Any Worry? The Supposed Decay of the Earth’s Magnetic Field, By Chris Knight (Florida)

I stumbled across this article by Pete Colan in American Thinker from December 2024, and it's got me thinking. It's all about how Earth's magnetic field is this chaotic, unpredictable beast that might be messing with our climate way more than we realise. Colan's got a bone to pick with the usual "CO₂ is evil" crowd, and he's digging into some real science to make his case.

Colan kicks off with this find: a 42,000-year-old tree in New Zealand, preserved like it's frozen in time. Scientists say it shows the Earth's magnetic field flipped back then, north became south, south became north. Apparently, this happens every 200,000 to 300,000 years, and we're overdue for another flip. Before it switches, the field gets weaker, fades out, then comes back reversed. It's like the planet's pulling a cosmic U-turn.

Fast-forward to now, we've got tech to track the magnetic field's constant twitches. Something called the World Magnetic Model gets updated every five years, last one was December 17, 2024, to keep GPS and navigation on point. Colan quotes a scientist, Nils Olsen, who says this thing's chaotic, like a dog chasing its tail. No patterns, no predictions, just a hot mess we can only watch.

Here's where it gets interesting: NASA and others say the magnetic field's been losing strength, down 5% in the last 100 years, 9% over 200. It's a steady slide, not just random jitters. Colan's like, "What's this mean?" Nobody's got a solid model to predict the fallout, but a weaker field lets more UV rays sneak through the ozone layer. That could be good or bad, maybe more vitamin D, maybe more skin cancer, or an effect upon crops. It's a domino effect, and we're just guessing what's next. Makes you wonder why nobody's shouting about this?

Colan asks: what if this magnetic fade is tied to climate? He points out sea levels have been creeping up super slow, 0.06 inches a year, for 140 years, no matter how much oil we burn or how many hurricanes hit. Coincidence? He's not saying it's aliens, but he's hinting the magnetic field might be a bigger player than CO₂. A 2023 study he mentions says a weak field 42,000 years ago, during something called the Laschamp event, trashed the ozone and maybe changed weather so much it wiped out Neanderthals and big animals.

Remember that ozone hole scare in the '70s? Colan wonders if CFCs and humans got too much blame. Maybe those magnetic wiggles were part of it, but we didn't have the tools to check back then. Now the hole's healing, and nobody's talking about it. He's like, "See? Science isn't settled." It's a fair point, feels like we're quick to pin everything on humans without looking at the planet's own tricks.

Colan's big beef is with folks who act like CO₂'s the only bad thing, and it is not even a bad thing. He cites a 2016 study saying magnetic field changes mess with the upper atmosphere's temperature and winds, way up at 100-500 km. Even some government engineers, Colan's not calling them scientists, are starting to admit the magnetic field matters for climate up there. But NASA? They're all, "No, it's not about climate change today." Colan's objecting, saying it's hypocritical to ignore this while freaking out about fossil fuel-powered vehicles. He's got a point: if the magnetic field's this unpredictable, why is it not in those fancy computer climate models used by climate change globalists?

Wrapping up, Colan's all about real science, asking questions, not swallowing answers whole. He's suspicious of climate narratives that skip over stuff like magnetic shifts, especially since we can't predict them. He's not saying your pickup truck's saving the planet, but he's calling out the hype around EVs and CO₂ as the end-all. It's refreshing to hear someone say, "We don't know everything, so let's keep digging." Makes me want to grab a telescope and start sleuthing myself.

This article's a wake-up call to look beyond the usual climate change BS. Colan's not pretending he's got all the answers, but he's asking the right questions about Earth's magnetic field and what it means for our world.

By Pete Colan

I caught wind of an article recently of a tree discovered in New Zealand estimated to be about 42,000 years old, remarkably preserved. Remarkable enough that it tells the tale of a reversal in the earth's magnetic field during that time.

