      Climate change: The Indonesian valve

      The behaviour of the North Atlantic is often invoked to explain the
      effects of climate change. But for certain episodes, including
      perhaps a period in human evolution, events elsewhere may have had a
      greater influence.

      The climate of East Africa became drier between about 5 million and
      2.5 million years ago, and that may have been the catalyst that
      forced our ancestors to adapt to a savannah environment as the
      forests dwindled1, 2. At about the same time, the Earth entered a
      climate mode dominated by the waxing and waning of large continental
      ice sheets. The coincidental timing of global cooling, African
      aridity and human evolution invites speculation about a common link3.
      For that, we must look to the oceans — in redistributing heat and
      influencing greenhouse-gas concentrations globally, they are the main
      component in determining climate change. Marine records tell us that
      the transition to large-scale glacial cycles took at least a million
      years; and plate-tectonic motions that opened or closed ocean
      gateways are thought to have triggered these events4.

      Comment:

      This is similar to the last article with the same problems. Let me
      just add this about the closure of the passage between the tropical
      Atlantic and Pacific as the Americas joined. This would have profound
      EMF consequences even independant of salinity changes--which must
      have occurred as well.

      Hurricane Lili and Kenna provides an excellent examples of what I am
      talking about. This was a cat 4 to 5 storm that blew up in an earth
      directed CME in the biologically active GOM. It was a beautiful storm
      as far as EMFs are concerned. It was almost perfectly circular and
      had at one point much of the eastern and western edges of the GOM
      fair weather--so it was self contained from an EMF standpoint, at
      least in terms of its circuitry from the oceans were concerned. It
      had 150 mph winds inducting from the northern aspects, drawing in
      cooler air and causing a strong right turn to push surface oceans
      strongly from EAST to WEST. From the south the EMF of the SOI
      reversal from positive to negative was on--and induction process in
      the Pacific. Doran waves brought rain all the way to us in Redding,
      and the GOC continued as a fair weather source of positive voltages
      to ground. It was an awesome electrical display.

      But then the sun went down on the storm. You could actually see real
      time after sunset that there were strikes from the eye. And we are
      talking about a very SMALL eye--less then 10 miles across. This was a
      pinhole. Almost immediately cirrus covered the eye and the storm
      weakened thermodynamically and it landfell as a weak 3. If this same
      storm landfell as a 5, it would have leveled everything in its path
      like a nuke bomb.

      Kenna, OTOH, landfell as the strongest cane to hit that Mexican coast
      in like 35 years. The sun went down on Kenna but it didn't make a bit
      of difference to its EMF--which again I monitored using fractal data--
      strikes, and in particular the severe weather over Texas but also the
      GOC and GOM. Kenna was also a SOI reveral, high CME/solar wind storm.
      BUT, when the sun went down on Mexico, the sun was still providing a
      solar wind to the tropical Pacific, which was connected electrically
      to Kenna to the night side of the earth.

      Likewise, if the main oceans of the Atlantic and Pacific were
      connected electrically, storms would not lose their EMF stability at
      sun set. They could ride further north, especially up the Gulf
      Stream. The Cape Verde waves--the ITCZ, would light up electrically--
      and Africa would get more rain. More rain, more sedimentation, more
      detritus, more EMF enhancing near shore biological activity--wetter
      climate.
