Conformity and Suppression: How Science Is Not “Done”

I’m not terribly surprised to learn that scientific advancement has slowed over my lifetime. A recent study published in the journal Nature documented a secular decline in the frequency of “disruptive” or “breakthrough” scientific research across a range of fields. Research has become increasingly dominated by “incremental” findings, according to the authors. The graphic below tells a pretty dramatic story:

The index values used in the chart range “from 1 for the most disruptive to -1 for the least disruptive.” The methodology used to assign these values, which summarize academic papers as well as patents, produces a few oddities. Why, for example, does the tech revolution of the last 40 years create barely a blip in the technology index in the chart above? And why have tech research and social science research always been more “disruptive” than other fields of study?

Putting those questions aside, the Nature paper finds trends that are basically consistent across all fields. Apparently, systematic forces have led to declines in these measures of breakthrough scientific findings. The authors try to provide a few explanations as to the forces at play: fewer researchers, incrementalism, and a growing role of large-team research that induces conformity. But if research has become more incremental, that’s more accurately described as a manifestation of the disease, rather than a cause.

Conformity

Steven F. Hayward skewers the authors a little, and perhaps unfairly, stating a concern held by many skeptics of current scientific practices. Hayward says the paper:

“… avoids the most significant and obvious explanation with the myopia of Inspector Clouseau, which is the deadly confluence of ideology and the increasingly narrow conformism of academic specialties.”

Conformism in science is nothing new, and it has often interfered with the advancement of knowledge. The earliest cases of suppression of controversial science were motivated by religious doctrine, but challenges to almost any scientific “consensus” seem to be looked upon as heresy. Several early cases of suppression are discussed here. Matt Ridley has described the case of Mary Worley Montagu, who visited Ottoman Turkey in the early 1700s and witnessed the application of puss from smallpox blisters to small scratches on the skin of healthy subjects. The mild illness this induced led to immunity, but the British medical establishment ridiculed her. A similar fate was suffered by a Boston physician in 1721. Ridley says:

“Conformity is the enemy of scientific progress, which depends on disagreement and challenge. Science is the belief in the ignorance of experts, as [the physicist Richard] Feynman put it.”

When was the Scientific Boom?

I couldn’t agree more with Hayward and Ridley on the damaging effects of conformity. But what gave rise to our recent slide into scientific conformity, and when did it begin? The Nature study on disruptive science used data on papers and patents starting in 1945. The peak year for disruptive science within the data set was … 1945, but the index values were relatively high over the first two decades of the data set. Maybe those decades were very special for science, with a variety of applications and high-profile accomplishments that have gone unmatched since. As Scott Sumner says in an otherwise unrelated post, in many ways we’ve failed to live up to our own expectations:

“In retrospect, the 1950s seem like a pivotal decade. The Boeing 707, nuclear power plants, satellites orbiting Earth, glass walled skyscrapers, etc., all seemed radically different from the world of the 1890s. In contrast, airliners of the 2020s look roughly like the 707, we seem even less able to build nuclear power plants than in the 1960s, we seem to have a harder time getting back to the moon than going the first time, and we still build boring glass walled skyscrapers.”

It’s difficult to put the initial levels of the “disruptiveness” indices into historical context. We don’t know whether science was even more disruptive prior to 1945, or how the indices used by the authors of the Nature article would have captured it. And it’s impossible to say whether there is some “normal” level of disruptive research. Is a “normal” index value equal to zero, which we now approach as an asymptote?

Some incredible scientific breakthroughs occurred decades before 1945, to take Einstein’s theory of relativity as an obvious example. Perhaps the index value for physical sciences would have been much higher at that time, were it measured. Whether the immediate post-World War II era represented an all-time high in scientific disruption is anyone’s guess. Presumably, the world is always coming from a more primitive base of knowledge. Discoveries, however, usually lead to new and deeper questions. The authors of the Nature article acknowledge and attempt to test for the “burden” of a growing knowledge base on the productivity of subsequent research and find no effect. Nevertheless, it’s possible that the declining pattern after 1945 represents a natural decay following major “paradigm shifts” in the early twentieth century.

The Psychosis Now Known As “Wokeness”

The Nature study used papers and patents only through 2010. Therefore, the decline in disruptive science predates the revolution in “wokeness” we’ve seen over the past decade. But “wokeness” amounts to a radicalization of various doctrines that have been knocking around for years. The rise of social justice activism, critical theory, and anthropomorphic global warming theology all began long before the turn of the century and had far reaching effects that extended to the sciences. The recency of “wokeness” certainly doesn’t invalidate Hayward and Ridley when they note that ideology has a negative impact on research productivity. It’s likely, however, that some fields of study are relatively immune to the effects of politicization, such as the physical sciences. Surely other fields are more vulnerable, like the social sciences.

Citations: Not What They Used To Be?

There are other possible causes of the decline in disruptive science as measured by the Nature study, though the authors believe they’ve tested and found these explanations lacking. It’s possible that an increase in collaborative work led to a change in citation practices. For example, this study found that while self-citation has remained stable, citation of those within an author’s “collaboration network” has declined over time. Another paper identified a trend toward citing review articles in Ecology Journals rather than the research upon which those reviews were based, resulting in incorrect attribution of ideas and findings. That would directly reduce the measured “disruptiveness” of a given paper, but it’s not clear whether that trend extends to other fields.

Believe it or not, “citation politics” is a thing! It reflects the extent to which a researcher should suck-up to prominent authors in a field of study, or to anyone else who might be deemed potentially helpful or harmful. In a development that speaks volumes about trends in research productivity, authors are now urged to append a “Citation Diversity Statement” to their papers. Here’s an academic piece addressing the subject of “gendered citation practices” in contemporary physics. The 11 authors of this paper would do well to spend more time thinking about problems in physics than in obsessing about whether their world is “unfair”.

