Surviving a Carrington Event and Similar Disasters

Surviving a Carrington Event and Similar Disasters - Transhumanity.net: "On 1 September 1859 Richard Carrington observed a series of major coronal mass ejections from the sun – massive solar flares, the largest of which it the Earth’s magnetosphere some 18 hours later (normally it takes around 72 hours). The result was massive auroral displays across the world, even close to equatorial latitudes, and disruption of the telegraph system in a number of nations. Analysis of ice cores suggest that flares of this magnitude occur every 500 years or so. If such an event happened now the consequences would be far more serious."
