Bill Gates’ considerable philanthropic efforts through the Gates Foundation are well known. Much of the foundation’s activity has focused on disease control and nutrition around the globe. Education reform has also been a priority. Many of these projects are laudable, though I’m repulsed by a few (see here and here). During the coronavirus pandemic, Gates has spoken approvingly of Non-Pharmaceutical Interventions (lockdown measures), which are both coercive and ineffective (and see here). He has earned the enmity of anti-vaxers, of course, though I’m not anti-vax as long as the jabs are voluntary. The Gates Foundation funded the World Health Organization’s effort to provide guidance on digital vaccine passports, which is a de facto endorsement of discrimination based on vaccination status. His priorities for addressing climate change also raise some troubling issues, a few of which I address below.

Squeezing Policy from a Definition

Gates put a special Malthusian twist on a TED Talk he did back in 2010 using an equation for carbon dioxide emissions, which he’s reprised over the years. It gained a lot of notice in 2016 when a few sticklers noticed that his claim to have “discovered” the equation was false. The equation is:

CO2 = P x S x E x C,

where P = People, S = Services per person, E = Energy per service, and C = CO2 per energy unit.

This equation first appeared as the so-called Kaya Identity in a scientific review in 2002. Such an equation can be helpful in organizing one’s thoughts, but it has no operational implications in and of itself. At one level it is superficial: we could write a similar identity for almost anything, like the quantity of alcohol consumed in a year, which must equal the population times the ounces of alcohol per drink times the number of drinks per person. At a deeper level, it can be tempting to build theories around such equations, and there is no question that any theory about CO2 must at least preserve the identity.

There’s an obvious temptation to treat an equation like this as something that can be manipulated by policy, despite the possibility of behavioral links across components that might lead to unintended consequences. This is where Gates gets into trouble.

Reality Checks

As David Solway writes, Gates’ jumped to the conclusion that population drives carbon emissions, reinforcing a likely perspective that the human population is unsustainable. His benevolent solution? A healthier population won’t breed as fast, so he prescribes more vaccinations (voluntary?) and improved health care. For good measure, he added a third prong: better “reproductive health services”. Let’s see… what share of the 0.9 -1.4 billion reduction in world population Gates prescribed in 2016 would have come from terminated pregnancies?

In fact, healthier people might or might not want more children, but lower child mortality in the developing world would reduce certain economic incentives for high fertility. Another reliable association is between income and child bearing: an increase in “services per person” is likely to lead to smaller families, but that wasn’t given any emphasis by Gates. Income growth is simply not part of the narrative! Yet income growth does something else: it allows us to more easily afford the research and investments required for advanced technologies, including cleaner energy. These things take time, however.

Solway points to other weaknesses in Gates’ interpretation of the Kaya Identity. For example, efforts to slow population growth are not reliably associated with “services per person”, fuel efficiency, or carbon efficiency. In other words, carbon emissions may be powerfully influenced by factors other than population. China is a case in point.

Centralized industrial and social planning is generally ill-suited to advancing human well being. It’s especially suspect if the sole objective is to reduce carbon emissions. But Gates knows that lowering emissions without a corresponding drop in real income requires continuing technological advances and/or more efficient decisions about which technologies to deploy. He is a big advocate of developing cheap hydrogen power, which is far from a reality. He is also excited about carbon capture technologies, which are still in their infancy.

Renewables like wind and solar power play a large part in Gates’ vision. Those technologies cannot deliver a reliable flow of power, however, without either adequate backup capacity or a dramatic advance in battery technology. Gates over-promotes wind and solar, but I give him credit for acknowledging their intermittency. He attempts to come to grips with it by advocating nuclear backup, but it’s just not clear that he has integrated the incremental cost of the necessary backup capacity with other direct costs of these renewables… not to mention the considerable environmental costs imposed by wind and solar (see the “back-to-nature” photo at the top for a cogent illustration). Power storage at scale is still a long way off, and its cost will be significant as well.

We could deploy existing energy technologies to greater advantage with respect to carbon efficiency. We’ve already reduced CO2 emissions in the U.S. by substituting natural gas for less carbon-efficient fuels, but the Biden Administration would rather discourage its use. Gates deserves credit for recognizing the huge role that nuclear energy can play in providing zero-carbon power. Despite that, he still can’t quite bring himself to admit the boneheadedness of heavy reliance on intermittent renewables.

