It was reported that since 1850 human activities have increased the CO₂ content of the terrestrial atmosphere from 290 ppm to slightly more than 330 ppm. It is thought that the CO₂ content would reach twice the current CO₂ content by the year 2020 and at that time there will have been a rise in the average air temperature of about 2℃. This has produced a serious fear that a climatic change will occur and reduce some of the present granary regions to rather arid areas. Thus atmospheric CO₂ studies should be one of the most urgent research subjects internationally. Y. Kitano has organized the research group on "The cycle of carbon dioxide through the phases of the atmosphere, hydrosphere and biosphere" in connection with the atmospheric CO₂ problem, sponsored by the Ministry of Education in Japan as a Special Project Research on Environmental Sciences. It is happy to show the results obtained by some members of the research group here.
