Earth’s magnetic pole is on the move, fast. And we don’t know why. By Jamie Seidel.

Planet Earth is alive. Deep beneath its skin, its life blood — rivers of molten iron — pulse around its core. And this mobile iron is what generates the magnetic field that causes auroras — and keeps us alive. …

It’s causing the magnetic North Pole to ‘skitter’ away from Canada, towards Siberia. …

The liquid iron churning in the Earth’s core does not move in a consistent manner.

“In 2016, for instance, part of the magnetic field temporarily accelerated deep under northern South America and the eastern Pacific Ocean,” Nature reports.

The movement of the north magnetic pole has been the object of study since 1831. Initially, it was tracked moving into the Arctic Ocean at a rate of about 15 km each year. But, since the mid 1990s, it has picked up speed.

It’s now shifting at a rate of about 55 km a year.

Let’s see if some theory comes out blaming this on humans, to which powerful political agendas soon hitch their wagons — just joking. But could it be connected to climate change? It might.

South Atlantic Anomaly: Punching a hole in Earth’s radiation shield. Also by Jamie Seidel.

We’ve known for more than a century that our planet’s magnetic field has been weakening.

It’s what gives us our north and south poles. This powers our compasses.

It’s also a vital shield that protects us from harmful radiation constantly bombarding us from the Sun or deep space.

This weakening is most evident in one place. It’s a hole that reaches across the heart of South America, over the South Atlantic and into Africa.

It’s been dubbed the “South Atlantic Anomaly”.

It’s allowing more high-energy radiation to penetrate deeper through near orbit, the atmosphere and to our surface.

In recent decades it’s caused computers to crash on Shuttles and the International Space Station.

In 2016, Japan’s revolutionary Hitomi X-ray observation satellite that was supposed to study black holes and supernovas was struck while passing through the gap and sent spinning out of control.

Changes in radiation can affect the height of the tropopause at the poles relative to the equator, which can affect the path of the jet-streams, which affects the amount of cloud, and thus how much of the Sun’s radiation is reflected back out to space without warming the planet. There are several possible mechanisms like this that can affect temperature here on the surface.

In 2013 I found a solid link between solar activity and the Earth’s surface temperature (much more comprehensive and quantitative than the other links people have noticed) — something appears to be driving both sunspots and, after a delay on one sunspot cycle, global warming. I won’t go into the details here, but the upshot is that we predicted (in 2013) that global cooling will set in starting around 2017 give or take a couple of years — and the 2020’s will be cooler than the 1980s.

Since 2016 there has been the greatest fall in recorded global temperature ever … but that’s not saying much since records only started in the late 1800s. The prediction, so far, is on track, but with the usual variation from El Nino/La Nina it is far from confirmed.
