Robert Coe



Coe is an emeritus professor of geophysics, and has had a long and distinguished career. He has received numerous awards and recognition for his many research accomplishments. He received his Ph.D. at the University of California, Berkeley, and did postgraduate work in Australia before returning to the States where he joined the UC Santa Cruz faculty in 1968. He has made significant contributions in a number of areas, including volcanology, geochemistry, and tectonics. In the 1970s, he developed a method of more accurately measuring the intensity of the magnetic field in rocks – a method that bears his name. Perhaps his most significant contribution, however, has been in paleomagnetism, where he has been a pioneer in the study of magnetic field reversals. “The Earth’s magnetic field is restless,” said Coe in a recent interview.

It seems clear they are all searching for answers and they have a lot to learn about our plants systems.

So the sun and moon could cause the changes makes sense to me.



The Earth continuously receives 3,700 billion watts of power through the transfer of the gravitational and rotational energy of the Earth-Moon-Sun system, and over 1,000 billion watts is thought to be available to bring about this type of motion in the outer core. This energy is enough to generate the Earth's magnetic field, which together with the Moon, resolves the major paradox in the classical theory.

So the tree grew 42,000 years ago, and shows it living through the magnetic flip (or whatever), but you're saying the last reversal was 780,000 years ago. There's some incorrect math there...


From the article:

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.


So it witnessed an "almost" reversal 42,000-ish years ago.

That doesn't quite jibe with the more definitive language in the title of the article Ancient Tree With Record of Earth's Magnetic Field Reversal in Its Rings Discovered, but maybe they consider a partial reversal to be a reversal [shrugs].

I am not a scientist but I recall planes having to make computer adjustments every time when landing due to the pole shifts and they still have this issue as of today.

Well maybe they do for local magnetic anomaly not pole shift I would think.


Runways are designated according to the points on a compass, and the drifting magnetic north means that they, periodically, need to be renamed. "Recently, the drift has caused our runways' orientations to be closer to the next increment on the magnetic compass," Tampa International Airport spokeswoman Brenda Geoghagan

That would then be one of the smaller one the excursions, which they don't know if our next will be or a full one. This could show though what I have seen argued that it can happen in less than 100 years (ours has been going on since what was it mid 1800) or can it happen in days, or does it always take longer.
With a partial will it cause death and destruction or will we be ok. I would bet it would weaken the field and we would be had if there is a bad solar flare.



Called a “geomagnetic field reversal,” this has resulted in the poles swapping positions, with magnetic north becoming magnetic south, and vice versa. The magnetic pole has also undergone what are called “excursions.” During an excursion event, the earth’s magnetic field weakens and begins to drift but does not reverse itself.

They use those numbers too.


During the past 100 million years, the reversal rates vary considerably. Consecutive reversals were spaced 5 thousand years to 50 million years. The last time the magnetic field reversed was about 750,000 - 780,000 years ago. While we now appear to be in a period of declining magnetic field strength, we cannot state for certain if or when a magnetic reversal will occur.

What if we are really already seeing effects, bold mine.




Will a reversal of the magnetic field affect animal behavior? Many migratory animals use the geomagnetic field to orient themselves. However, the mechanism underlying this ability of animals remains unknown. Experiments show that migratory birds can sense the declination and inclination of the local geomagnetic field.

Changing the polarity of the horizontal magnetic field is known to affect the hanging position ofbats. Some migrating butterflies use the geomagnetic field for direction. In the ocean,spiny lobsters, dolphins, and whalesare known to use geomagnetic field for directions. It is thus, possible that a reversal of geomagnetic field affect the migratory behavior of some animals. Since the chance of a reversal in the near future (in the next few hundred years) is very low, no immediate concern is required.


BUTTERFLY



But the 2018 Western Monarch Thanksgiving Count found that the number of west-coast monarchs spending the winter in California had plunged to only 20,456 butterflies—a drop of 86 percent since last year. And the number of eastern monarchs overwintering in Mexico this year has dropped 15 percent since last year, for a total decline of more than 80 percent over the past 20 years, according to the National Wildlife Federation.

BIRDS



It’s never good news when birds – or any other animals for that matter – fall from the sky … dead or alive. Get ready for some bad news from Draper, Utah, and Rome, Italy, where hundreds of dead starlings covered the ground recently. Pollution? End times? Something worse?

BATS
They say it is a fungus killing them



That now seems doubtful. And scientists predict that the once common little brown bat (Myotis lucifugus), will be reduced to just 1% of its pre-WNS population numbers by 2030.

LOBSTER



The lobster industry in New York and southern New England has nearly collapsed. From 1996 to 2014, New York’s registered lobster landings dropped 97.7%—from 9.4 million pounds in 1996 (the state’s most profitable year) to 215,980 pounds in 2014 (the latest data available). The story is much the same in Connecticut, where landings fell 96.6% from the most profitable year, and in Rhode Island, which saw a 70.3% drop from its most profitable year.

WHALE



So many gray whales are dying off the U.S. West Coast that scientists and volunteers dealing with the putrid carcasses have an urgent request for coastal residents: Lend us your private beaches so these ocean giants can rot in peace.

