Vaccines: The good, the bad, and the ugly

Posted by Henry Bauer on 2017/05/21

Only in recent years have I begun to wonder whether there are reasons not to follow official recommendations about vaccination. In the 1930s, I had the then-usual vaccinations, including (in Austria, perhaps Europe) against smallpox. A few others in later years when I traveled quite a bit.

But the Andrew Wakefield affair *, and the introduction of Gardasil **, showed me that official sources had become as untrustworethy about vaccines as they have become about prescription drugs.

It seems that Big Pharma had just about run out of new diseases to invent against which to create drugs and had turned to snake-oil-marketing of vaccines. We are told, for example, that 1 in 3 people will experience shingles in their lifetime and should get vaccinated against it. Have one in three of your aged friends ever had shingles? Not among my family and friends. One of my buddies got himself vaccinated, and came down with shingles a couple of weeks later. His physician asserted that the attack would have been more severe if he hadn’t been vaccinated — no need for a control experiment, or any need to doubt official claims.

So it’s remarkable that the Swedish Government has resisted attempts to make vaccinations compulsory (“Sweden bans mandatory vaccinations over ‘serious health concerns’” by Baxter Dmitry, 12 May 2017).

That article includes extracts from an interview of Robert F. Kennedy, Jr., on the Tucker Carlson Show, which included such tidbits as the continued presence of thimerosal (organic mercury compound) in many vaccines including the seasonal flu vaccines that everyone is urged to get; and the huge increase in number of things against which vaccination is being recommended:

“I got three vaccines and I was fully compliant. I’m 63 years old. My children got 69 doses of 16 vaccines to be compliant. And a lot of these vaccines aren’t even for communicable diseases. Like Hepatitis B, which comes from unprotected sex, or using or sharing needles – why do we give that to a child on the first day of their life? And it was loaded with mercury.”

Superstitious belief in science

Posted by Henry Bauer on 2017/05/16

Most people have a very misled, unrealistic view of “science”. A very damaging consequence is that scientific claims are given automatic respect even when that is unwarranted — as it always is with new claims, say about global warming. Dramatic changes in how science is done, especially since mid-20th century, make it less trustworthy than earlier.

In 1987, historian John Burnham published How Superstition Won and Science Lost, arguing that modern science had not vanquished popular superstition by inculcating scientific, evidence-based thinking; rather, science had itself become on worldly matters the accepted authority whose pronouncements are believed without question, in other words superstitiously, by society at large.

Burnham argued through detailed analysis of how science is popularized, and especially how that has changed over the decades. Some 30 years later, Burnham’s insight is perhaps even more important. Over those years, certain changes in scientific activity have also become evident that support Burnham’s conclusion from different directions: science has grown so much, and has become so specialized and bureaucratic and dependent on outside patronage, that it has lost any ability to self-correct. As with religion in medieval times, official pronouncements about science are usually accepted without further ado, and minority voices of dissent are dismissed and denigrated.

A full discussion with source references, far too long for a blog post, is available here.

Climate-change orthodoxy: alternative facts, uncertainty equals certainty, projections are not predictions, and other absurdities of the “scientific consensus”

Posted by Henry Bauer on 2017/05/10

G. K. Chesterton once suggested that the best argument for accepting the Christian faith lies in the reasons offered by atheists and skeptics against doing so. That interesting slant sprang to mind as I was trying to summarize the reasons for not believing the “scientific consensus” that blames carbon dioxide for climate change.

Of course the very best reason for not believing that CO2 causes climate change are the data, as summarized in an earlier post

–>      Global temperatures have often been high while CO2 levels were low, and vice versa

–>     CO2 levels rise or fall after temperatures have risen or fallen

–>     Temperatures decreased between the 1940s and 1970s, and since about 1998 there has been a pause in warming, perhaps even cooling, while CO2 levels have risen steadily.

But disbelieving the official propaganda becomes much easier when one recognizes the sheer absurdities and illogicalities and self-contradictions committed unceasingly by defenders of the mainstream view.

1940s-1970s cooling
Mainstream official climate science is centered on models: computer programs that strive to simulate real-world phenomena. Any reasonably detailed description of such models soon reveals that there are far too many variables and interactions to make that feasible; and moreover that a host of assumptions are incorporated in all the models (1). In any case, the official models do not simulate the cooling trend of these three decades.
“Dr. James Hansen suspects the relatively sudden, massive output of aerosols from industries and power plants contributed to the global cooling trend from 1940-1970” (2).
But the models do not take aerosols into account; they are so flawed that they are unable to simulate a thirty-year period in which carbon emissions were increasing and temperatures decreasing. An obvious conclusion is that no forecast based on those models deserves to be given any credence.