Science and the State

None of those other explanations are to disavow my strong feeling that science has been politicized and that it is harming our progress toward a better world. In fact, it usually leads us astray. Perhaps the most egregious example of politicized conformism today is climate science, though the health sciences went headlong toward a distinctly unhealthy conformism during the pandemic (and see this for a dark laugh).

Politicized science leads to both conformism and suppression. Here are several channels through which politicization might create these perverse tendencies and reduce research productivity or disruptiveness:

  • Political or agenda-driven research is driven by subjective criteria, rather than objective inquiry and even-handed empiricism
  • Research funding via private or public grants is often contingent upon whether the research can be expected to support the objectives of the funding NGOs, agencies, or regulators. The gravy train is reserved for those who support the “correct” scientific narrative
  • Promotion or tenure decisions may be sensitive to the political implications of research
  • Government agencies have been known to block access to databases funded by taxpayers when a scientist wishes to investigate the “wrong questions”
  • Journals and referees have political biases that may influence the acceptance of research submissions, which in turn influences the research itself
  • The favorability of coverage by a politicized media influences researchers, who are sensitive to the damage the media can do to one’s reputation
  • The influence of government agencies on media treatment of scientific discussion has proven to be a potent force
  • The chance that one’s research might have a public policy impact is heavily influenced by politics
  • The talent sought and/or attracted to various fields may be diminished by the primacy of political considerations. Indoctrinated young activists generally aren’t the material from which objective scientists are made

Conclusion

In fairness, there is a great deal of wonderful science being conducted these days, despite the claims appearing in the Nature piece and the politicized corruption undermining good science in certain fields. Tremendous breakthroughs are taking place in areas of medical research such as cancer immunotherapy and diabetes treatment. Fusion energy is inching closer to a reality. Space research is moving forward at a tremendous pace in both the public and private spheres, despite NASA’s clumsiness.

I’m sure there are several causes for the 70-year decline in scientific “disruptiveness” measured in the article in Nature. Part of that decline might have been a natural consequence of coming off an early twentieth-century burst of scientific breakthroughs. There might be other clues related to changes in citation practices. However, politicization has become a huge burden on scientific progress over the past decade. The most awful consequences of this trend include a huge misallocation of resources from industrial planning predicated on politicized science, and a meaningful loss of lives owing to the blind acceptance of draconian health policies during the Covid pandemic. When guided by the state or politics, what passes for science is often no better than scientism. There are, however, even in climate science and public health disciplines, many great scientists who continue to test and challenge the orthodoxy. We need more of them!

I leave you with a few words from President Dwight Eisenhower’s Farewell Address in 1961, in which he foresaw issues related to the federal funding of scientific research:

“Akin to, and largely responsible for the sweeping changes in our industrial-military posture, has been the technological revolution during recent decades.

In this revolution, research has become central; it also becomes more formalized, complex, and costly. A steadily increasing share is conducted for, by, or at the direction of, the Federal government.

Today, the solitary inventor, tinkering in his shop, has been over shadowed by task forces of scientists in laboratories and testing fields. In the same fashion, the free university, historically the fountainhead of free ideas and scientific discovery, has experienced a revolution in the conduct of research. Partly because of the huge costs involved, a government contract becomes virtually a substitute for intellectual curiosity. For every old blackboard there are now hundreds of new electronic computers.

The prospect of domination of the nation’s scholars by Federal employment, project allocations, and the power of money is ever present and is gravely to be regarded.

Yet, in holding scientific research and discovery in respect, as we should, we must also be alert to the equal and opposite danger that public policy could itself become the captive of a scientific-technological elite.”

Voting Rights Doublespeak

The so-called insurrection that took place on January 6, 2021 (J6) has obsessed Democrats seeking to ram through a “voting rights” bill that they hope will advantage them in future elections. Oh, and to legitimize proposed new powers for agencies in the fight against “domestic terror”, and to somehow disqualify Donald Trump from holding the presidency again. We can thank a couple of moderate Democrats for shutting down the election bill, at least for the time being, by refusing to eliminate the filibuster.

The Real Threat to Voting Rights

If your real aim is to undermine ballot security and make it easier to cheat, you’d have to work hard to beat the election bill pushed by the Biden Administration: the Freedom To Vote Act (FVA). In their fashion, however, the Left prefers to stake-out phony rhetorical high-ground, replete with spurious charges against the opposition alleging racism and subversive, anti-democratic intent. Joe Biden demonstrated this vividly during his ill-advised speech in Georgia last week.

Here is a fairly thorough summary of the FVA, including an earlier version passed by the House last March. The overarching thrust of the bill is to substitute federal for state authority over the election process. States would not be permitted to demand that voters produce photo IDs. The bill would also require automatic voter registration at the department of motor vehicles and other government agencies, on-line registration, same-day registration, more days of early voting, excuse-free, notary-free, and witness-free absentee ballots, and extended counting of late-arriving ballots.

Democrats in the House of Representatives have now used a NASA funding bill as a shell for all these federally-prescribed protocols. Reportedly, this bill would legalize ballot harvesting nationwide, but that does not appear to be the case. Nevertheless, it includes all of the other provisions cited above, and many others.

While Congress certainly has the power to regulate elections, states were given the primary authority for conducting elections under the Constitution:

“The Times, Places and Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations, except as to the Places of chusing Senators.”

The Voting Rights Act of 1965 helped secure minority voting rights that plainly exist under the Constitution, and it prescribed federal review of certain changes in state voting procedures (some aspects of which were struck down by the Supreme Court). However, never before has such sweeping federal authority been proposed as to the range of mechanics involved in casting and counting ballots. Ballot security would be compromised by several provisions of the legislation.

While voter registration should be relatively painless, it should not be so painless that non-citizens find it easy to register. That is likely to be the case under automatic voter registration. Surely many non-citizens have much to recommend them, but they have not yet demonstrated their commitment to the nation through earned citizenship. The right to vote is a benefit of citizenship; it serves as an inducement to learn about our system of government through the naturalization process. These individuals might not be interested in going to the trouble, however, or they might be loyal to a foreign power. Do we really want such individuals to have a vote? And to the extent that their interest is focused on public benefits, they surely do not have an equal claim to natural-born but similarly-situated Americans.

