Solar 'super-storms' could be catastrophic

A particularly violent solar storm could one day have disasterous consequences for the modern world.
While huge solar storms don't tend to hit us very often, their potential to disrupt power and communications systems across the globe has been an ongoing concern.

The last time this happened was 150 years ago when a particularly damaging storm, known as the Carrington Event after the astronomer who observed the preceding solar flare, produced a coronal mass ejection with the equivalent energy of 10 billion Hiroshima bombs.

At the time the world's electronic infrastructure consisted of little more than telegraph lines, but if it were to happen again today in a world dominated by wireless communications and electronic devices the effects could prove to be catastrophic.

"Without power, people would struggle to fuel their cars at petrol stations, get money from cash dispensers or pay online," said Ashley Dale from the University of Bristol. "Water and sewage systems would be affected too, meaning that health epidemics in urbanized areas would quickly take a grip, with diseases we thought we had left behind centuries ago soon returning."

According to scientists these solar super-storms occur around once every 150 years meaning that one is now worryingly overdue. Some predict that the chance of another storm hitting us within the next decade could be as high as 12%.

I will eagerly anticipate the spectacular CME coming soon. A major EMP could wipe out all electricity, telecommunications and fry electrical devices. No power for lights or to run your computer or to pump your water. Your car wouldn't run because its computer was toast and even if you own a 1970s vintage car, your couldn't get gas for it because the pumps couldn't get power. No way for farmers to get fuel for their equipment, or to get crops to market if they did. And no way to process those crops into food. And no way to get them to you. No water to drink, no food to eat and no way to get awa... [More]

Unless shielded from the EM shockwave in a faraday cage or some other means you can kiss all that technology goodbye. Did you ever read about the 19th century's storm that melted telegraph wires?

Read up on the Carrington Event of 1859, and how a similar event would affect today's over-reliance on technology
