40,000-Year-Old Tree Shows What Happened During Earth’s Last Magnetic Pole Reversal

Most people think tree rings are primarily used to tell the age of a tree and secondarily to make furniture look better. Believe it or not, there’s so much more that can be found in tree rings that an entire scientific field – dendroclimatology – is devoted to the study of climate and atmospheric conditions during different periods in history that can be revealed by analyzing tree rings. Excited dendroclimatologists are shaking like redwoods in a California quake at what they might find in the rings of a well-preserved kauri tree from about 41,000 years ago found buried in a swamp in New Zealand. One thing they won’t find is end tables and bookcases. However, what they will find is a bark-encased picture of Earth’s last magnetic polar shift – an event that is quickly occurring again. Did the rings reverse too?

“Over a period of 200 to 300 years, the virtual geomagnetic pole moved in clockwise fashion from its original northern position, traveling well into the Southern Hemisphere before swinging north again. If this were to occur at present, it would probably have significant implications for modern technology because very much stronger cosmic radiation impinging on the Earth’s surface would almost certainly impact upon satellites and communication. We do not need to be alarmist over this but it is important to know just how quickly these changes can occur.”

Kauri tree

It’s too late to not be alarmist, since the news about the magnetic North Pole moving to Siberia and on to the Southern Hemisphere has already been on Twitter, conspiracy sites and the mainstream media. However, Alan Hogg, director of Waikato University’s Waikato Radiocarbon Dating Laboratory, say studying the rings throughout this monstrous 16-meter-long (52.5 feet), 2.5 meters wide (8.2 feet), 60-ton log will reveal exactly how radiocarbon changed during its life span. That life span, which was estimated to be between 1500 and 200 years, began about 42,5000 years ago near what is now Kaikohe, a town in the Far North District of New Zealand. The kauri (Agathis australis) was found in late March in a massive swamp during excavations for a new geothermal power station near Ngāwhā Springs. The tree was preserved in clay 9 meters (29.5 feet) underground and the ends had to be cut off to move it. during site works for the new power station.

”It feels like it’s being returned to its rightful owners.”

Project site manager Mike Ohs gave the tree to local Maori leaders, who, after finding out it may be the only tree ever discovered from the Laschamp Event, the most recent reversal of the Earth’s north and south magnetic poles, allowed researchers like Alan Hogg and Professor Chris Turney from the University of New South Wales, an expert in paleoclimatology and climate change over the past 40,000 years, to study it. their initial reports in early July confirmed the tree’s age.

“We will be comparing results from dating this tree with dating from other sites to build a clearer picture of past climate changes.”

The tree was part of a vast kauri forest which covered the upper North Island and was exposed to the climate change caused by the Laschamp Event. While traumatic, it obviously survived, as did the kauri forests until the 1820 arrival of Europeans with axes, saws and a burning desire to cut down trees. It’s estimated that only 4 per cent of that original forest now remains.

What will this tree reveal about the last magnetic pole reversal … and the next one? What will it tell us … and possibly warn us … about climate change?

Forget the phony time travelers. This kauri is a true time machine.

A bright fireball exploded over Armenia

Yesterday, a very bright fireball exploded over Armenia. This was announced by the head of the meteorological forecast department of the Hydrometeorological Center Gagik Surenyan on Facebook. The magnitude (brilliance) of a celestial body, which entered the Earth’s atmosphere with great speed, is at least 12.

On the evening of May 27, local residents saw a luminous ball flying from the sky, when it collided with the ground, an outbreak occurred.

Users of social networks began to share their guesses, but they officially gave a comment at the  Hydrometeorological Center  only the next day:

“Yesterday’s fall of a large meteorite in the Hrazdan  -Hankavan section  ,” Gagik Surenyan wrote, head of the meteorological forecast department of the Hydrometeorological Center and posted a video showing the meteorite.

Those who also saw the meteorite offered to go to the site of the fall of the celestial body and “collect the pieces”, others reproached the authorities and scientists for silence, when everyone discussed the event, no one began to confirm to people that the luminous ball was a meteorite.

“A meteorite is the final act of this nightmare year,” users of social networks wrote a comment on the video, with sad irony.

The camera was installed in the vicinity of Hrazdan and was directed towards the village of Hankavan.

