We all share Planet Earth as our home, so there’s a strong sense in which it qualifies as a “commons”. That’s one sensible premise of a new paper entitled “The planetary commons: A new paradigm for safeguarding Earth-regulating systems in the Anthropocene”. The title is a long way of saying that the authors desire broad-based environmental regulation, and that’s what ultimately comes across.

First, a preliminary issue: many resources qualify as commons in the very broadest sense, yet free societies have learned over time that many resources are used much more productively when property rights are assigned to individuals. For example, modern agriculture owes much to defining exclusive property rights to land so that conflicting interests don’t have to compete (e.g,, the farmer and the cowman). Federal land is treated as a commons, however. There is a rich history on the establishment of property rights, but within limits, the legal framework in place can define whether a resource is treated as a commons, a club good, or private property. The point here is that there are substantial economic advantages to preserving strong property rights, rather than treating all resources as communal.

The authors of the planetary commons (PC) paper present a rough sketch for governance over use of the planet’s resources, given their belief that a planetary crisis is unfolding before our eyes. The paper has two main thrusts as I see it. One is to broadly redefine virtually all physical resources as common pool interests because their use, in the authors’ view, may entail some degree of external cost involving degradation of the biosphere. The second is to propose centralized, “planetary” rule-making over the amounts and ways in which those resources are used.

It’s an Opinion Piece

The PC paper is billed as the work product of a “collaborative team of 22 leading international researchers”. This group includes four attorneys (one of whom was a lead author) and one philosopher. Climate impact researchers are represented, who undoubtedly helped shape assumptions about climate change and its causes that drive the PC’s theses. (More on those assumptions in a section below.) There are a few social scientists of various stripes among the credited authors, one meteorologist, and a few “sustainability”, “resilience”, and health researchers. It’s quite a collection of signees, er… “research collaborators”.

Grabby Interventionists

The reasoning underlying a “planetary commons” (PC) is that the planet’s biosphere qualifies as a commons. The biosphere must include virtually any public good like air and sunshine, any common good like waterways, or any private good or club good. After all, any object can play host to tiny microbes regardless of ownership status. So the PC authors characterization of the planet’s biosphere as a commons is quite broad in terms of conventional notions of resource attributes.

We usually think of spillover or external costs as arising from some use of a private resource that imposes costs on others, such as air or water pollution. However, mere survival requires that mankind exploit both public and non-public resources, acts that can always be said to impact the biosphere in some way. Efforts to secure shelter, food, and water all impinge on the earth’s resources. To some extent, mankind must use and shape the biosphere to succeed, and it’s our natural prerogative to do so, just like any other creature in the food chain.

Even if we are to accept the PC paper’s premise that the entire biosphere should be treated is a commons, most spillovers are de minimus. From a public policy perspective, it makes little sense to attempt to govern over such minor externalities. Monitoring behavior would be costly, if not impossible, at such an atomistic level. Instead, free and civil societies rely on a high degree of self-governance and informal enforcement of ethical standards to keep small harms to a minimum.

Unfortunately, the identification and quantification of meaningful spillover costs is not always clear-cut. This has led to an increasingly complex regulatory environment, an increasingly litigious business environment, and efforts by policymakers to manage the detailed inputs and outputs of the industrial economy.

All of that is costly in its own right, especially because the activities giving rise to those spillovers often enable large welfare enhancements. Regulators and planners face great difficulties in estimating the costs and benefits of various “correctives”. The very undertaking creates risk that often exceeds the cost of the original spillover. Nevertheless, the PC paper expands on the murkiest aspects of spillover governance by including “… all critical biophysical Earth-regulating systems and their functions, irrespective of where they are located…” as part of a commons requiring “… additional governance arrangements….”

Adoption of the PC framework would authorize global interventions (and ultimately local interventions, including surveillance) on a massive scale based on guesswork by bureaucrats regarding the evolution of the biosphere.

Ostrom Upside Down

Not only would the PC framework represent an expansion of the grounds for intervention by public authorities, it seeks to establish international authority for intervention into public and private affairs within sovereign states. The authors attempt to rationalize such far-reaching intrusions in a rather curious way:

“Drawing on the legacy of Elinor Ostrom’s foundational research, which validated the need for and effectiveness of polycentric approaches to commons governance (e.g., ref. 35, p. 528, ref. 36, p. 1910), we propose that a nested Earth system governance approach be followed, which will entail the creation of additional governance arrangements for those planetary commons that are not yet adequately governed.”

Anyone having a passing familiarity with Elinor Ostrom’s work knows that she focused on the identification of collaborative solutions to common goods problems. She studied voluntary and often strictly private efforts among groups or communities to conserve common pool resources, as opposed to state-imposed solutions. Ostrom accepted assigned rights and pricing solutions to managing common resources, but she counseled against sole reliance on market-based tools.

Surely the PC authors know they aren’t exactly channeling Ostrom:

“An earth system governance approach will require an overarching global institution that is responsible for the entire Earth system, built around high-level principles and broad oversight and reporting provisions. This institution would serve as a universal point of aggregation for the governance of individual planetary commons, where oversight and monitoring of all commons come together, including annual reporting on the state of the planetary commons.”

Polycentricity was used by Ostrom to describe the involvement of different, overlapping “centers of authority”, such as individual consumers and producers, cooperatives formed among consumers and producers, other community organizations, local jurisdictions, and even state or federal regulators. Some of these centers of authority supersede others in various ways. For example, solutions developed by cooperatives or lower centers of authority must align with the legal framework within various government jurisdictions. However, as David Henderson has noted, Ostrom observed that management of pooled resources at lower levels of authority was generally superior to centralized control. Henderson quotes Ostrom and a co-author on this point:

“When users are genuinely engaged in decisions regarding rules affecting their use, the likelihood of them following the rules and monitoring others is much greater than when an authority simply imposes rules.”

The authors of the PC have something else in mind, and they bastardize the spirit of Ostrom’s legacy in the process. For example, the next sentence is critical for understanding the authors’ intent:

“If excessive emissions and harmful activities in some countries affect planetary commons in other areas—for example, the melting of polar ice—strong political and legal restrictions for such localized activities would be needed.”

Of course, there are obvious difficulties in measuring impacts of various actions on polar ice, assigning responsibility, and determining the appropriate “restrictions”. But in essence, the PC paper advocates for a top-down model of governance. Polycentrism is thus reduced to “you do as we say”, which is not in the spirit of Ostrom’s research.

Planetary Governance

Transcending national sovereignty on questions of the biosphere is key to the authors’ ambitions. At a bare minimum, the authors desire legally-binding commitments to international agreements on environmental governance, unlike the unenforceable promises made for the Paris Climate Accords:

“At present, the United Nations General Assembly, or a more specialized body mandated by the Assembly, could be the starting point for such an overarching body, even though the General Assembly, with its state-based approach that grants equal voting rights to both large countries and micronations, represents outdated traditions of an old European political order.”

But the votes of various “micronations” count for zilch when it comes to real “claims” on the resources of other sovereign nations! Otherwise, there is nothing “voluntary” about the regime proposed in the PC paper.

“A challenge for such regimes is to duly adapt and adjust notions of state sovereignty and self-determination, and to define obligations and reciprocal support and compensation schemes to ensure protection of the Earth system, while including comprehensive stewardship obligations and mandates aimed at protecting Earth-regulating systems in a just and inclusive way.”

So there! The way forward is to adopt the broadest possible definition of market failure and global regulation of any and all private activity touching on nature in any way. And note here a similarity to the Paris Accords: achieving commitments would fall to national governments whose elites often demonstrate a preference for top-down solutions.

Ah Yes, Redistribution

It should be apparent by now that the PC paper follows a now well-established tradition in multi-national climate “negotiations” to serve as subterfuge for redistribution (which, incidentally, includes the achievement of interspecies justice):

“For instance, a more equal sharing of the burdens of climate stabilization would require significant multilateral financial and technology transfers in order not to harm the poorest globally (116).”

The authors insist that participation in this governance would be “voluntary”, but the following sentence seems inconsistent with that assurance:

“… considering that any move to strengthen planetary commons governance would likely be voluntarily entered into, the burdens of conservation must be shared fairly (115).”