One of the innumerable science-groupie web-sites expands on the aerosol speculation:
“40’s to 70’s cooling, CO2 rising?
This is a fascinating denialist argument. If CO2 is rising, as it was in the 40’s through the 70’s, why would there be cooling?
It’s important to understand that the climate has warmed and cooled naturally without human influence in the past. Natural cycle, or natural variability need to be understood if you wish to understand what modern climate forcing means. In other words modern or current forcing is caused by human industrial output to the atmosphere. This human-induced forcing is both positive (greenhouse gases) and negative (sulfates and aerosols).”

Fair enough; but the models fail to take account of natural cycles.

Rewriting history
The Soviet Union had an official encyclopedia that was revised as needed, for example by rewriting history to delete or insert people and events to correspond with a given day’s political correctness. Some climate-change enthusiasts also try to rewrite history: “There was no scientific consensus in the 1970s that the Earth was headed into an imminent ice age. Indeed, the possibility of anthropogenic warming dominated the peer-reviewed literature even then” (3). Compare that with a host of reproductions and citations of headlines from those cold times when media alarms were set off by what the “scientific consensus” indeed then was (4). And the cooling itself was, of course, real, as is universally acknowledged nowadays.

The media faithfully report what officialdom disseminates. Routinely, any “extreme” weather event is ascribed to climate change — anything worth featuring as “breaking news”, say tsunamis, hurricanes, bushfires in Australia and elsewhere. But the actual data reveal no increase in extreme events in recent decades: not Atlantic storms, nor Australian cyclones, nor US tornadoes, nor “global tropical cyclone accumulated energy”, nor extremely dry periods in the USA, in the last 150 years during which atmospheric carbon dioxide increased by 40% (pp. 46-51 in (1)). Nor have sea levels been rising in any unusual manner (Chapter 6 in (1)).

Defenders of climate-change dogma tie themselves in knots about whether carbon dioxide has already affected climate, whether its influence is to be seen in short-term changes or only over the long term. For instance, the attempt to explain 1940s-70s cooling presupposes that CO2 is only to be indicted for changes over much longer time-scales than mere decades. Perhaps the ultimate demonstration of wanting to have it both ways — only long-term, but also short-term — is illustrated by a pamphlet issued jointly by the Royal Society of London and the National Academy of Science of the USA (5, 6).

No warming since about 1998
Some official sources deny that there has been any cessation of warming in the new century or millennium. Others admit it indirectly by attempting to explain it away or dismiss it as irrelevant, for instance “slowdowns and accelerations in warming lasting a decade or more will continue to occur. However, long- term climate change over many decades will depend mainly on the total amount of CO2 and other greenhouse gases emitted as a result of human   activities” (p. 2 in (5)); “shorter-term variations are mostly due to natural causes, and do not contradict our fundamental understanding that the long-term warming trend is primarily due to human-induced changes in the atmospheric levels of CO2 and other greenhouse gases” (p. 11 in (5)).

Obfuscating and misdirecting
The Met Office, the UK’s National Meteorological Service, is very deceptive about the recent lack of warming:

“Should climate models have predicted the pause?
Media coverage … of the launch of the 5th Assessment Report of the IPCC has again said that global warming is ‘unequivocal’ and that the pause in warming over the past 15 years is too short to reflect long-term trends.

[No one disputes the reality of long-term global warming — the issue is whether natural forces are responsible as opposed to human-generated carbon dioxide]

… some commentators have criticised climate models for not predicting the pause. …
We should not confuse climate prediction with climate change projection. Climate prediction is about saying what the state of the climate will be in the next few years, and it depends absolutely on knowing what the state of the climate is today. And that requires a vast number of high quality observations, of the atmosphere and especially of the ocean.
On the other hand, climate change projections are concerned with the long view; the impact of the large and powerful influences on our climate, such as greenhouse gases.

[Implying sneakily and without warrant that natural forces are not “large and powerful”. That is quite wrong and it is misdirection, the technique used by magicians to divert attention from what is really going on. By far the most powerful force affecting climate is the energy coming from the sun.]

Projections capture the role of these overwhelming influences on climate and its variability, rather than predict the current state of the variability itself.
The IPCC model simulations are projections and not predictions; in other words the models do not start from the state of the climate system today or even 10 years ago. There is no mileage in a story about models being ‘flawed’ because they did not predict the pause; it’s merely a misunderstanding of the science and the difference between a prediction and a projection.
[Misdirection again. The IPCC models failed to project or predict the lack of warming since 1998, and also the cooling of three decades after 1940. The point is that the models are inadequate, so neither predictions nor projections should be believed.]