Voter ID is a safeguard against voter fraud, and a huge majority of Americans support it, including majorities of minorities. The very idea that a photo ID requirement would “suppress” the legitimate votes of minorities is based on the presumption that those voters might have difficulty obtaining identification such as a drivers license or other government ID. Oh really? We can safely file that contention under “the bigotry of low expectations”.

Extensive use of absentee ballots was intended to facilitate voting during pandemic restrictions that were expected to reduce the safety and efficiency of polling places. However, most developed countries ban “mail-in voting”, regarding it as a prescription for voter fraud. That threat seems all too real given the lax standards proposed in the FVA.

The Threat to Political Opposition

The House investigative committee looking into the January 6th melee may recommend new intelligence powers for the federal government. Those powers aren’t needed to investigate the Capitol riot: the FBI has been in possession of teams of video evidence, and it has broad powers under the PATRIOT Act and other measures. Here’s Patrick Eddington from the link above:

“… the FBI already has unbelievably sweeping authority to surveil individual Americans or domestic groups without ever having to go before a judge to get a warrant.

Under an investigative category known as an assessment, FBI agents can search commercial and government databases (including databases containing classified information), run confidential informants, and conduct physical surveillance, all without a court order.”

The simple truth is that certain congressional Democrats and the Biden Administration are attempting to use the Capitol riot as an excuse to turn federal law enforcement against their political enemies. The claim by Biden, the guy who bragged of being mentored by Klansman Robert Byrd, and the same man who praised George Wallace on several occasions, is that his opponents are “domestic terrorists” and/or “white supremacists”. We’ve seen quite enough of this chicanery already. Having suffered through a lengthy “Russian collision” charade, a willingness to completely ignore massive riots and property destruction by BLM and Antifa activists in 2020, and an orchestrated attempt to treat concerned parents of schoolchildren as “domestic terrorists”, we’re expected to believe that these stooges need more power?

The J6 Fiasco

And that brings us back to the Capitol riot. It was, as Glenn Reynolds has said, a clownshow and a mess. But speaking of insurrection, let’s hope the FBI is keeping its eye on violent leftists as well, who perpetrated some unquestionably treasonous escapades in the not very distant past. From Legal Insurrection:

“…leftist rioters … attempted to stop the peaceful transition of power during President Trump’s inauguration. … did anti-Trump leftists riot, attack and injure police, set cars and buildings on fire… …

… the multi-day May, 2020 assault on the White House that left at least 60 Secret Service agents wounded and forced President Trump to be whisked away to a bunker for his personal safety.”

Even more dangerous leftist attacks on the Capitol building have been perpetrated, such as bombings by the Weather Underground in 1971 and the Armed Resistance in 1983.

Many people were hurt in the J6 riot through no real fault of their own, including Ashli Babbitt, who was shot and killed by a Capitol police officer shortly after she attempted to stop attackers from smashing windows. Nevertheless, those who breached the Capitol building were mostly a bunch of hapless goofballs encouraged to run amuck by certain instigators. Among those were the Oathkeepers, a gang who marched around in stack formation wearing gear that looked vaguely militaristic. They brought no weapons to the Capitol (though they had some stashed in the VA suburbs). Apparently, one of them did assist a crowd in barging through a door to the Capitol. Their activities on J6 have been described by one pundit as LARP — live action role playing. Nevertheless, there was much talk among them of interfering with the transfer of power to “the usurper”, as they called Joe Biden. And now, eleven of them have been charged with insurrection and sedition. Members of the Proud Boys were also at the Capitol, some of whom fought with police.

But what really happened to make things go off the rails on January 6th? This article by Joseph M. Hanneman offers an excellent discussion of the events of that afternoon, and the subsequent investigation. He notes the mysterious absence of a number of individuals involved in the breach of the Capitol and grounds from the FBI’s “Seeking Information” list of over 1,500 photos. That includes one Ray Epps, whose incitement was otherwise fairly well-documented. Some suspect certain parties with no interest in seeing Donald Trump remain in office actually encouraged the rioters, up to and including the FBI. Would that surprise anyone after the Whitmer kidnapping operation or the Russian collusion hoax?

The vast majority of the crowd on J6 came to the Capitol grounds to conduct a peaceful protest in the vain hope for congressional action to put a hold on the counting of electors pending state election audits, investigations, and court challenges. Many of those arrested were denied due process, and were held for months with no charges filed.

As for the “threat to the nation” posed by the crowd on J6, I found this Marco Rubio quote to be apropos:

“I don’t care how many candlelight vigils and musical performances you have from the cast of Hamilton, you’re not going to convince most normal and sane people that our government last year was almost overthrown by a guy wearing a Viking hat and speedos.”

Conclusion

Democrats still hope to vote to eliminate the Senate filibuster and then pass the FVA. That is a pipe dream at this point, but they would come to regret eliminating the filibuster in due course. They have used it themselves to defeat legislation hundreds of times in the recent past. The filibuster has its shortcomings, particularly its inability to restrain executive power. Nevertheless, it has never been more critical as protection against a tyrannical (and slim) majority in Congress.

The Freedom To Vote Act is doomed to failure. Still, no one should forget the mendacious rhetoric employed by Joe Biden and the leftist Democrat leadership in Congress on the issue of election integrity. Nor should anyone forget their dishonorable, anti-democratic intent to devalue legitimate voting rights.

