Well, ignoring the cutsie bs about spotted owls and all, keep in mind

CO2, atmospheric levels now exceed 400 parts per million (ppm).
Paleological records show that every time CO2 levels have exceeded 300
ppm there has been an ice age. Every time, without exception.
The same records show that there have been a series of ice ages over
the past 5 million years, naturally occurring every 100,000 years,
with about 90,000 years of glaciation followed by about 12,000 years
of interglacial climate.
The last ice age ended about 12,000 years ago. I am more inclined to
believe what has happened in the past without exception, than the
incredibly unreliable speculation about what will happen into the
future 100 to 1000 years from now. Are planet is cyclical, what goes
around comes around.
Does this mean we will be heading into an ice age anytime soon,
certainly not. One thing I do know for sure is that the sky is not
falling, Chicken Little.
What is interesting is that according to those same ice cores, instead
of peak and precipitate drop in temperature, there had been a peak
and hold this time. And that hold goes back far more than the few
hundred years that the advocates of the industrial-emission theory are
claiming. So it seems likely that _something_ has changed that has
nothing to do with human activity, or if the something is human
activity it's not industrial CO2 emissions.
Whatever we're doing, if humans _are_ doing it we bloody well better
keep it up until we figure out the consequences of _stopping_.
That's the big problem I have with the "we must fix this
******NOW******" argument--we don't have any reason other than a bunch
of opinions to believe that we won't be jumping out of the frying pan
into the fire.
At some point, the world is going to warm, whether humans do it or
not. The natural state over tens of millions of years has been warm
enough that there were no ice caps. The only reason that humans think
that the current state is "normal" is that we've never experienced in
our few tens of thousands of years of existence anything _different_.
If we see it as a bad thing then at some point we're going to have to
interfere with natural processes in order to _stop_ it.
The big question, that nobody seems to want to address, is "is what we
are seeing the natural end of the ice ages".
