AN URGENT SIGNAL FOR THE COMING ICE AGE
By Peter Harris
INTRODUCTION
When paleoclimatologists met in 1972 to discuss how and when the present warm climate would end , termination of this warm climate we call the Holocene seemed imminent and it was expected that rapid cooling would lead to the coming ice age. These ideas were based on the 1M year analogue for climate transitions first proposed by Milankovitch over 60 years ago, which has been demonstrated to show the correlation of glacial and interglacial climate with solar insolation as it is modulated by our changing distance from the sun. These data sets may be used to serve as a signal for the coming ice age. Orbital geometry was approaching similar conditions to those of the previous transitions to ice.

But soon it was observed that global temperature was increasing and at about this time Global Climate Modeling GCM received more attention and the Milankovitch analogue was forgotten. There has been no further discussion about the coming ice age.u9

Precession, Eccentricity, and Axial Tilt changes are products of gravitational forcing. The Earth's wobble changes by degrees as its orbital ellipse changes. As the earth makes its maximally elliptical orbit corresponding changes occur to its axial tilt.


And Dr. Dewpoint adds more curiosity to the climate puzzle with his discussion of the Pacific multi-Decadal Oscillation (PDO)

Visit http://proa.accuweather.com In his archives, Joe Bastardi has published a substantiable argument on how the massive Indonesian earthquake interfered with the natural mechanisms for ocean temperature changes and necessarily climate that does address the recent exception years.

These readings are quite suggestive. If the warm phase of the PDO hid the onset of global cooling as a result of the earth's orbital positioning (including the decling tilt of its axis and corresponding frictioning wobbles) , then at what point did orbital positioning overtake the oceans as the climate driver? How close are we to the years without summer?

Now I return the discussion to eccentricity. Changes to eccentricity affect the earth's abiliity to harmlessly displace excess kinetic energy. The changes that occur to earth's orbital plane are identified as its Nodal precession. The inconstancy of earth's trajectory within its orbital plane is its way of resolving the inequalities of its gravitational relationship with the sun. The earth does not efficiently release the gravitational inequalities; some of this kinetic energy is absorbed by the earth itself and is dispersed tectonically. As a consequence, continental plates are broken and set into motion

Because Vulcanism is a phenomenon of plate tectonics we can also attribute eventuations to earth's eccentricity math. Erupting volcanoes add solar energy shielding sulfuric gases to the upper atmosphere. highly eccentric aphelion/ perihelion thus cycle glacial advances and albedo phenomenom to protect the earth from excess solar irradiance.


(***Nodal precession's vibrance is visibly equivalent to lunar tides***)



Physicists have advanced our understanding of Nonlinear Gravitodynamics.

****nodal precession is the micro wobbles ......The inclination of low-eccentricity orbits is shown to significantly affect the orbital parameters, in particular, the Keplerian, nodal precession, and periastron rotation frequencies, which are interpreted in terms of observable quantities. For the nodal precession and periastron rotation frequencies of low-eccentricity orbits in a Kerr field, we derive a Taylor expansion in terms of the Kerr parameter at arbitrary orbital inclinations to the black-hole spin axis and at arbitrary radial coordinates. The particle radius, energy, and angular momentum in the marginally stable circular orbits are calculated as functions of the Kerr parameter. By analyzing our numerical results, we give compact approximation formulas for the nodal precession frequency of the marginally stable circular orbits at various in the entire range of variation of Kerr parameter.
