    Good lucky Mr. Turtle…Run as fast as you can….

    There will be a polar vortex every day until the Earth stops spinning or otherwise has no atmospheric temperature differential in conjunction with the presence of liquid water.
    If it just stopped spinning but still had atmosphere and water, then it would have a dark side on which all the ice would build up, which would cause it to spin due to tidal forces, though maybe more of a pendulum effect would be observed.
    Now I’d really like to stop it spinning just to see.

    Although it is possible, I don’t think the earth has ever stopped spinning. However, there is some evidence the earth does wobble a bit on its axis. It is this wobble that influences a variety of changes to the earth’s climate.

    I’ll bet he gets there before the Hare…

    what’s a polar vortex????

    Its the reason we in Minnesota had one of the worst winters in history and the rest of the world was much warmer than usual.

    Except that it can’t have been. While that is a common idea of some of the geologists, the astrophysicists tell us that would exceed the Roche Limit. It’s already so close that it is tidally-locked. Can’t get much closer before the tides would break it up.

    @Nabuquduriuzhur

    Tidally locked — correct. Close to Roche limit — incorrect. Check the formulas and results at http://en.wikipedia.org/wiki/Roche_limit.
    .
    If the moon is assumed to be completely rigid, the limit is about 9400 km, or less than 6000 miles. If assumed to be completely fluid, the limit is about twice that.
    .
    A mean orbital distance of 240,000 miles with a maximum Roche limit of 11,000 means your statement of “Can’t get much closer before the tides would break it up” is exactly backwards. It CAN get much, MUCH closer before a tidal breakup.
    .
    It’s similar to your comment on http://www.gocomics.com/forbetterorforworse/2014/08/07. Exactly backward.
    .
    BTW — since when do you give astrophysicists ANY credence whatsover? They’re the blokes who believe in the big bang, and that the universe is over 14 billion years old. Not created magically 6,000 years ago. Or are you just selective and cherry-pick what science to believe in?

    At least he’s going in the right direction.

    “Why did they put the South so far south?”

    @X X

    They had to, because if it was closer to north, it wouldn’t be south…then there would not be very much north, so you couldn’t tell the difference from north and south…so that is why they put the south so far down, get it ?

    As distance increases, tidal effect decreases.
    This decreases angular momentum transfer rate and may eventually drop enough that it would take infinitely long to eject the moon.

    The weather guys needed to call the Jetstream something else – so they called the cold air (that brought all the rain, wind, snow, snow, and did I mention snow? to the USA and parts of Canada) a Polar Vortex. It didn’t spin. It didn’t suck things in. It did bury stuff under a lot of snow. But it wasn’t some new weather phemon. Just a different name for the same thing that had a much bigger bite than usual.

    Evidently, you missed. It was a Mel Blanc classic.
