The sun's activity, which follows 11-year cycles, will experience its next peak in 2013. A solar storm of the strongest variety could cause 20 times more economic damage than Hurricane Katrina , said a 2008 National Academy of Sciences report on space weather.
Though the odds of a such a storm are relatively small, such an occurrence could create severe weather in the sun's outer atmosphere, knocking out much of the country's power grid, incapacitating navigational systems and jeopardizing spacecraft, scientists say.
More than a million people could go without power, the distribution of drinkable water could be disrupted and transportation, communication and banking systems could be upset, the report said.
To prepare for the activity, scientists from NASA, the National Oceanic and Atmospheric Administration, the National Science Foundation and other agencies met earlier this week for discussions at a forum in Washington, D.C.
"The sun is waking up from a deep slumber, and in the next few years we expect to see much higher levels of solar activity. At the same time, our technological society has developed an unprecedented sensitivity to solar storms. The intersection of these two issues is what we're getting together to discuss," Richard Fisher, head of NASA's Heliophysics Division, said in a recent NASA report ahead of the meeting.
Scientists warn that despite the long odds of a severe solar storm, more needs to be done to prepare for the potential danger. And they emphasize that humanity has observed extreme consequences from solar activity before.
