As for how much greenhouse effect is "just right," that is entirely
subjective.
I'm sure the dinosaurs were quite happy with the levvels of greenhouse
gasses present during their existence...as were teh whooly mammoths
during theirs. The earth changes. It always has, it always will and the
living beings on the earth either adapt or die. The onl;y difference
between us and the dinasaurs or mammoths is that we possess the hubris
to think we are capable of changing the earth to any but but slight
variances. I'm not saying that we should not be careful and guard what
we do for the preservationof our own species, but the idea that we are
responsible for global climitazation alone? The facts are that this
earth is cyclical and that it is presently entering a new cycle. Yes,
clean up the mess so we don't have to breathe it, eat it, or live in
swill but realize that the warming and cooling of the earth is beyond
our control short of a nuclear war.


The dinosaurs lasted for 100M years, likely until a catastrophic event
wiped them out over a very short period of time. The changes that are
being discussed have happened over a period of less than 200 years,
almost all of it is due to the industrial revolution. There's no doubt
that the earth's climate varies a lot. There's also no doubt that the
recent changes have been dramatic. If we don't address our own pollution,
we won't have to wait very long.


ANd maybe that's a good thing...


You have a point, but I don't want to be miserable in the waiting room.