Remember the changes they had to make recently to the airport runways?


just for context - remind us

bear in mind - runway markings - are rounded to " nearest 10 degrees " ie 274 degrees is marked as 27

and most important - when was the last update to runway markings at the site ?

i hace a book detailing " the wwii eara RAF establishments in the UK " . and its interesting to compare 1940s runway designations - with the current ones [ at places where the RAF still operate - or have been turned over to commercial // recreational aviation ]

bottom line - the upgrades to runway markings - has been miss-understood and over hyped by doom poor munkies

Judging by the whole planet is ripping open,magnetosphere out of control,solar bursts,yes I would say we are headed for a reversal,think of a quadrillion plus train comming to a complete stop,then changing to reverse,not much will survive,about 2 yrs away,why it's not in news,nothing can be done,and the powers to be have known this,ypou can speculate all you want but the truth is always the truth

I did add it to the thread top of this page 2. It tells clearly why it was done. I would think other places had to adjust but they probably don't generally publicize it. Do you think the magnetic field is aok?




Earth's north magnetic pole is so out of whack that scientists need to update the global magnetic-field model they released only four years ago. Could that be a sign that the magnetic pole will flip soon?




The magnetic pole is moving erratically out of the Canadian Arctic and toward Siberia so unpredictably that it took scientists by surprise. That 2015 update was supposed to remain valid until 2020, Arnaud Chulliat, a geomagnetist at the University of Colorado Boulder and the National Oceanic and Atmospheric Administration's (NOAA) National Centers for Environmental Information, told Nature.

mag·ne·to·sphere

noun
the region surrounding the earth or another astronomical body in which its magnetic field is the predominant effective magnetic field.
For those who don't know, it is our shield



The solar wind drags out the night-side magnetosphere to possibly 1000 times Earth's radius; its exact length is not known. This extension of the magnetosphere is known as the Magnetotail. The outer boundary of Earth's confined geomagnetic field is called the Magnetopause. The Earth's magnetosphere is a highly dynamic structure that responds dramatically to solar variations.

Earth's Magnetic Field Is Weakening 10 Times Faster Now. ... Earth's magnetic field, which protects the planet from huge blasts of deadly solar radiation, has been weakening over the past six months, according to data collected by a European Space Agency (ESA) satellite array called Swarm.Jul 8, 2014

http s://www.sciencealert.com/something-mysterious-under-southern-africa-dramatically-weakening-earth-s-magnetic-field-south-atlantic-anomaly



The region that concerns scientists the most at the moment is called the South Atlantic Anomaly – a huge expanse of the field stretching from Chile to Zimbabwe. The field is so weak within the anomaly that it's hazardous for Earth's satellites to enter it, because the additional radiation it's letting through could disrupt their electronics.

Geologists Joke About 'Sea Monster' After Mysterious 30-Minute Rumble Emanates from Waters Near Madagascar



That day, seismographs all over the world registered a very low-frequency tremor, a strange grumble that lasted for around 30 minutes. One segment of the signal also featured several high-frequency blips, each separated by roughly a minute of time, a bit like a regular, ticking clock. Stephen Hicks, a seismologist at the University of Southampton, highlighted the phenomenon in a November 12 tweet. “Something biggggg, yet strangely slow, sent seismic rumblings around the surface of much of the planet yesterday,” he wrote. Today, that succinct summary still holds, even as discussion of the event continues between geoscientists of all kinds over on Twitter.

MORE Earth's Magnetic Field Can Reverse Poles Ridiculously Quickly, Study Suggests Solar radiation constantly bombards Earth, and Earth’s magnetic field repels it. According to a new study, our planet’s protective shield might weaken far more quickly and unpredictably than scientists previously thought. Credit: NASA / Marshall Space Flight Center Like the invisible force shield around the Death Star, Earth's magnetic field surrounds and protects our planet from the hottest, most statically charged particles the sun can throw our way.



This shield — the natural product of molten iron swirling around the planet's core — has had our backs for billions of years, and prevented Earth from becoming an irradiated, electrified wasteland. Every now and then, though, that shield lets down its guard. A few times every million years or so, Earth's magnetic field reverses polarity. Imagine a giant bar magnet inside our planet got flipped upside down; iron molecules in Earth's outer core would switch direction, the magnetic North Pole would become the magnetic South Pole, and the invisible currents of energy that make up our planet's magnetic armor would tangle and break, potentially reducing the shield's protective strength by up to 90 percent, previous studied have suggested. [6 Visions of Earth's Core] Luckily, full reversals are uncommon and unfold slowly over thousands of years. (The last full reversal occurred about 780,000 years ago.)

But according to a new study published Monday (Aug. 20) in the journal Proceedings of the National Academy of Sciences, partial or temporary shifts in Earth's magnetic poles can occur much, much faster than was previously thought possible — potentially, within a single human lifetime. In the new study, an international team of scientists analyzed 16,000 years of geomagnetic history coded into the atoms of an ancient stalagmite in China.

This story written in stone told them that once, about 98,000 years ago, the planet's magnetic field suddenly flipped polarity in as little as 100 years — roughly 30 times faster than the generally expected rate, and 10 times faster than what was thought to be the fastest rate possible.
