The Waxman-Markey global-warming bill cannot survive cost-benefit analysis.
JIM MANZI
Democrats in the White House and Congress are now making the most serious push ever for legislation to force reductions of U.S. carbon-dioxide emissions. The stated purpose is to reduce potential future harm from human-caused climate change, and the vehicle is a climate-and-energy bill commonly referred to as Waxman-Markey. But the reasoning behind this proposal is innumerate, even if we accept the scientific and economic assumptions of its advocates.
According to the authoritative U.N. Intergovernmental Panel on Climate Change (IPCC), under a reasonable set of assumptions for global economic and population growth, the world should expect to warm by about 2.8°C over the next century. Also according to the IPCC, a global increase in temperature of 4°C should cause the world to lose about 3 percent of its economic output. So if we do not take measures to ameliorate global warming, the world should expect to be about 3 percent poorer sometime in the 22nd century than it otherwise would be. This is very far from the rhetoric of global destruction. Because of its geographical position and mix of economic activities, the United States is expected to experience no net economic costs from such warming through the end of this century, and to begin experiencing net costs only thereafter.
A government program to force emissions reductions to avoid some of these potential future losses would impose a cost of its own: the loss in consumption we would experience if we used less energy, substituted higher-cost sources of energy for fossil fuels, and paid for projects " which are termed “offsets” " to ameliorate the effect of emissions (an example would be planting lots of trees). It’s complicated to estimate the cost of an emissions-reduction program, but the leading economists in this area generally agree that it would be large, and that we should simply let most emissions happen, because it would be more expensive to avoid them than to accept the damage they would cause. This makes sense, if you consider that most such plans (for example, Waxman-Markey) call for eliminating something like 80 percent of carbon emissions within the next 40 years or so. Even if the economy becomes more efficient over this period, such a quick transition away from our primary fossil-fuel sources will be expensive.
If a) the total potential benefit of emissions abatement is about 3 percent of economic output more than 100 years from now, b) we can avoid only some of this damage, and c) it’s expensive to prevent those emissions that we can prevent, the net benefit of emissions reduction will likely be a very small fraction of total economic output. William Nordhaus, who heads the widely respected environmental-economics-modeling group at Yale, estimates the total expected net benefit of an optimally designed, implemented, and enforced global program to be equal to the present value of about 0.2 percent of future global economic consumption. In the real world of domestic politics and geostrategic competition, it is not realistic to expect that we would ever have an optimally designed, implemented, and enforced global system, and the side deals made to put in place even an imperfect system would likely have costs that would dwarf 0.2 percent of global economic consumption. The expected benefits of emissions mitigation do not cover its expected costs. This is the root reason that proposals to mitigate emissions have such a hard time justifying themselves economically.
The mechanism for mitigation proposed in the Waxman-Markey bill is a “cap and trade” plan. The idea is quite simple: The government sets a fixed annual limit to total carbon-dioxide emissions and distributes ration cards for the right to emit a portion of this amount (that’s the “cap”); it also allows those who receive ration cards to sell them (that’s the “trade”). Now, “distributes” is an artfully chosen word: How would the government decide who gets the ration cards? One method is to sell them; another is to give them away, theoretically based on some objective criterion such as historical emissions, but in practice more likely based on campaign contributions. Waxman-Markey doesn’t specify how the distributing is to be accomplished. The Obama administration expects to sell ration cards, bringing the government $80 billion a year in revenue over the next decade. This revenue represents a cost increase for more or less any company that uses lots of fossil-fuel energy in one way or another (i.e., most of the economy). Like all raw-material cost increases, these will be passed along to consumers in the form of higher prices. So in reality this is a backdoor tax on energy that conscripts private companies into being collection agents.
Would these costs be justified by the benefits we could expect Waxman-Markey to create? No, for the reasons outlined above.
Let’s start with the costs. The Environmental Protection Agency (EPA) has done the first cost estimate for Waxman-Markey. It finds that by 2020 Waxman-Markey would cause a typical U.S. household to consume about $160 less per year than it otherwise would, and about $1,100 less per year by 2050. (This projection does not factor in potential benefits from avoiding warming.) That doesn’t sound like the end of the world, but this cost estimate is based on a number of assumptions that are unrealistic, to put it mildly.
