Carbon Sequestering Issues

     The linked article only glosses over the details, but it throws out a number of only a 1% release of carbon per 1000 years for any carbon sequestering system to be useful for preventing global warming.  That's not really a shock to me, but I wonder if anybody who thinks they're going to save the world by "sequestering" carbon through biological means has read this.

     It really gets under my skin when people talk about using tree plantations, or even farming as "Carbon Sinks".  What do they think happens to the carbon wrapped up in those trees and crops when the trees get milled and the food gets eaten?

     Trees could at least have some merit as a delaying tactic, once you've churned the atmospheric carbon into wood, it'll take quite a few years for it to be released again - providing the wood isn't just burned.  I don't even want to think about eating produce from crop which is going to be able to "sequester" carbon for any significant period of time though.  I'm picturing something like the worst scone ever.  Extra dense, heavy and dry, that's going to go in one end but never leave.  And it'll last longer than you will.  Yech.
