Three startup companies led by prominent scientists are working on new technologies to remove carbon dioxide from the atmosphere. These scientists have launched start-up companies and attracted well-to-do investors — most notably Bill Gates — along with venture capital and, most recently, the attention of Wall Street.

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.

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.
