There was deep disappointment among political opponents of Florida Governor Ron DeSantis at their inability to pin blame on him for Hurricane Ian’s destruction. It was a terrible hurricane, but they so wanted it to be “Hurricane Hitler”, as Glenn Reynolds noted with tongue in cheek. That just didn’t work out for them, given DeSantis’ competent performance in marshaling resources for aid and cleanup from the storm. Their last ditch refuge was to condemn DeSantis for dismissing the connection they presume to exist between climate change and hurricane frequency and intensity. That criticism didn’t seem to stick, however, and it shouldn’t.

There is no linkage to climate change in actual data on tropical cyclones. It is a myth. Yes, models of hurricane activity have been constructed that embed assumptions leading to predictions of more hurricanes, and more intense hurricanes, as temperatures rise. But these are models constructed as simplified representations of hurricane development. The following quote from the climate modelers at the Geophysical Fluid Dynamics Laboratory (GFDL) (a division of the National Oceanic and Atmospheric Administration (NOAA)) is straightforward on this point (emphases are mine):

“Through research, GFDL scientists have concluded that it is premature to attribute past changes in hurricane activity to greenhouse warming, although simulated hurricanes tend to be more intense in a warmer climate. Other climate changes related to greenhouse warming, such as increases in vertical wind shear over the Caribbean, lead to fewer yet more intense hurricanes in the GFDL model projections for the late 21st century.

Models typically are said to be “calibrated” to historical data, but no one should take much comfort in that. As a long-time econometric modeler myself, I can say without reservation that such assurances are flimsy, especially with respect to “toy models” containing parameters that aren’t directly observable in the available data. In such a context, a modeler can take advantage of tremendous latitude in choosing parameters to include, sensitivities to assume for unknowns or unmeasured relationships, and historical samples for use in “calibration”. Sad to say, modelers can make these models do just about anything they want. The cautious approach to claims about model implications is a credit to GFDL.

Before I get to the evidence on hurricanes, it’s worth remembering that the entire edifice of climate alarmism relies not just on the temperature record, but on models based on other assumptions about the sensitivity of temperatures to CO2 concentration. The models relied upon to generate catastrophic warming assume very high sensitivity, and those models have a very poor track record of prediction. Estimates of sensitivity are highly uncertain, and this article cites research indicating that the IPCC’s assumptions about sensitivity are about 50% too high. And this article reviews recent findings that carbon sensitivity is even lower, about one-third of what many climate models assume. In addition, this research finds that sensitivities are nearly impossible to estimate from historical data with any precision because the record is plagued by different sources and types of atmospheric forcings, accompanying aerosol effects on climate, and differing half-lives of various greenhouse gases. If sensitivities are as low as discussed at the links above, it means that predictions of warming have been grossly exaggerated.

The evidence that hurricanes have become more frequent or severe, or that they now intensify more rapidly, is basically nonexistent. Ryan Maue and Roger Pielke Jr. of the University of Colorado have both researched hurricanes extensively for many years. They described their compilation of data on land-falling hurricanes in this Forbes piece in 2020. They point out that hurricane activity in older data is much more likely to be missing and undercounted, especially storms that never make landfall. That’s one of the reasons for the focus on landfalling hurricanes to begin with. With the advent of satellite data, storms are highly unlikely to be missed, but even landfalls have sometimes gone unreported historically. The farther back one goes, the less is known about the extent of hurricane activity, but Pielke and Maue feel that post-1970 data is fairly comprehensive.

The chart at the top of this post is a summery of the data that Pielke and Maue have compiled. There are no obvious trends in terms of the number of storms or their strength. The 1970s were quiet while the 90s were more turbulent. The absence of trends also characterizes NOAA’s data on U.S. landfalling hurricanes since 1851, as noted by Pail Driessen. Here is Driessen on Florida hurricane history:

“Using pressure, Ian was not the fourth-strongest hurricane in Florida history but the tenth. The strongest hurricane in U.S. history moved through the Florida Keys in 1935. Among other Florida hurricanes stronger than Ian was another Florida Keys storm in 1919. This was followed by the hurricanes in 1926 in Miami, the Palm Beach/Lake Okeechobee storm in 1928, the Keys in 1948, and Donna in 1960. We do not know how strong the hurricane in 1873 was, but it destroyed Punta Rassa with a 14-foot storm surge. Punta Rassa is located at the mouth of the river leading up to Ft. Myers, where Ian made landfall.”