Bill’s “Green Premium”

Gates seems to have deemphasized the Kaya Identity more recently. Instead, his focus has shifted to the so-called “green premium”, or the incremental cost of using zero-carbon technology relative to a traditional source. Needless to say, the premium is large for truly zero-carbon sources, but Gates emphasizes the importance of using the green premium to guide development even in the here and now.

That’s fine, but it’s not clear that he gives adequate consideration to cases in which emissions, while not eliminated, can be reduced at a negative incremental cost via appropriate substitution. That describes the transition to natural gas from other fuels. This is something that markets can do without the assistance of ham-handed interventionists. Gates prefers nuclear power and says natural gas is “not a real bridge technology” to a zero carbon future. That’s short-sighted and reflects an absolutist mindset that ignores both the economic and political environment. The thinking is that if it’s not zero emissions, it’s not worth doing.

Gates emphasizes the need to sharply reduce the range of green premia on various technologies to achieve net-zero carbon emissions by 2050. But the goal of net-zero emissions 2050 is based on the highly unlikely proposition that global catastrophe awaits failing net-zero. In fact, the predicted consequences of doing nothing are based on drastic and outdated carbon growth scenarios and rudimentary carbon-forcing models that have proven to be severely biased to the upside in terms of predicting global temperature trends.

The idea that 2050 is some kind of “deadline” is a wholly arbitrary determination. Furthermore, the absolutism with which such goals are stated belies a failure to properly assess the true costs and benefits of carbon-based energy. If we so much as accept the notion that fossil fuels have external costs, we are then expected to accept that zero carbon emissions is optimal. This is not “science”; it is doctrine propped-up by bizarre and false scare stories. It involves massive efforts to manipulate opinion and coerce behavior based upon shoddy forecasts produced by committee. Even carbon capture technology is considered “problematic” because it implies that someone, somewhere, will use a process that emits CO2. That’s a ridiculous bogeyman, of course, and even Gates supports development of carbon capture.

Conclusion

I’ve never felt any real antipathy for Bill Gates as a person. He built a fortune, and I used his company’s software for most of my career. In some ways I still prefer it to macOS. I believe Gates is sincere in his efforts to help humanity even if his efforts are misdirected. He seems to reside on the less crazy end of the spectrum of climate alarmists. He’s putting a great deal of his private resources toward development of technologies that, if successful, might actually lead to less coercion by those attempting to transform private energy decisions. Nevertheless, there is menace in some of the solutions to which Gates clings. They require concerted action on the part of central authorities that would commandeer private resources and abrogate liberty. His assertion that the world is over-populated is both dubious and dangerous. You can offer free health care, but a conviction that the population must be thinned can lead to far more radical and monstrous initiatives.

The “green premium” promoted by Gates is an indirect measure of how far we must go to achieve parity in the pricing of carbon and non-carbon energy sources, as if parity should be an objective of public policy. That proposition is based on bad economics, fraudulent analyses of trends in carbon concentrations and climate trends, and a purposely incomplete menu of technological alternatives. Yes, the green premium highlights various technological challenges, but it is also a direct measure of how much intervention via taxes or subsidies are necessary to achieve parity. Is that a temptation to policymakers? Or does it represent a daunting political barrier? It’s pretty clear that the “median voter” does not view climate change as the only priority.

Green Climate Policy Wreaks Poverty

Have no doubt: climate change warriors are at battle with humanity itself, ostensibly on behalf of the natural world. They would have us believe that their efforts to eliminate the use of fossil fuels are necessary to keep our planet from becoming a blazing hothouse. However, the global temperature changes we’ve witnessed over the past 150 years, based on the latest Assessment Report (AR6) from the Intergovernmental Panel on Climate Change (IPCC), are well within the range of historical variation.

“Remodeled” History

Jennifer Marohasy posted an informative discussion of the IPCC’s conclusions last month, putting them into a broader climatological context and focusing in particular on measurement issues. In short, discussing “global” temperatures with any exactitude is something of a sham. Moreover, the local temperature series upon which the global calculations are based have been “remodeled.” They are not direct observations. I don’t think it’s too crude to say they’ve been manipulated because the changed records are almost always in one direction: to “cool” the past.

Judith Curry is succinct in her criticism of the approach to climate change adopted by alarmist policymakers and many climate researchers: 

“In a nutshell, we’ve vastly oversimplified both the problem and its solutions. The complexity, uncertainty, and ambiguity of the existing knowledge about climate change is being kept away from the policy and public debate. The solutions that have been proposed are technologically and politically infeasible on a global scale.”

