Snipped most of the stuff I didn't agree with.

Is the Atmosphere chaotic?

No. Not unless you count the organised fractals that the theorists so
desperately need in their supercomputing and of which I know nothing.

If it were truly chaotic it would once in a short while (maybe two or
three times an year) go over the line of survivability in certain
places.

But we see that despite conditions at the end of this spell indicating
it does, there are plenty of survivors in the US mid-west and in the
Tibetan Chinese border.

Furthermore most of the regulars on here seem to accept that there is
a fair argument for forecasting events in it. This despite none of
them besides me having a clue what causes it.
