In recent decades, the rapidly changing climate environment in the Tibetan Plateau (TP) poses significant challenges to human survival and future sustainable development. The suitability and stability of the climate in the TP undoubtedly affected the living conditions and welfare of prehistoric humans. However, few studies have attempted to link cl...

The Yarlung Tsangpo, the longest river in the southern Tibetan Plateau (TP), has attracted much research attention aimed at understanding the factors controlling its modern hydrology and possible future discharge in the context of ongoing climate change. However, partly due to the complex regional climatic background, no consistent conclusions have...

During the 7-9th century, the Tibetan Empire constituted a superpower between the Tang Empire and Abbasid Caliphate: one that played significant roles in geopolitics in Asia during the Early Medieval Period. The factors which led to the rise and rapid decline of this powerful Empire, the only united historical regime on the Tibetan Plateau (TP), re...

Lake sediments are valuable archives to investigate past changes in climate and environment on various timescales. Closed-basin lakes can be regarded as precipitation gauges, which are ideal for studying past climate changes. However, the climatic implications of various sedimentary proxy indicators from closed-basin lakes are often confounded by l...

Knowledge of paleotemperature variation in the Tibetan Plateau (TP) can provide potential insights to evaluate the future climate change under ongoing global warming and to improve our understanding of the controversial Holocene temperature changes between stacked proxy and model simulation. Here, we present a 115-yr-resolution record of bGDGTs (br...

Both the Indian Summer Monsoon (ISM) and glacier meltwater are suggested to significantly influence the modern discharge of the Yarlung Tsangpo River, which is the longest river of Tibet and is an important freshwater source for the local population as well as for the large populations in India and Bangladesh in the lower reaches. Understanding pas...

Lake sediments on the Tibetan Plateau are important natural archives for studying past climate and environment changes. A precise sediment core chronology is a fundamental prerequisite for reconstructing past climate and environment changes. However, radiocarbon dates on bulk carbon in lake sediment cores are subject to “old carbon” reservoir effec...

In recent decades, there have been discussions and predictions regarding the impact of warming climate on floods, due to its socioeconomic and environmental consequences. For accurate prediction of future floods events and its impact, it is crucial to have an improved understanding on past floods event. Lacustrine sediments have been used as a natu...

The Asian summer monsoon and the mid-latitude Westerlies are major atmospheric circulation systems which influence the climate of the Tibetan Plateau (TP), and hence the water resources, ecology, and socioeconomic well-being of the region. The interplay between the monsoon and the Westerlies has been investigated on glacial–interglacial, millennial...
