Why is aircraft CO2 majick?

A post from Eli about offsetting CO2 emissions from flights raises once again an issue in my mind, which I don’t think I’ve whined about here (do remind me if I have): why is aircraft CO2 special, and requires offsetting, whereas heating your house, driving to work, and all the other things you do to…

That was my starting point, anyway. And I’ll aim to get back to it soonish. But I got sidetracked by the emission theory of vision, an idea so stupid that only a greek philosopher could possibly have thought it up, much less believed it.
