Climate science is a productive pursuit with Nobel Prizes, an Oscar, billions in research funding, massive tax grabs and wealth for exploiters. Continuation of these activities partly validated the claim the disclosed files from the Climatic Research Unit (CRU) at the University of East Anglia (UEA) are of small consequence.
As I wrote earlier the scandal at CRU (Climategate) is diverting from the real scandal, which is the claim CO2 is causing warming and climate change. Climategate is the greatest orchestrated fraud in scientific history, but claims about CO2 are the greatest fallacy. Climategate lets those who’ve known what was happening to avoid being ignored as conspiracy theorists.
Everyone incorrectly talks about carbon when they mean CO2, which was the original focus of the claim human industrial activity was causing global warming. Theory assumed CO2 was a greenhouse gas that slowed heat escaping to space. As it increases temperature rises and it would because of increased industrial activity. This became fact immediately and challenging scientists were pushed aside. Mostly by nasty attacks from those who falsified records, rewrote historic records, distorted and misused science and statistics as the leaked CRU emails attest. Now they, their supporters, and all those benefiting, work to perpetuate the massive deception.
Some of this article was presented in a 2008 piece, but the CRU revelations make a revisit important. The summary of work the IPCC represents is only that chosen by the IPCC to achieve their goal. Remember the email comments about including or excluding articles that supported their objective.
Claims now proven false include;
The last claim is basic to the argument that humans are causing warming and climate change by increasing the levels of atmospheric CO2.
In a paper submitted to a US Senate Committee on Commerce, Science, and Transportation hearing Professor Zbigniew Jaworowski explains,“The basis of most of the IPCC conclusions on anthropogenic causes and on projections of climatic change is the assumption of low level of CO2 in the pre-industrial atmosphere. This assumption, based on glaciological studies, is false.” This means more when you know that Tom Wigley, who is the heart of the CRU gang, introduced the 280 ppm number to the climate science community with a 1983 paper titled, “The pre-industrial carbon dioxide level.” (Climatic Change 5, 315-320). He based his work on studies by G. S. Callendar (1938) of thousands of direct measures of atmospheric CO2 beginning in 1812. Callendar rejected most of the records, including 69% of the 19th century records and only selected records that established 280 ppm as the pre-industrial level. Here’s a plot of the records with Callendar’s selections circled.

Selections changed the slope of the trend from declining to increasing. As Jaworowski notes, “The notion of low pre-industrial CO2 atmospheric level, based on such poor knowledge, became a widely accepted Holy Grail of climate warming models. The modelers ignored the evidence from direct measurements of CO2 in atmospheric air indicating that in 19th century its average concentration was 335 ppmv.”
Ice cores provide the historic record and samples from Mauna Loa provide the recent record. Both are drastically smoothed thus eliminating variability. This was done to tie in with the pre-industrial levels. Ernst Beck confirmed Jaworowski’s research in a September 2008 article in Energy and Environment and validated all the 19th century records. In a devastating conclusion Beck writes,“Modern greenhouse hypothesis is based on the work of G.S. Callendar and C.D. Keeling, following S. Arrhenius, as latterly popularized by the IPCC. Review of available literature raise the question if these authors have systematically discarded a large number of valid technical papers and older atmospheric CO2 determinations because they did not fit their hypothesis? Obviously they use only a few carefully selected values from the older literature, invariably choosing results that are consistent with the hypothesis of an induced rise of CO2 in air caused by the burning of fossil fuel.”
Pre-industrial levels were 50 ppm higher than those used in the IPCC computer models. Models also incorrectly assume uniform atmospheric distribution and virtually no variability from year to year. Beck found, “Since 1812, the CO2 concentration in northern hemispheric air has fluctuated exhibiting three high level maxima around 1825, 1857 and 1942 the latter showing more than 400 ppm.” Here is a plot from Beck comparing 19th century readings with ice core and Mauna Loa data.

Difference in variability of the 19th century measures, ice core records and Mauna Loa are apparent. Ice core records are subjected to a 70-year smoothing average eliminating a great deal of information. For example, the Mauna Loa record covers 50 years (1958 – 2009), not enough for even a single point. Elimination of high readings prior to the smoothing makes the loss even greater. As with all known records the temperature changes before the CO2, here by approximately 5 years.
Elimination of data occurs with the Mauna Loa readings, which can vary up to 600 ppm in the course of a day. Beck explains how Charles Keeling established the Mauna Loa readings by using the lowest readings of the afternoon. He ignored natural sources, a practice that continues. Beck presumes Keeling decided to avoid these low level natural sources by establishing the station at 4000 meters up the volcano. As Beck notes “Mauna Loa does not represent the typical atmospheric CO2 on different global locations but is typical only for this volcano at a maritime location in about 4000 m altitude at that latitude.” (Beck, 2008, “50 Years of Continuous Measurement of CO2 on Mauna Loa” Energy and Environment, Vol 19, No.7.) Keeling’s son continues to operate the Mauna Loa facility and as Beck notes, “owns the global monopoly of calibration of all CO2 measurements.” Since Keeling is a co-author of the IPCC reports they accept Mauna Loa without question.
Jaworowski estimates the ice core readings are at least 20% low, which is reasonable given the CO2 levels for 600 millions years using geologic evidence.

Current level of 385 ppm on the right of the graph (Figure 3) is the lowest in the entire record only equaled by a period between 315 and 270 million years ago (mya).
Further evidence of the effects of statistical smoothing and the artificially low ice core readings are provided by measurements of stomata. Stomata are the small openings on leaves that vary directly with the amount of atmospheric CO2. A comparison of a stomata record with the ice core record for a 2000-year period illustrates the issue.
Figure 4: Ice core CO2 levels compared to Stomata over 2000 years.
Stomata data on the right show higher readings and variability than excessively smoothed ice core record on the left. The stomata record aligns with the 19th century measurements as Jaworowski and Beck assert. A Danish stomata record shows levels of 333 ppm 9400 years ago and 348 ppm 9600 years ago.
EPA declared CO2 a toxic substance and a pollutant. Governments prepare carbon taxes and draconian restrictions crippling economies for a completely non-existent problem. Failed predictions, discredited assumptions, incorrect data did not stop insane policies. Climategate revealed the extent of corruption so more people understand malfeasance and falsities only experts knew or suspected. More important, they are not rejected as conspiracy theorists. Credibility should have collapsed, but political control and insanity persists – at least for a little while longer.