Wait, what? “Voluntary” at what level? Who defines “fairness”? The authors approvingly offer this paraphrase of the words of Brazilian President Lula da Silva,

“… who affirmed the Amazon rainforest as a collective responsibility which Brazil is committed to protect on behalf of all citizens around the world, and that deserves and justifies compensation from other nations (117).”

Let Them Eat Cake

Furthermore, PC would require de-growth and so-called “sufficiency” for thee (i.e., be happy with less), if not for those who’ll design and administer the regime.

“… new principles that align with novel Anthropocene dynamics and that could reverse the path-dependent course of current governance. These new principles are captured under a new legal paradigm designed for the Anthropocene called earth system law and include, among others, the principles of differentiated degrowth and sufficiency, the principle of interconnectivity, and a new planetary ethic (e.g., principle of ecological sustainability) (134).”

If we’re to take the PC super-regulators at their word, the regulatory regime would impinge on fertility decisions as well. Just who might we trust to govern humanity thusly? If we’re wise enough to apply the Munger Test, we wouldn’t grant that kind of power to our worst enemy!

Global Warmism

The underlying premise of the PC proposal is that a global crisis is now unfolding before our eyes: anthropomorphic global warming (AGW). The authors maintain that emissions of carbon dioxide are the cause of rising temperatures, rapidly rising sea levels, more violent weather, and other imminent disasters.

“It is now well established that human actions have pushed the Earth outside of the window of favorable environmental conditions experienced during the Holocene…”

“Earth system science now shows that there are biophysical limits to what existing organized human political, economic, and other social systems can appropriate from the planet.”

For a variety of reasons, both of these claims are more dubious than one might suppose based on popular narratives. As for the second of these, mankind’s limitless capacity for innovation is a more powerful force for sustainability than the authors would seem to allow. On the first claim, it’s important to note that the PC paper’s forebodings are primarily based on modeled, prospective outcomes, not historical data. The models are drastically oversimplified representations of the earth’s climate dynamics driven by exogenous carbon forcing assumptions. Their outputs have proven to be highly unreliable, overestimating warming trends almost without exception. These models exaggerate climate sensitivity to carbon forcings, and they largely ignore powerful natural forcings such as variations in solar irradiance, geological heating, and even geological carbon forcings. The models are also notorious for their inadequate treatment of feedback effects from cloud cover. Their predictions of key variables like water vapor are wildly in error.

The measurement of the so-called “global temperature” is itself subject to tremendous uncertainty. Weather stations come and go. They are distributed very unevenly across land masses, and measurement at sea is even sketchier. Averaging all these temperatures would be problematic even if there were no other issues… but there are. Individual stations are often sited poorly, including distortions from heat island effects. Aging of equipment creates a systematic upward bias, but correcting for that bias (via so-called homogenization) causes a “cooling the past” bias. It’s also instructive to note that the increase in global temperature from pre-industrial times actually began about 80 years prior to the onset of more intense carbon emissions in the 20th century.

Climate alarmists often speak in terms of temperature anomalies, rather than temperature levels. In other words, to what extent do temperatures differ from long-term averages? The magnitude of these anomalies, using the past several decades as a base, tend to be anywhere from zero degrees to well above one degree Celsius, depending on the year. Relative to temperature levels, the anomalies are a small fraction. Given the uncertainty in temperature levels, the anomalies themselves are dwarfed by the noise in the original series!

Pick Your Own Tipping Point

It seems that “tipping point” scares are heavily in vogue at the moment, and the PC proposal asks us to quaff deeply of these narratives. Everything is said to be at a tipping point into irrecoverable disaster that can be forestalled only by reforms to mankind’s unsustainable ways. To speak of the possibility of other causal forces would be a sacrilege. There are supposed tipping points for the global climate itself as well as tipping points for the polar ice sheets, the world’s forests, sea levels and coastal environments, severe weather, and wildlife populations. But none of this is based on objective science.

For example, the 1.5 degree limit on global warming is a wholly arbitrary figure invented by the IPCC for the Paris Climate Accords, yet the authors of the PC proposal would have us believe that it was some sort of scientific determination. And it does not represent a tipping point. Cliff Mass explains that climate models do not behave as if irreversible tipping points exist.

Consider also that there has been absolutely no increase in the frequency or intensity of severe weather.

Likewise, the rise of sea levels has not accelerated from prior trends, so it has nothing to do with carbon forcing.

One thing carbon forcings have accomplished is a significant greening of the planet, which if anything bodes well for the biosphere

What about the disappearance of the polar ice sheets? On this point, Cliff Mass quotes Chapter 3 of the IPCC’s Special Report on the implications of 1.5C or more warming:

“there is little evidence for a tipping point in the transition from perennial to seasonal ice cover. No evidence has been found for irreversibility or tipping points, suggesting that year-round sea ice will return given a suitable climate.”

The PC paper also attempts to connect global warming to increases in forest fires, but that’s incorrect: there has been no increasing trend in forest fires or annual burned acreage. If anything, trends in measures of forest fire activity have been negative over the past 80 years.

Concluding Thoughts

The alarmist propaganda contained in the PC proposal is intended to convince opinion leaders and the public that they’d better get on board with draconian and coercive steps to curtail economic activity. They appeal to the sense of virtue that must always accompany consent to authoritarian action, and that means vouching for sacrifice in the interests of environmental and climate equity. All the while, the authors hide behind a misleading version of Elinor Ostrom’s insights into the voluntary and cooperative husbandry of common pool resources.

One day we’ll be able to produce enough carbon-free energy to accommodate high standards of living worldwide and growth beyond that point. In fact, we already possess the technological know-how to substantially reduce our reliance on fossil fuels, but we lack the political will to avail ourselves of nuclear energy. With any luck, that will soften with installations of modular nuclear units.

Ultimately, we’ll see advances in fusion technology, beamed non-intermittent solar power from orbital collection platforms, advances in geothermal power, and effective carbon capture. Developing these technologies and implementing them at global scales will require massive investments that can be made possible only through economic growth, even if that means additional carbon emissions in the interim. We must unleash the private sector to conduct research and development without the meddling and clumsy efforts at top-down planning that typify governmental efforts (including an end to mandates, subsidies, and taxes). We must also reject ill-advised attempts at geoengineered cooling that are seemingly flying under the regulatory radar. Meanwhile, let’s save ourselves a lot of trouble by dismissing the interventionists in the planetary commons crowd.

Tis the Season of Peak Climate Propaganda

It happens every summer! It’s been hot, and the news media and professional grifters in the anti-carbon climate-change establishment want us to panic about it. Granted, the weather really was quite hot for several weeks in July across parts of the U.S., Europe, and elsewhere, but it’s cooled off considerably since then, especially in my neck of the woods.

July is typically the warmest month of the year, and July 2023 was the warmest July for the troposphere on the satellite record. (The troposphere is the lowest 13 km of the atmosphere, but that’s an average — it’s thicker toward equatorial latitudes, thinner toward the poles.) However, attribution of this summer’s heat waves to carbon-induced climate change is misplaced. What follows are a few considerations in evaluating this claim, and the lengths to which climate activists go to distort weather data and reporting.

The Biggest Greenhouse Gas

One speculative explanation for the recent heat wave has gained some traction: the eruption of the Hunga Tonga-Hunga Ha’apai volcano in the South Pacific on Jan. 15, 2022 (and see here). This underwater eruption spewed massive quantities of water vapor into the stratosphere, which encircled the globe in fairly short order. Water vapor acts as a greenhouse gas, and it is by far the most important greenhouse gas. This plume of vapor may have affected the climate with a delay, and it is not expected to dissipate for at least a couple of years. However, there are theories that the eruption might have led to some offsetting effects due to the reflective properties of water and ice in the stratosphere. See here for an interesting debate on the estimated effects of this “shock” to the atmosphere.

NASA has estimated that the Hunga Tonga eruption resulted in a 10% increase in atmospheric water vapor, while the European Space Agency puts the increase at 13%. Now, in addition to this added water vapor, we have the early effects of an El Niño event in the Pacific, which may elevate temperatures over the next couple of years.