Neil L. Frank, veteran meteorologist and former head of the National Hurricane Center, bemoans the changed conventions for assigning names to storms in the satellite era. A typical clash of warm and cold air will often produce thunderstorms and wind, but few of these types of systems were assigned names under older conventions. They are not typical of systems that usually produce tropical cyclones, although they can. Many of those kinds of storms are named today. Right or wrong, that gives the false impression of a trend in the number of named storms. Not only is it easier to identify storms today, given the advent of satellite data, but storms are assigned names more readily, even if they don’t strictly meet the definition of a tropical cyclone. It’s a wonder that certain policy advocates get away with saying the outcome of all this is a legitimate trend!

As Frank insists, there is no evidence of a trend toward more frequent and powerful hurricanes during the last several decades, and there is no evidence of rapid intensification. More importantly, there is no evidence that climate change is leading to more hurricane activity. It’s also worth noting that today we suffer far fewer casualties from hurricanes owing to much earlier warnings, better precautions, and better construction.

The SEC’s Absurd Climate Overreach

The Securities and Exchange Commission recently issued a proposed rule for reporting on climate change risk, and it is fairly outrageous. It asks that corporations report on their own direct greenhouse gas emissions (GHG – Scope 1), the emissions caused by their purchases of energy inputs (Scope 2), and the emissions caused by their “downstream” customers and “upstream” suppliers (Scope 3). This is another front in the Biden Administration’s efforts to bankrupt producers of fossil fuels and to force the private sector to radically alter its mix of energy inputs. The SEC’s proposed “disclosures” are sheer lunacy on several levels.

The SEC Mandate

If implemented, the rule would allow the SEC to stray well outside the bounds of its regulatory authority. The SEC’s role is not to regulate emissions or the environment. Rather, as its web site makes clear, the agency is charged with:

“… protecting investors, maintaining fair, orderly, and efficient markets, and facilitating capital formation.”

Given this mission, the SEC requires management to disclose material financial risks. Are a firm’s GHG emissions really material risks? The first problem here is quite practical: John Cochrane notes the outrageous costs that would be associated with compliance:

“‘Disclosure’ usually means revealing something you know. A perfectly honest answer to ‘disclose what you know about your carbon emissions’ is, ‘we have no idea what our carbon emissions are.’ Back that up with every document the company has ever produced, and you have perfectly ‘disclosed.’ There is no asymmetric information, fraud, etc.

The SEC has already required the production of new information, and as Hester Peirce makes perfectly clear, the climate rules again make a huge dinner out of that appetizer: essentially telling companies to hire a huge number of climate consultants to generate new information, and also how to run businesses.”

In a separate post, Cochrane quotes SEC Commissioner Hester Peirce’s response to the proposed rule. She emphasizes that companies are already required to disclose all material risks. Perhaps they have properly declined to disclose climate risks because those risks are not material.

“Current SEC disclosure mandates are intended to provide investors with an accurate picture of the company’s present and prospective performance through managers’ own eyes. How are they thinking about the company? What opportunities and risks do the board and managers see? What are the material determinants of the company’s financial value?”

Identifying the Risk Causers

Regardless of the actual risks to a firm caused by climate change, the SEC’s proposed GHG disclosures put a more subtle issue into play. Peirce describes what amounts to a fundamental shift in the SEC’s philosophy regarding the motivation and purpose of disclosure:

The proposal, by contrast, tells corporate managers how regulators, doing the bidding of an array of non-investor stakeholders, expect them to run their companies. It identifies a set of risks and opportunities—some perhaps real, others clearly theoretical—that managers should be considering and even suggests specific ways to mitigate those risks. It forces investors to view companies through the eyes of a vocal set of stakeholders, for whom a company’s climate reputation is of equal or greater importance than a company’s financial performance.”

In other words, a major risk faced by these firms has nothing to do with climate change itself, but with perceptions of “climate-related” risks by other parties. That transforms the question of climate risk into something that is, in fact, regulatory and political. Is this the true nature of the SEC’s concern, all dressed up in the scientism typically relied upon by climate change activists?

