Worst case EMP scenario? Half in U.S. dead

Worst case EMP scenario? Half in U.S. dead: "NASA estimates that a direct hit to Earth from one of these enormous flares would have a catastrophic impact on the nation’s critical infrastructures over a very wide geographical area. In the first year alone, NASA estimates, such a disaster could cost just the U.S. upwards of $2 trillion. It also would take from four to 10 years to recover – if that even would be possible – and affect the lives of some 160 million people, threatening starvation and death."
