      Finally, I would point out that it isn't a year
      where there is significant Keeling Whorf methane
      hydrate depressurization. See figure
      1:<br><br><a href=http://www.pnas.org/cgi/content/full/070047197 target=new>http://www.pnas.org/cgi/content/full/070047197</a><br><br>This graphic shows that depressurization is relatively
      low, but it isn't at its lowest point either, which
      would corresponde to the Little Climatic Optimum. If
      you combine high CO2 levels w/ Little Climatic
      Optimum depressurization and dams leveling off (to me CO2
      as a GHG isn't nearly as huge a forcing as cirrus
      activity), that is where you are going to see your greatest
      warming. OTOH, the earth's magnetic field has been reduced
      or morphed about 10% over the past 150 years. This
      correspondes to reduced cirrus activity, such that if it is
      related to warmer oceans and more stabile methane hydrate
      fields, than we can expect further reductions of the
      field in the coming years, and perhaps some modulation
      of the cirrus activity--at a cost of potential
      non-linear change of magnetic fields that could be THE
      event.

        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