Warming Bias and Hot-Town Thermometers

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

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

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

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

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

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

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

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

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

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

 

The Bad News Industrial Complex

Matt Ridley had an interesting piece on his blog last month entitled “Bad News Is Sudden, Good News Is Gradual“. It’s about the timing of news, as stated, and it’s about our bias toward bad news more generally. There is no question that bad news tends to be more dramatic than good news. But with steadily increasingly lifespans, growing prosperity, and world poverty at an all-time low, surely good news must come as much or more frequently than bad. But good news can be inconvenient to certain narratives. It is therefore often ignored, and some other purported disaster is found as a substitute:

“Poverty and hunger are the business Oxfam is in, but has it shouted the global poverty statistics from the rooftops? Hardly. It has switched its focus to inequality. When The Lancet published a study in 2010 showing global maternal mortality falling, advocates for women’s health tried to pressure it into delaying publication ‘fearing that good news would detract from the urgency of their cause’, The New York Times reported. The announcement by Nasa in 2016 that plant life is covering more and more of the planet as a result of carbon dioxide emissions was handled like radioactivity by most environmental reporters.“

Tales of bad outcomes can be alluring, especially if they haven’t happened yet. In fact, bad things might even happen gradually, but dark visions of a world beyond the horizon impart a spooky sense of immediacy, and indeed, urgency. Ridley notes the tendency of people to regard pessimists as “wise”, while optimists are viewed as Pollyannas. And he recognizes that risk aversion plays an important role in this psychology. That brings me to the point I found most interesting in Ridley’s piece: the many vested interests in disasters, and disasters foretold.

Risk management is big business in an affluent society. There is a lot to lose, and a squeamish populace is easily cowed by good scare stories. The risk management and disaster-prevention narrative can be wrapped around any number of unlikely or exaggerated threats, serving the interests of the administrative state and private rent-seekers. One particular tool that has been most useful to this alliance is the precautionary principle. It is invoked to discourage or regulate activities presumed to pose risks to the public or to the environment. But there are three dimensions to the application of the precautionary principle: it provides a rationale for public funding of research into the risk-du-jour, for funding projects designed to mitigate its consequences, and for subsidizing development of alternative technologies that might help avoid or reduce the severity of the risk, often at great expense. The exaggeration of risk serves to legitimize these high costs. Of course, the entire enterprise would be impossible without the machinery of the state, in all its venality. Where money flows, graft is sure to follow.

Well-publicized disaster scenarios are helpful to statists in other ways. Risk, its causes, and its consequences are not distributed evenly across regions and populations. A risk thought to be anthropomorphic in nature implies that wealthier and more productive communities and nations must shoulder the bulk of the global costs of mitigation. Thus, the risk-management ethic requires redistribution. Furthermore, wealthier regions are better situated to insulate themselves locally against many risks. Impoverished areas, on the other hand, must be assisted. Finally, an incredible irony of our preoccupation with disaster scenarios is the simultaneous effort to subsidize those deemed most vulnerable even while executing other policies that harm them.

Media organizations and their newspeople obviously benefit greatly from the subtle sensationalism of creeping disaster. As Ridley noted, the gradualism of progress is no match for a scare story on the nightly news. There is real money at stake here, but the media is driven not only by economic incentives. In fact, the dominant leftist ideology in media organizations means that they are more than happy to spread alarm as part of a crusade for state solutions to presumed risks. There are even well-meaning users of social media who jump at the chance to signal their virtue by reposting memes and reports that are couched not merely in terms of risks, but as dire future realities.

Mitigating social risks is a legitimate function of government. Unfortunately, identifying and exaggerating risks, and suppressing contradictory evidence, is in the personal interest of politicians, bureaucrats, crony capitalists, and many members of the media. Everything seems to demand government intervention. Carbon concentration, global warming and sea level changes are glaring examples of exaggerated risks. As Ridley says,

“The supreme case of unfalsifiable pessimism is climate change. It has the advantage of decades of doom until the jury returns. People who think the science suggests it will not be as bad as all that, or that humanity is likely to mitigate or adapt to it in time, get less airtime and a lot more criticism than people who go beyond the science to exaggerate the potential risks. That lukewarmers have been proved right so far cuts no ice.”

Other examples include the “beepocalypse“, genetic modification, drug use, school shootings, and certain risks to national security. Ridley offers the consequences of Brexit as well. There, I’ve listed enough sacred cows to irritate just about everyone.

In many cases, the real crises have more to do with government activism than the original issue with which they were meant to reckon. Which brings me to a discomfiting vision of my own: having allowed the administrative state to metastasize across almost every social organ and every aspect of our lives, a huge risk to our future well-being is continuing erosion of personal and economic liberties and our ability to prosper as a society. Here’s Ridley’s close:

“Activists sometimes justify the focus on the worst-case scenario as a means of raising consciousness. But while the public may be susceptible to bad news they are not stupid, and boys who cry ‘wolf!’ are eventually ignored. As the journalist John Horgan recently argued in Scientific American: ‘These days, despair is a bigger problem than optimism.'”

Sea Level Measurement and Perspective

26 Monday Mar 2018

The measurement of sea level change is much more complicated than most people realize. In fact, the reported changes that alarm so many are minuscule relative to the uncertainties caused by these measurement difficulties. First, consider the easy part: If you drive a stake into the ground at the shore at high tide one day, your task of measuring sea level change will be complicated by the changing day-to-day tides. Those changes will force you to calculate average readings off of your stake over complete lunar cycles (and even that isn’t quite right, since the gravitational pull of the sun matters as well, and the moon’s distance from earth fluctuates). Or, you can make comparisons only between readings one lunar cycle apart.

Once the local reference point is established at the shore and the tides are controlled for, there are two kinds of changes that cause the sea to rise or fall relative to the “zero” point on your stake. The sea water can rise or fall, of course, but the land itself might do so as well! Settling or upwelling at the land surface can be caused by a variety of geological phenomena. “Vertical land motion”, up or down, occurs almost everywhere. That means sea level is a relative concept. In addition, over time the placement of on-shore sea-level gauges often change with harbor and ship channel alterations, and even accidents. These all require adjustments in order to make valid comparisons across time. That’s to say nothing of variations in air pressure and water currents, which certainly affect on-shore readings. Today, sea levels are also measured by satellite, but that doesn’t make sea level measurement simpler by any means, as you’ll see below.