First, it assumes that every dollar collected by selling the right to emit carbon dioxide will be returned to taxpayers through rebates or lowered taxes. Waxman-Markey establishes this intention but doesn’t describe how it would be achieved, which reflects the political difficulty of achieving it. Second, it assumes no costs for enforcement and other compliance measures. Third, it assumes that large numbers of cheap emissions credits from foreign countries will be available for purchase; without these, costs to our domestic companies would be far higher. Fourth, it assumes that the rest of the world will begin similar carbon-reduction programs. (Lack of such foreign action would either increase U.S. costs or risk a trade war if we tried to compensate for lack of international cooperation with targeted tariffs.) Fifth, it assumes that there will be no exemptions, free ration cards, or other side deals " that is, no economic drag created by the kind of complexity that has attached to every large, long-term revenue-collection program in history.
The EPA forecast is something like an estimate of what would happen in a laboratory, under ideal conditions; in the real world, expected costs are far above 0.8 percent of economic consumption by 2050. The EPA does not forecast costs beyond 2050.
Remember that the U.S. should not expect any net economic damage from global warming before 2100. That is, the bill’s benefits would accrue to U.S. consumers " who are also bearing its costs " sometime in the next century. The EPA underestimate has costs rising from zero to 0.8 percent of consumption between now and 2050, and offers no projection beyond that year; but to what level would costs rise over the more than 50 years between 2050 and the point in the 22nd century when we might actually expect some net economic losses from global warming? The answer is likely to be much higher than 0.8 percent of consumption.
Now consider the potential benefits, of which neither the EPA nor the bill’s sponsors have produced an estimate. Climatologist Chip Knappenberger has applied standard climate models to project that, under the scenario for global economic and population growth referenced above, Waxman-Markey’s emissions reductions would have the net effect of lowering global temperatures by about 0.1°C by 2100. Remember that the estimated cost of a 4°C increase in temperature (40 times this amount) is about 3 percent of global economic output. Assume for the moment that global warming has the same impact on the U.S. as a percentage of GDP as it does on the world as a whole (an assumption that exaggerates the impact on the U.S.). A crude estimate of the U.S. economic costs that Waxman-Markey would avoid sometime later than 2100 would then be about one-fortieth of 3 percent, or about 0.08 percent of economic output. This number is one-tenth of 0.8 percent, the EPA’s estimate of consumption loss from Waxman-Markey by 2050. To repeat: The costs would be more than ten times the benefits, even under extremely unrealistic assumptions of low costs and high benefits. More realistic assumptions would make for a comparison far less favorable to the bill.
I’ve had to rely on informal studies and back-of-envelope calculations to do this cost/benefit analysis. Why haven’t advocates and sponsors of the proposal done their own? Why are they urging Congress to make an incredible commitment of resources without even cursory analysis of the economic consequences? The answer should be obvious: This is a terrible deal for American taxpayers.
Henry Waxman

One potential objection to my analysis is that the bill is part of a global drive for all countries to reduce emissions, and that the U.S. needs to “show leadership.” By this logic, we should ascribe much larger benefits to the Waxman-Markey bill " specifically, the benefits to American consumers of the whole world’s engaging in similar programs. There are two obvious problems with this argument, however. First, ascribing all of the benefits of a global deal to reduce emissions to a specific bill that does not create such a commitment on the part of any other countries is loading the dice. The benefit we should ascribe to the bill is rather that of an increase in the odds of such a global deal. But would Waxman-Markey actually increase them, or might it decrease them instead? Whenever one nation sacrifices economic growth in order to reduce emissions, the whole world can expect to benefit, because future temperature should decrease for the entire globe. Every nation’s incentive, therefore, is to free ride on everybody else. Our most obvious leverage with other emitting nations would be to offer to reduce our emissions if they reduced theirs. Giving up this leverage and hoping that our unilateral reductions would put moral pressure on China, Russia, Brazil, and similar countries to reduce their emissions reveals a touchingly sunny view of human nature, but it is a poor negotiating strategy. Second and more fundamentally, even if the whole world were to enact similar restraints on emissions, the economics would still not be compelling, for the reasons outlined at the beginning of this article.
A second potential objection to my analysis is that we owe it to the rest of the world to limit our emissions because of our historical role as an emitter. What this ignores is that the reason the U.S. and Europe have historically emitted carbon dioxide is that they invented the modern economy. Along with putting all that carbon dioxide in the air, the West invented the polio vaccine, the limited-liability corporation, the high-efficiency power turbine, and so on. It invented, that is, the tools for creating wealth that successful parts of the developing world are now using to escape poverty " and, incidentally, to emit more carbon dioxide. It is less than obvious why we should put a special burden on the West to make reparations for carbon-dioxide emissions while ignoring the fact that the net global effect of the system that created these emissions has been extremely positive. Ask yourself this question: Would you rather be born at the median income level in Bangladesh today, or at the median income level in Bangladesh in an alternative world in which the entire Northern Hemisphere never escaped life at the subsistence level " that is, to live in a world of lower carbon emissions, but no science, no hospitals, no foreign aid, and no meaningful chance of changing the material conditions of your life? If advocates of Waxman-Markey intend it to be, in effect, an increase of $80 billion per year in spectacularly inefficient foreign aid for people yet to be born in equatorial regions of the globe, they should at least be clear about this.
