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.

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.

Warm, Contented Civilizations

Human civilizations have experienced many of their worst trials during periods of cooling and cold temperatures over the past 8,000 – 10,000 years. These were episodes associated with droughts as well. Conversely, civilizations have tended to prosper during warm, wet periods. These associations between human progress and the natural environment are discussed in a pair of articles by Andy May: “Climate and Human Civilization Over the Past 18,000 Years“, and  “Climate and Human Civilization for the Past 4,000 Years“. The articles are part climate science, part history, and part anthropology, with many fascinating details.

May presents large charts that can be downloaded, and they are especially interesting to ponder. He uses historical temperature proxies from Antarctica and Greenland to construct the charts, along with more recent data on measured surface temperatures in Greenland. According to May, the proxies are highly correlated with other proxy data from less extreme latitudes. Several important takeaways are the following:

  1. Warm periods in the historical record are associated with wet conditions, and cold periods are associated with dry conditions. This is intuitive, as warm air holds more moisture than cold air.
  2. There are estimates of temperatures going back more than 800 million years; apparent cyclical regularities in temperatures have lasted as long 150 million years. Cycles within cycles are evident: a 100,000 year cycle is prominent as well as a 25,000 year cycle (see #4 below).
  3. Today’s temperatures are not as high as those prevailing during about 200 years of the so-called Roman Warm Period, or during a span of similar length in the so-called Minoan Warm Period, about 3,300 years ago. Today’s temperatures are much lower than estimates for much of the earth’s pre-human history.
  4. The southern hemisphere has more volatile temperatures than the northern hemisphere due to the tilt of the earth’s axis at perihelion in January, when the earth is closest to the sun. That means the southern hemisphere tends to have warmer summers and colder winters. That will reverse over the next 10,000 years, and then it will reverse again. There is more land mass in the north, however, so it’s not clear that less extreme weather in the north helps explain the hugely lopsided distribution of development and population in that hemisphere.
  5. Recent increases in sea levels have been small relative to the years following the Little Ice Age. Projected increases over the next 50 years are of a magnitude that should be easily manageable for most coastal areas.
  6. Atmospheric carbon concentration seems to lag major increases in temperatures by about 800 years, raising a question of causality. Today’s carbon concentration is low relative to earlier epochs; it has been increasing for thousands of years, clearly independent of human activity, and is now near 400,000 year highs.
  7. Civilizations have blossomed with warm temperatures and they have collapsed or hit extended periods of retarded progress with declines in temperatures. Human agriculture was born as temperatures rose out of the depths of a glacial period about 10,000-12,000 years ago. Rome flourished during a warm cycle and collapsed as it waned. The Vikings settled in Greenland and Newfoundland during the Medieval Warm Period and were eliminated by the Little Ice Age. May cites a number of other examples of temperature cycles bringing on major shifts in the course of human progress. There are many possible explanations for the decline of past civilizations, but extremely low temperatures, droughts, and lengthy periods of weather inhospitable to agriculture have been important.

The fashion today is to insist that only dramatic changes in our use of energy can avert a global warming catastrophe. It is not clear that any effort by humans to manipulate global temperatures can overcome the natural forces that are always driving temperature change. For that matter, it is not clear that carbon dioxide is a bad thing, or that diverting vast quantities of resources to reduce it would be wise. CO2 is certainly not a pollutant in the normal sense of the word. Here is an excerpt from May’s conclusion in his “4,000 years” article, which speaks volumes:

“First, there is no perfect temperature. Man, even in pre-industrial times, adapted to a variety of temperatures and he has always done better in warm times and worse in cold times. Second, why would anyone want to go back to the pre-industrial climate? The Washington Post says the goal of the Paris Climate Conference was get the world to agree to limit global warming to less than two degrees above pre-industrial temperatures. Pre-industrial times? That’s the Little Ice Age, when it snowed in July, a time of endless war, famine and plague. According to the Greenland ice core proxy data, temperatures 180 years ago were nearly the coldest seen since the end of the last glacial period 10,000 years ago! Why measure our success in combating anthropogenic warming, if there is any such thing, from such an unusually cold time?“

