LIFE Will North Pole Become the South Pole?

Will North Pole Become the South Pole?

The News

Scientists have said that the Earth's magnetic fields are now due for a change. This is known as a Geomagnetic Reversal or Polar Reversal. In the last 20 million years, the Earth has had polar reversals after every 200,000 to 300,000 years. The last such reversal occurred about 78,000 years ago. It is nicely depicted that how life we know will change, in a new book 'The Snipping Magnet'authored by Alanna Mitchell, a journalist and author based in Toronto , Canada.

Understand
behind the news


A Geomagnetic Reversal or Polar Reversal is a phenomenon in which the planet's magnetic north and magnetic south is interchanged. According to scientists, before such a successful shift takes place, there are few unsuccessful attempts, that happen. Around 40,000 years ago, the earth's poles made such an unsuccessful attempt at a polar reversal. And now the Earth's magnetic poles are preparing to flip once again. The magnetic fields of Earth protect it from the solar and cosmic rays. So, when there is a reversal, and the poles flip, this protective shield could reduce majorly. The process of polar switching can go on for centuries, and throughout this process, the planet would be getting more cosmic and solar rays.

beyond the news


Did you know, that if the radiations reach Earth, they could cause extinction of species, and make some places in our planet uninhabitable? A weak magnetic field would also damage the satellites. But, don't worry. This does not mean that future would be really bad. Since, we can predict this possibility, we will be able to find out ways to survive and sort these issues too. Scientists are looking out to find solutions, and hopefully they will come out with some solutions soon.
