I think the inflation would be a consequence of that fact that (except for some things), in so far as the efficient market hypothesis applies, we would be operating optimally now except for global warming and ocean acidification; applying the tax pulls us away from that optimum, the economy will then not be as efficient (ignoring externalities); but we should want to do this because the economy is now more efficient when including the externalities.