MovieDisaster

In the imagination of the climate alarmist, almost everything portends an approaching catastrophe. A hurricane? Tornado? Draught? Warm spell? Cold spell? Blizzard? Bad harvest? To their way of thinking, these are all signs that CO2 is damaging the climate. Obviously, these are weather events that imply nothing in the absence of corroborating evidence, though you wouldn’t know it from listening to the precaution pols. Warren Meyer at Coyote Blog has posted another in his series of essays on this topic, this time called “Are We Already Seeing Climate Change?” He provides links to the earlier installments — all interesting. In this installment, he covers five topics under the heading “Manufacturing A Sense that the Climate Is Broken”, which I think would have made a better title for his post. I’ll try to summarize the five points briefly, but do read the whole thing:

Publication Bias:  This quote speaks for itself: “Every single tail-of-the-distribution weather event from around the world is breathlessly reported, leaving the impression among viewers that more such events are occurring, even when there is in fact no such trend. Further, since weather events can drive media ratings, there is an incentive to make them seem scarier.”

Claiming a Trend From One Data Point: This is the kind of error to which I alluded in the first paragraph. Think of Al Gore’s reaction to Hurricane Katrina. The charts offered by Meyer in this section are very nice. There is no upward trend in any of the following: hurricane energy; severe tornadic activity; the incidence of draughts or draught severity; heat waves; extremely hot days; and there is no abatement in the upward trend in crop yields. In fact, there is no trend in high temperature records in the U.S. The upward trend in average surface temperatures in the U.S. is entirely due to warmer nighttime temperatures.

Measurement Technology Bias: We now have the technology to measure various aspects of the climate from space. We can track polar ice extent with much more precision. Doppler radar technology and weather chasers have helped to identify more small tornados than we’d have known of 50 years ago. But when events seem noteworthy to alarmists, they draw extreme conclusions. To their great chagrin, these phenomena are often products of our enhanced ability to measure things.

What Is Normal?: This is related to measurement bias. Our detailed records on surface temperatures go back about 150 years, which is an extremely short slice of history. Temperature proxies from earlier eras, such as ice cores and fossilized tree rings, tell us that the recent past is not all that unusual. Moreover, we also know that glacier melting and sea level increases have been happening for much longer than the buildup of CO2. Those trends began near the end of the “Little Age Age”, around 1800. And there is evidence that these types of developments have happened before. Alarmists, however, assume that what we’ve witnessed in the recent past is unprecedented.

Collapsing Causality in a Complex System To a Single Variable:  “With all the vast complexity of the climate, are we really to believe that every unusual weather event is caused by a 0.013 percentage point change (270 ppm to 400 ppm) in the concentration of one atmospheric gas?” Not likely! Here Meyer helps put the recent temperature trends in perspective: they are tiny relative to their annual variation, which occurs both across seasons and within days.

The public seems to regard the co-called climate catastrophe with more skepticism today than perhaps ten years ago. Not only do the facts contradict the dire predictions of carbon-forcing climate models and alarmist scare stories, but people also recognize that the costs of attempting to avoid a global warming trend are massive and, well, probably not worth it. Moreover, they rightly suspect unworthy political motives in the alarmist community. If some carbon-induced warming is an eventuality, and that’s an “if”, it might well prove to be beneficial for people and the planet. Relax!

 

Climate Alarmists Warm To Speech Control

AGW-cartoon

The reactionaries in the global warming plunderbund are revealing their philosophical bankruptcy, dishonesty, and inner fascism. Science is a continuous process of learning through empirical observation, theory and testing. Refutation is as important to the process as original research and replication. Experimental results can be confirmed, but theory can never be established as absolute fact. The term “settled science” is very nearly an oxymoron, yet we constantly hear that climate science is “settled”. Nothing could be further from the truth.

We are asked by the warmists to accept sweeping conclusions on the basis of an extremely short historical record, one that is clouded by sharp disputes over measurement issues. The long-term record based on temperature proxies shows that recent trends are well within the range of natural variability. We are asked to accept conclusions based largely on models that have proven to be extremely inaccurate and that fail to account for important climate influences such as solar variation and oceanic cycles. And with essentially no historical justification, we are asked to accept assumptions about what global temperatures “should be”, and that we should make drastic sacrifices in a quixotic effort to make temperatures stay put. To do so, we are asked to divert resources on a massive scale to mitigate a risk that is speculative at best. An alternative view is that mankind should make sacrifices in order to adapt to change when it occurs, rather than taking the arrogant view that we can, with sufficient coercion and manipulation of private decisions, dominate natural forces to assure climate stability.