The reaction of government bureaucrats to the risks they perceive is a palpable threat to investor well-being. For example, GHG emissions might lead to future regulatory sanctions from various government agencies, including fines, taxes, various sanctions, and mitigation mandates. In addition, with the growth of investment management based on what are essentially shambolic and ad hoc ESG scores, GHG or carbon emissions might lead to constraints on a firm’s access to capital. Just ask the oil and gas industry! That penalty is imposed by activist investors and fund managers who wish to force an unwise and premature end to the use of fossil fuels. There is also a threat that GHG disclosures themselves, based (as they will be) on flimsy estimates, could create litigation risk for many companies.

Much Ado About Nothing

While there are major regulatory and political risks to investors, let’s ask, for the sake of argument: how would one degree celcius of warming by the end of this century affect corporate results? Generally not at all. (The bounds described in the Paris Agreement are 1.5 to 2 degrees, but these are based on unrealistic scenarios — see links below.) It would happen gradually in any case, with ample opportunity to adapt to the operating environment. To think otherwise requires great leaps of imagination. For example, climate alarmists probably fancy that violent weather or wildfires will wipe out facilities, yet there is no reliable evidence that the mild warming experienced to-date has been associated with more violent weather or an increased incidence of wildfires (and see here). There are a great many “sacred cows” worshiped by climate-change neurotics, and the SEC undoubtedly harbors many of those shibboleths.

What probabilities can be attached to each incremental degree of warming that might occur over several decades. The evidence we’ve seen comes from so-called carbon-forcing models parameterized for unrealistically high carbon sensitivities and subjected to unrealistic carbon-concentration scenarios. Estimates of these probabilities are not reliable.

Furthermore, climate change risks, even if they could be measured reliably in the aggregate, cannot reasonably be allocated to individual firms. The magnitude of the firm’s own contribution to that risk is equivalent to the marginal reduction in risk if the firm implemented a realistic zero-carbon operating rule. For virtually any firm, we’re talking about something infinitesimal. It involves tremendous guesswork given that various parties around the globe take a flexible approach to emissions, and will continue to do so. The very suggestion of such an exercise is an act of hubris.

Back To The SEC’s Mandated Role

Let’s return to the practical problems associated with these kinds of disclosure requirements. Cochrane also points out that the onerous nature of the SEC proposal, and the regulatory and political threats it embodies, will hasten the transition away from public ownership in many industries.

“The fixed costs alone are huge. The trend to going private and abandoning public markets, at least in the U.S. will continue. The trend to large oligopolized politically compliant static businesses in the U.S. will continue.

I would bet these rules wind up in court, and that these are important issues. They should be.”

Unfortunately, private companies will still have to to deal with certain investors who would shackle their use of energy inputs and demand forms of diligence (… not to say “due”) of their own.

The SEC’s proposed climate risk disclosures are stunningly authoritarian, and they are designed to coalesce with other demands by the regulatory state to kill carbon-based energy and promote renewables. These alternative energy sources are, as yet, unable to offer an economical and stable supply of power. The fraudulent nature of the alleged risks make this all the more appalling. The SEC has effectively undertaken an effort to engage in corporatist industrial policy benefitting a certain class of “green” energy investors, exposing the proposal as yet another step on the road to fascism. Let’s hope Cochrane is right: already, 16 state attorneys general are preparing a legal challenge. May the courts ultimately see through the SEC’s sham!

Climate Alarmism and Junk Science

Carbon Forcing Models, Climate Alarmism, Green Subsidies, Intergovernmental Panel on Climate Change, IPCC, Kevin Trenberth, Model Bias, Model Ensembles, National Center for Atmospheric Research, Norman Rogers, Redistribution, rent seeking

The weak methodology and accuracy of climate models is the subject of an entertaining Norman Rogers post. I want to share just a few passages along with a couple of qualifiers.

Rogers quotes Kevin Trenberth, former Head of Climate Analysis at the National Center for Atmospheric Research, with apparent approval. Oddly, Rogers does not explain that Trenberth is a strong proponent of the carbon-forcing models used by the UN’s Intergovernmental Panel on Climate Change (IPCC). He should have made that clear, but Trenberth actually did say the following:

“‘[None of the] models correspond even remotely to the current observed climate [of the Earth].’“

I’ll explain the context of this comment below, but it constitutes a telling admission of the poor foundations on which climate alarmism rests. The various models used by the IPCCc are all a little different and they are calibrated differently. I’ve noted elsewhere that their projections are consistently biased toward severe over-predictions of temperature trends. Rogers goes on from there:

“The models can’t properly model the Earth’s climate, but we are supposed to believe that, if carbon dioxide has a certain effect on the imaginary Earths of the many models it will have the same effect on the real earth.”

