    This is greenwashing. Global aviation uses almost 100 billion gallons of fuel per year. If we even began to address a fraction of that with magic new fuels (which won’t happen) it would require incredible amounts of growing, and if we had that sort of amount of agricultural capacity available on this planet, capable of producing crops at a price the aviation industry is prepared to pay, we wouldn’t have any hunger on the world.

    Don’t fall for this. There isn’t such a thing as green aviation. I’m not saying there should be no flying, but we can’t carry on as we are and magic away the consequences. In particular, don’t fall for the snake oil salesmen trying to distract you with appealing non-solutions








  • A really large number of them are references - possibly dated references - to other things. Sometimes cultural phenomena (the movie Ishtar, which was before my time and I’m really old) but often scientific or other phenomena. In one of his books he mentioned a biology teacher who pinned a load of his comics to the wall and, week by week, the students would go “Ah, now I get that one” as they learned something about chimpanzee communication, eye spots, or whatever.

    Of course, some are just whimsy. And others are warning us about those sneaky sneaky cows…
