Markets and global warming: some heresies, Libertarian and otherwise

OK, I have formally identified myself as a pragmatic libertarian, and I have stated here and elsewhere that my difference with the scientific consensus on global warming is that I think there is adequate evidence to suggest that we are past the "tipping point," and need to become more concerned with adaptations than prevention.

I also pointed out in a comment response elsewhere that "the market" in the larger sense was already moving on to the adaptation phase faster than the government. This was misinterpreted by some as me stating that the market was moving to fix the problem and that we didn't need any governmental or international polcies, interventions, etc.

So let's clear up a few things. First, Nicholas Stern, in The Economics of Climate Change, The Stern Review makes it quite clear why "the market" has not done anything to halt or slow down global warming:

In common with many other environmental problems, human-induced climate change is at its most basic level an externality. Those who produce greenhouse-gas emissions are bringing about climate change, thereby imposing costs on the world and on future generations, but they do not face directly, neither via markets nor in other ways, the full consequences of the costs of their actions.

Much economic activity involves the mession of greenhouse gases (GHGs). As GHGs accumulate in the atmosphere, temperatures increase, and the climatic changes that result impose costs (and some benefits) on society. However, the full costs of GHG emissions, in terms of climate change, are not immediately--indeed they are unlikely ever to be--borne by the emitter, so they face little or no economic incentive to reduce emissions. Similarly, emitters do not have to compensate those who lose out because of climate change. In this sense, human-induced climate change is an externality, one that is not 'corrected' through any institution or market, unless policy intervenes.

The climate is a public good: those who fail to pay for it cannot be excluded from enjoying its benefits and one person's enjoyment of the climate does not diminish the capacity of others to enjoy it too. Markets do not automatically provide the right type and quantity of public goods, because in the absence of public policy there are limited or no returns to private investors for doing so: in this case, markets for relevant goods and services (energy, land use, innovation, etc) do not reflect the consequences of different consumption and investment choices for the climate. Thus, climate change is an example of market failure involving externalities and public goods.


Markets are nothing more and nothing less than complex economic adapting systems that individuals and groups attempt to manipulate to serve their purposes. For many purposes--a great many more than your average liberal or progressive would care to admit--markets work just fine. On the other hand, markets don't stop ethnic cleansing in Kossovo, end starvation or genocide in Darfur, or halt the Chinese invasion/destruction of Tibet.

And on a global scale with a wide mixture of industrialization and development; free market economies and command economies; cultural and religious differences severe enough to overcome all rational thought; and a lot of other issues you could name as well as I, here's an often overlooked truth:

Even if "the market" could solve problems on a global scale, THERE IS NO MARKET OPERATING AT THAT SCALE.

Some other process--some other complex adapting system--has to function at that scale for large changes to be made. The problem is, nobody really knows what that system would be, and even those who visualize stopping global warming through activist government and international action see that process in terms of governmental intervention in, and regulation of markets.

I don't think we have the theory for that yet, which scares the hell out of me.

But I do know some things about what such a theory would look like (in sort of the same way cosmologists who don't have a Grand Unifying Theory at least know the questions it must answer).

A global complex adapting economic/political system will have to take into account the following:

1. Political and economic manipulations will always create at least as many externalities (unanticipated consequences) as they resolve, and some (if not many) of these externalities will rival the original problem in terms of potential danger.

2. Predictive models that DO NOT allow for a huge factor of such emerging externalities in terms of higher costs, lower success rates, managerial crises, or unanticipated changes in technology will be WORSE THAN USELESS because they will provide false comfort.

3. Either policies or predictive models that DO NOT take into account that the vast majority of social, political, and economic activity is DRIVEN FROM BELOW regardless of the formal rules of the system will INEVITABLY FAIL.

4. No climate change mediation policy or program, no matter how draconian it is in execution, can succeed in mitigating the impact of global climate change unless and until such policies or programs take into account unrestricted population growth. (If industrialized nations are culpable for their GHG emissions, the developing world is equally culpable for failure to take action on population control.)

5. Any predictive model or policy that purports to operate on a global scale will necessarily violate the fundamental rights and freedoms of millions and millions of people in exact proportion to its effectiveness.


In other words, what I am saying is that we are facing a global problem of unprecedented proportions, and nobody has a functioning political/economic model for meeting that challenge. Worse, nobody seems that interested in developing one; at best you find hucksters dusting off their old solutions to smaller problems and hawking them as the utopian savior.

