Polar Storm (also known as Pole Reversal) is a 2009 American-Canadian made-for-television science fiction-disaster-thriller film that was written and directed by Paul Ziller and was aired on the Sci-Fi Channel on March 28, 2009.
In the early 20th century, geologists such as Bernard Brunhes first noticed that some volcanic rocks were magnetized opposite to the direction of the local Earth's field. . The first systematic evidence for and time-scale estimate of the magnetic reversals were made by Motonori Matuyama in the late 1920s; he observed that rocks with reversed fields were all of early Pleistocene age or old
During the transition, Earth's magnetic field declined to a minimum of 5% of its current strength, and was at about 25% of its current strength when fully reversed. This reduction in geomagnetic field strength resulted in more cosmic rays reaching the Earth , causing greater production of the cosmogenic isotopes beryllium-10 and carbon-14 , a ...
This could weaken Earth's protective magnetic field by up to 90% during a polar flip. Earth's magnetic field is what shields us from harmful space radiation which can damage cells, cause cancer ...
The magnetic 'weak point' over the ocean has existed for up to 11 million years, according to researchers. South Atlantic anomaly sheds light on whether Earth’s magnetic poles could flip Skip to ...
During a polar flip, animals that migrate using the magnetic field to find their way, such as whales, butterflies, sea turtles and many species of migratory birds, could be affected.
The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
Could the poles flip for the first time in 700,000 years?
