      folks can well slam how this is written but at the same
      time pretty much know what the author is "trying" to
      convey. Let's put it this way--at age 10 I knew from my
      <br>mother planting peas in the family garden that nitrogen
      was in the air but not in the soil, and somehow some
      plants could do it for you and fertilize your garden.
      <br><br>But what is NOT well known is the very complex
      symbiotic relations between microbes, nor does the author
      touch on the MOST important one, as readers who
      understand the Methane Mike know, regarding the Methanogens
      and <br>their ability to alter ocean conductivity and
      hence alter climate via cirrus clouds. As the debate
      swings toward biology and away from hard physical
      science, I hear a collective gasp from the physical
      scientists who have dominated the climate debate. Well, let
      me give you all a clue--either broaden your horizons
      or you will be left behind, and sadly for you, that
      includes listening to those who have a much simpler
      understanding of what it means to, say, break down CO2.

        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
