Growing vulnerability to geomagnetic storms

Our greater reliance on electricity, national grids and technology leaves us more and ever vulnerable to geomagnetic storms. Such storms have occurred irregularly in documented history back to 567 BC.

An article in reports that researchers in Asia have looked back at the history of the so-called Carrington Event – a gigantic geomagnetic storm that hit in 1859. A 2013 study from Lloyd’s of London estimated a $2.6 trillion cost for North America if a Carrington-level storm happened now, and predicted, “a Carrington-level, extreme geomagnetic storm is almost inevitable in the future.”