The scientists who have described and verified global warming have no more clue how to actually manage a political/ecnomic solution to it than anyone else.

What can you do about this?

In a book that I have recently lost my copy of--Larry Niven's N-Space--there is an article called something like "How wars are stopped and what you can do about it." Niven's thesis is that while most wars are fought amidst great suffering and dying, most peace talks and negotiations take place in placid, neutral surroundings, conducted on all sides by men who have never missed a meal. Therefore, while those in the trenches feel a great deal of urgency about stopping the war, these men (like the US and Vietnam in Paris) think nothing of spending a number of hours arguing over the shape of the conference table. They don't have any great impetus to actually end a war until it starts to exact a personal or political price on them (Which, if you think about it, is Stern's point above), and that will necessarily take a long time.

Then Niven closes by saying, that's the way it is, and:

"What you can do about it: nothing!"

Global warming prevention strategies will come from above, and not being driven by any sound political/economic theoretical basis, the unfortunate fact is that they'll probably fail (not, I emphasize, a reason NOT to try).

Global warming adaptations will come from below, and will be primarily technology and market-driven, and will largely be independent of those larger strategies.

That's where you and I can truly make a difference.

So buy flourescents (I started four years ago) and high MPG cars (two years ago), but realize that your children if not you are going to inhabit a fundamentally different world.

Start preparing them now.

Recycle Delaware spots are conveniently located near every town.

I turn back the hot water pressure when taking a shower, adjusting the cold to taste, which minimizes the amount of hot water used.

You can wrap your hot water pipes with some sort of insulation, and save gallons of heated water going cold over time.

Shoot, the next time it snows, look at the roof and find where heat is leaking out by the melted hotspots.

Just a few ways of cheaply reducing your footprint just by small actions.

Interesting you mention Niven. He and pal Jerry Pournelle are certainly no friends of environmentalist extremists. I recommend their book Fallen Angels for [an extreme] view of what would happen if the Al Gore's really got a hold on power.

Personally, I don't think you give the planet enough credit in the whole scheme of things. For instance, the major contributor to warming, fossil fuels, is a finite resource which countries this century will begin to turn away from. (How's that for market forces?) Warming and cooling ternds have a looooong history of waxing and waning. A mere 30 yrs. ago we were warned of the next coming Ice Age. I think it a great conceit that we believe we can very accurately predict what climate will do a hundred years from now given the myriad factors that affect it.

Hell, the US -- reviled as a non-signer of Kyoto -- actually has controlled emissions a lot better than those who DID sign the protocol. In 2006, its emissions dropped 1.3%.

I dunno Steve, maybe I'm reading too much into your "tipping point" terminology. It sounds quite apocalyptic which I think is unnecessarily hyperbolic.
The one thing I find truly odd about the conservative critique of global warming- and all its related issues- is how people go on about conservation like it's part of Al Gore's Big Lie.

If we can recycle stuff, why not? If we can use less energy, why not? If we can plan developments to be less environmentally damaging, why not? The results add up to responsible stewardship and general thrift, both of which once were virtues.

But maybe I'm behind the bubble these days, now we live in an era where we can best support a war effort by shopping.
Hube,
Sorry, traveling and could not get a response to post until tonight.

Fallen Angels is a good read but Niven himself has explicitly said he was somewhat uncomfortable with the societal premise in the set-up (which seems to have come more from co-author Mike Flynn) because the science behind it was shakey.

You say, "For instance, the major contributor to warming, fossil fuels, is a finite resource which countries this century will begin to turn away from. (How's that for market forces?"

Actually, turning to another source of energy only when the previous source has been exhausted is not something attributable to a "market force." Markets after all can only work with what is there.

"You don't give the planet enough credit in the whole scheme of things." Actually, I do. The planet's existence is not at issue: if humanity had wiped itself out via nuclear winter during the Cold War, the planet would have continued and developed new complex systems a few 100 million years later as it did after the Permian and K-T extinctions.

I'm not being apocalyptic about the "tipping point," merely observational. If you want to pursue conspiracy theories in scientific research, here's one:

The real suppressed minority of researchers are those cutting edge micro-biologists, climatologists, and extinction specialists who keep trying to publish information that suggests we HAVE crossed the threshold into major climate change. They are finding it difficult to get printed because the scientific establishment has jumped on the prevention bandwagon as the best road to influence and more grants.

