Earth's magnetic field is constantly changing and is about 200 or 300 thousand. flips the poles - north becomes south and vice versa. Currently, humanity is on the brink of change, and scientists warn that the changes could be taken over the next century. This will inevitably change our lives.
According to 2004. have been recorded with the National Science Foundation for research up to now, it was thought that the pole exchanges occur during the 7 thousand. years, but the last few years, another team of researchers carried out new research and found that the pole exchange can happen much more quickly.
The new study, published in Geophysical Journal International, a joint team of scientists from Europe and the United States declares that the last pole exchange lasted a hundred years, writes gizmodo.com.
As the researchers were able to conduct a study examining the changes that took place in front of hundreds of thousands of years? They did investigating over 10 thousand. Leading the volcanic ash layers found near Rome. According to the research team, the magnetic field lines are "hard-frozen" and their ashes can reliably determine when these exchanges took place and how long it took.
"We do not know whether the other pole exchange will take place as soon as the latter, but we can not deny that it will not be fast," - said one of the study authors Paul Renne'as.
The end of the map shows how, before the onset of approximately 789 thousand. the North Pole, Antarctica wandering about a few thousand years ago, as long as 786 thousand. years come around to where it is today - in Antarctica.
That the Earth's magnetic field is changing scientists have known for some time. Also, scientists have known that over the past two hundred years, the North Pole has moved about 600 miles. And the European Space Agency's reports, we know that in certain areas of the Earth's magnetic field is weakening.
All of these changes are gradually transforming our daily lives: for example, airports have been forced to change runways labeling systems in the future, if it turns out that the poles are indeed changing, the impact will be even greater.
For example, reduced magnetic field means that people are more exposed to the sun's dangerous rays that cause cancer, and cancer incidence is likely to increase. In addition, you may experience and large infrastructure problems with the electricity network and other sensitive systems.
However, the short people to be living in such a huge change witnessed a very rare phenomenon. We can see what other types of people may have to wait at least a few hundred thousand years.
