Abstract

Recent research developments are explained on the paleoenvironmnet, which is elucidated by the deep ice core analysis, and on the cryosphere changing due to the global warming. The 2503m and 3035m deep ice cores were drilled in Dome Fuji, Antarctica, and the glacial-interglacial cycles with the periodic air temperature variation of 20, 40 and 100 thousand years cycles were recognized clearly. Cryosphere changing are especially remarkable in the Northern Hemisphere. There are many scientific reports dealing with the sea ice extent decreasing in the Arctic sea, the mountain glacier retreat, and the permafrost degradation. We need the reliable data accumulation which serves as the basis of scientific discussions.
