"Powerful Solar Storm Could Shut Down U.S. for Months
Friday , January 09, 2009

By Robert Roy Britt

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, the scientists conclude, 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, according to the new study, 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.

'Command and control might be lost'

When the sun is in the active phase of its 11-year cycle, it can unleash powerful magnetic storms that disable satellites, threaten astronaut safety, and even disrupt communication systems on Earth.

The worst storms can knock out power grids by inducing currents that melt transformers.

Modern power grids are so interconnected that a big space storm — the type expected to occur about once a century — 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, the new report concludes.

Such widespread power outages, though expected to be a rare possibility, 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. Banks might close, and trade with other countries might halt.

"Emergency services would be strained, and command and control might be lost," write the researchers, led by Daniel Baker, director of the Laboratory for Atmospheric and Space Physics at the University of Colorado in Boulder.

"Whether it is terrestrial catastrophes or extreme space weather incidents, the results can be devastating to modern societies that depend in a myriad of ways on advanced technological systems," Baker said in a statement released with the report.

Stormy past

Solar storms have had significant effects in modern time:

— In 1989, the sun unleashed a tempest that knocked out power to all of Quebec, Canada.

— A remarkable 2003 rampage included 10 major solar flares over a two-week period, knocking out two Earth-orbiting satellites and crippling an instrument aboard a Mars orbiter.

"Obviously, the sun is Earth's life blood," said Richard Fisher, director of the Heliophysics division at NASA. "To mitigate possible public safety issues, it is vital that we better understand extreme space weather events caused by the sun's activity."

"Space weather can produce solar storm electromagnetic fields that induce extreme currents in wires, disrupting power lines, causing wide-spread blackouts and affecting communication cables that support the Internet," the report states. "Severe space weather also produces solar energetic particles and the dislocation of the Earth's radiation belts, which can damage satellites used for commercial communications, global positioning and weather forecasting."

Rush to prepare

The race is on for better forecasting abilities, as the next peak in solar activity is expected to come around 2012.

While the sun is in a lull now, activity can flare up at any moment, and severe space weather — how severe, nobody knows — will ramp up a year or two before the peak.

Some scientists expect the next peak to bring more severe events than other recent peaks.

"A catastrophic failure of commercial and government infrastructure in space and on the ground can be mitigated through raising public awareness, improving vulnerable infrastructure and developing advanced forecasting capabilities," the report states. "Without preventive actions or plans, the trend of increased dependency on modern space-weather sensitive assets could make society more vulnerable in the future."

The report was commissioned and funded by NASA. Experts from around the world in industry, government and academia participated. It was released this week.

  1. Aw, heck. I always just thought California would go down in a flash of earthquake. Now, there's asteroids, catastrophic weather, magnetic pole reversal, alien intervention, economic collapse, unemployment, ozone depletion, governmental intrusion/corruption/ineffectivity, war, revolution/rioting, and your general widespread crime, wildfires, pirates, famine, rap music, negative fuel supply, viruses, global warming, global freezing, global flooding, global government, carbon imprint, analog-to-digital conversion, landslides, widespread power outage, housing losses, and my ex-wife - to name a few.

    But, thanks for the heads-up. I'll be sure to put it on the list.

  2. And this could also be NASA trying to prove their worth
    to the new administration by creating panic in the masses
    with the usual cooperation of the biased media. The more
    dread and foreboding you create, the more the sheeple
    will want government to solve their problems with socialism.

  3. Yes I remember the 89 blackout.
    The up side is that it shamed Hydro-Quebec
    into hardening its networks agaisnt EMPs
    making it more resiliant.

    Also probably why when the eastern half of the North American continent blackout a few years ago, we still had power. I seem to recall Texas also had a similar set up.

  4. Entirely off topic but Flea, which part of computers are you? My sister has has ex (likes his fists & control kwim) who's life goal is to be the best hacker ever. He is making her life hell with anything online and has for past few years - loves viruses, keyloggers, and all that other trash. One day he will cross the wrong person but until then, She is at wits end - got any suggestions? He doesn't work so has all the time in the world.
