- Using Metadata to find Paul Revere
From the all-too-rare genre of mathematical-political satire: Using Metadata to find Paul Revere. Highlighting for the uninitiated just how much actual information is really contained in even a wee sliver of the so-called metadata we smear all over the digital universe in our wake. Applied to the Founding Fathers. - Refining Steel Without GHG Emissions
Refining metal ores is one of those things that's really, really hard to do without emitting a huge amount of greenhouse gasses. The energy sources behind our material economies are not as easily substitutable with renewables, because what they often require is extreme heat, and sometimes the carbon itself (in the case of steelmaking and concrete). Researchers at MIT are looking at a way of directly refining molten iron oxide directly into pure iron electrolytically that results in very pure iron, and virtually no emissions, and it might work for other oxide refining processes as well. - Global GHG Sankey Diagram
An interesting Sankey representation of global GHG emissions, from Ecofys, updated with data from... 2010. Yowza. Would be good if we could get much more timely reporting of this stuff. - High Plains Aquifer Dwindles
The fossil waters underlying the Great Plains, left over from the Pleistocene, are giving out. We done sucked 'em dry. Any hydrologist could have told you it was in the works. We'll see the end of fossil ground water pumping in the 21st century, whether we like it or not. - Communicating sustainability: lessons from public health
Some lessons from public health for sustainability and climate campaigners. Our choices are largely not our own -- context and norms are far more powerful forces for behavioral change than abstract attitudes. Most people just stick with the default settings. We need to change the default settings.

NRDC plan to cap GHG emissions from power sector using the Clean Air Act.
The NRDC has a plan that would allow the EPA to regulate GHG emissions from existing power plants, without either capitulating to the power sector, or banning coal outright immediately (which would be politically… uh, difficult). The trick is to … Continue reading
