      <br><br><a href=http://www.vision.net.au/~daly/sun-enso/sun-enso.htm target=new>http://www.vision.net.au/~daly/sun-enso/sun-enso.htm</a> <br><br>High flaring increases cirrus over
      southern ocean opposit to Antarctic Circumpolar and gyre
      in South Pacific, specifically South Pacific, Peru,
      South Equitorial and East Austrilian currents can flow
      further south. This allows counter current to flow, that,
      despite electrically pulling down cirrus as moving
      eastward is balanced against upward pull of more charged
      ionosphere from flaring. Hence flaring, a very small portion
      of thermal forcing, becomes much larger forcing via
      its electrical aspects. <br><br>Now, in this context,
      what will higher CO2 and therefore more methanogens
      and methane hydrates do to this aspect? It should
      increase the insulation and therefore the strength of the
      East Austrialin and Brazil currents as well as the
      downward electrical current from the Antarctic
      Circumpolar. Note that largely there is a relative absence of
      rivers in the southern hemisphere, such that higher CO2
      there is going to have less of a methanogen impact, and
      would be more about flaring or volcanic forcings
      compared to the northern hemisphere.

        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