A third and more serious potential objection to my analysis is that while Waxman-Markey may not create benefits if the projections I offered above turn out to be accurate, climate science is highly inexact, and the bill is an insurance policy against higher-than-expected costs. Now, climate and economics modelers aren’t idiots, so it’s not as though this hadn’t occurred to them. Competent modelers don’t assume only the most likely case, but build probability distributions for levels of warming and associated economic impacts (e.g., there is a 5 percent chance of 4.5°C warming, a 10 percent chance of 4.0°C warming, and so on). The economic calculations that compose, for example, the analysis by William Nordhaus that I cited earlier are executed in just this manner. So the possibility of “worse than expected” impacts means, more precisely, the possibility of “impacts worse than those derived from our current probability distribution.” That is, we are concerned here with the inherently unquantifiable possibility that our entire probability distribution is wrong.
This concept has been called, somewhat grandiosely, the “precautionary principle.” Once you get past all the table-pounding, this is the crux of the argument for emissions abatement. It is an emotionally appealing political position, as it is easy to argue that we should oppose some consumption now to head off even a low-odds possibility of disaster.
But this is to get lost in the world of single-issue advocates and become myopic about risk. We face lots of other unquantifiable threats of at least comparable realism and severity. A regional nuclear war in central Asia, a global pandemic triggered by a modified version of the HIV virus, and a rogue state weaponizing genetic-engineering technology all come immediately to mind. Any of these could kill hundreds of millions of people. Scare stories are meant to be frightening, but we shouldn’t become paralyzed by them.
In the face of massive uncertainty on multiple fronts, the best strategy is almost always to hedge your bets and keep your options open. Wealth and technology are raw materials for options, and a much more sensible strategy to deal with climate risk would emphasize technology rather than taxes. The role for the U.S. federal government is to fund prediction, mitigation, and adaptation strategies.
The danger here, of course, is that we may end up back in the failed game of industrial policy. The federal government, after all, was the key sponsor of, for example, the shale-oil and large-scale-wind-turbine debacles in response to the energy crisis 30 years ago. Setting the right scope for such a program and managing the funding process carefully would be essential, to prevent it from becoming corporate welfare.
Government investments should meet specific criteria: They should be related to detecting or ameliorating the effects of global warming, serve a public rather than a private need, and provide no obvious potential source of profit to investors if successful. Examples would include improved global-climate-prediction capability, biotechnology to capture and recycle carbon-dioxide emissions, and geo-engineering projects to change the albedo of the earth’s surface or atmosphere. In contrast, most technologies that would contribute to the ongoing long-run transition of the economy away from fossil fuels, such as more efficient fuel cells for autos or lower-cost solar-power sources, need no government funding, since there is ample profit motive to develop them. Massive amounts of venture funding and large-company internal capital allocations are flowing to these opportunities right now. Government attempts to direct such development would almost certainly destroy value through political allocation of resources.
The agency for funding any government-sponsored research should be explicitly modeled on the Defense Advanced Research Projects Agency (DARPA). It should have a very-high-IQ staff with wide flexibility in providing small grants, and emphasize large prizes for accomplishing measurable and audacious goals. The British entrepreneur Richard Branson has offered a $25 million prize to anyone who demonstrates a device that removes significant amounts of carbon from the atmosphere. What if the U.S. government upped the ante to $1 billion and pledged to make any resulting technology freely available to the world? That would solve any global-warming problem that might develop, at a one-time cost of less than 0.01 percent of U.S. GDP. Of course, this agency would still be a government program, and therefore rife with inefficiencies. But consider that its costs would be on the order of 1/100th of the costs of imposing a large U.S. carbon tax.
