Earthquakes Increasing as Planet's Rotation Slows; Donald Trump to Blame

Timothy Birdnow

The Earth's rotation is expected to slow down next year, triggering an increase in earthquakes. according to new research by the University of Colorado Boulder.

According to an article in Livescience:

""The numbers of earthquakes that have occurred each year in the past century are well known. The changes in Earth's rotation rate are also well known," study co-author Roger Bilham, a geophysicist at the University of Colorado Boulder, said in an email to Live Science. "All we have done is to compare these two well-known lists of numbers and report an interesting and useful relationship

The basic idea is that as the Earth's spin slows slightly, the equator shrinks. However, tectonic plates don't shrink as easily, meaning the edges of the plates get squeezed. Although this amount of squeezing isn't huge, it does put added stress on plate boundaries that are already under stress, where earthquakes are more likely, Bilham said Bilham and his colleague, Rebecca Bendick, a geophysicist at the University of Montana in Missoula, looked at the history of earthquakes of magnitude 7 or greater since 1900.

On average, there were about 15 major earthquakes per year since 1900. However, during certain periods, the planet sees between 25 and 35 earthquakes greater than magnitude 7 in a year. When the team looked more closely, they found those periods coincided with times when the Earth spins more slowly, meaning the days get slightly longer. Changes in Earth's rotational speed can be caused by weather patterns like El Niño, ocean currents and currents in the molten core of the planet. When fluids speed up, the solid Earth must slow down, Bilham said.

Because NASA tracks the length of the day to the microsecond, these slowdowns in Earth's spin can be predicted five years in advance, Bilham said.

Based on that data, the Earth is entering a period of prolonged slower rotation. As a result, next year could see more quakes, if past data is any indication. Whereas an average year might see about 15 earthquakes of magnitude 7 or greater, the next four years could see closer to 20 earthquakes of that size, Bilham said.

"Knowing that earthquakes will be more plentiful in five or six or seven years is useful because if a city planning department is considering retrofitting buildings to make them earthquake-safe now, or in 10 years' time, the knowledge that more earthquakes are on their way may make them act now, rather than later," Bilham said."

So, the Earth's spin is slowing, earthquakes are going to increase, and no doubt Donald Trump will get the blame.

Don't doubt me; the claim is that the ice caps are melting and that this will increase the rate of planetary spin. It's not true; ice caps have been growing in recent years, not melting.

From another Livescience article:

" Previous research has found that melting glaciers triggered by global warming helped cause a significant amount of global sea-level rise in the 20th century. In theory, rising sea levels — once estimated to be climbing at a rate of about 0.06 to 0.08 inches (1.5 to 2 millimeters) per year — should also have slightly shifted Earth's axis and increased the rate at which the planet spins.

When polar ice caps melt, they remove weight off underlying rock, which then rebounds upward. This makes the poles less flat and the planet more round overall. This should in turn cause Earth to tilt a bit and spin more quickly."

End excerpt.

This article admits that there was much less glacial melt than models predicted, and they are quick to say that the problem has been corrected and the earth is heating up faster than John Conyers or Al Franken at a strip club. But satellite data shows no such ice melt and claims of increasing sea level rise are horse poo.

Actually, I'm rather surprised they admit that the Earth is the culprit; many environmentalists will no doubt try to blame hydraulic fracturing (fracking) for the new movement of the Earth's crust. But knowing these types, they will no doubt blame both, and anyone who argues against global warming nonsense.

We understand a lot less than the purveyors of climate hysteria want us to believe.