But how on earth can a modeler accept the poor track record of these models? It’s not as if the bias is difficult to detect! On this question, Rogers says:

“The climate models are an exemplary representation of confirmation bias, the psychological tendency to suspend one’s critical facilities in favor of welcoming what one expects or desires. Climate scientists can manipulate numerous adjustable parameters in the models that can be changed to tune a model to give a ‘good’ result.“

And why are calamitous projections desirable from the perspective of climate modelers? Follow the money and the status rewards of reinforcing the groupthink:

“Once money and status started flowing into climate science because of the disaster its denizens were predicting, there was no going back. Imagine that a climate scientist discovers gigantic flaws in the models and the associated science. Do not imagine that his discovery would be treated respectfully and evaluated on its merits. That would open the door to reversing everything that has been so wonderful for climate scientists. Who would continue to throw billions of dollars a year at climate scientists if there were no disasters to be prevented? “

Indeed, it has been a gravy train. Today, it is reinforced by green-preening politicians, the many billions of dollars committed by investors seeking a continuing flow of public subsidies for renewables, tempting opportunities for international redistribution (and graft), and a mainstream media addicted to peddling scare stories. The parties involved all rely on, and profit by, alarmist research findings.

Rogers’ use of the Trenberth quote above might suggest that Trenberth is a critic of the climate models used by the IPCC. However, the statement was in-line with Trenberth’s long-standing insistence that the IPCC models are exclusively for constructing “what-if” scenarios, not actual forecasting. Perhaps his meaning also reflected his admission that climate models are “low resolution” relative to weather forecasting models. Or maybe he was referencing longer-term outcomes that are scenario-dependent. Nevertheless, the quote is revealing to the extent that one would hope these models are well-calibrated to initial conditions. That is seldom the case, however.

As a modeler, I must comment on a point made by Rogers about the use of ensembles of models. That essentially means averaging the predictions of multiple models that differ in structure. Rogers denigrates the approach, and while it is agnostic with respect to theories of the underlying process generating the data, it certainly has its uses in forecasting. Averaging the predictions of two different models with statistically independent and unbiased predictions will generally produce more accurate forecasts than the individual models. Rogers may or may not be aware of this, but he has my sympathies in this case because the IPCC is averaging across a large number of models that are clearly biased in the same direction! Rogers adds this interesting tidbit on the IPCC’s use of model ensembles:

“There is a political reason for using ensembles. In order to receive the benefits flowing from predicting a climate catastrophe, climate science must present a unified front. Dissenters have to be canceled and suppressed. If the IPCC were to select the best model, dozens of other modeling groups would be left out. They would, no doubt, form a dissenting group questioning the authority of those that gave the crown to one particular model.”

Rogers discusses one more aspect of the underpinnings of climate models, one that I’ve covered several times on this blog. That is the extent to which historical climate data is either completely lacking, plagued by discontinuities or coverage, or distorted by imperfections in measurement. The data used to calibrate climate models has been manipulated, adjusted, infilled, and estimated over lengthy periods by various parties to produce “official” and unofficial temperature series. While these efforts might seem valiant as exercises in understanding the past, they are fraught with uncertainty. Rogers provides a link to the realclimatescience blog, which details many of the data shortcomings as well as shenanigans perpetrated by researchers and agencies who have massaged, imputed, or outright created these historical data sets out of whole cloth. Rogers aptly notes:

“The purported climate catastrophe ahead is 100% junk science. If the unlikely climate catastrophe actually happens, it will be coincidental that it was predicted by climate scientists. Most of the supporting evidence is fabricated.”

Paris Climate Dance: a Concon

Ah, Paris, we bid you adieu. For both scientific and economic reasons, the Paris Climate Accord is pure numbskullery. We should all be grateful that President Trump has decided to revoke the expensive promises made by Barack Obama under the agreement in a willful effort to appease the world’s rent seekers.