Clarity about costs and benefits is the enemy of the Waxman-Markey proposal. To get drawn into the details of tweaking allowance schedules or emissions limits, in the hope of avoiding the appearance of obstructionism, is a sucker play. No amount of tinkering is going to change the fundamental reality that even a perfect implementation of the Waxman-Markey concept is a very poor economic deal for Americans. The alternative should not be tax-based or rationing-based efforts to make energy more expensive, but a targeted research program to provide insurance against unanticipated and unpredictable consequences. At the other extreme, to make this an argument about climate science by attacking the global scientific establishment, or to engage in a debate about worldviews and socialism " that is, to operate on a high rhetorical plane " is also a sucker play, because it allows advocates of Waxman-Markey to continue to avoid the hard issue of costs and benefits. We should keep coming back to one practical question: What do we pay, and what do we get?
Mr. Manzi is a senior fellow at the Manhattan Institute and chairman of an applied-artificial-intelligence software company.
For those who do not wish to read the entire Manzi column, it says, in essence---
The costs of Waxman-Markey would be more than ten times the benefits, even under extremely unrealistic ASSUMPTIONS of low costs and high benefits.
I am certain that Parados can not and will not attempt to rebut Manzi's article.
Too bad because there are such things as Cost-Benefit analyses!
Scientists say Kyoto protocol is 'outdated failure'
By Steve Connor, Science Editor
The international effort to curb man-made emissions of greenhouse gases " as enshrined in the Kyoto protocol " is a miserable failure that needs to be swept away and replaced, according to a new report.
Climate policy after 2012, when the Kyoto agreement comes to an end, will disintegrate unless the principles behind the present treaty are overhauled and a new approach is taken, says the study, published in the journal Nature.
"The Kyoto protocol... as an instrument for achieving emissions reductions, has failed," it says. "It has produced no demonstrable reductions in emissions or even in anticipated emissions growth."
Gwyn Prins, of the London School of Economics, and Steve Rayner, of Oxford University, criticise Kyoto for being the wrong tool for controlling emissions.
Too often, they say, its failure is blamed on the US and Australia for not signing up to it. They argue that the protocol was misconceived from the start because it was based on previous international treaties to protect the ozone layer, to stop acid rain and to control the proliferation of nuclear weapons.
"This borrowing simply failed to accommodate the complexity of the climate-change issue," they say. "Kyoto has failed... also because it has stifled discussion of alternative policy approaches."
To all who contribute to this thread--
All of this posting will be irrelevant after the Climate conference is over. This conference will be held in December 2009 in Copenhagen. Anyone, even the esteemed president of the United States who presses for ruinous economic constraints which will cause a loss of Millions of Jobs, should be ignored WHEN China and India refuse to go along with the proposals to "reduce" the "alleged" global warming because they are developing countries.
Signals have already been sent by China and India that they will not co-operate unless a huge subsidy is given to them. v

Well, it is. And since official weather stations are regulated and all ISO-/SAE-/ AEA- certified - what's the problem?
@Walter Hinteler,
The problem is exactly what Okie has been illustrating, and our continuing concerns that the AGW religionists and opportunists will 'cook the books' on what data is reported. I think they are not ethically opposed to scaring people into compliance regardless of whether they actually have sufficient evidence to justify their efforts to control more and more of our lives.
My concern remains what it has always been. If I am going to give up personal freedom, choices, options, or opportunities to 'save the planet', I want to make darn sure that it is based on solid, honestly interpreted science, and not on theories presented as science to preserve somebody's funding.
@Foxfyre,
To be honest: I've more belief in data from certified stations than in okie's posts.

@Foxfyre,
Thanks, Foxfyre. I would never claim to be right all the time, but my interest in weather stations is for sure stimulated by the information out there. Going back a long time on this forum, I don't know if you remember the discussion, but I was quick to say my experience in the scientific world had turned me into a person with a healthy skepticism when reading so-called news reports of science. You really need to look at the background data, etc., and be skeptical. I have personally seen alot of junk science attempted, and I also clearly remember the difference between what we were taught in college, and what was actually observed and thought in the practice of the disciplines involved, mine being geology. I believe the same can be applied to almost all scientific fields. I do believe science works, but initially the theories out there sort of take a scatter approach in a general direction, or even in several directions, and as time moves on, the scatter may diminish and tend to focus better, as we learn more and more, but as new things are discovered, it opens up even more unknowns to solve. But climate science is really in its infancy I believe, and I think the whole issue is riddled with errors and inaccuracies at this point in time. And what makes it all the much worse is that politics is a huge component of the issue, which increases the liklihood of misinformation, errors, and basically junk science.
To repeat a line from the above article I quoted:
"They found 89 percent of stations “fail to meet the National Weather Service’s own siting requirements” that say stations must be located at least 100 feet from artificial heat sources."