We need a little more honesty!

The Real Victims

I want to focus here on some of the likely casualties of the war on fossil fuels. Those are, without a doubt, the world’s poor, who are being consigned by climate activists to a future of abject suffering. Joel Kotkin and Hügo Krüger are spot-on in their recent piece on the inhumane implications of anti-carbon ideology.

Energy-poor areas of the world are now denied avenues through which to enhance their peoples’ well being. Attempts to fund fossil-fuel power projects are regularly stymied by western governments and financial institutions in the interests of staving off political backlash from greens. Meanwhile, far more prosperous nations power their economies with traditional carbon-based energy sources. Most conspicuously, China continues to fuel its rapid growth with coal and other fossil fuels, getting little pushback from climate activists. If you’re wondering how the composition of energy output has evolved, this time-lapse chart is a pretty good guide.

One of the most incredible aspects of this situation is how nuclear energy has been spurned, despite its status as a proven and safe solution to carbon-free power. This excellent thread by Michael Schellenberger covers the object lesson in bad public policy offered by the proposed closing of the Diablo Canyon nuclear plant in California.

In both the U.S. and other parts of the world, as Kotkin and Krüger note, it is not just the high up-front costs that lead to the rejection of these nuclear projects. The green lobby and renewable energy interests are now so powerful that nuclear energy is hardly considered. Much the same is true of low-carbon natural gas: 

“Sadly, the combination of virtue-signaling companies and directives shaped by green activists in rich countries – often based on wildly exaggerated projections, notes former Barack Obama advisor Steve Koonin – make such a gradual, technically feasible transition all but impossible. Instead, it is becoming increasingly unlikely that developing countries will be able to tap even their own gas.”

Energy is the lifeblood of every economy. Inadequate power creates obstacles to almost any form of production and renders some kinds of production impossible. And ironically, the environmental consequences of “energy poverty” are dire. Many under-developed economies are largely dependent on deforestation for energy. Without a reliable power grid and cheap energy, consumers must burn open fires in their homes for heat and cooking, a practice responsible for 50% of child pneumonia deaths worldwide, according to Kotkin and Krüger.

Green Environmental Degradation

Typically, under-developed countries are reliant on the extraction of natural resources demanded by the developed world:

“The shift to renewables in the West, for example, has increased focus on developing countries as prime sources for critical metals – copper, lithium, and rare-earth minerals, in particular – that could lead to the devastation of much of the remaining natural and agricultural landscape. … Lithium has led to the depletion of water resources in Latin America and the further entrenchment of child labor in the Democratic Republic of the Congoas the search for cobalt continues.”

Unfortunately, the damage is not solely due to dependence on resource extraction:

“The western greens, albeit unintentionally, are essentially turning the Third World into the place they send their dirty work. Already, notes environmental author Mike Shellenberger, Africans are stuck with loads of discarded, highly toxic solar panels that expose both the legions of rag-pickers and the land itself to environmental degradation – all in the name of environmentalism.”

Battering the Poor In the West

Again, wealthy countries are in far better shape to handle the sacrifices required by the climate calamitists, but it still won’t be easy. In fact, lower economic strata will suffer far more than technocrats, managers, and political elites. The environmental left leans on the insidious lever of energy costs in order to reduce demand, but making energy more costly takes a far larger bite out of the budgets of the poor. In another recent piece, “Jim Crow Returns to California,” Kotkin discusses the disparate impact these energy policies have on minorities. 

“This surge in prices derives from the state’s obsession — shared by the ruling tech oligarchs — with renewable energy and the elimination of fossil fuels. Yet as a recent Massachusetts Institute of Technology (MIT) report has shown, over-reliance on renewables is costly, because it requires the production of massive (and environmentally unfriendly) battery-storage capacity — the price of which is invariably passed on to the taxpayer.

This is not bad news for the tech oligarchs, who have been prominent among those profiting from ‘clean energy’ investments. But many other Californians, primarily those in the less temperate interior, find themselves falling into energy poverty or are dependent on state subsidies that raise electricity prices for businesses and the middle class. Black and Latino households are already forced to pay from 20 to 43% more of their household incomes on energy than white households. Last year, more than 4 million households in California (30% of the total) experienced energy poverty.”

Kotkin touches on other consequences of these misguided policies to minority and non-minority working people. In addition to jobs lost in the energy sector, a wide variety of wage earners will suffer as their employers attempt to deal with escalating energy costs. The immediate effects are bad enough, but in the long-run the greens’ plans would scale back the economy’s productive machinery in order to eliminate carbon emissions — net zero means real incomes will decline! 

