THE CLIMATE CHANGE DEBATE ACCORDING TO KRUGMAN, HANSEN, AND PALIN


Credit: AZRAINMAN

Years ago, I served on the board of directors of a conservation group whose mission and purpose was to preserve an endangered species. We spent considerable time debating, discussing, and revising our bylaws and even more time reporting, debating, and balancing our balance sheets, plus the obligatory inventory of office supplies and cute plush toy souvenirs. “Merchandising with a message,” they called it. There were monthly board meetings and monthly membership meetings followed by refreshments, but how much time was actually spent preserving and protecting our charges? Ahem, not that much.

Years pass, and my transformation from human being to cephalopod is now complete. I no longer converse with human protectors but with the protected, and here is what the protected think of their benefactors: “We are doomed, DOOMED!” From the viewpoint of an endangered species, human beings are all talk and cute plush toys but no action. In the human Universe, the shortest distance between two points is through every conceivable viewpoint.

My experience in the endangered species preservation biz reminds me of the latest argument between economist Paul Krugman and climate change scientist James Hansen, who fired the first volley in this New York Times Op-Ed:
Because cap and trade is enforced through the selling and trading of permits, it actually perpetuates the pollution it is supposed to eliminate.

(…)

Coal emissions are still significant contributing factors in four of the five leading causes of mortality in the United States — and mercury, arsenic and various coal pollutants also cause birth defects, asthma and other ailments.

(…)

The House and Senate energy bills would only assure continued coal use, making it implausible that carbon dioxide emissions would decline sharply.

(…)

If that isn’t bad enough, Wall Street is poised to make billions of dollars in the “trade” part of cap-and-trade.

Not to be outdone on matters of energy economics by a lowly climate change scientist, Paul Krugman, our infamous defender of faith and turf, returned fire with this:
Things like this often happen when economists deal with physical scientists; the hard-science guys tend to assume that we’re witch doctors with nothing to tell them, so they can’t be bothered to listen at all to what the economists have to say, and the result is that they end up reinventing old errors in the belief that they’re deep insights.

What a condescending and prickly reply, I thought. Clearly, Paul Krugman represents the Cute Plush Toy School of environmental protection that amuses protectors but accomplishes little on behalf of the protected. Worse still, here is what Krugman says of Hansen’s carbon tax proposal:
If you use a tax, you know what the price of emissions will be, but you don’t know the quantity of emissions; if you use a cap, you know the quantity but not the price. Yes, this means that if some people do more than expected to reduce emissions, they’ll just free up permits for others — which worries Hansen.

What worries Hansen should also worry us. A system of cap and trade will invite chicanery from players on both sides of the equation. Polluting industries will abuse the “cap” on emissions by continually lobbying Congress for exemptions, offsets, and opt-outs. Speculators will abuse the “trade” by gaming the system in much the same way Enron manipulated energy markets and defrauded consumers. Thus, cap and trade will become the ultimate plush toy for powerful interests but accomplish little or nothing in actual emissions reduction. Furthermore, Krugman ignores Hansen’s proposal of a fee-and-dividend system which clearly states:
The fee would be uniform, a certain number of dollars per ton of carbon dioxide in the fuel. The public would not directly pay any fee, but the price of goods would rise in proportion to how much carbon-emitting fuel is used in their production. All of the collected fees would then be distributed to the public. Prudent people would use their dividend wisely, adjusting their lifestyle, choice of vehicle and so on. Those who do better than average in choosing less-polluting goods would receive more in the dividend than they pay in added costs.

(…)

Given the amount of oil, gas and coal used in the United States in 2007, that carbon fee would yield about $600 billion per year. The resulting dividend for each adult American would be as much as $3,000 per year. As the fee rose, tipping points would be reached at which various carbon-free energies and carbon-saving technologies would become cheaper than fossil fuels plus their fees. As time goes on, fossil fuel use would collapse.

While I favor Hansen’s fee-and-dividend system, we should also consider a proposal put forth by arch-conservationist extraordinaire, Sarah Palin. In her recently released bestseller, the Sarahdon said: "If God had not intended for us to eat animals, how come He made them out of meat?" We should take her at her word. If God made meat to be eaten, and if human beings are also made of meat, then it stands to reason that human beings should join her list of fair game. Her modest proposal would require only a slight modification of God’s Word. If you change “Love thy neighbor” to “Eat thy neighbor,” famine would disappear and all human impacts on the environment would diminish over time. As everyone knows, once you remove human impacts from the environment, Nature has an uncanny way of recovering and bouncing back ... quicker than a wink!

  1. No changes to God's Word are needed. "Love thy neighbor" works fine in either sense.

  2. I am not sure if I have this right, but I kind of like Hanson's system. You pay up front for what you use. It is easy. I assume that there would also be taxes for other pollutants such as the sulfur content of the oil and coal.

