'Black swan' predictions for 2013 include solar storm
U.S. Global Trends report does not include Mayan calendar worries, but a 'solar maximum' or cyberwar could cause problems
Computerworld - In 1859, there was a solar event so extreme that witnesses reported seeing brilliant lights, electrical flashes, red glows and other aurora events, even in the South. It was the lead story on Sept. 3 of that year in the Memphis Daily, according to a copy preserved by the Library of Congress.
"On Thursday night last, about 12 o'clock, the heavens were suddenly lit up as with a half dozen moons. The cry of fire was heard on every street, and the fire bells of the city were rung, arousing our whole population. When the truth revealed itself it appears that Old Nature had only lit up its own chandelier in order, as it might be, to reveal the wickedness going on at the dead hour of night," the newspaper reported.
It was more than a light show. Telegraph systems malfunctioned, sparked and scrambled messages. The possibility that these events were connected to activity on the Sun was suggested by British astronomer, Richard Carrington, who observed intensely bright and white light from a group of sunspots.
What stirred Memphis occurred during a solar maximum, a period of increased solar activity that is marked by numerous sunspots.
If you are making a list of tech predictions for next year, as this story does, it may be a good idea to put the solar maximum on this list. The next one is expected in 2013, says NASA.
Solar maximums are natural events occurring about every 11 years, and they have caused severe disruptions to electrical systems. An event similar to the one in 1859 could be calamity.
A new U.S. government report forecasting global trends through 2030 includes a short section called "black swans," which are difficult to predict but potentially disruptive events, such as a solar storm.
"Solar geomagnetic storms could knock out satellites, the electric grid, and many sensitive electronic devices," said this report, Global Trends 2030. "The recurrence intervals of crippling solar geomagnetic storms, which are less than a century, now pose a substantial threat because of the world's dependence on electricity."
The idea that solar storms can deliver serious disruption at intervals of once every hundred years is based on limited historical data. "That's as good as an estimate as anyone can give," said W. Jeffrey Hughes, director of Boston University's Center for Integrated Space Weather Modeling and a professor of astronomy.
The 1859 solar storm is now called the Carrington Event, possibly the strongest on record. But there was another, the "great storm" in May 16, 1921, which disrupted communications and power. More recently, a solar storm in 1989 was responsible for a power outage in Canada affecting 6 million. Solar storms have hurt satellites, and disrupted an FAA GPS system.
