The strangely narrowing argument linking climate change to global conflict [updated]

OP-ED: "Terror In the Weather Forecast," by Thomas Homer-Dixon, New York Times, 24 April 2007, p. A25.
Homer-Dixon is a smart guy, but he peddles the worst sort of mushy fear mongering, constantly declaring the world near collapse from all its brittleness, lack of ingenuity, system vulnerabilities and the like.
Naturally, he loves the potential of global warming, citing CNA's recent study by retired flags where they all opine ominously, but with no real sense of historical causality, about how climate change equates to a "threat multiplier."
History actually provides scant evidence that disasters or tough weather or water shortages cause war. Truly, the historical record portrays more the opposite: people tend to come together in hard times.
Now, if you want to say economic collapse, then your argument improves, but as I've said before, all indications are that it will pay to be rich in the global climate change future, and that it will suck to be poor--no matter where you live. My answer to that is to make people richer, especially those poor now, and I start that process with connectivity.
Read this concluding bit from Homer-Dixon:
By weakening rural economies, increasing unemployment and disrupting livelihoods, global warming will increase the frustrations and anger of hundreds of millions of people in vulnerable countries. Especially in Africa, but also in some parts of Asia and Latin America, climate change will undermine already frail governments--and make challenges from violent groups more likely--by reducing revenues, overwhelming bureaucracies and revealing how incapable these governments are of helping their citizens.
Okay, I'll buy that. I'll also buy that a lot of bad things in this world make those bad trends worse, and I'll also argue--in the vein of Bjorn Lomborg--that, bang for the buck, there's a ton of better ways to address every bad thing on Homer-Dixon's list before turning to global warming, the course of which we can tilt but slightly, but not without significant shorter-run costs (stretching across decades) whose unintended side effects--I'm gonna go out on a limb here--are far larger than we can imagine.
I'm not saying don't do whatever makes reasonable sense to cut CO2 emissions. I love new technology. I want it spread everywhere. I love new and better ways of making energy happen. I want those spread everywhere too.
But when I read Homer-Dixon on this stuff, I can't help but wonder how many other subject causes can easily be inserted into this generalized logic of his. I mean, a lot of things out there reduce revenues in frail states. A lot of things overwhelm bureaucracies in frail states. A lot of things reveal how incapable weak states are in meeting the needs of their citizens.
So why this amazing bandwagoning on the link between global climate change and increased instability and conflicts?
Because, I've got to tell you, if you think going after CO2 emissions is how we shrink the Gap, I think you're losing your grip on reality. To me, this rush to pile on here is just plain odd, reflecting that Calgon-take-me-away sense so many people seem to be getting on the Long War against radical extremism, which--yeah--will get more extreme if the Gap suffers more due to warming, but global warming sure as hell ain't its driver, nor the driver of frail states, nor the cause of disconnectedness, which tends to be complex even as--yes again--it will probably get worse with global warming.
I'm just saying, dealing with global warming is not rising to some great challenge of the future security environment. It's rising to the great challenge of the future environmental environment.
Yes, a great thing to pursue. But there are many great things to pursue, and while everything connects to everything, casting those connections in terms of simplistic one-way causalities is--to me--not very helpful.
I guarantee you, that whatever's freaking people out most is what Homer-Dixon is running with hardest. If tomorrow climate change gets boring, he's onto something else that will--naturally, inevitably, inexorably--lead to our civilizational downfall.
But to me, listening to security people all of a sudden fall in love with global climate change as "the next big thing" is somewhat sad. Security doesn't flow from one source, but from many, the most important one being rules. We have far more rules on the environment today than we did yesterday, and we'll have far more tomorrow.
That's all good.
But a rising environmental challenge itself is not a cause for security alarmism. It's logically a cause for better environmental policies, smarter business practices, and marketizing more opportunities for human ingenuity, which is--contrary to Homer-Dixon's patronizing tone--inexhaustible.
