More politically incorrect light (and data) concerning global warming --- that runs counter to the presumptions from Al Gore (inventor of the internet) J
It is important for some folks to look at the data , because our elected representatives are reacting to power point slide presentations and sound bytes
How many failed predictions, discredited assumptions and evidence of incorrect data are required before an idea loses credibility? CO2 is not causing warming or climate change. It is not a toxic substance or a pollutant. Despite this President Elect Obama met with Al Gore on December 9 no doubt to plan a climate change strategy based on these problems. They make any plan to reduce of CO2 completely unnecessary.
Proponents of human induced warming and climate change told us that an increase in CO2 precedes and causes temperature increases. They were wrong. They told us the late 20th century was the warmest on record. They were wrong. They told us, using the infamous “hockey stick” graph, the Medieval Warm Period (MWP) did not exist. They were wrong. They told us global temperatures would increase through 2008 as CO2 increased. They were wrong. They told us Arctic ice would continue to decrease in area through 2008. They were wrong. They told us October 2008 was the second warmest on record. They were wrong. They told us 1998 was the warmest year on record in the US. They were wrong it was 1934. They told us current atmospheric levels of CO2 are the highest on record. They are wrong. They told us pre-industrial atmospheric levels of CO2 were approximately 100 parts per million (ppm) lower than the present 385 ppm. They are wrong. This last is critical because the claim is basic to the argument that humans are causing warming and climate change by increasing the levels of atmospheric CO2 and have throughout the Industrial era. In fact, pre-industrial CO2 levels were about the same as today, but how did they conclude they were lower?
In a paper submitted to the Hearing before the US Senate Committee on Commerce, Science, and Transportation Professor Zbigniew Jaworowski explains,
Most people don’t know that thousands of direct measures of atmospheric CO2 were made beginning in 1812. Scientists took the readings with calibrated instruments and precise measurements as the work of Ernst-Georg Beck has thoroughly documented. Guy Stewart Callendar was an earlier visitor to these records. He rejected most of the records including 69% of the 19th century records and only selected certain records that established the pre-industrial level as 280 ppm. Here is a plot of the records with those Callendar selections circled.
It is clear how only low readings were chosen. Also notice how the slope and trend is changed compared to the entire record.
As Jaworowski notes,
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.
Compare the variability of the atmospheric measures with the smooth line of the ice core record. Eliminating extreme readings and then applying a long term smoothing average achieved this. When smoothing is done on the scale of the ice core record a great deal of information is lost. Elimination of high readings prior to the smoothing makes the loss even greater. Also note that as with all known records the temperature changes before the CO2, in this record by approximately 5 years.
Elimination of data is also done with the Mauna Loa and other atmospheric 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 (m) 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 the young Keeling is a co-author of the IPCC reports they accept the version that Mauna Loa is representative of global readings and that they reflect an increase since pre-industrial levels.
Jaworowski estimates the ice core readings are at least 20% low. That is more reasonable given the CO2 levels for 600 millions years using geologic evidence. Here the current level of 385 ppm is the lowest in the entire record and only equaled by a period between 315 and 270 million years ago (mya).
There are many problems with the ice core record. It takes years, sometimes up to 80, for air to be trapped in the ice so the question is what is actually being trapped and measured? Melt water moving through the ice especially when the ice is close to the surface can contaminate the air bubble. Bacteria form in the ice releasing gases even in 500,000-year-old ice at great depth. Under the pressure below 50m ice changes from brittle to plastic and begins to flow. The layers formed with each year of snowfall gradually disappear as the ice layers meld and compress. A considerable depth of ice covering a long period of time is required to obtain a single reading at depth.
Further evidence of the effects of 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.
Stomata data on the right show the higher readings and variability when compared to the excessively smoothed ice core record on the left. This aligns quantitatively 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.
The EPA is planning to declare CO2 a toxic substance and a pollutant. Governments are preparing to create carbon taxes and draconian restrictions that will cripple economies for a completely non-existent problem. It appears that a multitude of failed predictions, discredited assumptions and pieces of incorrect data are required before an idea loses credibility. Credibility should have collapsed but political control and insanity prevail.

Pre-industrial CO2 levels were about the same as today. How and why we are told otherwise?
By Dr. Tim Ball Wednesday, December 10, 2008
How many failed predictions, discredited assumptions and evidence of incorrect data are required before an idea loses credibility? CO2 is not causing warming or climate change. It is not a toxic substance or a pollutant. Despite this President Elect Obama met with Al Gore on December 9 no doubt to plan a climate change strategy based on these problems.

This last is critical because the claim is basic to the argument that humans are causing warming and climate change by increasing the levels of atmospheric CO2 and have throughout the Industrial era. In fact, pre-industrial CO2 levels were about the same as today, but how did they conclude they were lower?
In a paper submitted to the Hearing before the US Senate Committee on Commerce, Science, and Transportation 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.”Ice cores provide the historic record and data collected at Mauna Loa the recent record. Both records are drastically modified to produce a smooth continuous curve with little variability. This was necessary to confirm the evidence falsely concluded from many 19th century measures that pre-industrial levels were approximately 280 ppm and didn’t vary much. So how did they engineer the smooth curves and ignore the fact the 19th century record shows a global average of 335 ppm and considerable variability from year to year.
Most people don’t know that thousands of direct measures of atmospheric CO2 were made beginning in 1812. Scientists took the readings with calibrated instruments and precise measurements as the work of Ernst-Georg Beck has thoroughly documented. Guy Stewart Callendar was an earlier visitor to these records. He rejected most of the records including 69% of the 19th century records and only selected certain records that established the pre-industrial level as 280 ppm. Here is a plot of the records with those Callendar selections circled.
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.”Beck recently confirmed Jaworowski’s research. A September 2008 article in Energy and Environment examined the readings in great detail and validated the 19th century findings. 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.So the pre-industrial level is at least 50 ppm higher than the level put into the computer models that produce all future climate predictions. The models also incorrectly assume uniform atmospheric global distribution and virtually no variability of CO2 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.

Here the current level of 385 ppm is the lowest in the entire record and only equaled by a period between 315 and 270 million years ago (mya).