Apparently scientists believe "Over the last 5 million years, the Earth's magnetic field reversed itself at least 20 times. Over the last 20 million years, the reversal happens about every 200 thousand to 300 thousand years; however, it is very difficult to predict when a reversal will occur… Before the Earth's magnetic poles switch, the magnetic field slowly gets weaker, fades out, and then reappears with the poles reversed."

On a time scale a bit closer to now, more recent technology allows us to map changes in the earth's magnetic field that occur constantly and the World Magnetic Model (WMM) is updated every five years which is critical for navigation and GPS. In fact, it was just updated on December 17, 2024

Are these shifts predictable? Not at all. Quoting from Nils Olsen:

"The magnetic field changes in a chaotic manner, and we do not know why it changes in the way it does nor how it will evolve in the future… There is no periodic behavior, and it is therefore rather difficult, if not impossible, to predict how the magnetic field evolves over time. We can just observe how it has changed in past and what it looks like today."

Overall, however, various NASA articles agree with other scientific measurements that Earth's magnetic field has been decaying about 5 percent over the past century, and about 9 percent over the last two centuries which indicates a near-linear overall decline unaffected by the short-term measured chaotic changes in the earth's magnetic field. The complexity of what that decay would do is overwhelming and uncertain. Yes, it would allow more UV penetration through a deteriorated ozone layer but that has both positive and negative effects as well as consequential effects of those effects and so on. No models exist that can predict the outcome over hundreds or thousands of years. All we can do at this point is draw correlations and hypothesize in true DoE (aka "scientific") fashion.

For one example, recall we've seen that same very slow (0.06 inches per year) linear rate of rise in global sea levels measured over the last 140 years unaffected by the exponential rise in petroleum and natural gas usage and spikes in temperatures measured here and there, hurricanes, floods, and all the things that "science" would tell us are indicators of "climate change." Coincidence? Maybe not... just postulating a hypothesis.

Other researchers believe that the health of the ozone layer and our climate greatly depend on the magnetic field strength and orientation. From an article published in 2023:

"The ozone layer damage caused by the severe weakening of the Earth's magnetic field during the Laschamp event (42,000 years ago) may have led to drastic changes in weather patterns. These changes may, in turn, have led to the extinction of most megafauna species and perhaps even the Neanderthals."

On a different subject, did humans and CFCs have anything to do with that hole in the ozone layer observed in the 1970s, or was it just a consequence of the unpredictable and chaotic geomagnetic excursions? Perhaps we'll never know, because we didn't have the tools back then to understand short-term localized changes in the earth's magnetic field that we have today, but the "science isn't settled" on this, and nobody's talking about it anymore because it seems that "hole" is healing.

Even though government-paid people with engineering degrees (I won't call them "scientists") still think CO2 is an evil gas that's going to kill us all, some are admitting that "changes in the Earth's magnetic field are more relevant for climatic changes in the upper atmosphere (about 100-500 km above the surface) than previously thought."

A study published in 2016 agrees that the impact of earth's magnetic field on the climate cannot be ignored:

Magnetic field changes from 1900 to 2000 cause significant changes in temperature and wind in the whole atmosphere system (0–500 km) in DJF

Direct responses form in the thermosphere and propagate downward dynamically, initially via the gravity wave-induced residual circulation

In the middle atmosphere, changes in planetary waves become also important, but these may not be correctly represented in the SH

However, our own beloved NASA seems intent on ignoring the very real possibility that fluctuations in the earth's magnetic field have anything to do with "today's climate change." Yes, during periods in earth's history of a reversal of the magnetic field there may not have been mass extinctions because some life survived while others perished, some evolved and some didn't, but then to turn around and draw the conclusion that me driving my ICE pickup truck is going to cause the oceans to swallow up Barack Obama's Martha's Vineyard mansion in the next few decades and driving an EV is the solution is just scientifically hypocritical.

This adds yet another layer of suspicion onto the millions of things we know nothing about that is not included in those "climate models" and because of its inherent unpredictability, it never will.

True science demands that we continue asking questions, not drawing conclusions and burying our head in the sand."
