      Dust would be repelled by strong magnetic fields,
      and cold oceans are less conductive than warmer
      oceans.<br><br>This is where an intereresting feedback exists. For
      instance, the magnetic feild was over 2 Gauss 3,000 years
      ago, four times stronger than today. Did that time get
      4 times the cirrus enhancement, perhaps 4 times the
      precipitation? I strongly suspect NOT. However, when these
      storms DID move over oceans, the connectivity between
      convection and electrical fields, and between electrical
      fields and magnetic fields, when put into the context of
      the moving oceans as moving conductors, puts them all
      together. The greater magnetic field was, therefore, a sign
      of what was going on. And this brings me back to the
      fact that our magnetic field has shrunk 10% over the
      past 150 years. As humans emerged from Africa about
      730,000 years ago the earth's magnetic feild reversed.
      Today, if there as a climate shift from a pole
      reversal--there would be no place to run.

        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
