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.

"So by this analysis dead-tree magazines have a smaller net carbon footprint than web media. We cut down trees and put them in the ground. From a climate change perspective, this is a good thing" explains Chris Anderson, Wired Magazine's editor-in-chief. While some decry this type of carbon footprint accounting as "cheating", the paper industry has lately been eager to convince the public that they are carbon-neutral.

CARMA, released today, is a map/database that shows the carbon emissions of more than 50,000 power plants and 4,000 power companies in every country on Earth, showing not only the worst but the best. Find out how much CO2 comes from electricity plants in a particular city, county, congressional district, company, town, ZIP code, or an individual plant.

Global warming -- the upside: the entrepreneurs poised to make millions from new ports and shipping lanes in the formerly ice-bound Arctic circle. A fascinating New York Times article on the international land-grab following the news (reported here, discussed here, whitewashed here, et. al.) that the polar ice caps and Siberian permafrost are melting. Goodbye Gulf Stream, hello Club Med Santa-style -- first SUV to the North Pole wins!

Eprida: using biomass to produce hydrogen, reduce the emissions of coal-fired power plants, and suck CO2 out of the atmosphere, all while improving agricultural productivity. A new virtuous cycle (flash)?