… the deep ocean is likely a key player in the current pause, effectively ‘hiding’ heat from the surface. Climate model projections simulate such pauses, a few every hundred years lasting a decade or more; and they replicate the influence of the modes of natural climate variability, like the Pacific Decadal Oscillation (PDO) that we think is at the centre of the current pause.
[Here is perhaps the worst instance of misleading. The “Climate model projections” that are claimed to “simulate such pauses, a few every hundred years lasting a decade or more” are not made with the models that project alarming human-caused global warming, they are ad hoc models that explore the possible effects of variables not taken into account in the overall climate models.]”

The projections — which the media (as well as people familiar with the English language) fail to distinguish from predictions — that indict carbon dioxide as cause of climate change are based on models that do not incorporate possible effects of deep-ocean “hidden heat” or such natural cycles as the Pacific Decadal Oscillation. Those and other such factors as aerosols are considered only in trying to explain why the climate models are wrong, which is the crux of the matter. The climate models are wrong.

Asserting that uncertainty equals certainty
The popular media disseminated faithfully and uncritically from the most recent official report that “Scientists are 95% certain that human are responsible for the ‘unprecedented’ warming experienced by the Earth over the last few decades

Leave aside that the warming cannot be known to be “unprecedented” — global temperatures have been much higher in the past, and historical data are not fine-grained enough to compare rates of warming over such short time-spans as mere decades or centuries.

There is no such thing as “95% certainty”.
Certainty means 100%; anything else is a probability, not a certainty.
A probability of 95% may seem very impressive — until it is translated into its corollary: 5% probability of being wrong; and 5% is 1 in 20. I wouldn’t bet on anything that’s really important to me if there’s 1 chance in 20 of losing the bet.
So too with the frequent mantra that 97% or 98% of scientists, or some other superficially impressive percentage, support the “consensus” that global warming is owing to carbon dioxide (7):

 

“Depending on exactly how you measure the expert consensus, it’s somewhere between 90% and 100% that agree humans are responsible for climate change, with most of our studies finding 97% consensus among publishing climate scientists.”

In other words, 3% (“on average”) of “publishing climate scientists” disagree. And the history of science teaches unequivocally that even a 100% scientific consensus has in the past been wrong, most notably on the most consequential matters, those that advanced science spectacularly in what are often called “scientific revolutions” (8).
Furthermore, “publishing climate scientists” biases the scales a great deal, because peer review ensures that dissenting evidence and claims do not easily get published. In any case, those percentages are based on surveys incorporating inevitable flaws (sampling bias as with peer review, for instance). The central question is, “How convinced are you that most recent and near future climate change is, or will be, the result of anthropogenic causes”? On that, the “consensus” was only between 33% and 39%, showing that “the science is NOT settled” (9; emphasis in original).

Science groupies — unquestioning accepters of “the consensus”
The media and countless individuals treat the climate-change consensus dogma as Gospel Truth, leading to such extraordinary proposals as that by Professor of Law, Philippe Sands, QC, that “False claims from climate sceptics that humans are not responsible for global warming and that sea level is not rising should be scotched by an international court ruling”.

I would love to see any court take up the issue, which would allow us to make defenders of the orthodox view attempt to explain away all the data which demonstrate that global warming and climate change are not driven primarily by carbon dioxide.

The central point

Official alarms and established scientific institutions rely not on empirical data, established facts about temperature and CO2, but on computer models that are demonstrably wrong.

Those of us who believe that science should be empirical, that it should follow the data and change theories accordingly, become speechless in the face of climate-change dogma defended in the manner described above. It would be screamingly funny, if only those who do it were not our own “experts” and official representatives (10). Even the Gods are helpless in the face of such determined ignoring of reality (11).

Climate-change facts: Temperature is not determined by carbon dioxide

Posted by Henry Bauer on 2017/05/02

The mainstream claims about carbon dioxide , global warming, and climate change, parroted by most media and accepted by most of the world’s governments, are rather straightforward: carbon dioxide released in the burning of “fossil fuels” (chiefly coal and oil) drives global warming because CO2 is a “greenhouse gas”, absorbing heat that would otherwise radiate harmlessly out into space. Since the mid-19th century, when the Industrial Revolution set off this promiscuous releasing of CO2, the Earth has been getting hotter at an unprecedented pace.

The trouble with these claims is that actual data demonstrate that global temperature is not determined by the amount of CO2 in the atmosphere.