    But then there would be no incentive to capture or scrub the sulfur from your waste gases. There would be no desire for automotive catalytic converters -- if I am paying for the sulfur at the pump, why pay again for the additional hardware in my car? This same reasoning would apply for capturing waste CO2 and sequestering it. (That is not my favorite strategy, but it is better than releasing it into the environment!)

    (Years ago I was a big fan of Ayn Rand's Enlightened Self-Interest, but, dang it, people just *refuse* to be enlightened!)

    I don't think he meant "Eat thy neighbor" in that way.

    These ding-dongs have no reason to care about any of this. They think Jesus is coming back soon and so there's no reason to do anything about actual problems, leaving them free to concentrate on bashing gays and abortion.

    But then there would be no incentive to capture or scrub the sulfur from your waste gases.

    That's what regulation is for. Implementing a fee-and-dividend system wouldn't (have to) mean getting rid of the existing regulations on the car industry.

    I agree. My point was that no single system is perfect and that it would take several different measures to effectively reduce emissions.

  6. How soon will it be before population growth and economic advancement renders it all moot? What do we do to feed and house and provide for 10 billion - then 12 billion, then 15?

    Malthus matters. The problem is population and yet it seems to be the one part of encroaching doom we won't talk about.

  7. Actually, in order to create a scarcity of carbon we can't just limit emissions. We have to tax them. The argument here is whether to do that through user taxes (like gas taxes) or through carbon credits that create a market price for carbon emissions.

    As for changing "Love thy neighbor” to “Eat thy neighbor,” I imagine that's the natural result of Schlafly's Conservapedia Bible rewriting project.

  8. Population growth isn't going to be an issue. Birth rates are plummeting all over the world. They are already well below replacement level even in much of the Third World -- even in some Islamic countries -- and except for the most backward areas, pretty much everywhere is clearly headed in that direction.

    The biggest challenge to climate stabilization is not population growth but the economic take-off in much of Asia and Latin America. Even as population stabilizes, economic growth in those areas must accelerate to get their people to a reasonable standard of living.

    The solution there is to push ahead with the technology of clean power generation and make sure funding is available to implement it in the Third World as quickly as possible.

  9. "economic growth in those areas must accelerate to get their people to a reasonable standard of living."

    Yes, perhaps you're right and I don't think you can tell people to stay at the poverty level so we can drive Hummers and burn coal. Even if population stabilizes at 7, 8, 9 billion, the burden increases with every new set of lungs. Can the world support 9 billion at a reasonable standard of living without reducing that standard for those of us well above average?

  10. One of my environmental activist buddies read this article but did not post a comment. Instead he sent me an email that read:

    Anyway, I like the idea of "eat thy neighbor," and as you know, I was a big supporter of "cyanide pills for everyone!" If I can only find about 2 billion to volunteer to take those first pills …

    My thoughts on the above: If you advertise “cyanide pills,” it is easy to understand why volunteers might feel reluctant to participate; but if you promote it as “This Pill will Cut your Federal Income Tax by 50%” and send it to all RNC and Palin/Beck supporters, it would have a significant impact.

  11. I would only eat my neighbors if they were stegosaurs. Which are delicious, by the way, whether raw or dressed and stewed....

    As for climate change, it seems to me that humanity's fiendish cleverness (as distinguished from genuine intelligence) got it into the current mess, and that same cleverness guided by genuine intelligence is probably the only way back to sanity. Going neo-primitivist (i.e. swearing off the desire for shiny new things, getting back to the simple life, etc.) isn't a likely avenue. One can consume more responsibly, but abandoning the production-and-consumption model altogether isn't something most people are likely ever to find palatable: "the desire to desire," so to speak, is surely ineradicable.

  12. Bloggingdino: "abandoning the production-and-consumption model altogether isn't something most people are likely ever to find palatable: "the desire to desire," so to speak, is surely ineradicable."

    There is an anecdote about the boiling frog. According to the tattling tadpole, if a frog is placed in boiling water, it will jump out [or be instantly killed], but if it is placed in cold water that is slowly heated, it will not perceive the danger and end up slowly cooked to death.

    The anecdote of the boiling frog has been used to describe all those who deny an impending crisis, i.e., an economic crisis or a climate change crisis. The timeline for such events to unfold is too long for the simple-minded to comprehend.

    Personally, I think the analogy is wrong. Frogs don't like to stay in one place for very long and prefer to hop around. If I were a frog being compared to a human being, I would feel very insulted.

  13. Can the world support 9 billion at a reasonable standard of living without reducing that standard for those of us well above average?

    Yes, easily. Global population is now about 4 times what it was 100 years ago and 20 times what it was 600 years ago (or at any point before that), yet average standard of living is far higher (compare frequency of famines worldwide today with as recently as 50 years ago, for example). The reason is technological progress which enables us to exploit new resources faster than old resources run out, and use them more efficiently. Today, population growth is slowing down while technological progress is still accelerating.

