At the beginning of each ice age earth's rotation reverses while earth's axis goes perpendicular and precession ends.
  The Serpent at the End of Precessionby Michael W.WeirWhen the United Nations Framework Convention on Climate Change drafted the KyotoProtocol and presented it in 1997 to world governments as a way to reduce greenhousegas emissions in an effort to curb global warming, an international consensus was madeto turn away from earlier concerns over evidence of a looming ice age.Growing recognition to the failures of science to adequately define the causes of ice agecycles has left an appropriate lack of concern by those who are in positions to set a socialpolicy of awareness. As ex-vice president Al Gore took on the role of self appointed gurufor public awareness on global warming with his movie  An Inconvenient Truth , theresulting public acceptance of global warming as the new burden of guilt cemented thefocus away from the real threat facing modern society.According to Al Gore global warming is a blame game: “We are melting the North Polarice cap. . . .We are destabilizing the massive mound of ice on Greenland . . .” and “Weare dumping so much carbon dioxide into the Earth’s environment that we have literallychanged the relationship between the Earth and the Sun.” (1)  Without denying the changes taking place with global weather patterns and the very realhuman contribution to the greenhouse gas CO 2 , there are other forces involved that areaffecting Earth’s weather that we can not be blamed for nor can we prevent.Buried in the ash of past Yellowstone eruptions lies an unrecognized cycle of Earth’sgeologic history that directly threatens modern society. This cycle reveals a newfrequency of occurrence regarding each passage of the solar system through the galacticplane and its link to the duration and definition of glacial cycles. Understanding thismissing cycle should lead to a better awareness of the reality behind the next impendingice age and the political agenda behind the global warming scheme.Stimulated by evidence of changing weather patterns, a 1973 report from the CIAconcluded “a global climatic change is taking place and that we will not soon return tothe climate patterns of the recent past.” (2) This was soon followed by the 1975 FirstMiami Conference on Isotope Climatology and Paleoclimatology where Nobel laureateWillard R. Libby warned “Ice ages have been the normal condition during the last severalmillion years, with temperate climates enduring only five percent of the time . . .Becausethe global food supply depends primarily on climate, current understanding of climatemust be vastly improved…” (3)  Nearly thirty years later in a report released in 2004 the Pentagon was still expressinggrave concern over the changing climate and, while opting for either a scenario similar tothe climate change 8,200 years ago when the weather decayed for only one hundred yearsor the Younger Dryas event of 12,800-11,500 BP that cooled earth over one thousand  2years, the report still found in the projected future “a significant drop in the humancarrying capacity of the Earth’s environment.” (4) .Even within the stability of our present interglacial period, variability of sun spot activityor unpredicted changes in the North Atlantic thermohaline circulation can cause severeagricultural disruptions as seen in the Little Ice Age (LIA) that occurred between thethirteenth and mid seventeenth century.At the coldest point of the LIA little to no sunspot activity was noticed and frost wasoften to be expected in July throughout parts of Europe and North America. What effecthigh atmospheric concentrations of CO 2 could have on a period of sunspot minimum isundetermined though the threat is real enough and possibly soon to be realized, as solarcycle 25, which begins in the year 2013, is expected to be one of the most inactivesunspot cycle in centuries. (5) The impending cooling of solar cycle 25 could very well beresponsible for fueling the hopeful speculation that global warming may possibly delaythe onset of the next ice age. (6) The beauty of the Milankovitch Theory (MT) of ice ages is its mathematicalpredictability and linear gradualism. All three predicted cycles happen over extendedlengths of time – the shortest cycle, precession, being a mere 23,000 years. Certainly thismay seem enough time to put off concern of climate change for further generations or, if we happen to be the generation that has to deal with it, plenty of time to come up with ameans to social and economic adaptability before the situation became severe.Only the MT doesn’t explain enough. This is why our government is so concerned overimprovements in understanding current climate change. Milutin Milankovitch came upwith his theory over eighty years ago and, as nice as it looks on paper, it is failing morefield tests and ultimately lacks explanation for periods of severe climate reversals.According to the MT we are in the best position for the shorter precession cycle, winterfalling in the northern hemisphere while the earth is closest to the sun (perihelion), alongwith earth’s cycle of obliquity, both presently optimum – just the right amount of sun fora stable climate for both hemispheres, and there’s no indication of a looming ecliptic shiftor orbital stretch.Yet, amidst a crescendo of global warming soothsayers and a scramble to create carbonexchange proposals for CO 2 emitting corporations there’s at least one geologist saying“our time looks about up” before this warm interglacial period comes to an abrupttermination. (7) Sixteen years ago science got a big clue to the shortcomings of the MT. Based on isotopicanalysis overlaid on the Milankovitch orbital cycles, discoveries in 1992 at Devil’s Hole,Nevada, showed cycles in climate fluctuations that are not in sync with the MilankovitchTheory. Orbital-forced insolation (cooling by increased distance from the sun) increasescould not explain it. (8)    3With a chart that shows three million years of temperature fluctuations based on oxygenisotope profiles, University of California, Berkeley professor Richard A. Muller pointsout problematic discrepancies with Milankovitch. In the last 650,000 years the ice age isdominated by only the 100,000 year glacial cycle while the previous two million yearshas a predominant 41,000 year cycle and then about three million years ago there were nostrong ice age cycles at all.This problem, the problem being the lack of a dominating MT of orbital forcing, has leadMuller to believe “that the driving force is astronomical.” (9) In other words, orbitalvariations as a major mechanism for global cooling seem less likely than some otherfactor beyond earth such as interplanetary or galactic dust clouds.A different chart of temperature compilation going back only 420,000 years illustrateshow short the warming periods are between glacial building events of the last ice agecycle. Even though these warming events may comprise 10% or more of the precedingglacial period, in Muller’s words, “such interglacials are very brief”. (10) By thisreckoning we are way past the ten percent grace of the last 100,000 year glacialmaximum.  4What historians determine to be the total length of time it took for modern civilization todevelop is all within our present interglacial period. Sharp spikes in the graph not onlyillustrate how quickly ice ages can end, but also how quickly they can begin. “This datashould frighten you . . . the next ice age is about to hit us,” warns Professor Muller. (11)  How fast global climate can change was pointed out by Jeffrey Severinghaus, head of Scripps Institute of Oceanography, when, after analyzing ice core samples from bothGreenland and Antarctica, he found climate reversals to be noticed in as little as threeyears, in one sample an incredible nine degree temperature change happened within adecade. (12) A large part of the failure of climatologists to find a better explanation for ice ages is theapplication of the spinning top model for earth.A spinning top implies a single given momentum and a drag or torque against the axis of the spin. This is a misleading image of earth’s rotational relationship to its orbital plane.A gyroscopic effect model is closer to the real model and even this can give the wrongimage of earth’s stability. Due to the presence of the moon, earth’s obliquity can not gopast the twenty three degrees of the lunar orbit.What a gyroscopic model does best is illustrate the relationship of the moon to the earth’sequatorial bulge, a suggestion of the lunar tidal drag against earth’s speed of rotation, andthe cyclical changes in the moon’s own orbital plane which in turn controls the degree of earth’s obliquity.But again, unlike a spinning top, Earth’s tilt pivots on the solar plane that dissects earth’sequator, not its bottom axis. The torque against the axis that a spinning top willexperience is not a proper representation of what is happening to earth. The only torqueon earth’s spin is caused by the moon’s influence against earth’s equator, an influencethat absorbs and modifies additional influences by both the sun and Jupiter. (13)
