> one day or a decade For one thing, a day and a decade are pretty different. But more important, while a decade is really short on geological timescales, and probably isn't long enough to see natural/geo driven or many astronomically-driven changes... a decade is long enough for humans to get a real idea of trends in human-driven changes, or crossing of certain boundary conditions for long-horizon changes. Is that a double standard, or is that a more finely articulated view?
