Statement of Prof. Zbigniew Jaworowski
Chairman, Scientific Council of Central Laboratory for Radiological Protection Warsaw, Poland
I am a Professor at the Central Laboratory for Radiological Protection (CLOR) in Warsaw, Poland, a governmental institution, involved in environmental studies. CLOR has a “Special Liaison” relationship with the US National Council on Radiological Protection and Measurements (NCRP). In the past, for about ten years, CLOR closely cooperated with the US Environmental Protection Agency, in research on the influence of industry and nuclear explosions on pollution of the global environment and population. I published about 280 scientific papers, among them about 20 on climatic problems. I am the representative of Poland in the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), and in 1980 – 1982 I was the chairman of this Committee. 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.