Energy costs have a broad impact on consumer’s budgets. Almost every product imaginable is dependent on energy, and consumer prices will reflect the higher costs. In addition, the “green” effort to curtail development everywhere except in high-density transit corridors inflates the cost of housing, inflicting more damage on workers’ standards of living.

Tighten Your Belts

These problems won’t be confined to California if environmental leftists get their version of justice. Be prepared for economic stagnation for the world’s poor and a sharply reduced standard of living in the developed world, but quite unnecessarily. We’ll all pay in the long run, but the poor will pay much more in relative terms.

Moudakis Cartoon

Misplaced priorities are on full display in Paris for the next ten days at the climate conference known as COP-21 (“Conference of the Parties”). Joel Kotkin makes note of the hysteria in evidence among climate activists fostered by political opportunists, economic illiteracy and fraudulent climate research. Of course, climate alarmism offers handsome rewards for politician-cronyists and rent-seeking corporatists. With that seemingly in mind, President Barack Obama is playing the role of opportunist-in-chief, claiming that climate change is the biggest threat to U.S. security while blithely asserting that the climate is responsible for the growing danger from terrorism. Here is Kotkin on such tenuous claims:

“… this reflects the growing tendency among climate change activists to promote their cause with sometimes questionable assertions. Generally level-headed accounts, such as in the Economist and in harder-edge publications like the Daily Telegraph, have demonstrated that many claims of climate change activists have already been disproven or are somewhat exaggerated.“

“Somewhat exaggerated” is an understatement, given the scandals that have erupted in the climate research community, the miserable predictive record of carbon forcing models, and the questionable practices employed by NASA and NOAA researchers in adjusting surface temperature data (see below for links). When it comes to climate activism, the Orwellian aspect of Groupthink is palpable:

“Rather than address possible shortcomings in their models, climate change activists increasingly tend to discredit critics as dishonest and tools of the oil companies. There is even a move to subject skeptics to criminal prosecution for deceiving the public.“

This is thoroughly contrary to the spirit of scientific inquiry, to say nothing of free speech. As if to parody their questionable approach to an issue of science, climate-change devotees have come out in full force to attack the excellent Matt Ridley, a sure sign that they find his message threatening to the power of their mantra. Ridley and Benny Peiser have an op-ed in the Wall Street Journal this week entitled “Your Complete Guide to the Climate Debate” (should be ungated for now). The authors discuss the weakness of the scientific case for anthropomorphic global warming (AGW); the fact that they use findings of the Intergovernmental Panel on Climate Change (IPCC) to make this critique must be particularly galling to the alarmists. Ridley and Peisner cover the correspondingly flimsy case for draconian environmental policies to deal with the perceived threat of AGW. Also, they emphasize the regressive nature of the demands made by the environmental left, who are either ignorant or unfazed by the following truths:

“… there are a billion people with no grid electricity whose lives could be radically improved—and whose ability to cope with the effects of weather and climate change could be greatly enhanced—with the access to the concentrated power of coal, gas or oil that the rich world enjoys. Aid for such projects has already been constrained by Western institutions in the interest of not putting the climate at risk. So climate policy is hurting the poor.“

Finally, Ridley and Peisner explain the economic incentives that are likely to undermine any meaningful international agreement in Paris. Less developed countries have been asked to reduce their carbon emissions, which they can ill afford, and to agree to a verification framework. Those parties might agree if they view the framework as sufficiently easy to game (and it will be), and if they are compensated handsomely by the developed world. The latter will represent an insurmountable political challenge for the U.S. and other developed countries, who are already attempting to promulgate costly new restrictions on carbon emissions.

“Concerned about the loss of industrial competitiveness, the Obama administration is demanding an international transparency-and-review mechanism that can verify whether voluntary pledges are met by all countries. Developing countries, however, oppose any outside body reviewing their energy and industrial activities and carbon-dioxide emissions on the grounds that such efforts would violate their sovereignty.

… China, India and the ‘Like-Minded Developing Countries’ group are countering Western pressure by demanding a legally binding compensation package of $100 billion a year of dedicated climate funds, as promised by President Obama at the U.N. climate conference in Copenhagen in 2009.

However, developing nations are only too aware that the $100 billion per annum funding pledge is never going to materialize, not least because the U.S. Congress would never agree to such an astronomical wealth transfer. This failure to deliver is inevitable, but it will give developing nations the perfect excuse not to comply with their own national pledges.“

These conflicting positions may mean that the strongest point of accord at the Paris conference will be to meet again down the road.

