The abrupt climate events happened at about 550 AD and 1000 AD are of very important significance in climate changes of southern Xinjiang during the last 2\^0 ka, which indicated that the climate was ever re-arranged greatly.
High-resolution geochemical, physical and biological proxies from the lake sediments indicate that there is a strong cold climate event in the Early to Middle Holocene transition (EMHT) characterized by weak weathering (sediments with higher Rb/Sr ratios) in single watershed, lake productivity decrease and lower lake level.
According to the research result on the climate change during the past 2000a, the authors have compared the climate change record during the past 2000a in Luobupo with the climate change records in different regions and of different types by means of remote sensing, exploring the responding mechanism of climatic event in modern saline, and having proved that the climatic changing curve in the deposits in Luobupo is of definite paleoclimate meaning.
With the record of high-resolution of the Chinese loess section at Yuanbao in Linxia,boundary age constituted three age models based on the climatic events,namely the boundary age of MIS1/2 at 2.3m is 11.5kaBP and the boundary age of MIS3/4 at 21.4m is 59.8kaBP. The boundary ages were determined in accordance with the latest research results,i. e.
It should be noted that a fast cooling event at 72 ka BP in the stalagmite isotopic record approximately coincides to the Toba eruption event in Indonesia, probably sug-gesting that the global climatic events during the late Pleistocene could not be fully explained with the wanning and waxing of the North Atlantic deep water.
石笋稳定同位素曲线上72 ka BP左右的快速降温事件与印度尼西亚 Toba火山喷发事件基本一致,有可能说明晚更新世全球气候事件的发生并非单一源于北大西洋深层水体的变化。
It responded to regional environmental changes and global abrupt climate events, following the westerly climate change mode on 100-year-scale, primarily with cold-wet and warmdry characteristics.
Some analyses show that frequency and magnitude of extreme weather and climate events have also undergone significant changes in the past 50 years or so.
Extreme climate events, migration for cultivation and policies: A case study in the early Qing Dynasty of China
The frequent changes of the policy on the years when taxation started after the land was cultivated were also related to climate events.
The extreme climate events in North China, migration to Northeast China for cultivation, and the related management policies showed an impact-response chain, which reflected the interaction among extreme climate events, human behavior, and policies.
This early Holocene climatic event is referred to as the Palü Oscillation (Palü-Schwankung) and is considered to be broadly contemporaneous with the previously described Schlaten Oscillation (Schlate n-Schwankung) in the Austrian Alps.
Avian reproductive failure in response to an extreme climatic event
Drought is considered to be an extreme climatic event causing significant damage both in the natural environment and in human lives.
627-629 climatic cooling event also improved our understanding of another problem: was the climatic event due to the impact of a ca.
The severity of these impacts depends on the intensity and duration of the climatic event, social organization, and the prevailing socioeconomic conditions at the time of the climatic extreme.
Variations in the physical properties were used to recognize synchronous formation of sediment horizons corresponding to certain formation stages of the reservoir soil complex and anomalous environmental and climatic events.
As is established, climatic events recognizable in the Baikal sedimentary record are correlative with interglacial and glacial epochs detectable in volcanic lavas of the East Sayan Mountains.
The peat archives in this area recorded some hemispheric climatic events, such as three new ice ages and the Medieval Warm Period occurring in the northern hemisphere.
14C geochronology of rapid climatic events during the glacial-holocene transition
As an example, the conservation of the Petite Terre (Guadeloupe) Iguana delicatissima population requires identifying both the mechanisms that regulate its population and their relationships to catastrophic climatic events.
This paper documents methods of evaluating the climatic information extracted from Chinese historical literatures. Relevant sources include local gazettes, official histories, memorial to the emperor and personal and private writings. Some indexes has been developed to modify climatic information in three aspects, they are: the time interval between the climatic event occurred and when it was recorded, the distanc between the event and where it was recorded, and the ability in language of the writer's explanation....

Owing to the sea level falling in late Miocene and late Pliocene, the islands in the Xisha region were exposed and subjected to dolomitization, forming secondary dolomites of tens of meters thick. The dolomites in the two horizons mentioned above are traceable in space, related to hiatus and no selection to rock types. Because of the dolomitization, Sr was moved away, δ18O kept normal and δ13C became heavier. The dorag model was used to interprete the features mentioned.
The climatic evolution in Quaternary is an attractive scientific subject, especially the palaeoclimatic change over the Qinghai-Xizang (Tibet) Plateau has drawn the attention of scholars at home and abroad. The plateau which is covered by the vast arid-semiarid region developes many salt lakes. These salt lakes contain affluent information about palaeoclimatic change and is of importance in the study of the arid-semiarid region.
