There is not one solution for Global Warming and CO2 emissions. No silver bullet, just as in software. This is one more tool, which needs to be used when appropriate. But we also need better legislation, technological improvements, and changes in consumption behavior, locally and worldwide. If we look at each of those things and do the math, the answer will be "it's not enough" or "it's too expensive". We mustn't let that be a showstopper. Of course some solutions are really not viable at all and should be ignored in favor of others, but every solution that helps enough (for some definition of enough) needs to be pursued.
