[time-nuts] The strange case of solar flares and radioactive elements

[Chris Albertson]

The earth has several feedback systems, some positive and some
negative and they each run on different time scales.   One simple
example is that if it's colder it snows more.  Snow covered ground
reflects sunlight back to space and make the earth even colder.  This
is positive feedback.   But if it is cold plants grow slower and suck
up less carbon which heats the air.    Solar flux only has to move a
tiny bit then get amplified by some positive feedback.  So an effect
is caused by a change that on the surface loks to small to account for
what we see.    Feedback is hard to model and there are many
interacting feedback systems.

Other systems are harder to explain like the gulf stream and the way
it transports heat. This and things like it are powered by solar heat
but to much of it or to little and they shut down or reverse.

And then  now we have man made effects which work on a very short time
scale, so short it has never happened before and so we can't predict
the result.  The fear is that it might trigger a positive feedback.

Positive feedback and unstable systems are easy to see in real life.
Place a book on end.  Now push it about 1/2 inch with your finger
until it falls.   While the cause of the motion was your finger. but
you only pushed it 1/2 inch yet it move 6 or 8 inches.  You only
triggerd and event where the booked moved from one stable state to a
second stable state.   the book is a simple system but the entire
earth is to big to understand and simple models have limited use.
