Whether or not AGW is true, to what extent it is true, or whether we can
"significantly" affect the future global warming, there does appear to
be global climate change in the offing.
I was particularly interested in an article I read about the melting of
the Himilayan glaciers (the "third pole"). Unbeknownst to me, the
Himilayans are the source of the bulk of all water to India, South East
Asia, and China, where a large percentage of the world inhabits.
Now, I can't claim to understand why global warming, resulting in an
increase of liquid water, would result in less available water, but
apparently this is what many believe will happen, and there is evidence
that it is already happening. Presuming a conservation of water, it is
either in ice, liquid, or vapor. If less is contained in ice, more must
be contained in the other two phases. So I can't clearly understand
this, save that water distribution will change.
Warming of the globe is, itself not a problem. It's the changes and
shifts in vital materials, e.g., water, that matters. My point is to
the energy crisis (in particular the distribution of fossil fuels), we
might add a coming water crisis. Both will, perhaps in our life time,
(though I doubt it) destablize the world economies. In the past, this
has led to wars. If the world population could redistribute itself
peaceably, this might not be a problem, although, as always, there's a
time scale problem.
It seems to me that water shortage is even more destabilizing than
energy fuels. Energy fuels can be transported, albeit at some
significant cost, water cannot. The only way to solve the water
distribution problem is to move people, depopulating one region and
increasing the population of another. In the past (witness the
populating of America, or the Israelites into the Promised Land), this
has resulted in armed conflicts.
What this entails is that immigration may become a signifcant moral
and international issue.

I think this is exactly right. The real smoking gun in all of this, as I have said before, is that no one admits the globe has been much warmer before and we all survived. Whether humans are contributing to it or not is a minor detail. It is part of a natural cycle that we would have to face anyway.
Ignoring this and charging ahead with this AGW guilt induced, self-flagellation ritual is enabling the criminalization and possible anthropocide of humanity. I think that is exactly at odds with why Jesus died for them.

I suspect not too many people with a scientific background doubt that AGW is scientifically sound or that global temperatures have increased a small amount over the past century. What I am skeptical about is (1) the percentage of that increase due to human activities, (2) the ability to model the effects accurately--that is, predict the future, and (3) the ability to do anything significant about future changes even if they're all man-made. Physically it may be possible to stop AGW, but IMO it won't be possible politically, especially if James Hansen (see Dec. 14 issue of Newsweek) is right.
141 scientists with backgrounds in climate science have just expressed similar skepticism in an open letter to Ban Ki Moon at http://www.copenhagenclimatechallenge.org/. Opening sentences: Climate change science is in a period of 'negative discovery' - the more we learn about this exceptionally complex and rapidly evolving field the more we realize how little we know. Truly, the science is NOT settled.