“Expect an agreement that is sufficiently vague and noncommittal for all countries to sign and claim victory. Such an agreement will also have to camouflage deep and unbridgeable divisions while ensuring that all countries are liberated from legally binding targets a la Kyoto.“

This morning, an apparently sleepy and deluded President Obama spoke at the Paris conference before heading back to the U.S. He insisted again that the agreement he expects to come out of Paris will be a “powerful rebuke” to terrorists. Yeah, that’ll show ’em! Even a feeble agreement will be trumpeted as a great victory by the conference parties; Obama and the Left will attempt to wield it as a political cudgel, a brave accomplishment if it succeeds in any way, and a vehicle for blame if it is blocked by the principled opponents of climate alarmism. The media will play along without considering scientific evidence running contrary to the hysterical global warming narrative. Meanwhile, the frailty of the agreement will represent something of a win for humanity.

Climate Negotiators To Discuss Economic Cannibalism

There is virtually zero chance that the coming round of international talks on climate change will produce a substantive agreement. The United Nations’ 21st Conference of the Parties (COP 21) on Climate Change is scheduled will be held in Paris, France from November 30 to December 11. The failure of earlier conferences to produce a meaningful pact informs us of the low odds of success: this conference, like the others, will be unproductive in any real sense. As in the past, there are severely conflicting objectives among the parties. Oren Cass explains the reasons in a recent report from the Manhattan Institute, “Leading Nowhere: The Futility and Farce of Global Climate Negotiations“:

“… there is no plausible path to an agreement premised on collective action or compensation: developing nations that must bear the brunt of emissions reductions in any successful scenario cannot achieve those reductions while pursuing rapid economic growth; developed nations cannot sufficiently compensate developing ones for forgoing such growth. Evidence from recent negotiations, as well as preparations for the next round of talks, reinforces this conclusion. … [A] third path to an agreement—coercion—has received little attention. No group of nations appears prepared to employ the approach and risk subsequent conflict.“

Even the President of the Foundation For a Positive Planet asks, “What Purpose Does COP 21 Still Serve?”

It’s worth emphasizing that the the developing world will account for 79% of the world’s cumulative carbon emissions by 2100 under a moderate growth scenario developed by the Intergovernmental Panel on Climate Change (IPCC). Cass points out that even if the world’s developed countries ceased all carbon emissions immediately, developing countries would face an impossible task in cutting emissions sufficiently to stay within the IPCC’s estimated “safe carbon budget” for the globe. The best that can be said is that the IPCC might be trying to set the bar high for negotiators, although that would make claims of success at COP 21 difficult. Perhaps that’s fine for activists, because they’ll have an ongoing “crisis” to meet their insatiable need for doomsaying.

Relatively impoverished developing countries will not wish to sacrifice their own economic growth at the altar of climate worship without compensation. In fact, redistribution might be a better description than compensation, which just might be the real point of the conference for many developing countries. Promises of carbon reductions are not guarantees in any case. Future compensation to the developing world, if any, should be contingent on actual results. But no matter the outcome of the negotiations, the importance of cheap words will be exaggerated.

The magnitude of any negotiated reductions in carbon emissions will be inadequate to put much of a dent in actual, climate outcomes, but they will be costly. Writing in the Wall Street Journal, Bjorn Lomborg describes estimates of lost global output due to proposed carbon cutbacks of $1 – $2 trillion each year by 2030 and beyond. That’s roughly 1% – 2% of projected real GDP. of course, there is considerable uncertainty around those estimates and even more around the magnitude of the possible climate effects. Lomborg estimates a best-case outcome amounting to a reduction in global temperatures of a fraction of a degree Fahrenheit. That difference could easily be swamped by natural climate effects. Worth it?

Indeed, imposed limits on economic growth will compound the difficulty of improving carbon efficiency and would consign third-world populations to an impoverished existence in both economic and environmental terms.

President Obama has promised significant carbon reduction in the U.S. However, the COP 21 negotiations do not fall under the “fast-track” authority that Obama was granted by Congress last May over trade agreements. Instead, the hoped-for climate agreement has been characterized as an update to a 1992 treaty to avoid a Congressional ratification process. In addition, Obama has already issued executive orders to push forward the climate measures he has promised to other parties to COP 21. So much for the separation of powers. However, a number of states are not taking it lying down. In fact, 24 states and others have filed suit against the new regulations, asking the D.C. Circuit Court to stay the regulatory plan while the case moves through the courts.

