I would have thought that any "balance" would have been established
before we came along. Note your next comment. "Balance", I agree, is
not a term that should be used in this discussion.

That's not a helpful observation. On a geologic time scale, human
existance is a just a blip. I don't think the next 4 or 5 generations
will think it so small a deal, however.

Yes, most researchers seem to agree that it will.

Of course it will. The question isn't whether or not, it's how much.
The problem with our greenhouse gas emissions is that it is very
likely to increase the *rate* of change to our climate quite
dramatically.

A change in global temperatures over the next 100 years that would
normally be seen over 10,000 years is not going to be insignificant.
Nor a "good thing".

What goals could they be?

The only studies I've read that don't support the findings of the UN
research into climate change have been published by people funded by
vested interests.

I don't believe that you're right at all about this. I believe that
global warning has been subject to a great deal of scrutiny.
Industries that stand to lose money short term will argue against it,
both ways: Fossil fuel companies argue it's insignificant, insurance
companies argue that it's quite significant.

As it should.

As opposed to funding on drug research? As opposed to ozone research?
Please.

This is fine for people in the US. If you had been born and raised on
the Solomons, though, you might be annoyed to find that the world
doesn't care if your entire homeland is inundated. This is a very
simplistic argument - I'll address it more further down.

If they're right, we'll be moving almost 50% of the world's population
inland.
And it seems they are right: In the 130 years that temperatures have
been recorded, 1980, 1981, 1983, 1987, 1988, 1990, were six of the
seven warmest years recorded. The trend was interrupted by the
eruption of Mount Pinatubo in 1991 which cooled temperatures around
the world for several years due to the amount of dust emitted into the
atmosphere. In l995 the warming trend was reestablished, with 1995
being the warmest year yet, coming in at 59.7F.
You'll probably right that off as a "blip", too.

I don't understand what you mean by "rearranging" the lives of
millions of Americans? Surely encouraging efficiency can only be a
good thing?

What on earth brings you to this conclusion?

And I think you have dramatically understated the possible problems.
The costs of climate change are already being seen, I believe, and
will continue to grow. You talk about a couple of million people
relocating like it's a small thing. How much to relocate NYC, I
wonder? Relocation is going to be a long way away, though, as you've
said. Besides, some places could be protected by sea walls etc.
However, rising sea levels are only one effect of faster climate
change. A more dramatic change is the increasing number of natural
disasters: Storms, fires, droughts, etc. Here in Australia, we've
been suffering the longest doughts on record - in some areas, over 6
years long.
So you may move everyone to Kansas, but what are they going to eat?
According to the Reinsurance Association of America, nearly 50% of the
insured losses from natural catastrophes during the past forty years
have been incurred since 1990.
Other issues include: Increased rates of insect born diseases, faster
rates of species extinction, increased warfare over dwindling food and
water supplies in some regions, etc. etc.
You talk about the effects on Americans to change the way they live.
I suggest you think more globally, and think about the possibility
that no major change needs to occur to any individual for there to be
major drops in greenhouse gas emissions. Is anyone put out by
clicking on a lower wattage light globe? Is anyone harmed by living
in a house that requires dramatically less cooling or heating, due to
good design? Does anyone really care what kind of engine gets them to
work in the morning? Is anyone hurt by the job opportunities that are
created by getting cleaner, more efficient technology up and running a
little bit quicker. After all, you have acknowledged the move from
fossil fuels is a matter of "when", not "if", so why not now? Even
the big oil companies won't lose out: One of the biggest suppliers in
Australia of photo-electric cells is BP Solar. Efficiency isn't a bad
thing, you know. Nor is change.