Kip Hansen discusses the vagaries of sea level measurement in an excellent post. If it isn’t already obvious, changes in readings from a single tide level gauge do not show the rate at which the absolute sea level is changing over time. It shows only the local net effect of the absolute sea level change and the land movement. But Hansen emphasizes an implication about which few are aware: a comparison of relative sea level changes in two different locales shows only the difference in “vertical land motion” between the two sites (at least as a first approximation).

Hansen notes a major discrepancy between the absolute sea level changes reported by NOAA (1.7 mm per year) and NASA (3.0 mm per year). These figures are estimated by satellite readings, which have extremely poor resolution (measured in cm, not mm) compared to tidal gauges. This quote from Hansen in the comments section is revealing (emphasis added):

“Satellite Altimetry — when reporting sea level rise — is not a measurement, but a complex calculation with a dozen or so ‘corrections’ and ‘adjustments’ for confounding factors, all of which are of greater magnitude than the change in sea surface height being sought. Many of these confounders are orders of magnitude greater. Some additions, such the famed GIA adjustment, are acknowledged not to appear in the physical sea surface height at all, but are added on the basis that ‘the sea would have risen the 0.3 mm/yr if the ocean basins hadn’t expanded. There is no scientific justification for the difference. In this essay, I point out that NOAA has stuck to its scientitic guns and not gone along with the NASA figure.“

There are statements on NOAA’s web site that seem to endorse the NASA estimate, but Hansen discounts those references. He advises that there is a big difference between the NOAA science community and its marketing staff, which undoubtedly dominates the content viewed by the public on the site.

There are many other factors that play havoc with sea level estimates, some of which are intractable. One issue, which comes up in the comments to Hansen’s article, has to do with sedimentation and its displacement of sea water. While its effect spreads out across the entire ocean, Hansen stops short of calling it a contributor to absolute sea level rise, though that would be the implication in terms of measurement.

Alarm over rising sea levels is based partly on the focus of local media on relative sea level changes. That may well be an important local issue, whether the land is settling or the absolute sea level is rising (though the two may have different local policy implications). But local concerns about relative sea level are often translated into global concerns that confuse relative with absolute sea levels. This makes excellent fodder for the propaganda of the leftist climate change movement. That propaganda is so effective that it sometimes feeds back to foment local concern, even in areas experiencing reductions in relative sea level! These concerns fly in the face of local experience as well as the absolute rates of change estimated by NOAA.

I’ll close with the following comment taken from an earlier post on SacredCowChips:

“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…. But even those fluctuations look minor by comparison to the increases in sea levels that occurred over 8,000 years ago.“

Slam the Damn Brakes on the Regulatory Potentate

The stock market’s recent gains have at least three plausible explanations: corporate earnings growth, the prospect of tax reform, and deregulation. Tax reform and deregulation are stated priorities of the Trump Administration and have the potential to lift the economy and generate additional earnings. Investors obviously like that prospect, though regulation itself is a tool used subversively by crony capitalists to stifle competition in their markets. Conceivably, some of the large firms that dominate major stock indices could suffer from deregulation. And I have to wonder whether the economic threat of Trumpian trade protectionism is not taken seriously by the equity markets. Let’s hope they’re right.

It’s no mystery that high taxes and tax complexity can inhibit economic growth. Let’s face it: when it comes to productive effort, we can all think of better things to do than tax planning, crony capitalist or not. The same is true of regulation: the massive diversion of resources into non-productive compliance activities stifles innovation, growth, and even the stability of the status quo. Regulation creates obstacles to activities like new construction and the diffusion of telecommunications services. And it discourages the creation of new products and services like potentially life-saving drugs and slows their introduction to market. The sheer number of federal regulations is so spectacular that one wonders how anything productive ever gets done! Patrick McLaughlin of The Mercatus Center and several coauthors tell of “The Impossibility of Comprehending, or Even Reading, All Federal Regulations“.

Regulation is more than a mere economic burden. It is the product of an administrative apparatus that is not subject to the checks and balances that are at the very heart of our system of constitutional government. That is a threat to basic liberties. Barry Brownstein offers an instructive case study of “The Tyranny of Administrative Power” involving violations of property rights in New Hampshire. The case involves the administrative machinations surrounding an installation of high-power lines.

Governmental efforts to spur innovation ordinarily take the form of spending on research, subsidies for certain technologies or favored industries (e.g., alternative energy), and large government programs dedicated to the achievement of various technological goals (e.g., NASA, DARPA). Together with regulatory rules that influence the allocation of resources, these governmental efforts are called industrial policy. An unfortunate recent example is Trump’s decision to retain the renewable fuel standard (RFS), but on the whole, industrial policy does not seem central to Trump’s effort to stimulate innovation.

It’s clear that a deregulatory effort is well underway: the so-called “deconstruction of the administrative state” hailed by Steve Bannon not long after Trump took office. First came Trump’s 2-for 1 executive order (also see here) requiring the elimination (or modification) of two rules for every new rule. In the Wall Street Journal, Greg Ip writes about changes at the FDA and the FCC that could dramatically alter the pace of innovation in the pharmaceutical and telecom industries. (If the link is gated, you access the article on the WSJ’s Facebook page.) Speedier and less burdensome reviews of new drugs will greatly benefit consumers. An end to net neutrality rules will support greater investment in broadband infrastructure and access to innovative services. There is a new emphasis at the FCC on enabling innovative solutions to communications problems, such as Google’s effort to provide cell phone service in Puerto Rico by flying balloons over the island. The Trump Administration is also reining-in an aggressive EPA, the source of many questionable rules that weaken property rights and inhibit growth. (Again, the RFS is a disappointing exception.) Health care reform could offer much needed relief from overzealous insurance regulation and high compliance costs for physicians and other providers.

