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
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.
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
