Shift in magnetic pole.
by Sun Sentinel:
Magnetic north, the point at the top of the Earth that determines compass headings, is shifting its position at a rate of about 40 miles per year. In geologic terms, it’s racing from the Arctic Ocean near Canada toward Russia.
As a result, everyone who uses a compass, even as a backup to modern GPS navigation systems, needs to be aware of the shift, make adjustments or obtain updated charts to ensure they get where they intend to go, authorities say. That includes pilots, boaters and even hikers.
Although the magnetic shift has little impact on the average person and presents no danger to the Earth overall, it is costing the aviation and marine industries millions of dollars to upgrade navigational systems and charts.
The Earth’s core of hot liquid iron is constantly moving. That motion, combined with forces such as the Earth’s rotation, dictate the position of magnetic north, not to be confused with geographic north, or the North Pole.
Over the past century, the shift has been increasing in speed. It went from creeping as slow as nine miles per year in the early 1900s to more than 35 miles per year in the 2000s. However, that acceleration also is part of natural cycle, Love said.
Humans aren’t the only ones affected by magnetic north. Birds that fly south for the winter and some sea turtles that migrate from Africa to South America must learn to adjust their senses so they end up migrating in the right direction, Love said.
Magnetic shifts can be cause for alarm since they are linked to an icrease in global super storms (Pakistan floods have been linked to global warming). Magnetic poles shield earth from cancer causing radiation and it seems the downward shift of the magnetic field has sped up over the past 50 years. This magnetic shift is natural BUT the current speed of the shift has scientists wondering if their are other hidden factors behind the rapid decline.Unfortunately, there are limited human studies explaining (or even analyzing) why the speed has doubled in the last 50 years therefore I am unable to provide more information for you all regarding the subject. I will keep fellow martians updated on the status of the shifts .