But deconstructing the administrative state is hard. Regulations just seem to metastasize, so deregulatory gains are offset by continued rule-making. This is partly from new legislation, but it is also a consequence of the incentives facing self-interested regulators. With that in mind, it’s impressive that regulation has not grown, on balance, thus far into Trump’s first year in office. According to Patrick McLaughlin, zero regulatory growth has been unusual going back at least to the Carter Administration. In quoting McLaughlin, The Weekly Standard says that Trump might well earn the mantle of “King of Deregulation“, but he has a long way to go. Brookings has this interactive tool to keep track of his deregulatory progress. One item on the Brookings list is the President’s intention to withdraw from the Paris Climate Accord. That represents a big save in terms of avoiding future regulatory burdens.

I can’t help but be wary of other avenues through which the Trump Administration might regulate activity and undermine economic growth. Chief among these is Trump’s negative attitude toward foreign trade. Government interference with our freedom to freely engage in transactions with the rest of the world is costly in terms of both foreign and domestic prices. With something of a history as a crony capitalist himself, Trump is not immune to pressure from private economic interests, as illustrated by his recent cow-tow to the ethanol lobby. Nevertheless, I’m mostly encouraged by the administration’s deregulatory efforts, and I hope they continue. The equity market apparently expects that to be the case.

Manipulating Temperatures, People & Policy

The heavily-manipulated global surface temperatures quoted by NOAA and NASA point to another “hottest month on record” in July, but the satellite temperature measurements do not agree. Nor do several other widely-followed global temperature series maintained elsewhere, such as the UK Meteorological Office (UK Met Office). I wrote about the manipulation of surface temperatures by NOAA and NASA in January in “Record Hot Baloney“, and in “Fitting Data To Models At NOAA” in June:

“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 last link provides detail on the nature of the manipulations. Perhaps surprisingly, rather large downward adjustments have been made to historical temperature data, reinforcing any upward trend in the late 20th century and hiding the current 18-year pause in that trend. Suffice it to say that the “adjustments” made by these agencies are at fairly detailed levels; some of the before-and-after comparisons shown by gifs at this link are rather astonishing. Some climate researchers have started to refer to the temperature series as “reconstructions” instead of “data”, out of respect for the legitimacy of actual data.

In the meantime, the “warmist” propaganda keeps flowing from NOAA and NASA, and it is hungrily swallowed and then regurgitated by media alarmists. The media love a good scare story. They are so complicit in reinforcing the warmist narrative they will ignore the revelation of a faulty temperature sensor at National Airport in Washington, D.C. (another hat tip to John Crawford). It has been recording temperatures averaging 1.7 degrees Fahrenheit too warm for the past 19 months. Now that the sensor has been changed, NOAA states that it will not make any adjustments to the past 19 months of recorded temperatures from the National weather station, despite the fact that they have routinely made many other changes, often without any real explanation.

Here is a recent opinion from Duke University Professor Robert Brown on the divergence of satellite and NASA/NOAA surface temperatures and the adjustments to the latter:

“The two data sets should not be diverging, period, unless everything we understand about atmospheric thermal dynamics is wrong. That is, I will add my “opinion” to Werner’s and point out that it is based on simple atmospheric physics taught in any relevant textbook. …

This does not mean that they cannot and are not systematically differing; it just means that the growing difference is strong evidence of bias in the computation of the surface record.“

Every new report issued by NOAA/NASA on record warm temperatures should be severely discounted. They are toiling in the service of a policy agenda; it will cost you dearly, and it will severely punish the less fortunate here and especially in less developed parts of the world; and it will reward the statist elite, bureaucrats and Green crony capitalists. Ronald Bailey in Reason recently weighed in on the consequences of this “apocalyptic anti-progress ideology“. Or read the wise words of Matt Ridley on “The recurrent problem of green scares that don’t live up to the hype“. Hey greens, relax! And don’t waste our resources and our well being on precautions against exaggerated risks.

Will ET Be a Socialist?

If we are ever visited or contacted by agents from an extraterrestrial civilization, what kind of society will they come from? The issue is given scant attention, if any, in discussions of extraterrestrial life, at least according to this interesting piece in The Freeman by B.K. Marcus. The popular view, and that of many scientists, seems to be that the alien society will be dominated by an authoritarian central government. Must that be the case? Marcus notes the negative views taken by such scientific authorities as Neil deGrasse Tyson toward laissez faire capitalism, and even Carl Sagan “… could only imagine science funded by government.” Of course, Tyson and Sagan cannot be regarded as authorities on economic affairs. However, I admit that I have fallen into the same trap regarding extraterrestrial visitors: that they will come from a socialist society with strong central command. On reflection, like Marcus, I do not think this view is justified.

One explanation for the default view that extraterrestrial visitors will be socialists is that people uncritically accept the notion that an advanced society is a planned society.  This runs counter to mankind’s experience over the past few centuries: individual freedom, unfettered trade, capitalism and a spontaneous social order have created wealth and advancement beyond the wildest dreams of earlier monarchs. Anyone with a passing familiarity with data on world economic growth, or with F.A. Hayek, should know this, but it Is often overlooked. Central planners cannot know the infinitely detailed and dynamic information on technologies, resource availability, costs and preferences needed to plan a society with anything close to the success of one arranged through the voluntary cooperation of individual actors.

Many of us have a strong memory of government domination of space exploration, so we tend to think of such efforts as the natural province of government. Private contractors were heavily involved in those efforts, but the funding and high-level management of space missions (NASA in the U.S.) was dominated by government. Today, private space exploration is a growth industry, and it is likely that some of the greatest innovations and future space endeavors will originate in the private sector.

Another explanation for the popular view is the daunting social challenges that would be faced by crews in interstellar travel (IST). Given a relatively short life span, a colonizing mission would have to involve families and perhaps take multiple generations to reach its destination. There is a view that the mini-society on such a ship would require a command and control structure. Perhaps, but private property rights and a certain level of democratization would be advantageous. In any case, that carries no implication about the society on the home planet nor the eventual structure of a colony.

