Private jet travel — the worst of the mortal carbon sins — of course would be banned, at least until we can transition into solar and wind aviation. Al Gore in the middle seat of Row 44, fighting to put his oversized carry-on into the overhead compartment, would be a symbolic act worth far more than all his heated and well-paid rhetoric.
