Earth's Magnetic Field Weakens 10 Percent

caryw writes "Interesting story from the AP. 'The strength of the Earth's magnetic field has decreased 10 percent over the past 150 years, raising the remote possibility that it may collapse and later reverse, flipping the planet's poles for the first time in nearly a million years, scientists said Thursday. At that rate of decline, the field could vanish altogether in 1,500 to 2,000 years, said Jeremy Bloxham of Harvard University. Hundreds of years could pass before a flip-flopped field returned to where it was 780,000 years ago. But scientists at a meeting of the American Geophysical Union cautioned that scenario is an unlikely one. "The chances are it will not," Bloxham said. "Reversals are a rare event."'"

    Now, when Magneto is weakest, it is the time for the X-Men to strike and remove the threat of the Brotherhood of Evil Mutants forever!

    Time to panic!

    Didn't you see the movie "The Core?" (It stars the lucious Hillary Swank and shows the devastation that awaits a loss of the magnetosphere. See http://www.imdb.com/title/tt0298814/)

    People with pacemakers will all die! Pigeons will get confused and fly into buildings! Electrical Superstorms will destroy ancient Roman Colosseums!

    I think I saw a documentary on this. It's related to the centre of our planet stopping spinning or something like that, and they need to send some nukes down there to restart it.

    I think the documentary was called 'The Middle', 'The Core', 'The Deep'... something like that.

    If Americans had elected in Al Gore in '00, we'd have the Kyoto Protocol in place and mans affect on the magnetic field would have returned to 1988 levels!

    I mean really, no matter how bad the radiation gets outside, it's not like we're gonna be feeling it. Hey, maybe with all the skin cancer, being pasty white will even be considered a sign of good health, and geeks will reign supreme.

    Nah, wishfull thinking...
