This Historic Solar Flare Would Cost Us £1.5tn If It Struck Earth Today

In the worst case scenario, we'd have just a few minutes to prepare.

In 1859, the sun ejected a solar flare so powerful it turned skies purple, green and red. But besides a few frazzled telegraph wires it was a mostly harmless affair.

However, if the Carrington Event struck Earth today, scientists believe it would leave a trail of destruction costing up to $2tn (£1.5tn).

As Buzz60 explains in a captivating new video (see above), a solar flare of comparable force would now knock out satellites and a considerable portion of the power grid. Thousands of pilots would be forced to make urgent landings without GPS.

In the best case scenario, we’d have a day to prepare. In the worst, just a few minutes.
