Climate Change has Shifted Earth’s Axis

While Earth’s Axis periodically Shifts by itself, the Effect is being Exacerbated by Human Activity’s effecting Climate, Researchers found.

Melting Glaciers and Changes in Land-based Groundwater Storage have skewed it even further, the American Geophysical Union reported in a Study Published last week in its Journal Geophysical Research Letters.

As Land-based Ice has Melted, much of it caused by Human Activity, the Movement of the North and South Poles is being Altered, Researchers found.

During the Mid-1990s, Melting Glaciers Redistributed so much Water that it Changed the Direction of the Routine “Polar Wander” to Not only turn Eastward but also Accelerate, the Researchers said in a statement.

The Average Drift Speed between 1995 and 2020 Increased about 17 times from the Average Speed between 1981 and 1995.

“The faster ice melting under global warming was the most likely cause of the directional change of the polar drift in the 1990s,” said Shanshan Deng, a Researcher at the Institute of Geographic Sciences and Natural Resources Research at the Chinese Academy of Sciences and the University of the Chinese Academy of Sciences, one of the Study Authors.

While Earth’s Axis periodically Shifts by itself, the Effect is being Exacerbated by Human Activity’s effect on Climate, Researchers found.

Geologic Shift itself isn’t a surprise, but the apparent Indirect Effect of Human Activity on it in Modern times is.

Global Ice loss has Sped-Up over the Past Two Decades, from approximately 760 Billion Tons per year in the 1990s to more than 1.2 Trillion Tons Annually since 2010.

“Reversals are the rule, not the exception,” NASA said in an Explainer on Polar Shifts in General. “Earth has settled in the last 20 million years into a pattern of a pole reversal about every 200,000 to 300,000 years, although it has been more than twice that long since the last reversal. A reversal happens over hundreds or thousands of years, and it is not exactly a clean back flip. While it has crept northward by more than 600 miles since the early 19th century, which is when explorers First pinpointed its location, it has sped-up, migrating northward about 40 miles per year, up from 10 miles per year in the early 20th century,” NASA said.

What the New Study does, is give a Reason for some of the Characteristics and Speed of the Shift.

“The Earth’s rotation is akin to that of a spinning top,” said University of Zurich Climate Scientist, Vincent Humphrey, in the statement. “And a top wobbles if the weight is redistributed,” he said in the statement, though he was Not involved in the current Research.

“NASA emphasizes that overall a pole shift is not a doomsday scenario — though a study earlier this year hypothesized that flipping poles around 40,000 B.C. helped sink the Neanderthal species. However, shift of the magnitude found in the study would not affect daily life.” Humphrey said.
