An ancient tree that contains a record of a reversal of Earth's magnetic field has been discovered in New Zealand. The tree -- an Agathis australis, better known as its MÇori name kauri -- was found in Ngawha, on New Zealand's North Island, during excavation work for the expansion of a geothermal power plant, stuff.nz reports.
The tree, which had been buried in 26 feet of soil, measures eight feet in diameter and 65 feet in length. Carbon dating revealed it lived for 1,500 years, between 41,000 and 42,500 years ago...
The lifespan of the kauri tree covers a point in Earth's history when the magnetic field almost reversed. At this time, the magnetic north and south went on an excursion but did not quite complete a full reversal.
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. The magnetic field acts as a barrier, protecting Earth from the solar wind. This is a stream of charged particles from the Sun that could strip away the ozone layer if it were to impact the atmosphere.
When the magnetic field reverses -- or attempts to -- it gets weaker, leading to more radiation from the Sun getting through. Previously, scientists have linked extinction events to magnetic field reversals.
The newly discovered kauri tree's rings contain a complete record of a near-reversal -- the first time a tree that lived during the entire event has ever been found. "It's the time it takes for this movement to occur that is the critical thing...We will map these changes much more accurately using the tree rings," Hogg told stuff.nz.

That's where the toy companies get wooden soldiers.
That's the analog representation of the BRA instruction in ML.
Thanks 21Twelve. This probably happens on Cyrinx as well. :^)

That tree clearly needs to be made into a stairmaster.
“How many of his beliefs were mocked twenty years later?”
You calling lobotomies weird? (I already mock some of their current practices.)
That’s ok. Dendrochronology has only been around
for five hundred years or so. Once you accept it,
we’ll move along to electro-magnetism.
Quote from a dear old friend: "I'd rather have a bottle in front of me than a frontal lobotomy."
I will accept the 500 years of proven experimental science. I will not accept 5 million billion years of it.. No one was conducting and recordeing exoeriences then.. thats the difference between real science and agenda driven extrapolation.
After mt st Helens proved you can not use todays processes to measure “pre “history”.. I learned a lot about fake science. If I used their methods in my science career thousands would have died.
Wonderful read. Thank you.
My pleasure.

I've rounded up a few backstory topics and bumped 'em a little.
