Magnetic field reversal and the solar minimum may lead to extinction-level event, study suggests

An international team of researchers suggests that low solar activity and the reversal of the magnetic field together may have cataclysmic effects that can spell the end of life. In a study recently published in the journal Science, the researchers detailed how the decline of the archaic Neanderthals and extinction of megafauna may be linked to the solar minimum a long time ago and the Laschamp excursion, a period around 42,000 years ago in which Earth’s magnetic field temporarily flipped.
Re-examining the impact of a magnetic field reversal
Earth’s magnetic field serves as a protective shield against harmful cosmic radiation. But when it flips, it becomes weaker and leaves the planet exposed to higher levels of radiation. This is the scenario for roughly 1,000 years during Laschamp.
Past studies suggest that this event had little impact on the planet. But according to the researchers, that’s possibly because the focus was not on the period during which the poles were actually shifting.
The researchers then performed radiocarbon analyses of the rings of ancient kauri trees in New Zealand to reevaluate the impact of Laschamp. This allowed them to track over time the rise in atmospheric levels of carbon-14 that was produced by increased cosmic radiation. The researchers then compared these carbon levels with numerous geologic records from all over the world to date significant atmospheric changes around the time.
Analysis showed that an array of major environmental changes happened at the same time carbon-14 levels peaked. Some of those changes include a massive growth of the North American ice sheet, a shift in the western Pacific’s tropical rain belts and a drying out in Australia, said Chris Turney, a professor of earth science at the University of New South Wales and one of the study researchers.
Ice core records also suggest that dips in solar activity, known as the grand solar minima, coincided with Laschamp. Such dips can also have significant effects on the planet as the sun becomes unstable during those periods – it can emit solar flares and coronal mass ejections that bring higher levels of radiation to Earth.
The researchers then used a model to see what would happen if solar activity plummeted at the same time as the magnetic field disappeared. The model showed that the combination of these two events might have depleted the ozone layer and triggered climate shifts, electrical storms and widespread auroras.
The team suspects that these environmental changes potentially accelerated the growth of ice sheets and contributed to the extinction of Australian megafauna and the gradual decline of the Neanderthals. They also linked these changes to the increased use of caves as shelter and the emergence of red ocher handprints for cave art and sunscreen.
“It probably would have seemed like the end of days,” Turney said.
That those seemingly random cosmic events 42,000 years ago appear to be connected led the researchers to call this intricate mosaic of a period the “Adams Event.” The name is a tribute to science fiction writer Douglas Adams, who wrote in his book “The Hitchhiker’s Guide to the Galaxy” that the number “42” is the answer to the mysteries of the universe.
What happens if the magnetic field flips now?
Some experts believe that Earth’s magnetic field may flip relatively soon. This protective shield already weakened by around nine percent for the past 170 years, and the presence of the South Atlantic Anomaly – a weak spot in the magnetic field just above South America and the South Atlantic Ocean, which has been growing as of late – is further stoking concerns.
If the magnetic field reverses, satellite networks and power grids will be the most affected. Even now when the magnetic field still mostly stable, solar storms are already damaging satellites, causing power outages and interrupting radio communications. In March 1989, for example, a coronal mass ejection triggered a widespread power failure that cut off electrical supply to over six million people in Canada and across the northeastern U.S. for nine hours.
A magnetic field flip can also affect humans and animals. Increased levels of radiation can potentially increase skin cancer cases while animals like bees, whales and turtles that rely on geomagnetism for navigation might not be able to cope with the reversal.
It’s clear that the reversal of Earth’s magnetic field poses a great threat to humanity. Learn more about potential disaster scenarios during a magnetic field flip and other catastrophic events at Disaster.news.