Warren Meyer at Coyote Blog has an excellent series of posts on climate change. The most recent of those posts is on natural attribution of climate change. It includes links to earlier parts of his series. Meyer compares today’s alarmists to a hypothetical observer predicting future temperatures in the year 1600, roughly the minimum of the “mini ice-age”. Of course, that observer would have said it would get colder based on his experience, but that would have been wrong. Today’s alarmists rest their case on a 20-year uptrend between 1978 and 1998, tying it to man-made carbon dioxide emissions. In fact, a longer-term view shows that surface temperatures had increased in similar spurts before carbon emissions were a factor of any kind.

Scoundrels tend to twist facts when the facts don’t support their view. Rick Moran reports on an academic paper concluding that it’s acceptable to lie about the threat posed by climate change. It’s not enough to present research and the full range of uncertainty surrounding forecasts, which is very wide. No, the reporting must be wrapped in a sort of Grimm’s fairy tale in order to teach the public a lesson, unschooled children that they are. Such is the manipulative nature of the warmist community.

And the dishonesty is extensive. Remember the claim that 97% of climate scientists accept the proposition of man-made global warming? It was debunked in short order, but the media seemingly can’t get enough of a disaster scenario, so the claim lives on. Famed climatologist Judith Curry has a number of posts on her blog explaining the misleading details of this bit of disinformation. Among the problems of methodology and reporting of this “survey” result is that it was not based on an actual survey of scientists. Instead, it rated abstracts of publications as to their consistency with particular views of the anthropomorphic global warming (AGW) proposition. Not only does this method double-count the views of individual scientists; the authors were highly selective about which scientists and how many of their publications were counted. Even more interestingly, the criteria were so loose that abstracts written by certain scientists known to be skeptical of AGW were counted within the 97%! In one of Curry’s posts, entitled “The Conceits of Consensus“, she discusses the weaknesses and refutations of the claim of a strong consensus, including the participation of non-scientist evaluators of research abstracts in the sample:

“Bottom line: inflating the numbers of ‘climate scientists’ in such surveys attempts to hide that there is a serious scientific debate about the detection and attribution of recent warming, and that scientists who are skeptical of the IPCC consensus conclusion are disproportionately expert in the area of climate change detection and attribution.“

Other studies have found that a majority of surveyed meteorologists (see here and here), geoscientists and engineers are skeptical of AGW. But again, this information is essentially ignored by the media and self-interested politicos because it does not support the crisis narrative that dictates coercive action by government.

Apparently, propaganda in support of the increasingly dubious warmist position must be reinforced by more drastic measures. Prominent leftists in government are asking whether disputing climate change is punishable under the law. You read that right! Two state attorneys general have threatened to prosecute ExxonMobil for allegedly misleading investors and the public about climate change. Senator Sheldon Whitehouse (D-RI) has proposed using RICO organized crime law to go after certain energy companies for climate change “denial”. Loretta Lynch, the U.S. Attorney General, has asked the FBI to look into it. To hell with freedom of speech. To hell with the spirit of free scientific inquiry. Your authoritarian masters insist that you must fall into line with their climate change agenda or else!

Josh Gelernter opens his recent discussion of this tyrannical gambit this way:

“Four hundred years ago this week, the Inquisition met in Rome to discuss Galileo’s support for the Copernican model of the cosmos, which placed the Sun at the center of the solar system. After five days of deliberation, a commission of inquisitors ruled that heliocentrism was ‘foolish and absurd in philosophy, and formally heretical since it explicitly contradicts in many places the sense of the Holy Scripture.’ Not a good moment for the Church. Two days later, Galileo was summoned to the Vatican and ordered ‘to abstain completely from teaching or defending this doctrine and opinion or from discussing it . . . to abandon it completely . . . and henceforth not to hold, teach, or defend it in any way whatever, either orally or in writing.’“

To underscore the hypocrisy of these threats of prosecution, David French observes that there are many other instances in which the public has been misled while the presumed climate mavens profited from the hysteria. Could these opportunistic ploys also be subject to prosecution?:

  • Al Gore insisted ten years ago that by now we’d suffer a “climate doomsday” if we failed to take the measures he advocated;
  • Perhaps ABC/Walt Disney has profited from its breathless warnings that “in 2015 milk would cost almost $13 a gallon, gas would be more than $9 a gallon, ‘flames [would] cover hundreds of square miles,’ one billion people would be malnourished, and Manhattan would be flooding — all because of climate change.“
  • The Chairman of the United Nations Intergovernmental Panel on Climate Change (IPCC) said, “If there’s no action before 2012, that’s too late….” And as French says: “The IPCC has received tens of millions of dollars while hyping the threat of global warming.“

French’s suggestions are not entirely tongue-in-cheek. These suggestions are no more outlandish than threats to prosecute anyone else over a legitimate dispute in scientific debate.

