      Scripps Scientists Show For The First Time How
      Much Ocean Whitecaps Impact Global Temperatures
      <br><br><a href=http://www.sciencedaily.com/releases/2001/05/010509083635.htm target=new>http://www.sciencedaily.com/releases/2001/05/010509083635.htm</a><br><br>This white cap theory is awful, because it again
      ignores Gaia and biological systems. Gaia modulates
      climate. I wonder if it is the timescales that has messed
      up our best thinkers. <br>By analogy consider cancer
      in evolutionary timescales. Obviously, over
      extremely long time scales, for instance, we have evolved
      feedbacks that protect our lungs against getting cancer
      from smoke. If there is only 4 or 5 mutation of
      oncogenes, the cell is not going to grow and divide without
      control. But if just one cell has 6 or 7 mutations, and
      smoking cigs is a type of activity that has a probability
      to cause such an event, then the person dies of
      cancer. Now, I would argue that smoking, if left
      unchecked by doctors and younger people died from it and
      therefore didn't pass on their genes, or older people died,
      and passed less wisdom/assets to their community,
      would have a smaller chance of survival, and hence over
      very very long time scales you would evolved maybe the
      ability for 8 or 9 mutations. Along the same lines, there
      are actually some microbes that have the ability to
      have their DNA ripped to shreds by UV light and still
      reproduce, as there is in their biology a self-repairing
      mechanism. <br><br>We know a little about the future but if
      you plant a seed of a tree and provide generally
      conditions of growth you will have a tree on a defined
      timescale. If enough of what is climate is determined
      biologically, then climate itself is determined and not chaos.
      Further, one must distinguish between chaotic stimulus and
      regulated, or modulated response. Again, as an example, one
      cannot tell WHICH cell will have 7 or 8 mutations, or
      what smoke particle will cause the individual
      mutations. Thus, chaos is not out of the picture, but to
      talk about chaos without biology is like talking about
      math without numbers. And the wave theory is just more
      of the same confusion.

        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
