Anthropogenic Global Warming (AGW); A Tangled Web Strangling Its Creators and Proponents

WUWT March 3, 2019

Guest opinion: Dr. Tim Ball

Two recent events triggered the idea for this article. On the surface, they appear unconnected, but that is an indirect result of the original goal and methods of global warming science. We learned from Australian Dr, Jennifer Marohasy of another manipulation of the temperature record in an article titled Data mangling: BoM’s Changes to Darwin’s Climate History are Not Logical.” The second involved the claim of final, conclusive evidence of Anthropogenic Global Warming ((AGW). The original article appeared in the journal Nature Climate Change. Because it is in this journal raises flags for me. The publishers of the journal Nature created the journal. That journal published as much as it could to promote the deceptive science used for the untested AGW hypothesis. However, they were limited by the rules and procedures required for academic research and publications. This isn’t a problem if the issue of global warming was purely about science, but it never was. It was a political use of science for a political agenda from the start. The original article came from a group led by Ben Santer, a person with a long history of involvement in the AGW deception.

Note on the Theory of the Greenhouse

[Page 319] By Professor R. W. Wood

THERE appears to be a widespread belief that the comparatively high temperature produced within a closed space covered with glass, and exposed to solar radiation, results from a transformation of wave-length, that is, that the heat waves from the sun, which are able to penetrate the glass, fall upon the walls of the enclosure and raise its temperature : the heat energy is re-emitted by the walls in the form of much longer waves, which are unable to penetrate the glass, the greenhouse acting as a radiation trap.

I have always felt some doubt as to whether this action played any very large part in the elevation of temperature. It appeared much more probable that the part played by the glass was the prevention of the escape of the warm air heated by the ground within the enclosure. If we open the doors of agreenhouse on a cold and windy day, the trapping of radiation appears to lose much of its efficacy. Asa matter of fact I am of the opinion that a greenhouse made of a glass transparent to waves of every possible length would show a temperature nearly, if not quite, as high as that observed in a glass house. The transparent screen allows the solar radiation to warm the ground, and the ground in turn THERE appears to be a widespread belief that the comparatively high temperature produced within aclosed space covered with glass, and exposed to solar radiation, results from a transformation of wave-length, that is, that the heat waves from the sun, which are able to penetrate the glass, fall upon the walls of the enclosure and raise its temperature: the heat energy is re-emitted by the walls in the form of much longer waves, which are unable to penetrate the glass, the greenhouse acting as aradiation trap.

Prof Murry Salby Lecture; “Atmospheric Carbon” 18th July 2016

Professor Murry Salby, author of many peer-reviewed papers, and the seminal book on climate “Physics of the Atmosphere and Climate”, is one of the planet’s best climate scientists, here he gives a scientific / technical talk on carbon in the atmosphere delivered at University College London on the 18th July, 2016. Salby outlines man’s true contribution to the observed increase in atmospheric CO2 concentrations.

All public policies, in France, Europe and throughout the world, find their origin and
inspiration in the battle against global warming. The initial credo is simple: temperatures
at the surface of the planet have been rising constantly for the past thirty years, and
human beings are to blame.

This is leading to all sorts of discussions, conferences and regulations, which are having an
enormous impact on our economy. Every area of activity is affected: transport, housing,
energy – to name just a few. Why do we need to save energy? It is quite simple: we have to
reduce human impact on the planet. This is the fundamental credo.

Abstract: The rise in global average temperature over the last century has halted since roughly the year 2000, despite the fact that the release of CO2 into the atmosphere is still increasing. It is suggested here that this interruption has been caused by the suspension of the near linear (+ 0.5° C/100 years or 0.05° C/10 years) temperature increase over the last two centuries, due to recovery from the Little Ice Age, by a superposed multi-decadal oscillation of a 0.2° C amplitude and a 50~60 year period, which reached its positive peak in about the year 2000—a halting similar to those that occurred around 1880 and 1940. Because both the near linear change and the multi-decadal oscillation are likely to be natural changes (the recovery from the Little Ice Age (LIA) and an oscillation related to the Pacific Decadal Oscillation (PDO), respectively), they must be carefully subtracted from temperature data before estimating the effects of CO2.

