Roger - I know from your other posts here that you're not an idiot, but
/please/ go and find out some of the facts behind this topic before
posting in a way which makes you look like one. Volcanic CO2 emission
fluctuates over periods of a few years (though not by that much) and so
forms part of an equilibrium system: combustion of fossil fuels (and thus
release of carbon stored over million-year timescales) /isn't/ part of
this equilbrium system, and carbon dioxide levels are now certainly higher
than they have been in (certainly) the last 100000-odd years (almost
certainly in the last few million). All of this is well-established and
well-documented. Please do yourdelf a favour and familiarise yourself with
the issues before making yourself look like the fool you're not again.
Houghton's "Global warming" (Cambridge U. Press) is a good introduction.
