Home from work today because the babysitter is off, and came across this on Treehugger, which if you've never seen it is probably the best environmentally-related blog around. Apparently NASA climate scientist James Hansen is proposing a new idea for reducing greenhouse gas emissions by phasing out the burning of coal for power. Instead, he would have current coal-fired power plants burn wood. That, combined with carbon capture and storage technology, and the re-planting of carbon-eating forests, could be enough to seriously reduce the threat of climate change. Of course, the problem that immediately comes to mind is the massive number of trees that would be required. You'd have to set aside massive tracts of what are, in effect, tree farms for electricity production. In any case, I'm always interested in hearing new ideas about stopping climate change, and this one definitely sits outside the box. Thoughts?
