| Abstract: | The abrupt change of climate discovered within recent years mainly occurred within glacial period or transition period from cold to warm,which were assumed caused by the melting and freezing process of the huge ice sheet,these processes drove the vertical oceanic circulation and resulted the abrupt climate change.However,it has been found that the abrupt events also characterized in Eemain and Holocene more recently,particularly at low to mid latitudes,which was supposed as a climatic stable episode.The evidences from Greenland and France show there were some abrupt events embedded in Eemain: And the evidences from Chinese Historical writings show there was an abrupt event around 1230 AD,which was also identified by the other proxy data from China,including the lake sediment from Lake Kunming in Beijing,ice core from Guliya in Tibet Plateau and salt lake sediment from Lake Hetong chahan and Lake Hammer in Inner Mongolia.Moreover,the abrupt event around 1230 AD was identified by evidences from North America and Europe. These evidences suggest that the abrupt climatic event around 1230 AD occurred not only in China but also in Europe and America.The implication for the mentioned results suggests that the climate in Holocene is also unstable and that the instability of the climate for coming century may increase. |