For example, during the past 500 million years, CO2 levels have often been much higher than now, including times when global temperatures were lower (1):

“The gray bars at the top … correspond to the periods when the global climate was cool; the intervening white space corresponds to the warm modes … no correspondence between pCO2 and climate is evident …. Superficially, this observation would seem to imply that pCO2 does not exert dominant control on Earth’s climate …. A wealth of evidence, however, suggests that pCO2 exerts at least some control …. [but this Figure] … shows that the ‘null hypothesis’ that pCO2 and climate are unrelated cannot be rejected on the basis of this evidence alone.” [To clarify convoluted double negative: All the evidence cited in support of mainstream claims is insufficient to over-rule what the above Figure shows, that CO2 does not determine global temperatures (the “null hypothesis”).]

Again, with temperature levels in quantitative detail (2):

Towards the end of the Precambrian Era, CO2 levels (purple curve) were very much higher than now while temperatures (blue curve) were if anything lower. Over most of the more recent times, CO2 levels have been very much lower while temperatures most of the time were considerably higher.

Moreover, the historical range of temperature fluctuations makes a mockery of contemporary mainstream ambitions to prevent global temperatures rising by as much as 2°C; for most of Earth’s history, temperatures have been about 6°C higher than at present.

Cause precedes effect

The data just cited do not clearly demonstrate whether rising CO2 brings about subsequent rises in temperature — or vice versa. However, ice-core data back as far as 420,000 years do show which comes first: temperature changes are followed by CO2 changes (3):

On average, CO2 rises lag about 800 years behind temperature rises; and CO2 levels also decline slowly after temperatures have fallen.

Since the Industrial Revolution

Over the last 150 years, global temperatures have risen, and levels of CO2 have risen. This period is minuscule by comparison to the historical data summarized above. Crucially, what has happened in this recent sliver of time cannot be compared directly to the past because the historical data are not fine-grained enough to discern changes over such short periods of time. What is undisputed, however, is that CO2 and temperature have not increased in tandem in this recent era, just as over geological time-spans. From the 1940s until the 1970s, global temperatures were falling, and mainstream experts were telling the mass media that an Ice Age was threatening (4) — at the same time as CO2 levels were continuing their merry rise with fossil fuels being burnt at an ever-increasing rate (5):

1945 to 1977 cool period with soaring CO2 emissions. Global temperatures began to cool in the mid–1940’s at the point when CO2 emissions began to soar … . Global temperatures in the Northern Hemisphere dropped about 0.5°C (0.9° F)
from the mid-1940s until 1977 and temperatures globally
cooled about 0.2°C (0.4° F) …. Many of the world’s glaciers advanced during this time and recovered a good deal
of the ice lost during the 1915–1945 warm period”.

Furthermore (5):

Global cooling from 1999 to 2009. No global warming has occurred above the 1998 level. In 1998, the PDO [Pacific Decadal Oscillation] was in its warm mode. In 1999, the PDO flipped from its warm mode into its cool mode and satellite imagery confirms that the cool mode has become firmly entrenched since then and global cooling has deepened significantly in the past few years.”

In short:
–>       Global temperatures have often been high
while CO2 levels were low, and vice versa
–>        CO2 levels rise or fall after temperatures have risen or fallen
–>         CO2 levels have risen steadily but temperatures decreased
between the 1940s and 1970s, and since about 1998
there has been a pause in warming, perhaps even cooling

Quite clearly, CO2 is not the prime driver of global temperature. Data, facts, about temperature and CO2 demonstrate that something else has far outweighed the influence of CO2 levels in determining temperatures throughout Earth’s history, including since the Industrial Revolution. “Something else” can only be natural forces. And indeed there are a number of known natural forces that affect Earth’s temperature; and many of those forces vary cyclically over time. The amount of energy radiated to Earth by the Sun varies in correlation with the 11-year periodic cycle of sun-spots, which is fairly widely known; but there are many other cycles known only to specialists, say the 9-year Lunisolar Precession cycle; and these natural forces have periodically warmed and cooled the Earth in cycles of glaciation and warmth at intervals of roughly 100,000 – 120,000 years (the Milankovitch Cycles), with a number of other cycles superposed on those (6).

So the contemporary mainstream view, the so-called “scientific consensus”, is at odds with the evidence, the facts.

That will seem incredible to many people, who might well ask how that could be possible. How could “science” be so wrong?

In brief: because of facts about science that are not much known outside the ranks of historians and philosophers and sociologists of science (7): that the scientific consensus at any given time on any given matter has been wrong quite often over the years and centuries (8); and that science nowadays has become quite different from our traditional view of it (9).
