Not by Fire but by Ice

Some say the world will end in fire;
Some say in ice.
From what I’ve tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
—Robert Frost, American Poet
Considering the thousands of absurd claims made about the discredited fraud of "global warming", a recent National Geographic News story, “North Magnetic Pole Moving East Due to Core Flux”, struck me as potentially far more significant.
“Earth’s north magnetic pole is racing toward Russia at almost 40 miles
a year due to magnetic changes in the planet’s core, new research says.”
Why is this of interest? Because ice ages recur every 11,500 years and
right now the Earth is at the end of the latest interglacial period,
i.e., the interim between ice ages.
At some point in the past 200,000 years Homo sapiens climbed down out of the trees, stood upright, and began their trek toward what we call civilization and civilization as we know it—the spread of agriculture and the rise of cities—is only about 5,000 years old.
The late paleontologist, Stephen Jay Gould, said, “We have not a shred of evidence for any genetic improvement since then. I suspect that the average Cro-Magnon, properly trained, could have handled computers with the best of us.”
The bad news about magnetic reversals is that they have often been accompanied by massive extinctions and, as noted, they return in a dependable, predictable cycle. “Mass extinctions,” says Felix, “have been the rule, rather than the exception, for the 3.5 million years that life has existed on this planet.”
Many scientists maintain that the last magnetic reversal occurred about 780,000 years ago at the Brunhes/Matuyama boundary, but in addition to full-scale reversals, Felix includes magnetic “excursions” in his calculations.
Magnetic excursions are times when the earth’s magnetic north pole moved south for a short while—sometimes as much as 500 years—and then moved back. Magnetic excursions are apparently aborted magnetic reversals, says Felix. They recur about every 11,500 years. And they are deadly.
The last one, the Gothenburg magnetic excursion, took place about 11,500 years ago. Is it just a coincidence that some 40 percent of the large animal species, including the sabre-toothed cat, the mammoth, the mastodon, and the great Dire wolf went extinct at the time? “No,” says Felix. “That was no coincidence.”
Nor is it a coincidence that more than one million huge elliptical holes - some the size of a small city - were blasted into the earth at the same time. Today, those huge holes are sometimes known as Carolina Bays, Grady Ponds, Maryland Basins, or, in Texas, Salinas.
Then there was the Mono Lake magnetic excursion of 23,000 years ago, when the earth descended into catastrophic glaciation, and the mammoths were almost decimated. And prior to that was the Lake Mungo magnetic excursion of 33,500 years ago, when the Neanderthal went extinct and the earth descended into yet another period of glaciation.
If this cycle holds true, says Felix, the next magnetic reversal——and extinction—is due any day.
A magnetic reversal would likely have a devastating effect on planet
Earth and, frankly, I don’t want to be around when it occurs.
