      Earth 's ancient heat wave gives a taste of things to come


      "IT 'S a nightmare scenario - slowly rising sea temperatures trigger
      the release of massive amounts of methane that dramatically amplify
      the greenhouse effect, causing runaway global warming. Hopefully it
      won 't happen, but if it does it won 't be the first time. This exact
      chain of events was played out 55 million years ago.

      Tremendous amounts of the powerful greenhouse gas methane are stored
      in icy hydrates under the seabed and in permafrost. The total amount
      of carbon in the hydrates is an estimated 10,000 gigatonnes, twice
      that in the reserves of all other fossil fuels combined and more than
      enough to dwarf the 750 gigatonnes of carbon in the atmosphere as
      carbon dioxide.

      If today 's warming continues and deep-sea temperatures cross the
      threshold at which methane hydrates melt, huge amounts of methane
      could be released, triggering drastic global warming. It isn 't known
      how likely this is, but researchers have shown that something similar
      happened at the end of the Palaeocene epoch. Fifty-five million years
      ago, a gradual warming of the oceans preceded a dramatic shift in
      carbon isotope ratios and a steep jump in water temperatures -
      precisely the pattern expected if gradual warming melted the hydrate
      reserves. Looking at what happened in the Palaeocene helps to answer
      two crucial questions : how much of the methane can be released at
      once, and how that would affect climate."

      The taste of what is to come is on billion year timescales . . . a
      red sun and boiled oceans. This gets back to Carl Sagan's mystery and
      the ever lumenous sun--and how the biosphere leaves all the clues we
      really need to see that it is all electrical, baby.

      Picture a living earth which has adapted to climate--but the sun is
      getting more lumenous. It reaches an unstable point where the oceans
      warm enough to melt the hydrates. Understand that the cirrus clouds
      cause a retention of heat, and the biosphere has up to this point
      enhanced that effect--the cirrus, by EMFs, either by increasing the
      insulation or the conductivity of a carrior of large scale low freq
      waves of EMF which travel from ground and ocean to cloud and then to
      ionosphere and back (Doran waves). Doran waves are powered by
      convection and the sun.

      The dynamic is HIGHLY tuned because minute changes in CO2 vary rain's
      conductivity and hence the whole global circuit. This changes how
      hydrology is fed back and how more Co2 might be produced by erosion
      or weathering.

      Hence, a melting of hydrates is going to have an immediate impact in
      that not just is there an issue of CO2 as a green house gas--but also
      EMF insulation of hydrates goes. That means things should cool down.
      BUT, the plankton goes, too, indicating that things are so warm there
      is no upwelling--that should cool things down too.

      From the same link:


      "The drastic changes were bad news for deep-sea plankton, which
      suffered widespread extinction. But the rise in temperature benefited
      mammals, which evolved into new forms and spread around the globe. "

      Mammels were evolved in the context of LESS modulation of a specific
      regions climate. Put another way--reptiles as cold blooded really
      serve Gaia in the sense that they are only active with warmer weather-
      -which confines their range to places where their "droppings" remain
      in the hydrology and therefore the biology.

      While such a melt even cause huge super sonic tropical storms?

      As far as big huricanes are concerneed--there is a real problem
      because big TS are electrical. Just because SSTs are warm doesn't
      mean that they are powerful in a linear model. To the contrary, it is
      my view that as waters get warm enough they are so conductive that
      they become quickly associated with the instabilities that are
      requred to be modulated--electrical in nature.

      Indeed, what may have caused the event 55 million years ago could
      have been electrical , too from space.