Anthropomorphic global warming (AGW) has been a preoccupation of the alarmist left since the late 20th century, when surface temperatures trended upward for a few decades. Climate change (10 posts at this link), on the other hand, is and always has been a fact of life, but the satellite temperature record has been trendless since the mid 1990s, while the alarmist climate models have predicted significant warming. Beyond the predictions themselves, there is little to suggest that some warming would constitute a disaster for mankind, and perhaps it would be a boon.

Nevertheless, even if we stipulate that carbon emissions must be reduced, there is an innocuous alternative to government regulatory intrusions and taxes for achieving that end: the enhanced carbon efficiency and technological innovation that economic growth makes possible. One of my favorite bloggers, economist Don Boudreaux, explains the logic of this alternative in this excellent post: “Economic Growth and Pollution Abatement“. He takes a “broad view” of pollution, not simply carbon or other industrial pollutants, because there are many forms of “natural” pollution that inflict greater misery than carbon ever will. With that in mind, Boudreaux appeals to the following relationships between pollution and income (or production):

Pollution Chart

Here is his description of the chart:

“The red curve in the nearby graph is the standard environmental Kuznets curve. This red curve shows the relationship between per-capita income and industrial pollutants. The blue curve shows the relationship between per-capita income and what we might, as a short-hand, call “naturally occurring pollutants” (that is, filth such as bacteria, mud on indoor floors, and rodent and bird droppings from the ceiling of one’s home).“

The red curve implies that a cleaner environment is a “luxury good”. I would also point out that the ascent of the red line at relatively low income levels will be muted by the substitution of cleaner fuels for primitive forms such as dung- and wood-burning, often burned indoors. This is consistent with Boudreaux’s point, though in a way that is not directly addressed by his explanation of the chart:

“… my hypothesis – which I believe is borne out by the historical record – is that people almost immediately start to consume greater cleanliness as they become wealthier.“

The combination of the two lines in the chart shows that economic growth is not unambiguously “bad” for the environment. It has certainly proven to be a good thing in terms of human health and welfare. As a consequence, developing countries should not be so foolish as to sacrifice economic growth for immediate carbon reductions. On the other hand, they may well make “promises” in exchange for massive compensation.

Neither should the world be singularly focused on immediate carbon reductions, because economic growth will be accompanied by improvements in carbon efficiency and the development of technologies far superior to today’s wasteful renewables. The activists attending COP 21 hope to improve the world, but they would saddle humanity with unnecessary burdens. I pity the denizens of countries whose leaders force costly authoritarian energy policies upon them in an effort to set, or comply with, a radical agenda. Oh, wait, that might be us! But I am optimistic that any agreement reached in Paris, if there is any, won’t hold or won’t matter.

“Devastating release of carbon emissions has ancient Syrian city of Palmyra now under ISIS control“.

Tongue in cheek, of course, from Twitchy. But maybe not so much: in his commencement address to graduates of the Coast Guard Academy this week, President Obama took the laughable positions that global warming was a) contributing to unrest in the middle east; and b) is an immediate threat to U.S. national security. He bases this immediacy on climate models that have been not just wrong, but extremely wrong, as well as a series of related distortions. These are rebutted one-by-one in “Does the ‘leader’ of the free world really know so little about climate?” by Christopher Monckton.

Global warming activists are so fond of their scare stories that they just can’t stop, despite a long track record of predictive lousiness. But their sins extend beyond bad predictions to bad data itself. One scare story has the world’s sea-ice extent shrinking drastically, especially in the Arctic. Now, NASA has come clean on this point: updated data from the agency shows that sea ice has not contracted over the past 35 years, it has actually increased somewhat. The data is charted here. From the Forbes link:

“Updated data from NASA satellite instruments reveal the Earth’s polar ice caps have not receded at all since the satellite instruments began measuring the ice caps in 1979. Since the end of 2012, moreover, total polar ice extent has largely remained above the post-1979 average.“

To this day I see posts suggesting that the polar ice caps in a fast melt and that polar bears are increasingly endangered. Both assertions are simply not true. The global polar bear population has recovered from the lows of 50 years ago and is stable. Most regional populations are stable, some are in decline, and some are growing.