The AGW community suffers from a weak understanding of the philosophy of science, a dishonest presentation of the facts, and a tyrannical streak that should can only be tamed by stripping them of power. First, however, the voting public must wise up to the danger to our economic well being and our freedom posed by these fascist activists.

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

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

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

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

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

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

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

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

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

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

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

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

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

Climate Negotiators To Discuss Economic Cannibalism

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

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

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

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

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

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

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

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

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

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

Pollution Chart

Here is his description of the chart:

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

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

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

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

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

A Cooked-Up Climate Consensus

Settled-Science

Consensus: the world is flat; the science is settled. Consensus: the earth is at the center of the universe; the science is settled. Consensus: bloodletting can cure diseases; the science is settled. Did these ideas truly represent scientific consensus? They probably thought so at the time, but it’s more likely that they derived from long- and widely-held assumptions that had never been tested adequately via scientific methods. It might have been difficult, if not impossible, to test those propositions using the methods available at the time. There are certainly other examples of  “settled science” that were later revised, such as certain aspects of Newtonian physics.

The so-called “consensus” on climate change is similar to the first few “scientistic” assertions above, except that it’s a much less honest mistake. The most prominent claim about it is that 97% of climate scientists agree that humans have contributed to global warming. That is incorrect in several ways. Its genesis is a 2013 paper by John Cook of the University of Queensland. Richard Tol of the University of Sussex examines the facts surrounding the Cook paper in “Global warming consensus claim does not stand up“. The claim itself is a misrepresentation of Cook’s findings, according to Tol:

“The 97% refers to the number of papers, rather than the number of scientists. The alleged consensus is about any human role in climate change, rather than a dominant role….“

It is well known that the peer review process in the climate research community was fundamentally corrupt during the period covered by Cook’s examination of the literature. Papers submitted to academic journals by climate “dissenters” were often shut out, which would have biased Cook’s findings even if his review had been conducted honestly. Tol goes on to note the distortions introduced by Cook’s research, including a non-representative sample of papers:

“The sample was padded with irrelevant papers. An article about TV coverage on global warming was taken as evidence for global warming. In fact, about three-quarters of the papers counted as endorsements had nothing to say about the subject matter.“

It gets even worse:

“Cook enlisted a small group of environmental activists to rate the claims made by the selected papers. Cook claims that the ratings were done independently, but the raters freely discussed their work. There are systematic differences between the raters. Reading the same abstracts, the raters reached remarkably different conclusions – and some raters all too often erred in the same direction. Cook’s hand-picked raters disagreed what a paper was about 33% of the time. In 63% of cases, they disagreed about the message of a paper with the authors of that paper.“

On top of all that, Cook was uncooperative when asked to make his data available to other researchers. Apparently a hacker obtained the data, which revealed a highly questionable data collection process (and that Cook had lied regarding the existence of time stamps on the surveys):

“After collecting data for 8 weeks, there were 4 weeks of data analysis, followed by 3 more weeks of data collection. The same people collected and analysed the data. After more analysis, the paper classification scheme was changed and yet more data collected.“

In short, the Cook research upon which the 97% claim is based is trash. There are a number of points upon which climate researchers can largely agree in principle, including the fact that greenhouse gases would warm the planet, but only if ceteris paribus is invoked. There are many feedback effects and confounding influences that change the relationship, and the actual time span of data that can be brought to bear on the issue is strikingly short to justify bold conclusions. Unfortunately, the research environment is so politicized that even the data itself is subject to manipulation. Astonishingly, many assertions about the actual climate are, in fact, based on model output, not actual data!

