Submission + - Magnetic Field of Earth Weakening a Sign Poles Are Flipping (guardianlv.com)
Trachman writes: The magnetic field of Earth is weakening more rapidly than many scientists thought it would, a sign that Earth’s magnetic poles might flip within a few hundred years as opposed to thousands of years. Data collected from Swarm, the collective name for three European Space Agency (ESA) satellites, confirms that Earth’s magnetic field is weakening, something which has led to many past switches in Earth’s magnetic poles.Deep ocean core studies have confirmed, according to NASA, that the Earth’s magnetic poles reverse on a relatively frequent basis. They usually switch anywhere from 200,000 to 300,000 years. As it has been 700,000 years or so since a flip has taken place, Earth is overdue for one. The weakening magnetic field might be a sign that the switch will occur sooner, rather than later. Scientists, according to a report by LiveScience, had thought that Earth’s magnetic field was weakening by about five percent every hundred years. At that rate, they calculated that a flip in the Earth’s magnetic fields would not happen for around another 2,000 years. However, the new data from Swarm indicates that Earth’s magnetic field is actually currently weakening at a rate of five percent every decade instead of century. That rate is 10 times faster than the scientists had allowed for in their calculations about when the next flip would happen. That being said, we know that the Earth's magnetic field is primary protecting shield from cosmic particles and, consequently, is a primary factor to the Earth's temperature.
