In a sympathetic biochemical photo-reactive process, the Biosphere has altered the litho-sphere into the pedosphere, the cryo-sphere, the hydrosphere and the atmosphere*

The Loess Plateau in China’s Northwest is home to more than 50 million people. Centuries of overuse led to one of the highest erosion rates in the world and widespread poverty. Two projects (results) set out to restore the Loess Plateau. [more inside]

Air-capture startups

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.

Earth doesn't have an energy problem; the Earth has an energy carrier problem

Alain Goeppert, G. K. Surya Prakash, chemistry Nobel Laureate George A. Olah and colleagues have co-authored a paper (doi: 10.1021/ja2100005) in the Journal of the American Chemical Society describing a novel, cheap material that scrubs CO2 from ambient air, even at the very low concentrations of the atmosphere. The material is easily manufactured, and carbon captured is readily removed from the polymer, allowing recycling of the polymer and sequestration of the carbon. The researchers, co-authors of Beyond Oil and Gas: The Methanol Economy regard this as more than simply a technique for decreasing the carbon emissions of industrial processes and fossil-fuel burning machines, but as possibly an energy-carrier, by using the "catalytic hydrogenation of CO2 with H2 where the hydrogen has been obtained from water electrolysis (wiki).
