The run-away greenhouse is impossible
This wasn't supposed to go to soc.men actually.
My point (I didn't quite finish) was that there can be no such
thing as a true 'run-away greenhouse', that there can be no
abrupt tipping point but only a gradual change. It is
nonetheless irreversible, though.
Also, this has no effect on projections of man-made global
warming, as it can't occur unless solar input is considerably
higher than today.
