THE CLIMATE HUSTLE:

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 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.