Moreover, Hube, I don't necessarily think climate change will be the complete disaster that the jeremiahs are telling you. In Africa, for example, it will be very good to be Angola, which is one of the countries that will be the major beneficiary of climate change.

Climate change will also pretty much end the threat of Islamic domination of any part of the world--look closely at the projections of what's due to happen to Indonesia, Pakistan, Iran, Syria, and others.

Likewise, in terms of population demographics, the answer is simple: current rates of growth cannot be sustained, and the temporary bump to agricultural production by "good" climate during the mid-20th century and the agricultural revolution are not sufficient to permanently raise the carrying capacities of East Asia or the Indian sub-continent. This is going to be self-correcting at a monumental scale of horrific die-backs, plagues, and wars in those areas over the next 3 decades: Europe during the Black Death is going to look like a luxury vacation in comparison.

I say "prepare your children now" because unless the children of the industrialized nations acquire the scientific literacy, the political skills, and the realpolitik-based outlook on the rest of the world they are going to be in trouble.

Steve: Thanks for the correction -- it was Flynn, not Pournelle that worked w/Niven on FALLEN ANGELS. Pournelle is the more outspoken critic of the radical anti-GW (that's global warming not George Bush) advocates.

Where did you read that about Niven and his thoughts about the novel? And of course the science was "shaky" -- that's why it's called science fiction. "Shaky" science sure hasn't dissuaded Lar from writing a whole bevy of books that utilize, for instance, FTL space drives, which is about as "shaky" a science as one can get.

Actually, turning to another source of energy only when the previous source has been exhausted is not something attributable to a "market force." Markets after all can only work with what is there.

But, of course, industrialized countries will indeed be making use of the market long before the source is exhausted. They'll be reacting to the scarcity of the product (and not just its natural scarcity but the artificial barriers set up, for example, to prevent further oil exploration) and the resultant increased prices. The market is already reacting with car makers putting out more hybrids in response to consumer demand.

"Major climate change" is something that has been with the planet since time immemorial. I still think it a big conceit to think that man in his current state can actually play a major role in affecting it (sans a full nuclear exchange, as you posit).

Comment Rescue (?) and child-related gun violence in Delaware

In my post about the idiotic over-reaction to a New Jersey 10-year-old posing with his new squirrel rifle , Dana Garrett left me this response: One waits, apparently in vain, for you to post the annual rates of children who either shoot themselves or someone else with a gun. But then you Libertarians are notoriously ambivalent to and silent about data and facts and would rather talk abstract principles and fear monger (like the government will confiscate your guns). It doesn't require any degree of subtlety to see why you are data and fact adverse. The facts indicate we have a crisis with gun violence and accidents in the USA, and Libertarians offer nothing credible to address it. Lives, even the lives of children, get sacrificed to the fetishism of liberty. That's intellectual cowardice. OK, Dana, let's talk facts. According to the Children's Defense Fund , which is itself only querying the CDCP data base, fewer than 10 children/teens were killed per year in Delaw

With apologies to Hube: dopey WNJ comments of the week

(Well, Hube, at least I'm pulling out Facebook comments and not poaching on your preserve in the Letters.) You will all remember the case this week of the photo of the young man posing with the .22LR squirrel rifle that his Dad got him for his birthday with resulted in Family Services and the local police attempting to search his house.  The story itself is a travesty since neither the father nor the boy had done anything remotely illegal (and check out the picture for how careful the son is being not to have his finger inside the trigger guard when the photo was taken). But the incident is chiefly important for revealing in the Comments Section--within Delaware--the fact that many backers of "common sense gun laws" really do have the elimination of 2nd Amendment rights and eventual outright confiscation of all privately held firearms as their objective: Let's run that by again: Elliot Jacobson says, This instance is not a case of a father bonding with h

The Obligatory Libertarian Tax Day Post

The most disturbing factoid that I learned on Tax Day was that the average American must now spend a full twenty-four hours filling out tax forms. That's three work days. Or, think of it this way: if you had to put in two hours per night after dinner to finish your taxes, that's two weeks (with Sundays off). I saw a talking head economics professor on some Philly TV channel pontificating about how Americans procrastinate. He was laughing. The IRS guy they interviewed actually said, "Tick, tick, tick." You have to wonder if Governor Ruth Ann Minner and her cohorts put in twenty-four hours pondering whether or not to give Kraft Foods $708,000 of our State taxes while demanding that school districts return $8-10 million each?