However, the temperatures in July simply don’t justify the claim that we’re experiencing “unprecedented” warmth. The satellite records go back only to 1979, which is an especially narrow window on climatological scales. The longer record of temperatures shows earlier periods of higher temperatures, For example, U.S. surface temperature records indicate that the 1930s had periods warmer than this July. Moreover, while estimates of paleo-climate data are a matter of great dispute, there is no question that the globe has experienced warmer temperatures in the past, with an ice-free Arctic.

So, was July 3 really the hottest day in history? No way, and the worst part of this warm spell wasn’t even the warmth. Rather, it was the attempts to make weather a political matter, as if public policymakers possess some kind of control knob over weather phenomena, or as if we should bestow upon them dictatorial powers to act on their fantasy.

Longer Trends

There’s plenty of other evidence running contrary to the “hotter-than-any-time in-history” foolishness. Take a look at trends in hot and cool weather from individual U.S. weather stations over a somewhat longer time span than the satellite record. The red symbols shown on the map below mark stations reporting increases in the number of unusually hot days (heat in the 95th percentile) between 1948 – 2020, with larger symbols corresponding to greater increases in extremely hot days. The blue symbols mark stations reporting increases in the number of unusually cool days (in the 5th percentile) over the same period. The data in this chart is published by the EPA, and it is definitely not alarming.

The next chart shows the so-called Heat Wave Index produced by the EPA. Recent spikes in the index are muted relative to the Dust Bowl days of the 1930s.

Journalism or Exaggeration?

Reports of hot weather in Europe have been distorted as well, often placing more emphasis on forecasts of high temperatures than on the temperatures themselves. It’s almost as if authorities, with the aid of the news media and naive weather reporters, are determined to raise an exaggerated sense of alarm among the citizenry. Almost?

Cold 10x Deadlier Than Heat

The next chart vividly illustrates an attempt to propagandize climate misinformation. Take a look at the left side of this illustration, which appeared in the medical journal Lancet. Note the difference in the horizontal scale for heat deaths vs. cold deaths. The chart on the right side uses equivalent scales for heat vs. cold deaths. This should qualify the journal for some kind of award for mendacity, or perhaps sheer stupidity. It’s the cold that really kills, not the heat! I’m moving south!

Finding Hot Water

And here’s a take-down of some incredible water temperature propaganda. A PBS News Hour reporter has pushed claims that South Florida water temperatures reached 101 degrees this summer. The emphasis on a single reading was taken from a buoy not subject to the cooling effects of deep water circulation, and it is located where fresh water often overlays salt water, which traps heat. Data from other buoys not far away showed much lower temperatures.

Spreads Like Wildfire

Another fallacious claim we hear too often is that global warming is literally causing the world to go up in flames. The facts run contrary to these scare stories. Björn Lomborg notes the following:

“For more than two decades, satellites have recorded fires across the planet’s surface. The data are unequivocal: Since the early 2000s, when 3% of the world’s land caught fire, the area burned annually has trended downward.

“In 2022, the last year for which there are complete data, the world hit a new record-low of 2.2% burned area. Yet you’ll struggle to find that reported anywhere.”

The heavy focus by the media on this year’s wild fires in North America offers a perfect example of the media’s tendency to “cherry pick for clicks”. Africa and Europe have had little burning this year, and in North America, arson has played a conspicuous role (and see here) in the wildfires.

Distorted Measurements

Personally, I have trouble accepting claims that temperatures are any warmer now than they were in my youth, at least where I grew up. My subjective and local assessment aside, there are strong reasons to doubt the reliability and significance of trends in official temperature records. The urban heat-island effect has distorted temperatures by ever greater magnitudes, as growing metropolitan areas absorb heat readily compared to rural green space.

Furthermore, poor siting of weather stations and temperature gauges has become all too common. This includes equipment located at airports and other areas in close proximity to asphalt or concrete. This contributes to an upward bias in more recent temperature data. It’s also worth noting in this context that satellite temperature readings must be calibrated periodically to surface temperatures. If the latter are corrupted in any way, the satellite readings may be corrupted as well.

“Adjusting” the Past

Official historical records also include a variety of “adjustments” to temperature data that raise concerns. Ostensibly, these adjustments are justified by an interest in maintaining a consistent historical record. Changes in equipment or it’s exact location can create discontinuities, for example. Unfortunately, the adjustments appear to have had a systematic tendency to “cool the past” relative to more recent data. This reinforcement of the warming trend over the past few decades is suspicious, to say the least. It does very little to build confidence in the agencies responsible for these records.

Conclusion

The hot temperatures in July brought the usual deluge of propaganda, including distortions in the reporting of weather phenomena. And we hear increasing calls to force transition to EVs (which are powered mostly by fossil-fuel electric plants), subsidize intermittent renewable power sources, and to end the use of air conditioning and gas stoves. Yet these coercive measures would do nothing to prevent summer heat or climate change generally. Water vapor represents 95% of greenhouse gases, and the huge vapor shock from the Hunga Tonga eruption might well make us prone to warmer temperatures for at least some months to come, mixed with signals from the Pacific El Niño pattern. But these are not evidence of a man-made crisis, despite perverse cheers from those rooting for more draconian state intrusions and an end to growth, or indeed, a reversal in gains to human well being.

Economic Growth and the Real Accretion of Resources

A few weeks ago I argued that raising living standards and eliminating poverty are human imperatives, and therefore growth is an imperative. Growth is a natural process for a free and creative people, and the alternative to growth is not zero growth. The coercion necessary to “achieve” a static economic environment would invariably lead to decline. It would be impossible to maintain average living standards while attempting a coerced leveling of those standards.

People have a notion, however, that it’s impossible to sustain growth due to the planet’s finite base of resources. If that is the case, we have available a mechanism to warn us as the time of hard limits approaches, which I’ll discuss below. So far, that signal hasn’t been activated. Moreover, the claim that growth is unsustainable can be challenged on several levels, which I’ll also address.

Effective Resources

First, a word about what I mean by the “accretion of resources”. The phrase refers to growth in the total effectiveness or productive potential of known resources given the rate of discovery and improvements in extraction and production technologies. Of course, if these discoveries and efficiencies are exceeded by current use, then there is no accretion, but depletion.

So let’s say we have a particular known stock of a resource we can readily draw on, so many pounds of resource X. In addition, we might know of the existence of another equally large quantity that can’t be readily drawn upon. Those are additional known (or proved) but undeveloped reserves. They might be difficult to exploit except at high cost, but we know they exist. We’d want to get on with the business of developing those reserves for extraction if they were needed any time soon, and we might want to begin prospecting for new reserves as well. As we’ve learned over the years. discoveries of previously unknown reserves of resources can be quite large. Prospectors are willing to bet that more resources exist, and they’ll undertake the risks of exploration if the potential rewards are adequate.

All of those concepts are straightforward. However, suppose we discover ways in which resource X can be used more efficiently, making things stronger or run longer or harder with less X. If we double the efficiency with which X is used, we have doubled the effective known reserves of X and, at least theoretically, unknown reserves as well. We’d have witnessed a doubling in the years that resource X can last. This is a form of resource accretion. Improvements in extraction or purification methods are also examples. Technological leaps like this, not to mention untold small increments in the efficiency of practices, have made economic growth possible in the past and will continue to do so in the future. Our effective resources seem to keep expanding. Accretion has occurred even with respect to resources like land as the world urbanized and the efficiency of farming advanced many-fold.

Growth In Real Time

Perceptions of growth are sometimes shaped by graphic depictions that some parties find alarming, so it might be helpful to take a quick look at some growth curves. First is an oldie-but-goodie chart showing GDP per capita taken from “Statistics on World Population, GDP, and Per Capital GDP, 1- 2008 AD” by Angus Maddison of the IMF:

This shows the explosion in the value of production that occurred during and after the industrial revolution, in contrast to very slow progress before that. The point I want to make here is how dramatic growth can look on a broad but visually compressed time scale. OMG! Look what we’ve done! How can we go on like this??? Often, the crux of the limits to growth argument is that such growth seems impossible assuming that we face fixed resource limits.

In fact, we experience growth in a very “local” way with respect to the passage of time. The two charts below illustrate a difference in perspectives using a hypothetically constant annual growth rate of 2.5%. The first chart shows 200 periods of growth, while the second expands only the last 20 periods of that time frame.

