B An Ancient Solar Storm 9200 years ago is Cause for Concern

TL;DR

An ancient solar storm occurred 9200 years ago during a solar minimum wreaking havoc on the Earth. We are not prepared when it happens again.

I think that even a simple repetition of the Carrington event will be disastrous. We do not have to look at an event 9,000 years ago. 160 years are sufficient.

A Carrington type event nearly missed us in 2012:

And yes, this kind solar storm hitting the Earth in this technological age would be catastrophic.

I wonder if there are other types of catastrophic events that don't leave a noticeable record.

It seems every kind of event where the Earth survives shows a scar of some sort that scientists can discover. Only a catastropic event of a similar type occurring over another might destroy any prior evidence but we would never know because there’s no evidence to know.

Theres an interesting book on catastropic events called The Doomsday Book where several different types of events are described and their aftereffects are explained in greater detail.