The Green New Deal: Scope, Scale, and Implications

The Green New Deal (GND) is a sweeping policy plan setting out ambitious objectives for energy and economic policy. The breadth of its proposals makes it daunting to assess the GND using the standard tools of policy analysis. Nevertheless, this short paper is an initial foray. We have three broad conclusions:

  • The GND’s proposed goals, “mobilization,” and specific policy projects encompass social and institutional changes far exceeding the narrow policy goals, but these changes are impossible to quantify at this point;
  • Many of the policies proposed in the GND are redundant with other aspects in it, which also complicates a precise analysis, as the interactions are difficult to predict; and
  • The GND will be very expensive – our initial estimates for the tractable aspects (best thought of as estimating the order of magnitude) are summarized below.

The phase relations among atmospheric CO content, temperature and global ice volume over the past 420 ka

The phase relations (leads/lags) among atmospheric CO2 content, temperature and global ice volume are key to understanding the causes of glacial-interglacial (G-IG) climate transitions. Comparing the CO2​ record with other proxy variables from the Vostok ice core and stacked marine oxygen isotope records, allows the phase relations among these variables, over the last four G-IG cycles, to be estimated. Lagged, generalized least-squares regression provides an efficient and precise technique for this estimation. Bootstrap resampling allows account to be taken of measurement and timescale errors. Over the full 420 ka of the Vostok record, CO2 variations lag behind atmospheric temperature changes in the Southern Hemisphere by 1.3 ± 1.0 ka, and lead over global ice-volume variations by 2.7 ± 1.3 ka. However, signicant short-term changes in the lag of CO2 relative to temperature, subsequent to Terminations II and III, are also detected.

Climate Impact of Increasing Atmospheric Carbon Dioxide

The global temperature rose by 0.20C between the middle 1960’s and
1980, yielding a warming of 0.4°C in the past century. This temperature increase is
consistent with the calculated greenhouse effect due to measured increases of
atmospheric carbon dioxide. Variations of volcanic aerosols and possibly solar
luminosity appear to be primary causes of observed fluctuations about the mean trend
of increasing temperature. It is shown that the anthropogenic carbon dioxide warming
should emerge from the noise level of natural climate variability by the end of the
century, and there is a high probability of warming in the 1980’s. Potential effects on
climate in the 21st century include the creation of drought-prone regions in North
America and central Asia as part of a shifting of climatic zones, erosion of the West
Antarctic ice sheet with a consequent worldwide rise in sea level, and opening of the
fabled Northwest Passage.

Assessing human impacts on climate and biodiversity requires an understanding of the relationship between the concentration of carbon dioxide (CO2) in the Earth’s atmosphere and global temperature (T). Here I explore this relationship empirically using comprehensive, recently-compiled databases of stable-isotope proxies from the Phanerozoic Eon (~540 million years before the present) and through complementary modeling using the atmospheric absorption/transmittance code MODTRAN. Atmospheric CO2 concentration is correlated weakly but negatively with linearly-detrended T proxies over the last 425 million years. Of 68 correlation coefficients (half non-parametric) between CO2 and T proxies encompassing all known major Phanerozoic climate transitions, 77.9% are non-discernible (p > 0.05) and 60.0% of discernible correlations are negative. Marginal radiative forcing (ΔRFCO2), the change in forcing at the top of the troposphere associated with a unit increase in atmospheric CO2 concentration, was computed using MODTRAN. The correlation between ΔRFCO2 and linearly-detrended T across the Phanerozoic Eon is positive and discernible, but only 2.6% of variance in T is attributable to variance in ΔRFCO2. Of 68 correlation coefficients (half non-parametric) between ΔRFCO2 and T proxies encompassing all known major Phanerozoic climate transitions, 75.0% are non-discernible and 41.2% of discernible correlations are negative. Spectral analysis, auto- and cross-correlation show that proxies for T, atmospheric CO2 concentration and ΔRFCO2 oscillate across the Phanerozoic, and cycles of CO2 and ΔRFCO2 are antiphasic. A prominent 15 million-year CO2 cycle coincides closely with identified mass extinctions of the past, suggesting a pressing need for research on the relationship between CO2, biodiversity extinction, and related carbon policies. This study demonstrates that changes in atmospheric CO2 concentration did not cause temperature change in the ancient climate.
