Abstract
Over the last million years, the Earth climate displayed a quite cyclic variability, with an alternance of glacial and interglacial periods in direct connection to the insolation cycles. Over the last 60,000 years, however, it is well established now that time to time, these regular cycles were interrupted by sudden abrupt climatic changes: the so-called Heinrich events, the Dansgaard-Oeschger cycles, the Younger Dryas, the 8.2ka event, etc. Since 1988, more than a hundred of papers were published on that topic. In order to explain the origin of these events, a few authors proposed different hypotheses. Nowadays, the international community did not reach any consensus yet. This paper proposes a review of the recent findings and hypotheses related to that question.Keywords
