      agree with the tidal overturning theory, for like
      reasons above. Winds don't move the oceans, oceans move
      the winds. Likewise, tides cycles don't stir the
      oceans stratafication, they do something more -- they
      relatively depressurize methane hydrates. <br><br>Mechanisms
      that put us back to coldness are the Little Ice Age
      cycle, which depends on the orbit of the moon, then in
      turn depressurizes methane hydrates. Also there is the
      Milankovitch, with methane hydrates depressurized by falling
      oceans. Recently as the oceans have been diluted phase
      change temperature of hydrates has increased more than
      the temperature itself of the ocean has, so only
      formation is favored, but this can quickly flip. The best
      example of this is in eddies, such as in the Medeteranean
      or near the
      poles:<br><br><a href=http://puddle.mit.edu/~helen/oodc.html target=new>http://puddle.mit.edu/~helen/oodc.html</a><br><br>There, water is too warm or salty for methane hydrates
      to form.

        On Feb 28th, the Interplanetary Magnetic Field
        swung to a strong south-pointing orientation. That,
        coupled with an elevated solar wind speed and density,
        triggered a G-1 class geomagnetic storm. The result was
        some high latitude aurora. See this link for a
        photgraph of aurora observed over Quebec :
        <a href=http://www.spaceweather.com/aurora/images/01mar02/Moussette2.jpg target=new>http://www.spaceweather.com/aurora/images/01mar02/Moussette2.jpg</a> . As of right now, there are 3 sunspot regions,
        namely 9839, 9842, and 9845, that appear to be capable
        of producing M-class flares. Regions 9839 and 9842
        are close to rotating out of view over the western
        limb of the solar disk. Sunspot region 9845, however,
        is close to the sun's central meridian. A rather
        large coronal hole is also approaching the sun's
        central meridian, and coming into an Earth-pointing
        position. High speed colar wind gusts are likely around the
        first of next week.<br><br>The current solar and
