Overall, I have yet to see anyone rebut the simple calculations of Vaclav Smil, the resource and risk polymath at the University of Manitoba, who has shown how capturing and processing just a small percentage of today's CO2 from coal combustion would require as much pipeline and other infrastructure as is now used globally to get oil — a costly commodity — out of the ground.

The comment, made during a Jan. 17 interview with the editorial board of The San Francisco Chronicle, essentially explains how the kind of cap and trade mechanism sought by both Mr. Obama and Senator John McCain (the latter at least in his platform, if not on the stump) would make coal combustion ever more costly (unless the world finally gets serious about investing in large - scale testing and deployment of systems for capturing and burying carbon dioxide).

He explained that an article I wrote in 2002 about fires, both natural and human caused, smoldering in coal seams around the world, inspired him, while he was completing a doctorate at the University of California, Berkeley, to switch from studying risks posed by smoldering combustion in spacecraft to those back on Earth.

And for those of you who want to insist that aerosols produced by the uncontrolled burning of coal neutralized the effects of AGW from 1940 to 1979, please explain how the same argument could not be made for the effects of coal - induced aerosols during this earlier period, when no constraints on the polluting effects of coal combustion were present at all.

At present, an estimated 2.8 million people die prematurely each year because of the smoky environments caused by burning solid biomass in inefficient stoves or from combustion of kerosene or coal for cooking.
