Solar Flares
Last week, the sun emitted the largest solar flare in four years, and scientists have warned
that Earth should ready itself for a concentrated electromagnetic storm which,
at worst, could be the worldwide equivalent of Hurricane Katrina and cost $2
trillion. Our sun’s troubles are causing global warming on the Earth, Mars, and
other planets.

Additional preparedness for what is also referred to as space weather was strongly urged at the yearly conference of the American Association for the Advancement of Science in Washington. Sir
John Beddington, Britain’s chief scientist, said, “The issue had to be taken seriously, as the sun was emerging from a dormant period and vulnerability had increased.” Jane Lubchenco, says, “Predict and prepare because much more of our technology is vulnerable than it was ten years ago.” A solar storm begins with the eruption of incredibly hot gas out of the sun at speed of as much as five
million miles per hour. Electrically charged particles impact Earth’s atmosphere between twenty and thirty hours later, resulting in electromagnetic upset.

The solar storm of last week caused some radio problems and mild
disruption to civil aviation because flights were routed away from Polar
Regions. The most extreme solar storm ever took place in 1859 and ruined a vast
extent of the planet’s recently-installed telegraph network. A storm of that
magnitude today could wreak havoc with electricity distribution, communications
and information systems, and cost $2 trillion to repair.
