeeds. Of course it's already been done, but the amount of energy required doesn't make it net carbon positive. Now a team in Arizona, led by Klaus Lacknet under the company of Global Research Technologies, says it has made a significant breakthrough that massively reduces the amount of energy required - the "project has reached the stage where it is quite clear we can do it." The planned prototype, which will be finished in two years, will cost $200,000 USD, be smaller than a shipping container and be capable of eliminating around 1 ton of CO2. Even if it works many hurdles remain but it portends a cooler future for air-capture technology.

New maps show US fossil fuel emissions aren't where we thought they were. The Vulcan Project collects more accurate data at a higher resolution than previous studies. Explanatory video. via

The University of Columbias Earth Institute has successfully demonstrated carbon dioxide air capturing. As to what could be done with the carbon dioxide after, the IPCC has some ideas (pdf). Unfortunately they don't state how much energy these machines consume or how expensive (toxic, etc.) their prodction is going to be.

Climate change a 'questionable truth'. Margaret Wente looks beyond the hysteria surrounding the climate change debate. Hysteria her own newspaper has been contributing to.

CO2 'highest for 650,000 years' Current levels of the greenhouse gases carbon dioxide and methane in the atmosphere are higher now than at any time in the past 650,000 years. (Found via Treehugger) Sounds like it's time to buy that lovely oceanfront property in Kansas.