“The meteorite, judging by the records studied, was very large and entered at great speed the atmosphere of the planet, where it burned at an altitude of several kilometers. The risk that parts of this fireball could reach Earth is small, and the likelihood that they can be somehow found tends to zero, including the woodland and the fact that, when burned, meteors and fireballs crumble, as a rule, for particles up to several millimeters in size,” astrophysicist R. Martirosyan said.

Powerful sprites over Kansas were visible to the naked eye

Have you ever seen sprites? They say that this is impossible. Strange and fleeting forms of Red Lightning materialize over thunderclouds, usually disappearing in less time than it takes to blink. However, storm hunter Michael Havan had no problems seeing them on May 23rd.

“The extremely bright jellyfish sprites were easily visible to the naked eye at dusk!” Says Gavin. “This is one of the brightest shots I’ve captured with my modified Canon T3i.”

Gavin saw this sight from Northwest Kansas. “Clear skies provided fantastic views of the MCS (mesoscale convective system) moving through Nebraska almost 100 miles from us,” he says. “I was not the only one who saw them.” There have been reports that people also saw sprites from Interstate 70. “

The storm lasted so long that Gavin managed to attach an 85mm lens to his camera for several close-up shots. “Because I had an image of the same area without a sprite from a few seconds earlier, I was able to subtract the sky (stars, air glow, etc.) to take a photo of the structure of the sprite without any distractions.

A solar minimum can stimulate sprites. During the low phase of the solar cycle — now occurring — cosmic rays from deep space penetrate the inner solar system relatively unhindered due to the weakening of the Sun’s magnetic field. 

Some models claim that cosmic rays help sprites get started by creating conductive paths in the atmosphere.

By the way:

Today, May 25, 2020, the level of cosmic rays crashing onto the Earth, reached its maximum levels, increasing today by 10.4% of average values.

Cosmic rays 

The magnetic field of the sun is weak, which allows additional cosmic rays to penetrate the solar system. Neutron counts from the Sodankylä Geophysical Observatory of the University of Oulu show that cosmic rays reaching Earth in 2020 are close to the peak of the space age.

A surge in volcanic activity threatens the Earth with a new Ice Age

Over the past few days, we have witnessed a turbulent global volcanic surge in activity. He sends us all signs that the Great Solar Minimum is approaching.

The Japanese meteorological satellite HIMAWARI-8 recorded two powerful eruptions on May 16, both of which occurred in Indonesia.

The first took place in IBU – a relatively new volcano with only 3 noticeable eruptions; in 1911, 1998 and 2008 – and was confirmed by Darwin Volcanic Ash Advisory Center (VAAC), which warned that the ash plume rises to about 13.7 km.

The second high-level eruption occurred just a few hours later on Semera – a very active volcano with an eruptive history; the first happened in 1818, the most recent in 2014.

As with IBU, the Semeru eruption was confirmed by both HIMAWARI-8 and VAAC Darwin, the latter confirming the generation of a “dark ash plume that reached a height of 14 km.

In addition, active lava flows remain active on the southeastern flank of Semeru, currently about 1.5 km long (as of the morning of May 18).

Direct cooling effect

These high-level eruptions are notable for the fact that solid particles are thrown to a height of over 10 km – and into the stratosphere – are often delayed, where they have a direct cooling effect on the planet.

Volcanic eruptions are one of the key factors pushing the Earth toward its next round of global cooling, with their worldwide surge associated with low solar activity, coronal holes, a diminishing magnetosphere and the influx of cosmic rays penetrating silica-rich magma.

In addition to Indonesia, Icelandic volcanoes have intensified, and it is this high-mountain volcanic region of the world that is believed to be home to the next “big eruption” – one that will plunge the whole world into the new Ice Age almost instantly.

Katla is such a volcano here and it shows signs of activity, since a significant gas output has been recorded over the past few days. 

In addition, seismic activity under a large ice volcano has also increased, and this activity is probably caused by injections of new magma entering the chamber.

Icelandic authorities are aware of the danger posed by the next Katla eruption, and a delegation of volcanologists regularly meets with the Icelandic parliament to discuss how to respond in the event of an eruption, the likelihood of which is simply a matter of when, not if.