There is a great difference in the way the two vertical axes are scaled, which is important, but the second chart conveys that a respectable growth rate doesn’t really feel extreme when you’re in the middle of it, or, that is, in real time. It can look very extreme at the end of a long interval, depending on how severely the time axis is compressed. That’s not to discount the reality of much larger levels of activity (the vertical axes) and demands for resources as time goes on. However, those levels, and growth from those levels, is not at all alarming if our ability to achieve them has kept pace. So how can we know when we’re approaching a point at which resource limits will make it impossible to achieve those levels of activity? Market prices are the key signals, and they are the key to resource accretion.

Market Signals Light the Way

The market price is the best gauge of the scarcity of a resource. When resources become especially scarce, higher prices tell us so. That leads to conservation, which obviously extends the availability of those resources. Prices also function as an incentive for sellers to exploit new or harder-to-reach stores of a resource. That kind of resource accretion is one of the lessens the oil market has taught us again and again: oil exploration and known reserves tend to expand as the price rises, such that the prospect of oil depletion moves out to ever more distant horizons. There are certain minerals, elements, or isotopes (tritium?) that seem to be quite rare on Earth, but our ability to find them or extract them often improves with time. Space mining, which would vastly reduce the scarcity of resources like platinum, iron, nickel, cobalt, and many others, may become a reality in the near future. Interestingly, much of that activity could be in private hands. Space mining would lead to resource accretion on a whole new scale, and if we aspire to be a “grabby” civilization, it is a logical next step. So let’s go grab an asteroid!

When a price spikes due to greater scarcity, opportunities for substitution, exploration, and new efficiencies arise because the higher price justifies the cost of exploiting them. In addition to more difficult or costly extraction, a higher price encourages the use of close and even novel substitutes that may involve new technologies. In turn, that substitution reduces the relative scarcity of the original resource in question. And finally, back to conservation, users respond to price increases by finding their own innovative efficiencies in how a resource is utilized. The price response to scarcity is a channel through which much technological progress is encouraged.

While our earth-bound resources or even our star-system’s resources are finite, their effective quantity is highly flexible. Their potential at any time depends on our stage of discovery and the state of technology. Human ingenuity is a marvel at stretching the effective quantity of resources, and the greatest gains always occur when market forces are unleashed.

Thus, we see that prices, markets, and capitalism itself enable rational and sustainable responses to scarcity. Yet too often we hear claims that capitalism must be destroyed in order to save humanity. In fact, capitalism itself is the one system of social organization capable of achieving resource accretion, sustained growth, and lifting mankind from poverty. In fact, growth might well be an insurmountable problem without the dynamic energies of capitalism. Government planners are incapable of gathering and processing the vast information that markets process each and every day. Planners must substitute their own weak judgements, which prove flawed again and again.

Scarcity of the Commons

The environmental Left is quick to marshal a different kind of limits-to-growth argument. This one has to do with the scarcity of non-priced common resources and their overuse in production. For example, if a certain activity degrades the environment and those costs are not internalized by producers, they will tend to produce “too much”, leading to some degree of deterioration in human living conditions or the natural quality of the environment. In that case, we might not notice the limits to growth bearing down on us before corrective action is taken. Or so goes the theory that accumulating externalities lead to catastrophe. This is another front along which the limits to growth are asserted, particularly by climate alarmists and the environmental Left. Most prominently today, they contend that increases in atmospheric carbon concentration will lead to an unlivable warming of Earth’s climate.

Sense and Nonsense

The most glaring shortcoming of climate change advocacy is that the trends it decries are exaggerated. I’ve discussed the absurdly brief climate record cited by alarmists in several past posts (many of which appear here). We can start with the contention that carbon emissions are “poison”. In fact, carbon is life nourishing, as we’ve witnessed with the “greening” of the planet at current carbon concentrations of 4 parts per 10,000 of atmospheric gas. Furthermore, a longer historical temperature record using paleoclimate data shows that we are well within the range of past variation, even with the huge distortions to the record caused by urban heat islands and questionable downward adjustments to records of five to 15 decades ago.

The alarmist perspective is also inflamed by simplistic models of carbon forcing that ignore the impact of solar radiation, volcanic activity, and the behavior of aerosols in the atmosphere. Those models have consistently over-predicted temperature trends for decades. Equally troubling is that these models promote the fiction that mankind can control global temperatures by a little fiddling with a “carbon dial”, as if such fiddling could be accomplished without a massive centralization of political and economic power. The panicked narratives related to sea level increases and alleged increases in violent weather are equally flawed.

Growth Can Cure It

Another compelling response to climate arguments against growth is that technological advances have already enabled us to produce power without carbon emissions. Unfortunately, as a matter of public policy (regulation and bad choices by government industrial planners), we have increasingly failed to avail ourselves of these opportunities, instead choosing extremely wasteful methods of generating power. These are the windmill and solar “renewables”, which are resource-intensive, intermittent, low utilization, non-dispatchable, lacking storage for excess generation, intensive in land use (reversing prior accretions), and environmentally disastrous in fabrication, operation, and at disposal. Nuclear power is a far superior technology, especially with the advent of small, modular reactors and potential breakthroughs in fusion energy. These might help to rescue us from the spectacle of bone-headed industrial planning and greedy, renewable-energy rent seekers, but regulators have done seemingly all they can to prevent nuclear facilities from being built.

Just as human ingenuity is capable of expanding the exploitable stock of tradable, priced resources, it is also capable of inventing non-carbon power technologies that are more efficient and less environmentally destructive than ground-based solar and wind. Collection of non-intermittent solar energy in space arrays with wireless transmission to Earth is another promising alternative, as is geothermal energy. And carbon capture technologies show promise for neutralizing emissions or perhaps even reversing carbon concentrations one day, if that is deemed necessary. Much of this development work is in private hands, but barring drastic reductions in scale, the bulk of these efforts are (or will be) dependent on government funding.

It’s worth acknowledging here that resource accretion has a safety component in an expected value sense. Sometimes those risks can be internalized if risk reduction is of value to buyers. But the costs of “reasonable” risk mitigation cannot always be internalized without government action. For example, deflecting asteroid threats to the planet might be done best by private actors, but paying for that activity is a worthy application of public finance. The ability to deflect incoming asteroids is a noteworthy example of resource accretion via risk reduction.

Somehow, governments must be convinced to begin dedicating a larger share of the vast sums they spend on misguided climate interventions (including renewable technologies) to more sensible innovations. We might then benefit from accelerated breakthroughs that would settle not only our energy future, but a great deal of political strife as well. Like the market response to changes in scarcity, creative entrepreneurs will always step forward to compete for government funding. But if you pay them for crap, you’ll get a lot of crap!

Growth Once More

One day we might learn we are reaching the top of an s-curve. We aren’t there yet, if our ongoing accretion of resources is any guide, and there are new frontiers of space and technology to explore. The primary obstacles we face are not natural, but political and regulatory.

One area neglected above is the accretion of human capital. Certainly education is another way to expand our boundaries. However, population growth (and therefore labor force growth) tends to slow as living standards rise, and many argue that demographics have already become a drag on growth. A shrinking and aging population places a tremendous burden on young workers, making other sources of growth and productivity all the more critical. But new physical capital, resource development (including education), and new technologies can all continue to drive productivity and growth.

Growth depends on resource accretion, and there are many ways in which our effective stock of resources can be expanded. That includes enhancements in quantities, efficiencies, and safety. Private investment should be the primary avenue through which these are accomplished, which in turn requires flows of saving. Those flows are much more difficult to conjure without growth, so we have a chicken and egg cross-dependency. But chickens will lay eggs, just as saving and all kinds of investment will take place given the right incentives. Those would promote expansion in our effective stock of resources, improved adaptation to change, and enhanced well being. In the end, the rationale is simple: ending poverty requires growth.

Addendum: I just noticed that Don Boudreaux posted (and beautifully elaborated upon) this great Julian Simon quote:

“The quantity of a natural resource that might be available to us – and even more important the quantity of the services that can eventually be rendered to us by that natural resource – can never be known even in principle, just as the number of points in a one-inch line can never be counted even in principle.”

