Appearance of the Earth seen from outer space
The Earth has a hot liquid core that produces a magnetic field, in which the field is able to defend our planet against the devastating wind of the Sun.
The magnetic field extends thousands of kilometers
into space and its appeal affects many things, from global communications to
the grid.
However, the magnetic field that has greatly affected
Earth's life has weakened by 15 percent over the last 200 years. Scientists
claim, it is a sign that the Earth's poles will reverse - from the north to
south pole and vice versa.
In a new report, the director of the Laboratory for
Atmospheric and Space Physics at the University of Colorado, Daniel Baker,
claims there are signs of a reversed Earth pole.
Baker said the reversed poles could make some areas of
Earth uninhabitable and also undermine the power grid.
Quoted from the Daily Mail, Thursday (1/2/2018), the
report was written by Alanna Mitchell in his new book The Spinning Magnet: The
Electromagnetic Force that Created the Modern World and Could Destroy It.
"The danger: the particle flow from the
devastating Sun, the cosmic rays of the galaxy, and the ultraviolet B rays
coming from the ozone layer damaged by radiation are all just some of the
invisible forces that could harm or kill living things," Mitchell wrote.
Historically, the magnetic poles of Earth either North
or South will be inverted every 200,000 or 300,000 years. However, the reversal
of the last magnetic field occurred about 780,000 years ago.
Reverse Impact of the Earth Pole
The European Space Agency's Swarm Satellite (ESA) that
monitors the Earth's magnetic field indicates a possible reversal of the
magnetic field. The satellite allows researchers to study structural changes in
the Earth's core, where a magnetic field is generated.
Their observations show that liquid iron and nickel
emit energy from the Earth's core near where the magnetic field is generated.
While scientists are not sure why that happens, they
describe it as a "restless activity" that shows that the magnetic
field is preparing to reverse.
If that happens, we will be exposed to a solar wind
capable of perforating the ozone layer. As a result, the power grid can be
destroyed, the Earth's climate changes radically, and increases the number of
people with cancer from radiation.
In fact, a study in Denmark believes that global
warming is directly related to magnetic fields, rather than carbon dioxide
emissions.
The researchers predict that after the Earth's poles
are reversed, a hundred thousand people will die each year due to rising levels
of space radiation.
"Radiation can be 3 to 5 times larger than the
ozone hole caused by man-made, and then the ozone hole will be bigger and
longer," said Dr Colin Forsyth of Mullard Space Science Laboratory
University College London.
Is that right?
As published by National Geographic, although the
Earth's poles can be reversed, the weakening power of the Earth's magnetic
field varies considerably. According to NASA, there is no indication that the
magnetic field will disappear altogether.
NASA insists it is important to remember that reverse
Earth's magnetic poles take thousands of years, so the process is responsible
for all drastic weather changes and seismic activity.
According to NASA, the only result of a pole shift is
the change in the direction of the poles, so the direction or compass device
must be fixed.
