抄録

Recent results from Greenland deep ice core studies have revealed 24 glacial interstadials which are characterized by large (a range of 5-7°C) and abrupt climate changes over a few decades, called the Dansgaard-Oeschger cycle. Massive iceberg discharge (Heinrich event) was followed by Bond cycle bounding of Dansgaard-Oeschger cycles. By reviewing recent studies, the present paper emphasizes two stable modes in the global climate system, and the role of thermohalaine in the occurrence of abrupt warming during the last glacial period. Furthermore, the possibility of a shift of the current climate mode to another resulting from an increase in precipitation due to the current global warming and the cessation of thermohaline circulation is introduced.