A better rationale for the default view of socialist ETs involves a public goods argument. The earth and mankind face infrequent but potentially catastrophic hazards, such as rogue asteroids and regions of strong radiation as the sun orbits the center of the Milky Way galaxy. These risks are shared, which implies that technological efforts to avert such hazards, or to perpetuate mankind by colonizing other worlds, are pure public goods. That means government has a classic role in providing for such efforts, as long as the expected benefits outweigh the costs. The standard production tradeoff discussed in introductory economics classes is “guns versus butter”, or national defense (a pure public good) versus private consumption. IST by an alien civilization could well require such a massive diversion of resources to the public sector that only an economically dominant central government could manage it. Or so it might seem.

As already noted, private entrepreneurs have debunked the presumed necessity that government must dominate space exploration. In fact, Elon Musk and his company SpaceX hope to colonize Mars. His motives sound altruistic, and in some sense the project sounds like the private provision of a public good. Here is an interpretation by Tim Urban quoted at the link (where I have inserted a substitute for the small time-scale analog used by the author):

“Now—if you owned a hard drive with an extraordinarily important Excel doc on it, and you knew that the hard drive pretty reliably tended to crash [from time to time] … what’s the very obvious thing you’d do?
You’d copy the document onto a second hard drive.
That’s why Elon Musk wants to put a million people on Mars.”

Musk has other incentives, however. The technology needed to colonize Mars will also pay handsome dividends in space mining applications. Moreover, if they are successful, there will come a time when Mars is a destination commanding a fare. Granted, this is not IST, but as technology advances through inter-planetary travel and colonization, there is a strong likelihood that future Elon Musks will be involved in the first steps outside of our solar system.

While SpaceX has raised its capital from private sources, it receives significant revenue from government contracts, so there is a level of dependence on public space initiatives. However, the argument made by Marcus at the first link above, that IST by ETs is less likely (or impossible) if they live under a socialist regime, is not based primarily on recent experience with private entrepreneurial efforts like Musk’s. Instead, it has to do with the inability of socialist regimes to generate wealth, especially the massive wealth necessary to accomplish IST.

Discussions of ETs (or the lack thereof) often center around a question known as the  Fermi Paradox, after the physicist Enrico Fermi. He basically asked: if the billions and billions of star systems, even in our own galaxy, are likely to harbor a respectable number of advanced civilizations, where are they? Why haven’t we heard from them? My friend John Crawford objects that this is no paradox at all, given the vastness of space and the difficulty and likely expense of IST. There may be advanced civilizations in the cosmos that simply have not been able to tackle the problem, at least beyond their own stellar neighborhood. No doubt about it, IST is hard!

I have argued to Crawford that there should be civilizations covering a wide range of development at any point in time. In only the past hundred years, humans have increased the speed at which they travel from less than 50 miles per hour (mph) to at least 9,600 mph. The speed of light is approximately 270,000 times faster that that! At our current top speed, it would take almost 50% longer to reach our nearest neighboring star, Alpha Centauri, than the entire span of human existence to-date. With that kind of limitation, there is no paradox at all! But I would not be surprised if, over the next 1,000 years, advances in propulsion technology bring our top speed to within one-tenth of the speed of light, and perhaps much more, making IST a more reasonable proposition, at least in our “neighborhood”. There may be civilizations that have already done so.

Answers to the Fermi Paradox often involve a concept called the Great Filter. This excellent HuffPo article by Tim Urban on the Fermi Paradox provides a good survey of theories on the Great Filter. The idea is that there are significant factors that prevent civilizations from advancing beyond certain points. Some of these are of natural origin, such as asteroids and radiation exposure. Others might be self-inflicted, such as a thermonuclear catastrophe or some other kind of technology gone bad. Some have suggested that the Large Hadron Collider in Switzerland could be a major hazard to our existence, though physicists insist otherwise. Another example is the singularity, when artificial intelligence overtakes human intelligence, creating a possibility that evil machines will do us in. The point of these examples is that some sudden or gradual development could prevent a civilization from surviving indefinitely. These kinds of filters provide an explanation for the Fermi Paradox.

More broadly, there could be less cataclysmic impediments to development that prevent a society from ever reaching an advanced stage. These would also qualify as filters of a sort. Perhaps the smart ETs lack, or failed to evolve, certain physical characteristics that are crucial for advancement or IST. Or their home planet might be light on certain kinds of resources. Or perhaps an inferior form of social organization has limited development, with inadequate wealth creation and technologies to transcend the physical limitations imposed by their world. On a smaller than planetary scale, we have witnessed such an impediment in action many times over: socialism. The inefficiencies of central planning place limits on economic growth, and while high authorities might dictate a massive dedication of resources toward science, technology and capital-intensive space initiatives, the shift away from personal consumption would come at a greater and greater cost. The end game may involve a collapse of production and a primitive existence. So the effort may be unsustainable and could lead to social upheaval; a more enlightened regime would attempt to move the society toward a more benign allocation of resources. Whether they can ever accomplish IST is at least contingent on their ability to create wealth.

Socialism is a filter on the advancement of societies. ETs capable of interstellar travel could not be spawned by a society dominated by socialism and central planning. While government might play a significant role in a successful ET civilization, one capable of IST, only a heavy reliance on free-market capitalism can improve the odds of advancing beyond a certain primitive state. Capitalism is a relatively easy ticket to the wealth required for an advanced and durable civilization, and conceivably to the reaches of the firmament.

Unfortunately, there is absolutely no guarantee that capitalistic ETs will be friendly  toward competing species, or that they will respect our property rights. They might be big, smart cats and find us mouse-like and quite tasty. Their children might make us perform circuses, like fleas. In any case, if ETs get this far, it’s probably because they want our world and our resources. My friend Crawford says that they won’t get here in any case. He believes that the difficulty of IST will force them to focus on their own neighborhood. Maybe, but on long enough time scales, who knows?

I would add a caveat to conclusions about the strength of the filters discussed above. A capitalistic society might reach a point at which it could send artificially intelligent, self-replicating machines into space to harvest resources. Those machines might well survive beyond the end of the civilization that created them. Conceivably, those machines could act autonomously or they could take coordinated action. But we haven’t heard from them either!