Another claim is that that Antarctic ice is melting. In fact, the ice extent around Antarctica is at record levels. There is massive volcanic activity under an area in western Antarctica, where some ice loss has been recorded. That is hardly proof of a man-made carbon-induced effect. Along with the fictitious ice melt, alarming predictions of increased sea levels are often heard. But sea level increases in the past 100 years are minuscule relative to more distant historical episodes.

President Obama is casting about for a legacy other than failure. His signature health care plan is in jeopardy on several fronts, his foreign policy is bumbling (even to a non-interventionist), his economic legacy is weak at best, his legacy of cronyism is legend, and his legacy of debt is gargantuan. As to Obama’s record on the environment, he just might be a slave to defunct climate researchers.

High-Speed Third Rail For Taxpayers

Public boondoggles come in many forms, including sports stadiums and entertainment venues, convention centers, local trolly lines, light rail, superhighways, “gold-plated” public offices, and even subsidies for politically-favored (as opposed to market-favored) industries. Anything involving “infrastructure” has an almost perverse  political appeal. The many varieties of boondoggles have much in common from a public finance perspective: ultimately, they are almost always funded by taxpayers; when they confer benefits to private parties (and they usually do), they are underpriced to those users. Taxpayers are often lucky if these projects cover their operating costs, let alone capital costs, via direct revenue generation. Taxpayers are usually on the hook for the bonds. Pure public benefits might offer some justication for this burden, but those cited by project proponents are often unconvincing on that basis. Let’s face it: projects are seldom evaluated against something approximating the true opportunity costs faced by the public or taxpayers.

A prominent example of such a project that seems to capture the political imagination is high-speed rail (HSR). My friend John Crawford emailed the following link: “Doing the math on California’s bullet train fares“. John provided this summary:

“Not surprisingly, today’s fare estimate has risen 72% over the estimate that was cited during planning. That’s telling but probably not surprising to anyone, even those that tried to change opinions by citing the $50 fare. What I think is most interesting follows.

CA-HSR price of 86 is about 20c/mile. Comparable prices are 22c for a Chinese train that everybody agrees to be subsidized, 54c for a French train that is profitable and 50c for the Amtrak corridor on the East coast, which is probably profitable; 46c in Germany. Somehow, they think they can do what nobody else in the world can do…profit at 20c/mile.“

The California authority is either spectacularly arrogant or stupid. Probably the former, because they are doing what self-interested bureaucrats and politicians always do. They want the project to get done, thus creating an empire, kicking a can-full of fare increases and taxpayer liabilities down the road, beyond the time when anyone will hold them accountable for the malinvestment. But the true extent of the malinvestment will never be obvious, because the counter-factual will remain in the unseen world of lost opportunity.

Something I find exasperating about articles like this are references to “profitability”, as in “… state officials say the system will quickly become profitable“, when the meaning is not actual profitability. My friend John did it too, but I forgive him because he knew the score, and because he’ll forgive me for being a pedant (I hope). But this is important! What the California officials mean by “profitability” (and it is a misuse of the term) is fare revenue in excess of operating costs. The latter do not include initial capital costs, so these officials are not making claims about actual profitability. Profitability means that revenue exceeds ALL costs, including capital costs. Many observers consider the California authority’s estimates of operating costs to be suspect, so it’s not even clear that revenue will cover the future costs of capital replacement, let alone the initial installation costs. Construction and planning costs are expected to be $68 billion for Phase 1 only, and you can safely bet on significant additional overruns by the projected completion of Phase 1 in 2029.

Fares calibrated to cover operating costs are not defensible in terms of long-run marginal cost pricing. While an incremental rider does not cause the capital cost of the system to increase in the short run, incremental riders absolutely do have an impact on long-run capital costs. In any case, there are many incremental riders at start-up. The long run is now. Yet, like many public projects, the burden of uncovered costs is justified in terms of other benefits of a supposedly public nature. Here is a vague description of such benefits from the CA HSR Authority:

“California high-speed rail will connect the mega-regions of the state, contribute to economic development and a cleaner environment, create jobs and preserve agricultural and protected lands.“

Let’s take these one at a time:

  • connecting “mega-regions”, if that is a real benefit of HSR relative to alternative modes of transportation, will largely accrue to riders, not the general public.
  • Economic development benefits are possible along the route or near stations, but that is hardly a pure public benefit, and it is likely to come at the expense of development elsewhere.
  • The trains will be powered, at least in part, by energy from fossil fuels. If HSR produces less carbon than equivalent airplanes, autos and other alternatives, that might represent a pure public benefit (according to the carbonphobic), but this is a costly way to achieve a minor reduction in carbon emissions. It is of value only to the extent that HSR brings real substitution away from other, higher carbon modes.
  • Construction jobs are part of the cost of the project, but this is a common ploy and very handy way to sell the project. Gains for the workers are certainly not a pure public benefit. To paraphrase Bastiat, calling construction jobs from malinvested capital a “public benefit” is like calling a broken window beneficial because it provides work for the glazier.
  • As for preserving agricultural and public lands, I do not believe that HSR will make much of a dent in future, land-gobbling highway construction (and if it did, it would offset those vaunted HSR job gains).

