As for how much greenhouse effect is "just right," that is entirely

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.
