The highest risk

[Brian]

One risk that is not widely publicised is Polarity Reversal. This the phenomenon where either the magnetic poles reverse or there is a global shift and the geographic poles reverse - not as cranky as you may think - it has happened several times in the past, the last being about 3.5 million years ago.

In the case of the geographic reversal all life on earth is likely to end, with polarity reversal massive disruption can be expected, think of all the equipment our life is built around that uses the magnetic poles in it's functionality.
The experts say the next polarity reversal is statistically overdue and the 2004 category 9 earthquake in Sumatra nearly provoked a total geographic polar end-swap. The main reason seems to be that the earth is massively unbalanced and magma eruptions continue to add to this.

This is a threat that we can do nothing to avert or mitigate so keep the masses quiet by not talking about it seems to the policy.