From a scientific perspective, the accord’s prescriptions are premised on a partial effect: absent any feedbacks, carbon emissions would raise the atmospheric temperature slightly. But feedback effects are massively important, as anyone familiar with the climate models’ terrible track record of predictive performance might guess. Water vapor, cloud formation, wind currents, and the response of the Earth’s biomass are just some of the effects that impinge on the relationship between atmospheric carbon and temperatures. In addition, carbon forcings are relatively minor compared to the energy impulses delivered by natural sources, including solar activity and the Earth’s varying axial tilt. Paleoclimate data shows that the world has been this warm before, and warmer.

The economic case against the Paris Accord is even stronger. The very idea that authorities would impose huge material sacrifices on mankind in an effort to prevent a threat for which the evidence is so weak should give pause to any rational individual. Beyond that, however, the real function of the accord was not so much carbon mitigation as it was a shift in the distribution of wealth. This quote of Steven Allen, in a scathing assessment of the agreement, is instructive (forgive his mid-sentence switch to sarcasm):

“Mainly, it’s about taking money from taxpayers and consumers and businesspeople and electricity ratepayers and giving it to crony capitalists, and taking money from people in relatively successful countries and giving that money to rich people in poor countries, to the benefit of members of governing elites who support the Paris deal for the good of humanity and not at all because they expect to line their pockets with it.“

World carbon emissions were expected to keep rising at least through 2030 under the agreement. The subsidies it promised to crony capitalists in the renewable energy industry were to generously fund technologies that are not economically viable without government support, to the detriment of relatively clean-burning fossil fuels, not to mention nuclear power. The U.S. promised to reduce absolute carbon emissions, but the world’s greatest emitter of carbon dioxide, China, promised only to seek to limit emissions per unit of GDP, but not until sometime down the road. That means China’s level of emissions might not reverse, given the rapid growth of the Chinese economy. India’s commitment is similar. And Russia promised a reduction relative to a depressed 1990 level of emissions, which means they have plenty of room for growth.

As for the U.S., where absolute carbon emissions have been decreasing since 2007, the Paris Accord relied on so-called “voluntary” limits to be imposed by federal mandates. Financial demands were made by developing countries under the deal: $100 billion per year. And who would pay for that? Taxpayers in the developed countries, of course. One can only imagine the lust of unaccountable third-world officialdom for those funds. Thus far, the U.S. has paid only $1 billion into the so-called Green Climate Fund, and at least half of that was taken from a State Department account from which disbursal did not require Congressional approval.

Jeffrey Tucker, who is anything but a fan of Donald Trump, minced no words in his assessment of the Paris “treaty”. Here are a few selected quotes:

“The Paris Agreement is a ‘voluntary’ agreement because its architects knew it would never pass the US Senate as a treaty. Why? Because the idea of the agreement is that the US government’s regulatory agencies would impose extreme mandates on its energy sector: how it should work, what kinds of emissions it should produce, the best ways to power our lives (read: not fossil fuels), and hand over to developing world regimes billions and even trillions of dollars in aid, a direct and ongoing forcible transfer of wealth from American taxpayers to regimes all over the world, at the expense of American freedom and prosperity. …

The exuberant spokespeople talked about how ‘the United States’ had ‘agreed’ to ‘curb its emissions’ and ‘fund’ the building of fossil-free sectors all over the world. It was strange because the ‘United States’ had not in fact agreed to anything: not a single voter, worker, owner, or citizen. Not even the House or Senate were involved. This was entirely an elite undertaking to manage property they did not own and lives that were not theirs to control. …

The Paris Agreement is no different in its epistemological conceit than Obamacare, the war on drugs, nation-building, universal schooling, or socialism itself. They are all attempts to subvert the capacity of society to manage itself on behalf of the deluded dreams of a few people with power and their lust for controlling social and economic outcomes.“

The popular fascination with climate scare stories has provided a useful channel of influence for would-be central planners and redistributionists. These social dementors reject the proposition that science is a process of continuing challenge and testing, thereby subverting the very notion of scientific inquiry. They make the laughable claim that 170 years of temperature data, much of which is quite sketchy, is sufficient to draw strong conclusions about the trends and dynamics of the climate on a four billion year-old planet.

