Is the chairman of the Scientific Council of the Central Laboratory for Radiological Protection in Warsaw. In the winter of 1957-1958, he measured the concentration of CO₂ in the atmospheric air at Spitsbergen. During 1972 to 1991, he investigated the history of the pollution of the global atmosphere, measuring the dust preserved in 17 glaciers—in the Tatra Mountains in Poland, in the Arctic, Antarctic, Alaska, Norway, the Alps, the Himalayas, the Ruwenzori Mountains in Uganda, and the Peruvian Andes. He has published about 20 papers on climate, most of them concerning the CO₂ measurements in ice cores.
