Climate Change Has Shifted the Location of the North and South Poles http://apocadocs.com/s.pl?1368628489
Researchers at the University of Texas, Austin, report that increased melting of the Greenland ice sheet -- and to a lesser degree, ice loss in other parts of the globe -- helped to shift the North Pole several centimeters east each year since 2005.
"There was a big change," says lead author Jianli Chen, a geophysicist.
From 1982 to 2005, the pole drifted southeast toward northern Labrador, Canada, at a rate of about 2 milliarcseconds --or roughly 6 centimetres -- per year. But in 2005, the pole changed course and began galloping east toward Greenland at a rate of more than 7 milliarcseconds per year....
Chen estimates that data on polar shifts goes back roughly a century, well before the advent of Earth-monitoring satellites. "We don't have a long record of measuring the polar ice sheet," he says. "But for polar motion, we have a long record."
