NASA: Global Warming Is Now Changing How Earth Wobbles (go.com)

An anonymous reader writes: A new study from NASA finds global warming is shifting the way the Earth wobbles on its polar axis. Melting ice sheets are changing the distribution of weight on Earth, which has caused both the North Pole and the wobble, called polar motion, to change course. Since 1899, scientists and navigators have been accurately measuring the true pole and polar motion and for almost the entire 20th century they migrated a bit toward Canada. That migration has changed with this century -- now they're moving toward England, said study lead author Surendra Adhikari at NASA's Jet Propulsion Lab. "The recent shift from the 20th-century direction is very dramatic," Adhikari said. NASA scientist and the study's co-author Eirk Ivins said, Greenland has lost on average more than 600 trillion pounds of ice a year since 2003 and that affects the way the Earth wobbles in a manner similar to a figure skater lifting one leg while spinning.

Maybe it'll make all those denialist idiots sticking their heads in the sand, even more dizzy than they were.

Nah. They'll just say that man doesn't understand everything, God is doing it and besides those scientists are all biased liburs cuz they're taking govt money.... *sigh* yes I actually have heard this argument