The Futility and Falsehoods of Climate Heroics

The world’s gone far astray in attempts to battle climate change through forced reductions in carbon emissions. Last Wednesday, in an outrageously stupid ruling,a Dutch court ordered Royal Dutch Shell to reduce its emissions by 45% by 2030 relative to 2019 levels. It has nothing to do with Shell’s historical record on the environment. Rather, the Court said Shell’s existing climate action plans did not meet “the company’s own responsibility for achieving a CO2 reduction.” The decision will be appealed, but it appears that “industry agreements” under the Netherlands’ Climate Act of 2019 are in dispute.

Later that same day, a shareholder dissident group supporting corporate action on climate change won at least two ExxonMobil board seats. And then we have the story of John Kerry’s effort to stop major banks from lending to the fossil fuel industry. Together with the Biden Administration’s other actions on energy policy, we are witnessing the greatest attack on conventional power sources in history, and we’ll all pay dearly for it.

The Central Planner’s Conceit

Technological advance is a great thing, and we’ve seen it in the development of safe nuclear power generation, but the environmental left has successfully placed roadblocks in the way of its deployment. Instead, they favor the mandated adoption of what amount to beta versions of technologies that might never be economic and create extreme environmental hazards of their own (see here, here, here, and here). To private adopters, green energy installations are often subsidized by the government, disguising their underlying inefficiencies. These premature beta versions are then embedded in our base of productive capital and often remain even as they are made obsolete by subsequent advances. The “putty-clay” nature of technology decisions should caution us against premature adoptions of this kind. This is just one of the many curses of central planning.

Not only have our leftist planners forced the deployment of inferior technologies: they are actively seeking to bring more viable alternatives to ruination. I mentioned nuclear power and even natural gas offer a path for reducing carbon emissions, yet climate alarmists wage war against it as much as other fossil fuels. We have Kerry’s plot to deny funding for the fossil fuel industry and even activist “woke” investors, attempting to override management expertise and divert internal resources to green energy. It’s not as if renewable energy sources are not already part of these energy firms’ development portfolios. Allocations of capital and staff to these projects are usually dependent upon a company’s professional and technical expertise, market forces, and (less propitiously) incentives decreed by the government. Yet, the activist investors are there to impose their will.

Placing Faith and Fate In Models

All these attempts to remake our energy complex and the economy are based on the presumed external costs associated with carbon emissions. Those costs, and the potential savings achievable through the mitigation efforts of government and private greenies around the globe, have been wildly exaggerated.

The first thing to understand about the climate “science” relied upon by the environmental left is that it is almost exclusively model-dependent. In other words, it is based on mathematical relationships specified by the researchers. Their projections depend on those specs, the selection of parameter values, and the scenarios to which they are subjected. The models are usually calibrated to be roughly consistent with outcomes over some historical time period, but as modelers in almost any field can attest, that is not hard to do. It’s still possible to produce extreme results out-of-sample. The point is that these models are generally not estimated statistically from a lengthy sample of historical data. Even when sound statistical methodologies are employed, the samples are blinkingly short on climatological timescales. That means they are highly sample-specific and likely to propagate large errors out-of-sample. But most of these are what might be called “toy models” specified by the researcher. And what are often billed as “findings” are merely projections based on scenarios that are themselves manufactured by imaginative climate “researchers” cum grant-seeking partisans. In fact, it’s much worse than that because even historical climate data is subject to manipulation, but that’s a topic for another day.

Key Assumptions

What follows are basic components of the climate apocalypse narrative as supported by “the science” of man-made or anthropomorphic global warming (AGW):

(A) The first kind of model output to consider is the increase in atmospheric carbon concentration over time, measured in parts per million (PPM). This is a function of many natural processes, including volcanism and other kinds of outgassing from oceans and decomposing biomass, as well absorption by carbon sinks like vegetation and various geological materials. But the primary focus is human carbon generating activity, which depends on the carbon-intensity of production technology. As Ross McKitrick shows (see chart below), projections from these kinds of models have demonstrated significant upside bias over the years. Whether that is because of slower than expected economic growth, unexpected technological efficiencies, an increase in the service-orientation of economic activity worldwide, or feedback from carbon-induced greening or other processes, most of the models have over-predicted atmospheric carbon PPM. Those errors tend to increase with the passage of time, of course.

(B) Most of the models promoted by climate alarmists are carbon forcing models, meaning that carbon emissions are the primary driver of global temperatures and other phenomena like storm strength and increases in sea level. With increases in carbon concentration predicted by the models in (A) above, the next stage of models predicts that temperatures must rise. But the models tend to run “hot.” This chart shows the mean of several prominent global temperature series contrasted with 1990 projections from the Intergovernmental Panel on Climate Change (IPCC).

The following is even more revealing, as it shows the dispersion of various model runs relative to three different global temperature series:

And here’s another, which is a more “stylized” view, showing ranges of predictions. The gaps show errors of fairly large magnitude relative to the mean trend of actual temperatures of 0.11 degrees Celsius per decade.

(C) Climate sensitivity to “radiative forcing” is a key assumption underlying all of the forecasts of AGW. A simple explanation is that a stronger greenhouse effect, and increases in the atmosphere’s carbon concentration, cause more solar energy to be “trapped” within our “greenhouse,” and less is radiated back into space. Climate sensitivity is usually measured in degrees Celsius relative to a doubling of atmospheric carbon.

And how large is the climate’s sensitivity to a doubling of carbon PPM? The IPCC says it’s in a range of 1.5C to 4.5C. However, findings published by Nic Lewis and Judith Curry are close to the low end of that range, and are those found by the author of the paper described here.

In separate efforts, Finnish and Japanese researchers have asserted that the primary cause of recent warming is an increase in low cloud cover, which the Japanese team attributes to increases in the Earth’s bombardment by cosmic rays due to a weakening magnetic field. The Finnish authors note that most of the models used by the climate establishment ignore cloud formation, an omission they believe leads to a massive overstatement (10x) of sensitivity to carbon forcings. Furthermore, they assert that carbon forcings are mainly attributable to ocean discharge as opposed to human activity.

(D) Estimates of the Social Cost of Carbon (SCC) per ton of emissions are used as a rationale for carbon abatement efforts. The SCC was pioneered by economist William Nordhaus in the 1990s, and today there are a number of prominent models that produce distributions of possible SCC values, which tend to have high dispersion and extremely long upper tails. Of course, the highest estimates are driven by the same assumptions about extreme climate sensitivities discussed above. The Biden Administration is using an SCC of $51 per ton. Some recommend the adoption of even higher values for regulatory purposes in order to achieve net-zero emissions at an early date, revealing the manipulative purposes to which the SCC concept is put. This is a raw attempt to usurp economic power, not any sort of exercise in optimization, as this admission from a “climate expert” shows. In the midst of a barrage of false climate propaganda (hurricanes! wildfires!), he tells 60 Minutes that an acceptable limit on warming of 1.5C is just a number they “chose” as a “tipping point.”

As a measurement exercise, more realistic climate sensitivities yield much lower SCCs. McKitrick presents a chart from Lewis-Curry comparing their estimates of the SCC at lower climate sensitivities to an average of earlier estimates used by IPCC:

High levels of the SCC are used as a rationale for high-cost carbon abatement efforts. If the SCC is overstated, however, then costly abatements represent waste. And there is no guarantee that spending an amount on abatements equal to the SCC will eliminate the presumed cost of a ton’s worth of anthropomorphic warming. Again, there are strong reasons to believe that the warming experienced over the past several decades has had multiple causes, and human carbon emissions might have played a relatively minor role.

Crisis Is King

Some people just aren’t happy unless they have a crisis over which to harangue the rest of us. But try as they might, the vast resources dedicated to carbon reduction are largely wasted. I hesitate to say their effort is quixotic because they want more windmills and are completely lacking in gallantry. As McKitrick notes, it takes many years for abatement to have a meaningful impact on carbon concentrations, and since emissions mix globally, unilateral efforts are practically worthless. Worse yet, the resource costs of abatement and lost economic growth are unacceptable, especially when some of the most promising alternative sources of “clean” energy are dismissed by activists. So we forego economic growth, rush to adopt immature energy alternatives, and make very little progress toward the stated goals of the climate alarmists.