For a little more reading, here is SETI‘s description of the Fermi Paradox, and here is a post from io9 on the Great Filter.

warmist_year_evah_scr

It’s easy to make big headlines that serve a policy agenda when you can control the process generating “scientific” data. Here’s the latest in an ongoing fraud perpetrated by NASA, NOAA and a few other organizations. The disinformation is happily scooped up and reported by the unsuspecting news media, in this case The Wall Street Journal. The headline says that 2014 was the warmest year on record back to 1980, but there are several important respects in which the report from NASA and NOAA is misleading.

The surface temperature records maintained by NASA and NOAA (and others) utilize the same source data (despite NASA’s claim that the two series are “independent”), but they are heavily adjusted by the respective agencies. We can all probably agree that more recent temperature measurements (the raw data) are more reliable due to the availability of better and more numerous instruments (particularly for ocean surface temperatures). However, combining recent measurements with older data in a way that assures comparability is difficult over more than a few decades. Weather stations come, go, and relocate, environmental conditions around stations change with urbanization and airport expansions, and new measurement techniques are introduced.

Constructing a consistent temperature series over 130+ years at the world or regional level is therefore subject to much controversy. Here is a page with links to several good posts of the problems inherent in these efforts. Data is “infilled” and sometimes deleted, and statistical techniques are often applied in an effort to achieve consistency over time. However, it is curious that the NASA and NOAA adjustments over time seem to pivot around the levels of the 1950s and 1960s, as if to suggest that the temperatures measured in those decades are the most reliable part of the series. Take a look at the “gifs”in this post, which show temperatures before and after adjustments. An apparent consequence of the NASA / NOAA statistical techniques, which may seem even more curious to the casual observer, is that new observations can influence the entire temperature series. That is, adding 2014 temperatures to the series may lead to fresh downward adjustments to 1936 temperatures, if it suits the agencies. By the way, 1936 was a very warm year, but according to these agencies, it’s been getting less warm.

Another fascinating aspect of the report on 2014 temperatures is the obvious attempt to propagandize. This Bob Tisdale post sheds light on three serious omissions in the report and the related effort to “spin” the findings for the press:

1)  The range of uncertainty cited by NOAA in background documents indicates that the small margin (0.04 deg C for NOAA, 0.02 deg C by NASA) by which the reported 2014 global temperature exceeds the previous high is within the confidence interval around the previous high. By their own standard, it was “more unlikely than likely”that the 2014 temperature was the warmest on record, but that is not what the agencies report in their “Highlights.”

2) The report states that “This is the first time since 1990 the high temperature record was broken in the absence of El Niño conditions at any time during the year in the central and eastern equatorial Pacific Ocean….” Yet there were El Nino conditions elsewhere in the Pacific in 2014.

3) “NOAA failed to discuss the actual causes of the elevated global sea surface temperatures in 2014, while making it appear that there was a general warming of the surfaces of the global oceans.”

Tisdale notes elsewhere that the tiny margins of “record warmth” reported by NASA and NOAA contribute to a growing disparity between reported “actual temperatures” and those projected by climate warming models. The “Warmist” community will view the NASA / NOAA findings favorably, as the new “record high” supports their narrative,” providing new fodder for the agenda to end the use of fossil fuels and to regulate activities deemed “unsustainable.” Unfortunately, the misleading reports are likely to seem credible to the general public, which is largely ignorant of the agencies’ rampant manipulation of temperature data.

CO2, Vegetation and Ocean Heat Sink Fiction

China CO2 Deal

A new paper reported here debunks an important feature of IPCC climate models: that the oceans absorb infrared radiation from greenhouse gases, thus heating the oceans and accounting for the “missing heat” predicted by climate models. No, they do not. The research, which appeared in the Proceedings of the National Academy of Sciences, identified several physical reasons that ocean warming from CO2 is all but impossible. From the link above:

“For all … of these physical reasons… ocean warming can only be related to solar activity and modulators of sunshine at the surface like clouds, and not increased far-IR radiation from increased greenhouse gases.

This is a death knell for conventional climate models, which falsely assume the opposite of the … physical reasons above, thus falsely claiming IR from greenhouse gases can heat the oceans (70% of Earth’s surface area) and where allegedly 90% of the ‘missing heat’ has gone.”

One of those physical reasons is related to whether water and water vapor act as “blackbodies,” which is assumed by climate models embodying AGW. They do not:

“The significance to the radiative ‘greenhouse effect’ is that the climate is less sensitive to both CO2 and water vapor since both are less ‘greenhouse-like’ emitters and absorbers of IR radiation as temperatures increase.”

So the oceans are not the massive AGW heat sinks that we hear about so often. And much of that “nasty” CO2 finds eager vegetative consumers: This article reports research suggesting that 90% of CO2 emissions are stimulating forest growth around the world:

“Even NASA’s own satellite data shows that the planet is steadily greening, by as much as 1.5 percent a year in northern latitudes. Yet in May last year, the world’s media mournfully reported that atmospheric CO2 had just passed the 400ppm mark for the first time in three to five million years, with NASA clamouring to paint the news in a calamitous light. …

Nova says ‘the northern Boreal forests are probably drawing down something like 2 – 5 gigatons of CO2 every year, and because the seasonal amplitude is getting larger each year, it suggests there is no sign of saturation. Those plants are not bored of extra CO2 yet. This fits with Craig Idso’s work on plant growth which demonstrates that the saturation point — where plants grow as fast as possible (and extra CO2 doesn’t help) is somewhere above 1000 and below 2000ppm. We have a long way to go.’”

I believe a greener world is preferable to a less green one. In fact, I believe a somewhat warmer world is preferable. That would bring many obvious benefits to mankind, not least of which is a reduction in weather-related misery and death. (No, severe weather is not an implication of a warner climate.) I therefore find it bizarre that so many have been successfully propagandized to believe that we should sacrifice vast amounts of resources to prevent AGW. It is not a danger of much significance. There are explanations for the propaganda, of course, but they will have to be the subject of another post.