    The worst remaining poverty is in places like North Korea, Burma, and Somalia. Population densities in those countries are not high by world standards. The problem is political incompetence, not overpopulation.

    Similarly, most of the worst environmental destruction is going on in tropical Africa and South America. These places are thinly populated, but poor. They don't have the resources to protect the environment. Economic development can change that.

    Global warming, too, needs to be addressed by developing clean power generation and probably some kind of planetary-engineering approach to scrubbing greenhouse gases from the atmosphere. We can't fix it by reducing the standard of living, because people won't accept that -- not in America and not in India.

    ReplyDelete
  14. Yes, the standard of living is higher, but even if we freeze further increases, the planet is degrading and the status quo isn't sustainable.

    Yes, we need clean energy, we also need to keep the population increases that come from a higher standard of living from overwhelming us. Sure, Europe isn't exploding, but India is and if we could cure some of the things plaguing Africa it would be exploding even faster. Even with fusion power - if it ever happens - I thing life would be far, far better with 6 billion than with 12 or 20 and all the ugly things that come with it.

    So you've decided against the "eat Irish babies" thing?

  16. Yes, Irish babies are in no way comparable to a good stego stew.

  17. the planet is degrading

    Not true. Overall the environment in the developed countries is in much better shape than it was 50 or 100 years ago (more forest cover, cleaner rivers, etc.) Global warming is an exception -- a major one, certainly, but with that exception the environment in rich countries is improving.

    The environment is deteriorating in poor, tropical countries, especially in those which are thinly populated. The problem is poverty, not population density.

    Europe isn't exploding, but India is

    Nope. The birth rate is dropping there as well. It might even be lelow replacement level already -- I'm not sure -- but if it isn't, it's clearly heading in that direction. Population growth continues for a while because the drop in birth rates is recent and a disproportionate share of the population is still in the child-producing years of life.

    If India had the same per-capita income as the US, it could spend the same kind of resources on protecting the environment that the US does -- even with a billion-plus people.

    Sub-Saharan Africa is the only region where the birth rate is still high. For a while it looked like the Islamic world would be an exception to the trend, but that's no longer the case. Many Islamic countries now have birth rates below replacement level.

    If the population were to reach 12 or 20 billion in the foreseeable future, it might indeed be a serious problem, but there's no way that that's going to happen. Concerns about overpopulation are based on data 10-15 years out of date. That particular problem is solving itself.

  18. Infidel753: “Overall the environment in the developed countries is in much better shape than it was 50 or 100 years ago … [India] The birth rate is dropping there as well … Many Islamic countries now have birth rates below replacement level.

    I always thought Homo sapiens were a lemming species. Notwithstanding improvements in water quality (for developed countries only), greenhouse gas emissions contradict the claim that environmental conditions are improving. The threat of rising sea levels, drought, crop failures, mass extinctions, and catastrophic population dislocations tell a very different story. One might say your comment has internal contradictions.

    Here is another perspective:

    According to the International Rice Research Institute, 80-100 million additional people must be supplied with rice each year which will require a 70% increase in production over the next 30 years.

    And yet another:

    In our opinion. a tripling of the world's food production by the year 2050 is such a remote prospect that it cannot be considered a realistic possibility. If present food distribution patterns persist the chance of bettering the lot of the majority of the world's peoples vanishes. The likelihood of a graceful and humane stabilization of world population vanishes as well. Fertility and population growth in numerous developing countries will then be forced downward by severe shortages of food, disease, and by other processes set in motion by shortages of vital resources and irreversible environmental damage.

    Most commentaries tell of dire consequences. If you have contrary evidence, I would certainly like to see it. Citations, citations, please.

  20. The reason such pessimistic predictions are wrong is the same reason that similar predictions have always been wrong in the past -- they fail to take into account the effects of accelerating technological progress. The world of 2000 would not have been possible with the technology of 1950 either. The difference is that 2000-2050 will see much lower population growth, and dramatically faster and more fundamental technological changes, than 1950-2000 did.

    ReplyDelete
  21. The assumption is then, that since technological progress has been accelerating quickly of late that it will always accelerate sufficiently to keep ahead of population growth and declining resources.

    Is that really sound? Much of what we ascribe to progress has only been the ability to use find and use resources more quickly - that does not suggest that we can't possibly use it all up or outbreed our technological prowess.

    Much hangs on practical fusion power -- that would put off the otherwise inevitable decline, yet do we want to live in a world where every inch is paved over with shopping malls and houses and roads and factories? Will cheap power restock the oceans with fish or will we have to eat synthetic food? Our unchecked biological urges inevitably drive us toward reckless expansion and short sightedness -- and denial. I don't think we're any better equipped to shed our instincts than yeast in a fermentation vat.

    And what if we never master controlled fusion?