End of Snowfalls Is Greatly Exaggerated

Snowcover Anomoly

Everyone seems to think it snowed more in their youth than in recent years, but that’s generally incorrect, at least for for late-stage baby boomers, Gen Xers, and Millenials. Gregory Wrightstone thought the same thing as he reflected on his youth in Pittsburgh, but after checking snowfall records he was surprised to find an upward trend. In “Warming and the Snows of Yesteryear“, Wrightstone says his look at the records from other areas showed similar upward trends. The chart above from NOAA shows the Northern Hemisphere has experienced mostly positive snowfall anomalies over the past 20 years. So, the truth is that snowfalls have not decreased over the last 50+ years, contrary to our fond memories of big snows in childhood. Interestingly, Thomas Jefferson thought the same thing in 1801, but I’m not sure whether he was right.

We’ve been told by climate alarmists that “snowfalls are a thing of the past” due to global warming (The Independent in March, 2000). If anything, however, snowfalls have increased, and big snowfalls still happen. As with so many climate predictions over the years, this too is a bust. Most of those predictions have relied on predictive models fitted with an inadequate historical record of data, and the models are inadequately specified to capture the complexities of global climate trends. Don’t bet the house on them, and don’t presume to bet my house on them either, please!

Warming Bias and Hot-Town Thermometers

A few little-recognized facts about global warming are summarized nicely by climate researcher Javier in a comment on this post by Dr. Roy Spencer:

“It is mainly over land and not over sea. It is mainly in the Northern Hemisphere and not in the Southern Hemisphere. It is mainly during winter and not during summer. And it affects mainly minimal (night) temperature and not maximal (day) temperature.”

I added the hyperlinks to Javier’s comment. The last two items on his list emphasize a benign aspect of the warming we’ve experienced since the late 1970s. After all, cold temperatures are far deadlier than warm temperatures.

Here is a disclaimer: my use of the term “global warming” refers to the fact that averages of measured temperatures have risen in a few fits and starts over the past four decades. I do not use the term to mean a permanent trend induced by human activity, since that time span is very short in climatological terms, and the observed increase is well within the historical range of natural variation.

Few seem aware that the surface temperature record is plagued by an obvious issue: the siting of most weather stations in urban environments. In fact, urban weather stations account for 82% of total stations in the U.S., as Jim Steele writes of “Our Urban ‘Climate Crisis’“. Temperatures run hot in cities due to the heat-absorbing characteristics of building materials and the high proportion of impervious ground cover. And some stations well outside of metropolitan areas are also situated near concrete and pavement. There is little doubt that urbanization and thoughtless siting decisions for weather stations have corrupted temperature measurements and exaggerated surface warming trends.

Hot summer days always arouse expressions of climate alarm. However, increases in summer temperatures, and daytime temperatures, have been relatively modest compared to increases in winter and nighttime temperatures. In Roy Spencer’s post, (also linked above), he reports that 80% of the U.S. warming observed by a NASA satellite system (AIRS) from September 2002 to March 2019 occurred at night.

Of course, climate alarmists also claim that global warming makes temperatures more volatile. So, they argue, there are now more very hot days even if the change in the average summer temperature is modest. The facts do not support that claim, however. Indeed, the world has experienced less temperature volatility as global temperatures have risen. And less extreme weather, as it happens, is contrary to another theme in the warmest narrative.

There is some reason to believe that the relative increase in nighttime temperature is connected to the urban heat island effect. Pavement, concrete, and other materials retain heat overnight. Thus, increasing urbanization leads to nighttime temperatures that do not fall from their daily highs as much as they did a few decades back. The magnification of daytime heating is not as pronounced as the effect of retained heat overnight, which causes the diurnal temperature range to decrease. But I should note that some rural farmers insist that nighttime lows have increased relative to daytime highs there as well, and Roy Spencer himself is not confident that the satellite temperature data on which his finding was based reflects a strong urban heat island effect.

For perspective, it’s good to remember that we live in the midst of an interglacial period. These are relatively brief, temperate intervals between lengthier glacial periods (see here, and more from Javier here). The current interglacial is well advanced, having begun about 11,700 years ago, but Javier estimates that it could last for another 1,500 years. That would be longer than the historical average. At the peak of the last interglacial period, temperatures were about 2C higher than today and sea levels were 5 meters higher. The last interglacial ended about 120,000 years ago, but the historical average time between interglacials is only about 41,000 years. These low frequency changes in the global climate are generally driven by the Earth’s axial tilt (obliquity), recurring cycles in the shape of our eliptical orbit around the Sun (eccentricity), and the Earth’s solar exposure (insolation) and albedo.

Biased surface temperature records have both inspired and reinforced the sense of panic surrounding global warming. Few observers seem to understand the existence of a strong bias, let alone its source: the urban heat island effect. And few seem to realize that most of the warming we’ve experienced since the 1970s has occurred at night, not during the day, and that these changes are well within the range of natural variation. Dramatic climate change happens at both long and short time scales for reasons that are largely astronomical. The lengthy historical record accumulated by paleoclimatologists shows that current concerns over global warming are exaggerated. I’m quite confident that mankind will find ways to adapt to climate change in either direction, but some global warming might be beneficial once the next glacial period begins.

The Non-Trend In Hurricane Activity

People are unaccountably convinced that there is an upward trend in severe weather events due to global warming. But there is no upward trend in the data on either the frequency or severity of those events. Forget, for the moment, the ongoing debate about the true extent of climate warming. In fact, I’ll stipulate that warming has occurred over the past 40 years, though most of it was confined to the jump roughly coincident with two El Ninos in the 1990s; there’s been little if any discernible trend since. But what about the trend in severe weather? I’ve heard people insist that it is true, but a few strong hurricanes do not constitute a trend.

The two charts at the top of this post were created by hurricane expert Ryan N. Maue. I took them from an article by David Middleton., but visit Maue’s web site on tropical cyclone activity for more. The last month plotted is September 2018, so the charts do not account for Hurricane Michael and the 2018 totals are for a partial year. The first nine months of each year typically accounts for about 3/4 of annual tropical cyclones, so 2018 will be a fairly strong year. Nevertheless, the charts refute the contention that there has been an upward trend in tropical cyclone activity. In fact, in the lower chart, the years following the 1990s increase in global temperatures is shown to have been a time a lower cyclone energy. Roy Spencer weighs in on the negative trend in major landfalling hurricanes in the U.S. and Florida stretching over many decades.

Warren Meyer blames ‘”media selection bias” for the mistaken impression of dangerous trends that do not exist. That is, the news media are very likely to report extreme events, as they should, but they are very unlikely to report a paucity of extreme events, no matter how lengthy or unusual the dearth:

“Does anyone doubt that if we were having a record-heavy tornado season, this would be leading every newscast? [But] if a record-heavy year is newsworthy, shouldn’t a record-light year be newsworthy as well? Apparently not.”

It so happens that 2018, thus far, has seen very close to a record low number of tornadoes in the U.S.

Meyer also highlights the frequent use of misleading statistics on the real value of damage from natural disasters. That aggregate value has almost certainly grown over the years, but it had nothing to do with the number or severity of natural disasters. Meyer explains:

“Think about places where there are large natural disasters in the US — two places that come to mind are California fires and coastal hurricanes. Do you really think that the total property value in California or on the US coastline has grown only at inflation? You not only have real estate price increases, but you have the value of new construction. The combination of these two is WAY over the 2-3% inflation rate.”

Recent experiences are always the most vivid in our minds. The same is true of broad impressions drawn from reports on the most recent natural disasters. The drama and tragedy of these events should never be minimized, and the fact that there is no upward trend in cyclone activity is no consolation to victims of those disasters. Still, the media can’t seem to resist the narrative that the threat of such events is increasing, even if it can’t be proven. Indeed, even if it’s not remotely correct. Reporters are human and generally not good at science, and they are not immune to the tendency to exaggerate the significance of events upon which they report. A dangerous, prospective trend is at once scary, exciting, and possibly career-enhancing. As for the public, sheer repetition is enough to convince most people that such a threat is undeniable… that everybody knows it… that the trend is already underway. The fact is that the upward trend in hurricane activity (and other kinds of severe weather) is speculative, not real.

