Someone once remarked that "skeptics" of the knee jerk variety, the kind who publish mysteriously funded magazines, are actually the ultimate true believers, who believe (or profess to believe) in the status quo, atheism and materialism. Those of us who no longer accept this belief system, and who are interested in such fortean phenomena as ufos and lost civilizations, owe it to ourselves to be true skeptics and not believe without question. Yet a great many people who think of themselves as open minded believe, with no evidence, in such things as a hollow Earth Sirian motherships, or pole shift.
Pole shift, of course, refers to the theory, first popularized by Charles Hapgood, that the entire crust of the Earth can suddenly, in only a few years or less, slide as much as thirty degrees or so over the mantle, moving polar caps into warmer latitudes and bringing ice free zones into polar areas, forming new ice caps.The theory has been used to explain the ice ages, when much of northern Europe and northern North America was covered by immense glacial ice caps. Proponents of the theory suggested that the weight of polar ice caps causes an imbalance, so that, eventually, angular momentum pulls the ice caps (and the entire crust with them) toward the equator of the spinning Earth. This is just the kind of bold, innovative thinking that is needed to shake up the status quo now and then.
Unfortunately, there is no convincing evidence to support the theory, and a great deal of evidence that it is dead wrong. No one doubts that the Earth's magnetic poles, offset for unknown reasons from the axis of rotation, slowly wander around (again, for unknown reasons). At intervals, the Earth's magnetic field slowly weakens (it is doing so now, at an ever-increasing speed), finally dying out and then reforming with its polarity reversed. Again, no one knows why; in fact, it is a dirty little secret of astronomy and physics that no one knows why such very different celestial bodies as planets, stars, and black holes even have magnetic fields. Plate tectonics would seem to explain the fact that different landmasses have slowly drifted into and out of the polar regions over aeons of time, but this is a far cry from sudden and catastrophic pole shift.
The theory was originally advanced to explain the ice ages, but the problem with understanding the ice ages is not that we don't know what caused them, but rather that there are too many causes.Earth's 25,920 year axial wobble subtly changes the timing and distribution of solar heat absorbed by our planet.The ellipticity of Earth's orbit slowly changes. Atmospheric carbon dioxide levels have varied for millions of years with no help from Al Gore,but only the most major changes seem to affect climate, if at all; commonly, temperature increases coome before, not after, CO2 changes.When continental drift leaves open ocean over both poles it is next to impossible to have the ice buildup needed for an ice age; conversely, at present, Antarctica covers the south and the Arctic Ocean is partly enclosed, allowing the buildup of sea ice with less disturbance from ocean currents.Mega volcanoes put dust and sulfurous acid droplets into the upper atmosphere, blocking sunlight, resulting in a cooling that can trigger a full-fledged ice age if other conditions are suitable. In fact, the Indonesian volcano, Toba, produced such a super eruption just over 75,000 years ago, and then the last ice age began.And finally, the Sun's energy output varies with the eleven year sunspot cycle, and more extreme variations take place over longer intervals of time. Since the Sun is the major creator of our climate, it is not hard to see why this alone might cause ice ages.At least part of the most recent cool period, the Little Ice Age that began in the fourteenth century and lasted well into the nineteenth century, coincided with the Maunder Minimum, when reduced sunspot activity indicated a reduction in solar energy output.Our problem is trying to understand how all of these factors interact.
Ane merely moving the ice caps around, as in a pole shift, would be unlikely to produce a great deal more ice; it is simply being redistributed.Yet there is overwhelming evidence that during the ice ages there was a great deal more ice;the rocks show the movement of glaciers over vast areas and there is overwhelming evidence that sea levels were as much as 400 feet lower during the peak of the last ice age, which was caused by so much water being locked up in the ice sheets. Proponents of pole shift like to point out that much of Siberia was ice free during the last ice age, but this proves nothing, since large areas of Siberia and Alaska are ice free today, despite being further north than large parts of Greenland that are covered by the world's second largest (after Antarctica) ice sheet.There are other factors involved, mainly cloud cover and snowfall.
If the entire crust of our planet shifted even a few degrees, even over a period of several years, there would be an enormous amount of energy released. It might be enough to melt the entire crust and annihilate all life; it would certainly at least cause massive volcanic eruptions.Yet there is no evidence for any great increase in vulcanism at the end of the last ice age. Worse, the Earth has an equatorial bulge caused by its axial spin, so that neither the Earth nor its crust is exactly spherical. This means that even a slight slippage would cause widespread shattering of the crust as it compressed in some areas and stretched in others, resulting in sudden mountain building and even more vulcanism. There is not the slightest geological evidence for any of this. This is not to say that the end of the last ice age was not catastrophic, but merely that it was not as catastrophic as crustal slippage would be. The sudden climate change and sea level rises were bad enough, and there is now some evidence of a comet explosion over North America that may have contributed to the extinction of much of the Pliestocene mega fauna.
In fact, there is even direct evidence that the crust has not slipped, but rather that the slow process of continental drift has continued without interruption for millions of years. The newest and most active Hawaiian volcanoes are in the southeast, where Kilauea erupts almost continuously and a new volcano is emerging from the sea floor.To the northwest, Mauna Loa is less active; further northwest, Mauna Kea, crowned by some very expensive observatories, is mercifully silent. Haleakala, on Maui, is considered dormant but is more likely extinct, and the island of Kauai, jagged and eroded, is older than the Big island or Maui.Midway Atoll is eroded almost to sea level, and the Hawaiian chain last breaks the surface far to the northwest with the ancient French Frigate Shoals. Conventional gelogists have a good explanation for this. Plate tectonics slowly moves the sea floor and the islands over a hot spot, or mantle plume, and the crust moves from southeast to northwest.Similar evidence is found elsewhere, in many locations. Much of the Columbia and Snake River Plateaus were caused by massive flood basalt eruptions, with the most recent eruptions to the east, at Craters of the Moon National Monument, and, further east, the Yellowstone caldera.This is almost certainly caused by the westward drift of the North American plate and continent over a hot spot that is presently under Yellowstone. A similar chain of volcanoes stretches across Canada, producing diamond deposits and the hill that is the namesake of Montreal. This hot spot is now under the Atlantic, as our continent has moved west of it. None of these chains of volcanoes would exist if pole shift was a reality.
Canadian author Rand Flem Ath, apprised of some of these problems by one of his readers, modified the theory and suggested that the entire mantle, along with the crust, has slipped. But why stop there? Why not include the core as well? Either way, it still does not explain the increased ice sheets and lower sea levels. And it is doubtful that the weight of ice sheets would be sufficient to move even the crust. What unknown force could possibly move the mantle as well? The Earth is an immense and very stable gyroscope, and most of the angular momentum (mass times velocity) that gives it this stability is in the mantle. The crust has less mass and the core has less velocity.
No, it is time to admit our error, bury pole shift once and for all, and move on. Let the "skeptics" be the true believers. We will be the real skeptics. William B Stoecker