Even worse, the climate alarmists insist that they have a monopoly on scientific knowledge, despite a significant share of skeptics in the climate science community. But in pursuit of that monopoly, the alarmists have gone so far as to undermine the integrity of the peer review process in the climate literature and to manipulate temperature data to exaggerate recent records. They have promoted the false claims that cyclonic storm energy has increased with carbon concentration and that sea levels are rising at an increasing rate. (Coastal property values don’t seem to reflect those concerns.) They would have us confuse actual climate data with model predictions, and they continue to offer prescriptions based on carbon-forcing models after many years of terrible forecast performance. They claim that a small increment (one part per 10,000) to the concentration of a trace atmospheric gas will dominate other forces exerting far greater variations in energy. They ignore the benefits that an increase in nourishing carbon dioxide and warming can provide. And they make the anthropocentric claim that a costly sacrifice by mankind, in an attempt to reduce that trace gas slightly if at all, will pay off reliably by reducing global temperatures, despite the very modest claims on those grounds by the Paris Accord itself.

Here is a link to 17 earlier posts on Sacred Cow Chips having to do with the hypothesis of anthropomorphic global warming, including this one written in late 2015, at the time of the Paris Climate Summit.

Playing Pretend Science Over Cocktails

It’s a great irony that our educated and affluent classes have been largely zombified on the subject of climate change. Their brainwashing by the mainstream media has been so effective that these individuals are unwilling to consider more nuanced discussions of the consequences of higher atmospheric carbon concentrations, or any scientific evidence to suggest contrary views. I recently attended a party at which I witnessed several exchanges on the topic. It was apparent that these individuals are conditioned to accept a set of premises while lacking real familiarity with supporting evidence. Except in one brief instance, I avoided engaging on the topic, despite my bemusement. After all, I was there to party, and I did!

The zombie alarmists express their views within a self-reinforcing echo chamber, reacting to each others’ virtue signals with knowing sarcasm. They also seem eager to avoid any “denialist” stigma associated with a contrary view, so there is a sinister undercurrent to the whole dynamic. These individuals are incapable of citing real sources and evidence; they cite anecdotes or general “news-say” at best. They confuse local weather with climate change. Most of them haven’t the faintest idea how to find real research support for their position, even with powerful search engines at their disposal. Of course, the search engines themselves are programmed to prioritize the very media outlets that profit from climate scare-mongering. Catastrophe sells! Those media outlets, in turn, are eager to quote the views of researchers in government who profit from alarmism in the form of expanding programs and regulatory authority, as well as researchers outside of government who profit from government grant-making authority.

The Con in the “Consensus”

Climate alarmists take assurance in their position by repeating the false claim that 97% of climate scientists believe that human activity is the primary cause of warming global temperatures. The basis for this strong assertion comes from an academic paper that reviewed other papers, the selection of which was subject to bias. The 97% figure was not a share of “scientists”. It was the share of the selected papers stating agreement with the anthropomorphic global warming (AGW) hypothesis. And that figure is subject to other doubts, in addition to the selection bias noted above: the categorization into agree/disagree groups was made by “researchers” who were, in fact, environmental activists, who counted several papers written by so-called “skeptics” among the set that agreed with the strong AGW hypothesis. So the “97% of scientists” claim is a distortion of the actual findings, and the findings themselves are subject to severe methodological shortcomings. On the other hand, there are a number of widely-recognized, natural reasons for climate change, as documented in this note on 240 papers published over just the first six months of 2016.

Data Integrity

It’s rare to meet a climate alarmist with any knowledge of how temperature data is actually collected. What exactly is the “global temperature”, and how can it be measured? It is a difficult undertaking, and it wasn’t until 1979 that it could be done with any reliability. According to Roy Spencer, that’s when satellite equipment began measuring:

“… the natural microwave thermal emissions from oxygen in the atmosphere. The intensity of the signals these microwave radiometers measure at different microwave frequencies is directly proportional to the temperature of different, deep layers of the atmosphere.“

Prior to the deployment of weather satellites, and starting around 1850, temperature records came only from surface temperature readings. These are taken at weather stations on land and collected at sea, and they are subject to quality issues that are generally unappreciated. Weather stations are unevenly distributed and they come and go over time; many of them produce readings that are increasingly biased upward by urbanization. Sea surface temperatures are collected in different ways with varying implications for temperature trends. Aggregating these records over time and geography is a hazardous undertaking, and these records are, unfortunately, the most vulnerable to manipulation.

