The man-made climate warming hypothesis is based on the assumption that mainly through burning fossil fuels the pre-industrial level of CO2 of about 290 ppmv has increased by about 30%. However this assumption is at odds with direct measurements of CO2 over the past 200 years. Furthermore recent estimates of pre-industrial levels of CO2 have been largely based on analyses of polar ice cores which do not fulfil the essential closed-system criteria required for reliable reconstruction of the pre-industrial and ancient atmosphere. Prof. Jaworowski will discuss the problems of ice core analyses including differential solubility of gases and the formation and decomposition of various clathrates as pressures increase with depth or are released by removal of ice cores.
Zbigniew Jaworowski, M.D., Ph.D., D.Sci., is a professor at the Central Laboratory for Radiological Protection In Warsaw. A multidisciplinary scientist, he has studied pollution of the global atmosphere and population with radio-nuclides and heavy metals. He is a representative of Poland in the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), and served as its Chairman in 1980-1981. In 1986 he was a member of the Polish Governmental Commission for mitigation of the effects of Chernobyl catastrophe. He was a member or chairman of about 20 advisory groups of the IAEA and UNEP. He has authored about 300 scientific papers, and organized 10 scientific expeditions on 17 glaciers in both hemispheres.