The public should always view large public projects like HSR with skepticism and insist that private benefits should be paid privately. There are always alternative uses of taxpayer funds, including the possibility that taxpayers should keep them. Too many public projects become funding disasters. In many cases, private parties would not be willing to buy the facilities for more than 10 cents on the dollar.of original cost.  Without access to tax revenue, only a low purchase price would allow them to operate at a profit.

At the national level, this week’s tragic Amtrak crash near Philadelphia was the context for misguided calls to provide additional funding to the rail service. Sean Davis in The Federalist has a more logical proposal, even if it is a bit radical: not only should Amtrak be privatized, its assets should be given away! And how could anyone reach such a conclusion?

“Amtrak lost nearly $1.3 billion in 2013. Since its creation, Amtrak has racked up over $31 billion in accumulated losses. And every penny of those losses has been covered by federal taxpayers.

… Hand over the entire enterprise to whichever rail company wants it. ‘But that’s crazy!’ you might say. ‘Giving it away for free makes no cents [sic]!’

Well, neither does keeping it on the taxpayers’ books. The status quo costs taxpayers at least a billion dollars each year.“

Davis makes a fair point, though a give-away might attract multiple takers. Ultimately, bidding just might be necessary! Or, perhaps it would be necessary to PAY a private rail operator to take Amtrak off the federal government’s hands. A fairly high payment would still be worthwhile to taxpayers.

Randall O’Toole provides this excellent discussion of privatizing transit in a video  of approximately 17 minutes. He discusses trends in ridership, the inefficiencies inherent in public transportation systems, and compares various market structures and types of private transportation systems, including private intercity buses (Megabus). He also addresses concerns that private transportation systems will not meet the needs of the poor by proposing the substitution of “transit stamps” for the huge subsidies currently paid into transportation bureaucracies.

Cut CO2, But What About The Environment?

Reducing CO2 emissions can carry a high cost to the environment, as explained by The Climate Skeptic.  The tradeoff is all too real because the resources available for mitigating environmental damage are scarce. The simple economics of pollution abatement suggest that small reductions in CO2 are the best that can be achieved even as opportunities for large reductions in more dangerous pollutants are foregone. From The Skeptic:

“Coal plants produce a lot of CO2, but without the aid of modern scrubbers and such, they also produce SOx, NOx, particulates matter and all the other crap you see in the Beijing air. The problem is that the CO2 production from a coal plant takes as much as 10-100x more money to eliminate than it takes to eliminate all the other bad stuff. … Thus the same money needed to make an only incremental change in CO2 output would make an enormous change in the breath-ability of air in Chinese cities.”

In the developing world, the reductions  in CO2 emissions might also mean the sacrifice of gains in the standard of living and public health. To make matters worse, the actual benefits of reducing CO2 emissions are highly questionable: a warmer climate, should it come to pass, is unlikely to be any catastrophe, and in fact it could produce substantial net benefits for humanity.

Along the same lines, President Obama’s recent call for reduced CO2 emissions is described by Alan Caruba as a “Cruel and Costly Climate Hoax“. The climate panic has been inflamed by a community of climate researchers who have perpetrated fraud in the management of temperature data and corrupted their field’s peer review process,  and who continue to rely on climate models with terrible track records. After roughly 25 years of warming temperatures had dispelled fears of a new ice age, these researchers have recognized the latest 18-year pause in that trend with reluctance, marshaling a variety of excuses for the poor performance of their models: the ocean has acted as a heat sink (false), a series of small volcanic eruptions have caused solar energy to be reflected back into space (speculative at best, and without data prior to the year 2000 to back up the claim), or my favorite… that Chinese carbon emissions have limited solar radiation! How ironic is that?

Reductions in carbon emissions are resource intensive. Those resources have alternative uses that are too valuable to make a cavalier sacrifice. Opportunities for other kinds of environmental enhancements, improvements in public health, and better living standards should carry the day, not carbon reductions.
