Some of those attacks may target America’s power plants, hospitals, airports and other pieces of critical infrastructure, multiple cyber experts that track Tehran’s hackers are warning. Iran’s current Western hacking is limited almost entirely to commercial espionage and dissident surveillance, but the country could quickly redirect its efforts in the event of a rupture of the nuclear pact.

"The short answer to this is absolutely. The possibility of an extreme CME causing a very powerful geomagnetic storm is real. There's considerable uncertainty to how frequent such storms are at the level where we worry about huge impacts on the power grid and the resulting impacts that a lack of electricity would have. Is it a one in 50, one in 100, or one in 1,000 year event? We just don't know," Doug Biesecker of the National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center, told Astrowatch.net.

However, as Biesecker said, these are still in the speculative regime of science, with many of the efforts as yet unfunded, and much more that needs to be done, including finding techniques to quantify the magnetic field, before we can hope to use any of it for forecasting the influence on Earth.
