Science or Selective Ignorance?
In an editorial published in Science magazine on July 3, Marcia McNutt, Editor-in-Chief of the Science Journals, removed all doubt concerning the direction that this once prestigious journal is taking.
In “The beyond-two-degree inferno”, she wrote: “The time for debate has ended. Action is urgently needed.”
Then, she strongly supports the contrived effort of the European Union to keep “global warming” below 2°C above the preindustrial level – a number for which we have no rigorous measurement or logic.
She advocates the political position of the Administration in forcing reductions in carbon dioxide emission (CO2) by stating “The United States has pledged reductions of 26 to 28{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} below 2005 levels by 2025…” Of course, there is no such pledge by the American people and its representatives in Congress. The Administration’s pledge is arbitrary and authoritarian. Ms. McNutt concludes with a description of the nine circles of Hell found in Dante’s Inferno.
Ms. McNutt continues a trend established in the Science journals by Donald Kennedy (2000-2008), who declared while he is editor, Science would no longer accept articles contradicting the pronouncements of the Intergovernmental Panel on Climate Change (IPCC) on global warming, later termed climate change, regardless of the empirical data presented.
The IPCC reports featured glaring deficiencies such as the falsely named distinct human fingerprint, a hot-spot over the tropics, which no one can empirically find; Mr. Mann’s hockey-stick, based on sparse data, from which contradicting data was deleted; and global climate models, which greatly overestimate warming, as current measurements demonstrate. The logic behind this editorial policy can be described as selective ignorance. Please see links under Defending the Orthodoxy, including an excellent critique by Judith Curry.
16th Century Thinking: European scientific thinking of the 16th century was dominated by the re-discovery of the works of the Greeks. Their works in geometry and astronomy were very good, particularly considering the lack of precise instruments. Estimates of size of the earth and the moon, and the distance between them were quite accurate. However, they generally underestimated the size of the sun and its distance from the earth.
The concept of a heliocentric solar system was suggested by Aristarchus (died about 232 B.C.) and was accepted by some astronomers but eventually rejected, particularly by Ptolemy, a Roman, (about 150 A.D), whose system became the one widely accepted in the 16th century. During the 16th century, learning and written documents were extremely limited, and authority and consensus were dominate.
Copernicus disagreed with the Ptolemy concept of the solar system, but the work was not published until the year of his death in 1543. It was up to Galileo to earn the full wrath of the Greek scholars (often called Aristotelian scientists) that dominated science in the period. Galileo confronted the scientific models and assumptions of the era with observations from nature and experiments.
The most dramatic of these confrontations was proposing a heliocentric solar system, with an earth that orbited the sun annually, rotated daily, and titled on its axis. [Kepler proposed elliptical, not circular, orbits doing away with epicycles, and non-uniform speeds.] Using a telescope, Galileo identified spots on the sun, refuting the notion that it was immutable (unchanging). There are various versions of what occurred in the 17th century (until Newton) and the importance of various groups.
However, for the purposes of this discussion, one must note that Galileo was the first, influential astronomer of the Renaissance to propose that observations take precedence over authority and consensus of opinion as the objective standard in science. He incurred the full wrath of the scientific establishment of that time.
The Sun? Royal Astronomical Society published a study of a “new model of the Sun’s solar cycle is producing unprecedentedly accurate predictions of irregularities within the Sun’s” 10 to 12 year solar cycle. “The model draws on dynamo effects in two layers of the Sun, one close to the surface and one deep within its convection zone. Predictions from the model suggest that solar activity will fall by 60 per cent during the 2030s to conditions last seen during the ‘mini ice age’ that began in 1645.”
“It is 172 years since a scientist first spotted that the Sun’s activity varies over a cycle lasting around 10 to 12 years. But every cycle is a little different and none of the models of causes to date have fully explained fluctuations. Many solar physicists have put the cause of the solar cycle down to a dynamo caused by convecting fluid deep within the Sun. Now, Zharkova and her colleagues have found that adding a second dynamo, close to the surface, completes the picture with surprising accuracy.”
“We found magnetic wave components appearing in pairs, originating in two different layers in the Sun’s interior. They both have a frequency of approximately 11 years, although this frequency is slightly different, and they are offset in time. Over the cycle, the waves fluctuate between the northern and southern hemispheres of the Sun. Combining both waves together and comparing to real data for the current solar cycle, we found that our predictions showed an accuracy of 97{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117},” said Zharkova.
Zharkova and her colleagues derived their model using a technique called ‘principal component analysis’ of the magnetic field observations from the Wilcox Solar Observatory in California. They examined three solar cycles-worth of magnetic field activity, covering the period from 1976-2008. In addition, they compared their predictions to average sunspot numbers, another strong marker of solar activity. All the predictions and observations were closely matched.
Looking ahead to the next solar cycles, the model predicts that the pair of waves become increasingly offset during Cycle 25, which peaks in 2022. During Cycle 26, which covers the decade from 2030-2040, the two waves will become exactly out of synch and this will cause a significant reduction in solar activity.
“In cycle 26, the two waves exactly mirror each other – peaking at the same time but in opposite hemispheres of the Sun. Their interaction will be disruptive, or they will nearly cancel each other. We predict that this will lead to the properties of a ‘Maunder minimum’,” said Zharkova. “Effectively, when the waves are approximately in phase, they can show strong interaction, or resonance, and we have strong solar activity. When they are out of phase, we have solar minimums. When there is full phase separation, we have the conditions last seen during the Maunder minimum, 370 years ago.”
Since the period covered in the testing is only three solar cycles, 1976 to 2008, it is far too brief to draw any long-term conclusions. However, the accuracy in the testing is significant. Further, the cooling corresponds with predictions from some other solar scientists.
The short period of study understood, The Summary for Policymakers of Fifth Assessment Report (AR-5), Synthesis Report, of the IPCC also covers a relatively short period. Table SPM.3 presents “Contributions to observed surface temperature change over the period 1951-2010.” Yet, the IPCC expressed 95{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} certainty in its work.
The total of natural forcings presented by the IPCC in this table covers a temperature range of about minus 0.1 ºC to plus 0.1 ºC. If the new report of the Royal Astronomical Society bears out, and we experience a cooling greater than 0.1 ºC, the IPCC and the climate establishment has significant problems.
