The “Global Climate Strike” mobilized 4 million protestors around September 20. When former President Barack Obama met with 16-year-old Swedish “climate activist” Greta Thunberg, it made the entire issue look more like political theater than science.
The ‘climate strike’ protestors are pressuring international government meetings to take more drastic action. Others observe from polling that the hard sell of the climate change hoax may be a red flag turning some people off.
However, there is a fatal flaw in the climate change alarmism. Actually there are many fatal flaws. But there is one that anyone can understand. It cannot be cured by the alarmists.
We actually do not know how much carbon dioxide was in Earth’s atmosphere prior to the 1930s. Devices to reliably measure carbon dioxide in the air went through painstaking, slow, bumpy development. Instruments did not really come into their own until around 1930.
Because we don’t know the carbon dioxide content of the atmosphere, climate change proponents depend upon unreliable “proxies.” They substitute gas pockets retrieved from ice core samples from deep within ancient glaciers. They hope this will tell us Earth’s ancient atmosphere and the concentration of CO2 in the air.
Speculation that air pockets remain exactly the same over hundreds to millions of years has never been tested. And what is the margin of error of an ice core sample?
Arguing that A causes B requires measurements with a known margin of error. We can’t model a phenomenon in inches if the data was measured in miles. Proxy measurements from ice core air samples cannot prove global warming caused by carbon dioxide. The margins of error are too wide and highly unpredictable.
In 2004 the U.S. Senate was fully briefed on the falsehood of man-made global warming. The U.S. Government clearly knows that we cannot measure carbon dioxide earlier than 1900 to 1930.
Prof. Zbigniew Jaworowski testified before the U.S. Senate on March 13, 2004:
Improper manipulation of data, and arbitrary rejection of readings that do not fit the pre-conceived idea on man-made global warming is common in many glaciological studies of greenhouse gases. In peer reviewed publications I exposed this misuse of science.
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. Therefore IPCC projections should not be used for national and global economic planning.
Prof. Zbigniew Jaworowski. Chairman, Scientific Council of Central Laboratory for Radiological Protection, Warsaw, Poland, Statement before the US Senate Committee
on Commerce, Science, and Transportation, March 19, 2004
Prof. Zbigniew Jaworowski explained his qualifications to the Senate:
For the past 40 years I was involved in glacier studies, using snow and ice as a matrix for reconstruction of history of man-made pollution of the global atmosphere. A part of these studies was related to the climatic issues.
Ice core records of CO2 have been widely used as a proof that, due to man’s activity the current atmospheric level of CO2 is about 25% higher than in the pre-industrial period. These records became the basic input parameters in the models of the global carbon cycle and a cornerstone of the man-made climatic warming hypothesis.
These records do not represent the atmospheric reality, as I will try to demonstrate in my statement.
In order to study the history of industrial pollution of the global atmosphere, between 1972 and 1980, I organized 11 glacier expeditions, which measured natural and man-made pollutants in contemporary and ancient precipitation, preserved in 17 glaciers in Arctic, Antarctic, Alaska, Norway, the Alps, the Himalayas, the Ruwenzori Mountains in Uganda, the Peruvian Andes and in Tatra Mountains in Poland.
In the 1990s I was working in the Norwegian Polar Research Institute in Oslo, and in the Japanese National Institute of Polar Research in Tokyo. In this period I studied the effects of climatic change on polar regions, and the reliability of glacier studies for estimation of CO2 concentration in the ancient atmosphere.
Prof. Jaworowski explained why chemistry, including intense pressure under the weight of layers of glacial ice, change the air sample from its original composition:
More than 20 physico-chemical processes, mostly related to the presence of liquid water, contribute to the alteration of the original chemical composition of the air inclusions in polar ice.
One of these processes is formation of gas hydrates or clathrates. In the highly compressed deep ice all air bubbles disappear, as under the influence of pressure the gases change into the solid clathrates, which are tiny crystals formed by interaction of gas with water molecules. Drilling decompresses cores excavated from deep ice, and contaminates them with the drilling fluid filling the borehole.
* * * After decompression of the ice cores, the solid clathrates decompose into a gas form, exploding in the process as if they were microscopic grenades. In the bubble-free ice the explosions form a new gas cavities and new cracks. Through these cracks, and cracks formed by sheeting, a part of gas escapes first into the drilling liquid which fills the borehole, and then at the surface to the atmospheric air.
* * * This leads to depletion of CO2 in the gas trapped in the ice sheets. This is why the records of CO2 concentration in the gas inclusions from deep polar ice show the values lower than in the contemporary atmosphere, even for the epochs when the global surface temperature was higher than now.
Similarly, the ice is “contaminated” with algae and microbes. “Bacteria form in the ice releasing gases even in 500,000-year-old ice at great depth. Brent C. Christner, “Detection, Recovery, Isolation and Characterization of Bacteria in Glacial Ice and Lake Vostok Accretion Ice,” Dissertation. Ohio State University, 2002.
To use ice core samples as a measurement for Earth’s ancient atmosphere, we would have to to measure a known sample within ice layers, wait a million years, and then come back a million years later and re-test the air pocket. It is unlikely that the gas sample will remained unchanged. That would be the kind of real science that the protesting students could have learned had they stayed in school.
As one scientist put it: “The hypothesis that global warming and climate change are due to human addition of carbon dioxide (CO2) to the atmosphere became fact before research had even begun.” (Emphasis in the original.)