The urbanization bias in surface temperatures is significant. According to this paper by Ross McKitrick, the number of weather stations counted in the three major global temperature series declined by more than 4,500 since the 1970s (over 75%), and most of those losses were rural stations. From McKitrick’s abstract:

“The collapse of the sample size has increased the relative fraction of data coming from airports to about 50% (up from about 30% in the late 1970s). It has also reduced the average latitude of source data and removed relatively more high altitude monitoring sites. Oceanic data are based on sea surface temperature (SST) instead of marine air temperature (MAT)…. Ship-based readings changed over the 20th century from bucket-and-thermometer to engine-intake methods, leading to a warm bias as the new readings displaced the old.“

Think about that the next time you hear about temperature records, especially NOAA reports on a “new warmest month on record”.

Data Manipulation

It’s rare to find alarmists having any awareness of the scandal at East Anglia University, which involved data falsification by prominent members of the climate change “establishment”. That scandal also shed light on corruption of the peer-review process in climate research, including a bias against publishing work skeptical of the accepted AGW narrative. Few are aware now of a very recent scandal involving manipulation of temperature data at NOAA in which retroactive adjustments were applied in an effort to make the past look cooler and more recent temperatures warmer. There is currently an FOIA outstanding for communications between the Obama White House and a key scientist involved in the scandal. Here are Judith Curry’s thoughts on the NOAA temperature manipulation.

Think about all that the next time you hear about temperature records, especially NOAA reports on a “new warmest month on record”.

Other Warming Whoppers

Last week on social media, I noticed a woman emoting about the way hurricanes used to frighten her late mother. This woman was sharing an article about the presumed negative psychological effects that climate change was having on the general public. The bogus premises: we are experiencing an increase in the frequency and severity of storms, that climate change is causing the storms, and that people are scared to death about it! Just to be clear, I don’t think I’ve heard much in the way of real panic, and real estate prices and investment flows don’t seem to be under any real pressure. In fact, the frequency and severity of severe weather has been in decline even as atmospheric carbon concentrations have increased over the past 50 years.

I heard another laughable claim at the party: that maps are showing great areas of the globe becoming increasingly dry, mostly at low latitudes. I believe the phrase “frying” was used. That is patently false, but I believe it’s another case in which climate alarmists have confused model forecasts with fact.

The prospect of rising sea levels is another matter that concerns alarmists, who always fail to note that sea levels have been increasing for a very long time, well before carbon concentrations could have had any impact. In fact, the sea level increases in the past few centuries are a rebound from lows during the Little Ice Age, and levels are now back to where the seas were during the Medieval Warm Period. But even those fluctuations look minor by comparison to the increases in sea levels that occurred over 8,000 years ago. Sea levels are rising at a very slow rate today, so slowly that coastal construction is proceeding as if there is little if any threat to new investments. While some of this activity may be subsidized by governments through cheap flood insurance, real money is on the line, and that probably represents a better forecast of future coastal flooding than any academic study can provide.

Old Ideas Die Hard

Two enduring features of the climate debate are 1) the extent to which so-called “carbon forcing” models of climate change have erred in over-predicting global temperatures, and 2) the extent to which those errors have gone unnoticed by the media and the public. The models have been plagued by a number of issues: the climate is not a simple system. However, one basic shortcoming has to do with the existence of strong feedback effects: the alarmist community has asserted that feedbacks are positive, on balance, magnifying the warming impact of a given carbon forcing. In fact, the opposite seems to be true: second-order responses due to cloud cover, water vapor, and circulation effects are negative, on balance, at least partially offsetting the initial forcing.

Fifty Years Ain’t History

One other amazing thing about the alarmist position is an insistence that the past 50 years should be taken as a permanent trend. On a global scale, our surface temperature records are sketchy enough today, but recorded history is limited to the very recent past. There are recognized methods for estimating temperatures in the more distant past by using various temperature proxies. These are based on measurements of other natural phenomenon that are temperature-sensitive, such as ice cores, tree rings, and matter within successive sediment layers such as pollen and other organic compounds.

The proxy data has been used to create temperature estimates into the distant past. A basic finding is that the world has been this warm before, and even warmer, as recently as 1,000 years ago. This demonstrates the wide range of natural variation in the climate, and today’s global temperatures are well within that range. At the party I mentioned earlier, I was amused to hear a friend say, “Ya’ know, Greenland isn’t supposed to be green”, and he meant it! He is apparently unaware that Greenland was given that name by Viking settlers around 1000 AD, who inhabited the island during a warm spell lasting several hundred years… until it got too cold!