@okie,
I may have expressed our experience with this here in Albuquerque, but if I'm repeating myself, I'm allowed to be more forgetful in my 'old age'.
If you are familiar with 'weatherunderground', you know it reports data from private weather stations scattered around a specific region. For instance, when it is running, I tie into the data at one of these stations that is about a half mile from my house. If that station isn't operating on a given day, the website will default to another station that is further away but still in the general area.
Anyhow, when some of us noted on local blogs that there was a wide discrepancy in the data reported by some of the stations--one station might be reporting temperature 5 to 10 degrees warmer than one a mile away from it for instance--one of our local TV guys got curious. Armed with a yellow pad and camera, he set out to check on all these private weather stations that he could find. And he reported that he found stations placed on concrete patios, next to air conditioner compressors, under thick shade trees, next to clothes dryer vents, etc etc. etc. He anticipated that about a third to one half of the stations were rendering skewed data based on their locations.
I think your sources are relating much the same kind of thing related to the Weather Service's monitoring stations in the USA and that is probably true of at least some other countries as well. Then there are vast areas of ocean, rain forest, desert, and other sparsely inhabited or visited areas of the world where there are no monitoring stations at all.
This may or may not be hugely significant in the overall big picture, but I certainly think it belongs in the files of those who are interested in the truth of the matter rather than just promoting the ideological or politically correct or financially motivated position.
(If you're not familiar with weatherunderground, just type in your city along with weatherunderground in your browser and you'll get a link. Example: Albuquerque NM weatherunderground. I believe they have stations throughout most of at least the free world.)
@Foxfyre,
Thanks, that is interesting. I should look up the links you suggest.
Your point about the paucity of weather stations in much of the unpopulated world is a good one, wherein the temps for those areas end up being interpolated over greater distances. Therefore, key stations that deliver bad data could affect larger areas greatly, I would think. Back in the days of geology, we had to attempt to estimate ore reserves of an orebody based upon drill hole information. The wider the spacing, the more uncertain the estimates, and if you had anomolously strong or weak ore intercepts that were interpolated too far, you end up with skewed estimates. Also, different methodologies of calculations give different results. Knowing trends and likely geometric shapes helped define or refine the best calculation methods. I am not totally familiar with what math or computer generated spatial calculations are used for climate, but I intuitively believe the calculations could be highly suspect, given the task at issue here. Considering we are only talking about a fraction of a degree, I think placing too much significance in differences of tenths or hundreths of a degree Centigrade is really exceeding the degree of accuracy possible.
@okie,
1. Are you sure it is a station used by GISS or HADCRUT?
Both try to stick with stations with at least 100 years of records.
2. There is no evidence of the station changing in the last 30 years. If the station is reading hot because of where it is located it will ALWAYS read hot so the station will show changes even if they are always warmer than they should be. George pointed that out already and you ignored it.
3. Can you tell us which station this supposedly is a picture of? I have seen nothing that designates it an official station.
@okie,
89% of the ones they checked using biased checkers.
1. They have NOT checked all the stations.
2. They rely on measurements from people that WANT them to not meet the standards.
3. They don't bother to check and confirm if they are correct or not.
4. The list seems to imply that 32m fails the 100feet test based on the notes for stations.
@Foxfyre,
Your certainly familiar with the US Air Force, at least with the Albuquerque facilities.
Ask someone from the Operational Weather Squadron there, why they don't use private data for their weather charts.
Oh, and your 'official' local weather uses the data from Kirtland Air Force Base. As does wonderland.
Weather stations aren't certified if they don't have certain standards. (I really wonder who the station, okie posted a photo of, can give the temperature on the ground and in two meter height.)
@okie,
OKIE, there are many, many stations like that and worse all over this country.
Some with 100 watt bulbs inside burning 24/7 and some on airport jet ways in direct proximity to jet blast...

Here is who did the study, quoted from the linked article I posted, which included or was part of an editorial in the Orange County Register:
“We can’t know for sure if global warming is a problem if we can’t trust the data,” said Anthony Watts, veteran broadcast meteorologist, who for three years organized an extensive review of official ground temperature monitoring stations, in conjunction with Dr. Roger Pielke Sr., senior research scientist at the Cooperative Institute for Research in Environmental Sciences and professor emeritus of the Department of Atmospheric Science at the University of Colorado.
The study, recently published by the free-market Heartland Institute, inspected 860 of the 1,221 U.S. ground stations that gauge temperature changes. The findings were alarming.
They found 89 percent of stations “fail to meet the National Weather Service’s own siting requirements” that say stations must be located at least 100 feet from artificial heat sources.
