First, the title is very misleading.

They inferred a "NEAR reversal" NOT "Magnetic Field Reversal"!!!!

Second, Nobody explains the uniqueness of finding a 40,000 year old tree that HAS NOT BEEN PETRIFIED!!!!!!

Third, they don't explain how the tree rings revealed changes in the Earth's magnetic field.

I remember back in 1968 or 69, SAGA magazine had an article on how the poles would reverse, allowing the crust of the earth to slide around, destroying cities.

Then when the magnetic field reestablished itself, the crust would be stable, but you would not know where on the earth you would end up.

There was a great illustration of skyscrapers falling as everything collapsed.
I kept that article for years because of the illustration. Wish I still had it.

Think of the fortune in lumber that could be milled from that thing. How many 40,000 year old table tops could you make from that, and what would people pay for them -- a lot I'd guess.

My neighbor is an immigrant from New Zealand. He has some amazing stories about these Kauri trees. They have been growing there for at least 150 million years. Even today, there is big money locating these ancient trees underground. The most expensive wood in the world.

Swamp kauri

"Swamp kauri, sometimes marketed as "ancient kauri", are prehistoric kauri trees (Agathis australis), buried and preserved in peat up to 50,000 years ago in New Zealand's North Island.[1][2] Buried under a peat swamp by an unexplained act of nature at the end of the last Ice Age, the trees have survived the centuries underground, sealed in a chemically balanced environment that has preserved the timber in perfect condition.[3]"

"The trees grew for nearly 2000 years before they were buried. Some have a girth of around 40 feet, and a total height of nearly 200 feet."

Earth's magnetic field is thought to be generated by the iron in the planet's core. As it moves around, it produces electric currents that extend far into space.

I'll have to locate one of those. Plug in, free electricity for ever!

Lol.. mythical dating science. I believe their claim the hymalayas will melt by 2020 before I believe this drivel. I can’t believe this is still considered science by anyone.

Q; How many Poles does it take to reverse magnetic fields?

A: Just two.