There is strong disagreement at the highest levels of the scientific community regarding the balance of the evidence on climate change and whether it justifies radical policy change. Matt Ridley examines this issue in “The Climate Wars’ Damage To Science“:

“Today’s climate science, as Ian Plimer points out in his chapter in The Facts, is based on a ‘pre-ordained conclusion, huge bodies of evidence are ignored and analytical procedures are treated as evidence’. Funds are not available to investigate alternative theories. Those who express even the mildest doubts about dangerous climate change are ostracised, accused of being in the pay of fossil-fuel interests or starved of funds; those who take money from green pressure groups and make wildly exaggerated statements are showered with rewards and treated by the media as neutral.“

Ridley goes on to recount the litany of scandals that have erupted within the climate establishment over the past few years. It is well worth reading, but ultimately these developments can’t help but damage science, its reputation with the public, and its usefulness to mankind.

Fitting Data To Models At NOAA

Dilbert Made Up Numbers

If the facts don’t suit your agenda, change them! The 18-year “hiatus” in global warming, which has made a shambles of climate model predictions, is now said to have been based on “incorrect data”, according to researchers at National Oceanic and Atmospheric Administration (NOAA). Translation: they have created new data “adjustments” that tell a story more consistent with their preferred narrative, namely, that man-made carbon emissions are forcing global temperatures upward, more or less steadily. The New York Times’ report on the research took a fairly uncritical tone, despite immediate cautions and rebuttals from a number of authorities. On balance, the NOAA claims seem rather laughable.

Ross McKitrick has an excellent discussion of the NOAA adjustments on the Watts Up With That? blog (WUWT). His post reinforces the difficulty of aggregating temperature data in a meaningful way. A given thermometer in a fixed location can yield drifting temperatures over time due to changes in the surrounding environment, such as urbanization. In addition, weather stations are dispersed in irregular ways with extremely uneven coverage, and even worse, they have come and gone over time. There are gaps in the data that must be filled. There might be international differences in reporting practices as well. Sea surface temperature measurement is subject to even greater uncertainty. They can be broadly classified into temperatures collected on buoys and those collected by ships, and the latter have been taken in a variety of ways, from samples collected in various kinds of buckets, hull sensors, engine room intakes, and deck temperatures. The satellite readings, which are a recent development, are accurate in tracking changes, but the levels must be calibrated to other data. Here’s McKitrick on the measurements taken on ships:

“… in about half the cases people did not record which method was used to take the sample (Hirahari et al. 2014). In some cases they noted that, for example, ERI readings were obtained but they not indicate the depth. Or they might not record the height of the ship when the MAT reading is taken.“

The upshot is that calculating a global mean temperature is a statistical exercise fraught with uncertainty. A calculated mean at any point in time is an estimate of a conceptual value. The estimate is one of many possible estimates around the “true” value. Given the measurement difficulties, any meaningful confidence interval for the true mean would likely be so broad as to render inconsequential the much-discussed temperature trends of the past 50 years.

McKitrick emphasizes the three major changes made by NOAA, all having to do with sea surface temperatures:

  1. NOAA has decided to apply an upward adjustment to bring buoy temperature records into line with ship temperatures. This is curious, because most researchers have concluded that the ship temperatures are subject to greater bias. Also, the frequency of buoy records has been rising as a share of total sea temperature readings.
  2. NOAA added extra weight to the buoy readings, a decision which was unexplained.
  3. They applied a relatively large downward adjustment to temperatures collected by ships during 1998-2000.

Even the difference between the temperatures measured by ships and buoys (0.12 degrees Celsius), taken at face value, has a confidence interval (95%?) that is about 29 times as large as the difference. That adjustments such as those above are made with a straight face is nothing short of preposterous.

A number of other researchers have weighed in on the NOAA adjustments. Carl Beisner summarizes some of this work. He quotes McKitrick as well as Judith Curry:

“I think that uncertainties in global surface temperature anomalies is [sic] substantially understated. The surface temperature data sets that I have confidence in are the UK group and also Berkeley Earth. This short paper in Science is not adequate to explain and explore the very large changes that have been made to the NOAA data set. The global surface temperature datasets are clearly a moving target.“

There are a number of other posts this week on WUWT regarding the NOAA adjustments. Some of the experts, like Judith Curry, emphasize the new disparities created by NOAA’s adjustments with other well-regarded temperature series. It will be interesting to see how these differences are debated. Let’s hope that the discussion is driven wholly by science and not politics, but I fear that the latter will have a major impact on the debate. It has already.

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

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

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

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

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

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

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