Deceits of the Climate Claimants

Well-meaning souls innocently parrot the global warming narrative but generally know little of the controversies surrounding its validation, or lack thereof. That includes much of the mainstream media. Every warm day is evidence of global warming. Every cold day is evidence of extreme volatility brought on by climate change. Every big storm, every forest fire, and every endangered species is attributed to warming. The poles are melting, the sea is rising, the sky is falling, and it is mostly bullshit. But in the meantime, the mythology of global warming has become an all-purpose cudgel for state oversight and “redistributive justice”, primarily to the benefit of the “climate change industrial complex. The myths are repeated so frequently that many accept them as facts. Here, I list a few of these myths along with information that should give pause to anyone tempted to take them too seriously.

The science is settled: There are a number of great scientists who dispute the global warming narrative (and see here). But a few studies have claimed incredibly widespread consensus (97%) among scientists that mankind drives climate change. These studies are generally plagued by biased samples of scientists (sometimes including non-scientists), faulty selection and classification of paper abstracts, and direct involvement of climate activists in the research process. These studies tend to present the “consensus” as one side of a stark dichotomy, with no nuance or middle ground for those subscribing to anything less than the inevitability of a warming catastrophe.

Record high temperatures: The temperatures that are almost always reported are surface temperatures that are subject to extreme bias. The most drastic bias is caused by increasing urbanization. Urban weather instruments are often sited in areas with an increasing amount of impervious ground cover, which absorbs sunlight and heat, leading to the so-called “urban heat-island effect”. This has imparted an upward trend in urban temperature readings. Moreover, urban temperature readings tend to be over-sampled in estimates of global surface temperatures, reinforcing the distortions in measured warming.

Melting poles: Arctic sea ice extent has been in modest retreat since 1980, when satellite measurement began to allow more accurate readings. The Antarctic, however, has shown a trend in the other direction, as shown in this piece by Judith Curry. In the same article, Curry shows that specific Arctic locations had less sea ice 6,000 to 8,000 years ago than today. For more complete information on satellite-era trends in sea ice extent, see this informative reference page (scroll way down for Antarctic information). Looks like Al Gore’s dire prediction that the poles would melt by 2007 was just a little off target.

Polar bear extinction: We are constantly seeing warnings of polar bear extinction on social media. Memes feature desperate-looking bears stranded on ice floes, drifting away from their cubs. Perhaps you aren’t supposed to know that polar bears are extremely strong swimmers. Or that the polar bear population is been thriving, increasing by an estimated 10-20% since 2001. So whether or not the past few decades have seen a decline in sea ice, the bears seem be doing just fine.

Rising sea levels: The rate of increase in sea levels over the past 8,000 years has been vey slow relative to the 10,000 years prior to that, when they rose at rates of up to 5.5 meters per century. That compares to recent rates of about one foot per century. Predictions that islands in the Pacific would be swallowed by the seas have not come to pass. In fact, satellite images show that more of the world’s sandy shorelines accreted than receded between 1984 and 2016, This does not appear to be a crisis by any means.

Increasing storms: No, the frequency and intensity of tropical cyclone activity has decreased since 1900, a trend that has continued unabated over the past 20 years. I know of at least one study suggesting otherwise, but it is based purely on modeled relationships, not hard data, and not tested against data. The frequency and intensity of droughts and floods has been flat to declining as well. And while more weak tornadoes are detected today than in the past, the frequency of moderate to strong tornadoes has decreased over the past 45 years.

Desertification: Increases in carbon concentration have not been associated with desertification, as the media seem to have concluded. As noted above, the frequency of drought has been steady to declining. In fact, precipitation data suggests that patterns of variability in rainfall do not square with the predictions of climate models. In fact, the world has seen an increase in green vegetation since 1985, even in arid regions.

Ocean acidification: The reported declines in ocean pH levels over the past few centuries are actually smaller than the normal seasonal variation in pH levels. The presumed negative impact on sea life appears, after all, to be minimal to nonexistent (see the same link).

Higher alpine tree lines: We’ve been waiting. It hasn’t happened, but that hasn’t stopped some activists from stating it as established fact.

Armadillo northward migration: I’ve heard this cited as “proof” of global warming. The range of armadillos extended as far north as southern Missouri and Kansas in the early 1970s, so this isn’t new. In fact, armadillos began their migration northward into the U.S. before the mid-1800s. Some biologists have attributed the migration to warming but acknowledge many other reasons, including more forested habitat in the north and factors such as movement of cattle by rail. Armadillos burrow and are able to keep warm underground in the winter. Of course, a series of warm winters can bring them further north along with other species, but a few cold winters can take a toll on the population and push them south again.

U.S. carbon criminality: U.S. CO2 emissions have been in almost steady decline on a per capita basis for at least seven decades, long before the carbon freak-out began. The declines have resulted largely from the normal market process of competitive efficiency in production. China leads the world in total annual CO2 emissions by a wide margin, about 80% ahead of the U.S. in 2017. Total U.S. emissions actually declined in 2017 for the third straight year, while emissions in China, the EU, and for the world all increased. In fact, China was actually in compliance with its pledge under the Paris Accord despite the increase, so the pledge was not especially ambitious.

High social cost of carbon: The estimates used by the Environmental Protection Agency are plagued by poor methodology and are subject to great uncertainty. Some studies rely on a series of tenuous causal links, such as CO2 emissions to global temperatures to ice melt to sea level to real dollars of coastal damage many years hence, all without considering variances at each stage, and assuming zero effort to adapt or mitigate damages over long time frames. A shortcut approach relies on historical correlations between temperatures and such measures as heat-related deaths, labor productivity and real output. These estimates extrapolate old relationships to the distant future and ignore the very real human tendency to adapt. The underlying assumptions are undercut by such basic facts as ongoing migration to warmer regions. The estimates also fail to account for the likelihood that warmer weather will improve agricultural productivity.

The public’s interest in climate change has waned, and no wonder: sensible people do not buy hype and demands for sacrifice in the face of contradictory evidence. Revelations of statistical fraud have led to even more skepticism. And when your “proof” is founded on model extrapolation, often theoretically-based rather than empirically-based, you’re skating on thin scientific ice. At this link, Steven Hayward has an interesting take on the public’s increasingly jaundiced view of global warming activism:

“Scientists who are genuinely worried about the potential for catastrophic climate change ought to be the most outraged at how the left politicized the issue and how the international policy community narrowed the range of acceptable responses. Treating climate change as a planet-scale problem that could be solved only by an international regulatory scheme transformed the issue into a political creed for committed believers. Causes that live by politics, die by politics.”

The nasty spate of hurricanes this year has been a catch-up of sorts following a decade of subdued activity. In fact, global hurricane activity has been flat to declining in frequency since 1970. Until the recent increase, hurricane activity had been trending down in terms of 24-month cumulative energy since the 1990s, as the chart above shows. The historical data on the number of U.S. landfalls extends back to 1900, and it has had a negative trend as well. Nevertheless, we hear from climate alarmists that Hurricanes Harvey and Irma, which ended a drought of record length in U.S hurricane landfalls, and now presumably Maria, were a consequence of anthropomorphic global warming (AGW), er… climate change.

The implication is that increases in the atmospheric concentration of CO2 led to these hurricanes or their high intensity. Apparently, the paucity of hurricane activity over the previous ten years can be waved off as a fluke. A further implication of the alarmist view is that the longer negative trends in hurricane frequency and energy can be ignored in the context of any relation to CO2 concentration. But how so? One confounding factor I’ve seen mentioned blames El Nino warming in the Pacific, and a consequent increase in Atlantic wind shear, for the long lull in activity after 2005. That has a ring of plausibility, but a closer look reveals that actual El Nino activity during those years was hardly impressive, with the exception of 2015-16.

