    Space weather and GPS effect
    From: Randall Morrow
    Date: 2014 Mar 19, 14:53 -0700

    We missed a big solar flare in 2012 and according to a recent Fox News article, had it hit it would take years to recover:

    "The cost of an extreme space weather event, if it hits Earth, could reach trillions of dollars with a potential recovery time of 4-10 years," professor at China's State Key Laboratory of Space Weather Ying D. Liu warned in a press release. "Therefore, it is paramount to the security and economic interest of the modern society to understand solar superstorms."

    This is likely a "when", not an "if" scenario. They say the last "big one" was about 1859 and now of course, the effects would be much worse.
