A new study from the National Academy of Sciences outlines grim possibilities on Earth for a worst-case scenario solar storm. Damage to power grids and other communications systems could be catastrophic ... with effects leading to a potential loss of governmental control of the situation. The prediction is based in part on a major solar storm in 1859 that caused telegraph wires to short out in the United States and Europe, igniting widespread fires. It was perhaps the worst in the past 200 years ... and with the advent of modern power grids and satellites, much more is at risk. "A contemporary repetition of the [1859] event would cause significantly more extensive (and possibly catastrophic) social and economic disruptions," the researchers conclude. Modern power grids are so interconnected that a big space storm ... could cause a cascade of failures that would sweep across the United States, cutting power to 130 million people or more in this country alone. Such widespread power outages ... would affect other vital systems. "Impacts would be felt on interdependent infrastructures with, for example, potable water distribution affected within several hours; perishable foods and medications lost in 12-24 hours; immediate or eventual loss of heating/air conditioning, sewage disposal, phone service, transportation, fuel resupply and so on," the report states. Outages could take months to fix, the researchers say.
