Solar Storms Could Induce SHTF.... Wow. Scary stuff. Wonder what one of these solar storms would do to one's solar setup. I don't know enough about solar energy systems to tell if they'd be at risk as well. Also a good argument for having water stored or a way to get it in the absence of electrical power.... http://www.foxnews.com/story/0,2933,478024,00.html Quote:
Report: Powerful Solar Storm Could Shut Down U.S. for Months Thursday, January 08, 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 major solar storm in 1859 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.

Re: Solar Storms Could Induce SHTF.... No need to wax and wain over it..........a solar storm is like a super volcano. That baby goes off.......you dont have anything to worry about anymore. T

Re: Solar Storms Could Induce SHTF.... it wouldn't affect solar powered systems... the damage is done to magnetically sensitive equipment.

What about the powerlines that send energy back and forth??? T

Re: Solar Storms Could Induce SHTF.... Couldn't this be faked? Simply get all the players in line and shut everything off. "Fortunately, the military and certain systems were protected enough to withstand the storm. Please proceed to the nearest FEMA shelter."

Re: Solar Storms Could Induce SHTF.... What is funny is that the entire system is set up to fail if we have the type of event that happened only 150 years ago. It's not like it will never happen again.

Given how many people would have to keep quiet about it, no.

Re: Solar Storms Could Induce SHTF.... Just set off an EMP and blame it on a solar storm. I do not think a solar storm would affect cars the way and EMP would but they would just say it was due to a solar storm bigger than any other in history.

Re: Solar Storms Could Induce SHTF.... Here is all you need to know about that article: "A new study from the National Academy of Sciences " From that point on is all Bravo Sierra.

Re: Solar Storms Could Induce SHTF.... Another little problem A number of recent studies (see McComas et al., 2008, and references therein) have concluded that the solar wind observed in Ulysses' third orbit is about 25 percent less powerful than that measured during the spacecraft's first orbit. (Both of these orbits corresponded to periods of minimum solar activity.) While the wind speed is almost the same during both orbits, the density and pressure measured during the third orbit are significantly lower. "The heliosphere has been shrinking" The marked long-term trend to lower dynamic pressures implies that the heliosphere has been shrinking and as a consequence the distance to the heliopause is reduced. Since the heliopause acts as a shield for our solar system, warding off a significant portion of the cosmic rays outside the Galaxy, a reduction in size and strength could mean an increase in the number of Galactic cosmic rays which enter the inner part of the solar system. http://sci.esa.int/science-e/www/obj...objectid=43458

My thinking too. Actual solar conditions that cause such storms are at their lowest level right now in 50 years. This is the time least like so see solar storms (and perhaps more volcanic activity, but I digress). Most solar flares are the result of 'snaped' secondary solar currents that cause sunspots. Sept.08: NASA: Solar Wind Loses Power, Hits 50-year Low Dec.29: Where have all the sunspots gone? So Fox is either as wrong as they can be, or they are pimping a mime for controller's purposes.