“Alien bases” may be hiding off the coast of Alaska, researchers say

An organization of civilian volunteers dedicated to the study of
unidentified flying objects (UFOs) has issued a statement based on
decades of studying eyewitness reports. According to Mutual UFO Network,
“alien bases” may be hiding off the coast of Alaska, reports the-sun.com.
Researchers
say the deep waters in this region may hold something surprising. After
analyzing reports from the ship’s crew from 1945, they hypothesized
that alien objects could be lurking underwater, off the coast of the
state.
Alleged sightings of alien spacecraft nearly 80 years ago
have become a key point in research. Members of the organization believe
that UFOs move over water and may have “bases.”
Researchers
allege crew members on a U.S. Army transporter ship sailing past Island
Adak saw a massive UFO sized 150 to 200 feet emerge from the water.
Although these reports are nowhere to be found, UFO enthusiasts believe
the unidentified flying vehicles likely were used to commute to
different supposed alien bases hiding in the deep waters.
As
the “secret reports” of the sailors aren’t available, investigators
have taken it upon themselves to unravel the mystery surrounding the
unidentified flying objects and they believe the ocean has alien bases
that humans aren’t aware of.
Enthusiasts claim that UFOs may be
using “underwater networks” or wormholes as superhighways to travel
between points in the universe. UFO researcher Johnny Enoch added that
such objects could serve as a vehicle for aliens.
There are also
theories that other places on Earth could serve as bases for alien life.
A mountain in Seoul, South Korea is believed to be hiding a UFO,
according to Dr. Steven Greer.
An episode of the series “The
Alaska Triangle” features satellite imagery that claims to show one of
the “alien bases” in the Pacific Ocean off the coast of California.
Meanwhile,
another researcher featured in the program showed markings from the sea
bed that she claimed could have been roadways for aliens.
While
the mysteries of the ocean remain unsolved, researchers continue their
search, trying to unravel the mystery of what may be hiding in the
depths of the waters off the coast of Alaska.

Enormous City-Size Comet Racing Towards Earth Grows ‘Devil Horns’ After Massive Eruption

A volcanic comet the size of a mid-sized US city has
violently exploded for the second time in four months as it continues
racing toward the earth. And following the massive eruption, the cloud
of ice and gas sprouted what looked like a pair of gigantic devil horns.
The city-sized comet, named 12P/Pons-Brooks, is a cryovolcanic — or
cold volcano — comet. It has a solid nucleus, with an estimated diameter
of 18.6 miles, and is filled with a mix of ice, dust and gas known as
cryomagma. The nucleus is surrounded by a fuzzy cloud of gas called a
coma, which leaks out of the comet’s interior.
When solar radiation heats the comet’s insides, the pressure builds up
and the comet violently explodes, ejaculating its ice-cold innards into
space through seeping cracks in the nucleus’s shell.
Live Science report:
On Oct. 5, astronomers detected a large outburst from 12P, after the
comet became dozens of times brighter due to the extra light reflecting
from its expanded coma, according to the British Astronomical Association (BAA), which has been closely monitoring the comet
Over the next few days, the comet’s coma expanded further and developed its “peculiar horns,” Spaceweather.com
reported. Some experts joked that the irregular shape of the coma also
makes the comet look like a science fiction spaceship, such as the
Millennium Falcon from Star Wars.
The unusual shape of the comet’s coma is likely due to an irregularity in the shape of 12P’s nucleus, Richard Miles, a BAA astronomer, told Live Science after the comet’s previous eruption.
The outflowing gas is likely being partially obstructed by a notch
sticking out on the nucleus, Miles said. As the gas continues to expand
away from the comet, the irregularity in the coma’s shape becomes more
defined and noticeable, he added.
12P is currently hurtling toward the inner solar system, where it
will be slingshotted around the sun on its highly elliptical 71-year
orbit around our home star — similar to the green comet Nishimura, which
pulled off a near-identical maneuver on Sept. 17.
12P will reach its closest point to Earth on April 21, 2024, when it
may become visible to the naked eye before being catapulted back toward
the outer solar system. It will not return until 2095.
This is the second time 12P has sprouted its horns this year. On July
20, astronomers witnessed the comet blow its top for the first time in
69 years (mainly due to its outbursts being less frequent and harder to
spot during the rest of its orbit). On that occasion, 12P’s coma grew to
around 143,000 miles (230,000 km), which is around 7,000 times wider
than the comet’s nucleus.
It is unclear how large the coma grew during the most recent
eruption, but there are signs the outburst was “twice as intense” as the
previous one, the BAA noted. By now, the coma has likely shrunk back to
near its normal size.
As 12P continues to race toward the sun, there is a high probability
that we will witness several more major eruptions. It is possible that
those eruptions will be even bigger than the most recent one as the
comet soaks up more solar radiation, according to Spaceweather.com.
But 12P is not the only volcanic comet that astronomers are currently
monitoring: 29P/Schwassmann-Wachmann (29P) — the most volatile volcanic
comet in the solar system — has also had several noticeable eruptions
in the last year.
In December 2022, 29P experienced its largest eruption in around 12 years, which sprayed around 1 million tons of cryomagma into space. And in April this year, for the first time ever, scientists accurately predicted one of 29P’s eruptions before it actually happened, thanks to a slight increase in the comet’s brightness in the lead-up to the icy explosion.
