Coming for 2012: No GPS, No Cable, Maybe No Electricity
8th November 2010
That’s the way it is with these thing, you know. A lot could happen, but almost nothing must happen. Still, his argument was sobering. Basically we are headed toward a peak of sunspot activity in 2012 or so that could well trigger a Coronal Mass Ejection (CME) that could take out half or more of all geosynchronous satellites, not just GPS. No more satellite navigation, no more cable TV.
CME’s come in various sizes and velocities. CME’s aren’t intrinsically aimed at the Earth and could just as easily dissipate into empty space. Many CME’s don’t even make it as far as the Earth. But if conditions are right, CME’s can do a lot of damage. A CME hit Quebec in 1989 causing a nine-hour blackout and $4.3 billion in damages to the Canadian power grid. The mother of all CME’s in 1859 took down every telegraph in the world, causing arcing, fires, and melted wires in the equipment. Imagine what something like that would do to your PC or cellphone!