More historical data can be seen in the charts on the tropical cyclone page on the Watts Up With That? blog. (The charts in question start about two-thirds of the way down the page.) Hurricane expert Ryan Maue compiled a number of these charts, including the one above. He authored an editorial in the Wall Street Journal this week bemoaning the climate-change hype surrounding Harvey and Irma (if the link doesn’t work, it is available at the WSJ’s Opinion page on Facebook, posted on 9/17). Maue believes that both the climate science community and the media share in the blame for that hype. But he also says the following:

“Although a clear scientific consensus has emerged over the past decade that climate change influences hurricanes in the long run, its effect upon any individual storm is unclear.“

Maue provides a link to this NOAA web site offering cautious support for the proposition that there is a link between global warming and hurricane intensity, though the data it cites ends about ten years ago, so it does not capture the recent lull. Also, some of the information it provides is based on modeled global temperatures and hurricane activity through 2100. As is well-known by now, or should be, long-term climate forecasts based on carbon forcings are notoriously inaccurate, and NOAA admits that the association between those predicted temperatures and future hurricanes is tenuous:

“It is premature to conclude that human activities–and particularly greenhouse gas emissions that cause global warming–have already had a detectable impact on Atlantic hurricane or global tropical cyclone activity.“

Perhaps the idea that there is consensus regarding the relationship between climate change and hurricanes is more of a stretch than Maue and NOAA let on. Here is a summary of 30 peer-reviewed studies showing no connection to either hurricane frequency or intensity. Most of these studies are more recent than the end of the data record cited by NOAA. And in fact, many of these studies find support for a negative link between global temperatures and hurricane activity.

One of the prominent alarmists in the climate research community is Penn State’s Michael Mann, who has famously claimed that hurricanes are more frequent now than at any time in the past 1,000 years. He based his conclusions on highly speculative hurricane “proxies” identified in layers of sediment. Mann’s claims and research technique have been called into questioned by other climate scientists, who have arrived at contrary results in their own research. Lest anyone forget, Mann was implicated in a data manipulation fraud related to the East Anglia climate scandal. Though cleared by a group of tenured professors at his own university, there are a number of climate scientists who believe Mann violated scientific standards.

The claim that global warming will cause hurricanes to become increasingly intense relies on elevated sea surface temperatures. This year, temperatures in the Gulf of Mexico are elevated and are said to have had a role in strengthening Harvey as it approached the Gulf Coast. Texas, however, has experienced as many landfalls of major hurricanes with cooler Gulf waters as with warmer waters. And Irma strengthened in a part of the Atlantic without such warm temperatures. Instead, minimal wind shear was implicated as a factor contributing to Irma’s strength.

In general, Atlantic temperatures have been relatively warm since the late 1990s, a fact that most scientists would at least partially attribute to the “Atlantic multi-decadal oscillation“, a regular cycle in water temperatures that repeats with a period of multiple decades. Potentially adding to that temperature increase is a controversial change in NOAA’s calibration of sea surface temperatures, as an increasing share of those readings are taken from buoys rather than ship-board measurement. There is some suspicion that NOAA’s adjustments “cool the past” more than is justified, a suspicion that was heightened by allegations from one whistle-blowing NOAA scientist early this year. Then, there is the contention that the sea surface temperature makes little difference if it is matched by an increase in air temperature.

Overall, NOAA says the combination of frequency and intensity of tropical cyclones will increase by 2%-11% over the rest of this century. As Roy Spencer notes, that is not a terribly alarming figure given the risks people have always willingly accepted by living in coastal areas. In any case, the range is based on models of climate behavior that are of questionable reliability. And like past temperature predictions produced by carbon-forcing climate models, it is likely to be a gross overestimate. Here is Roger Pielke, Sr., who is quoted in this wide-ranging post on hurricanes and climate at the Fabius Maximus web site:

“Model projections of hurricane frequency and intensity are based on climate models. However, none have shown skill at predicting past (as hindcasts) variations in hurricane activity (or long term change in their behavior) over years, decades, and longer periods. Thus, their claim of how they will change in the future remains, at most, a hypothesis (i.e. speculation). When NOAA, IPCC and others communicate to the media and public, to be scientifically honest, they should mention this.”

Despite the spike in activity this year, strong hurricanes are intermittent and fairly rare. Establishing reliable statistical connections with other forces is difficult with emergent events like hurricanes. Moreover, the degree of error in measuring global or regional temperature itself is much larger than is generally acknowledged, and the global warming “signal” is very weak. As we say in the statistical analysis business, noisy data are compatible with diverse hypotheses. The relationship between hurricanes and climate change is a prime example.

Satellite records show that our world is experiencing a remarkable “greening” in the 21st century, to the seeming chagrin of the environmental left. There is now more vegetation than two decades ago, and greener vegetation, across as much as 50% of the Earth’s vegetated surface area. That area is expanding as well, and the creeping greenery has improved soil moisture levels in some drylands. This bodes well for agricultural productivity, putting another nail in Malthus’ coffin. The satellite studies have concluded that most of the enhanced vegetation is attributable to greater concentration of CO2 in the atmosphere, as opposed to warming or other possible causes. An interesting feedback is that the enhanced vegetation increases natural absorption of CO2, providing an enhanced carbon sink. This, in turn, has caused a pause in the growth of atmospheric carbon cencentration.

The environmental left knows these developments tend to undermine their preferred narrative that human emissions of CO2 must be reduced — at any cost. In fact, already there are warnings that global greening will “outgrow its benefit” as the greater volume of plants begins to decay, releasing carbon. You just can’t make some people happy! But not all of the carbon release from plant decay adds to atmospheric carbon — some is soil-bound — so the greening should provide a fairly durable carbon sink.

Global greening was one of the major motifs in Matt Ridley’s 2016 Global Warming Policy Foundation Lecture. Ridley covered various evidence of greening, but he also discussed the failure of a large contingent of climate researchers to follow a legitimate scientific approach to the study of climate change. Instead, they have politicized their field of study, committing a few noteworthy frauds along the way:

“It is irresponsible not to challenge the evidence properly, especially if the policies pursued in its name are causing suffering. Increasingly, many people would like to outlaw, suppress, prosecute and censor all discussion of what they call ‘the science’ rather than engage in debate. …

No wonder that I talk frequently to scientists who are skeptical, but dare not say so openly. That is a ridiculous state of affairs. We’re told that it’s impertinent to question “the science” and that we must think as we are told. But arguments from authority are the refuge of priests. Thomas Henry Huxley put it this way: ‘The improver of natural knowledge absolutely refuses to acknowledge authority, as such. For him, scepticism is the highest of duties; blind faith the one unpardonable sin’.

What keeps science honest, what stops it from succumbing entirely to confirmation bias, is that it is decentralized, allowing one lab to challenge another.“

It is all too true that policies advanced in the interests of curbing a slight warming trend cause real suffering, and the pain is heavily concentrated on the most impoverished. The presumed benefits of activist climate-change policies are speculative, at best. They have little chance of reversing atmospheric carbon concentration on their own.

Ridley makes note of the substantial evidence that sensitivity of the climate to airborne carbon concentration is low. This has become increasingly evident with the unfolding of a consistent record of over-forecasts of global temperatures by climate forcing models. Roy Spencer provides insights about these models in a recent discussion of global warming and “dodgy science” on his blog.

There is a widespread myth that 97 percent of climate scientists believe human activity is the main cause of global warming. In fact, that claim was based on a paper counting citations, not scientists; the methods used in the study and the citations themselves were also questionable. I have reviewed that evidence here on Sacred Cow Chips. David Henderson reviewed it here. A large number of studies find fault with so-called “consensus” pronouncements. They should always be viewed with suspicion.

There is also a lively debate underway over whether CO2 should be considered a pollutant! I exhale, therefore I pollute? To the extent that fecal matter is considered a pollutant, is it fair that to say that CO2 is, too? After all, both are anthropogenic. No, they are not even close in terms of an immediate threat to human health. As a philosophical matter, the idea that anything done by man is “unnatural” denies the fact that we are a very part of nature. Obviously, CO2 is not in the same class as pollutants like sulfur dioxide, ammonia, carbon monoxide or toxic metals. Today, these pollutants are very common in many parts of the world, and they are very threatening to human life. Effective mitigation technologies are available, but instead, in the developed West, we fixate on an increase in CO2 concentration of 100 parts per million over many decades, the climate implications of which are de minimis.

Rand Paul’s Facebook page has an ungated link to a WSJ.com commentary by Rodney W. Nichols and Harrison H. Schmitt on “The Phony War Against CO2”. Their commentary provokes questions as to the motives of the environmental left, and certain members of the research community, in shilling for the cause. That we would fight the greening of the globe, and the potential agricultural benefit it could bring, is bizarre. To devote enormous resources to an endeavor that is largely futile is a waste and a tragedy.