Carbon Is Not Poison

The alarmists take the position that carbon emissions are unequivocally bad for people and the planet. They treat carbon as if it is the equivalent of poisonous air pollution. The popular press often illustrates carbon emissions as black smoke pouring from industrial smokestacks, but like oxygen, carbon dioxide is a colorless gas and a gas upon which life itself depends.

Our planet’s vegetation thrives on carbon dioxide, and increasing carbon concentrations are promoting a “greening” of the earth. Crop yields are increasing as a result; reforestation is proceeding as well. The enhanced vegetation provides an element of climate feedback against carbon “forcings” by serving as a carbon sink, absorbing increasing amounts of carbon and converting it to oxygen.

Matt Ridley has noted one of the worst consequences of the alarmists’ carbon panic and its influence on public policy: the vast misallocation of resources toward carbon reduction, much of it dedicated to subsidies for technologies that cannot pass economic muster. Consider that those resources could be devoted to many other worthwhile purposes, like bringing electric power to third-world families who otherwise must burn dung inside their huts for heat; for that matter, perhaps the resources could be left under the control of taxpayers who can put it to the uses they value most highly. The regulatory burdens imposed by these policies on carbon-intensive industries represent lost output that can’t ever be recouped, and all in the service of goals that are of questionable value. And of course, the anti-carbon efforts almost certainly reflect a diversion of resources to the detriment of more immediate environmental concerns, such as mitigating truly toxic industrial pollutants.

The priorities underlying the alarm over climate change are severely misguided. The public should demand better evidence than consistently erroneous model predictions and manipulated climate data. Unfortunately, a media eager for drama and statism is complicit in the misleading narrative.

FYI: The cartoon at the top of this post refers to the climate blog climateaudit.org. The site’s blogger Steve McIntyre did much to debunk the “hockey stick” depiction of global temperature history, though it seems to live on in the minds of climate alarmists. McIntyre appears to be on an extended hiatus from the blog.

Carbon Farce Meets Negative Forcings

A new technology is being refined that could reverse years of carbon forcings, given sufficiently wide application, and do so at a profit. That profit should not require the kind of costly subsidies that are now routinely paid to green crony capitalists. Instead, the profit should derive from real market demand for a valuable material. The MIT Technology Review covers the technology under “… How To Suck Carbon From The Air, Make Stuff From It“. It makes possible a form of carbon capture that produces carbon nanotubes, a promising material already in use but having much wider potential. From the second link above:

“Carbon nanotubes are a great example of how useful materials are being developed. This material is said to be one hundred times stronger than steel because of its ‘molecular perfection’ as explained in the paper ‘Year 2050: Cities in the Age of Nanotechnology’ by Peter Yeadon. In addition, because carbon atoms can bond with other matter; such material can be an ‘insulator, semi-conductor or conductor of electricity’”.

Carbon nanotubes have remarkable properties that will revolutionize fabrics and allow buildings to have incredible strength, “transient features” such as variable transparency, and shape shifting. The new technology is said to be more efficient than existing methods of producing carbon nanotubes, and probably much cheaper.

The first link above quotes the developers on the technology’s massive potential for carbon capture:

“They calculate that given an area less than 10 percent of the size of the Sahara Desert, the method could remove enough carbon dioxide to make global atmospheric levels return to preindustrial levels within 10 years, even if we keep emitting the greenhouse gas at a high rate during that period.“

That area is twice the size of California, but a much more modest deployment would certainly reduce the political pressure to decrease carbon emissions. The extent would depend upon the demand for nanotubes, which is expected to grow dramatically in the presence of declining costs. Perhaps we’ll want more carbon emissions if nanotube materials come into widespread use. That would be a welcome development in the developing world, where fossil fuels hold the potential to lift millions out of poverty, as they have for advanced countries in the past. However, such a change would require elites to acknowledge and yield to the supremacy of markets over politics.

A technology capable of such significant carbon capture obviously constitutes a negative carbon “forcer”. Therefore, another implication is that climate models with a heavy emphasis on carbon forcings may be rendered moot. Those models have persistently generated over-predictions of global temperatures, so a deemphasis is already long overdue.

Another hat tip to my buddy John Crawford, who recently has fed me some great information. John should accept my invitation to guest-blog on SCC sometime soon, or start his own blog!
