Climate change during the last interglacial period draws much attention because of similarity of climatic features between the current and last interglacials, regarded as a likely analogue to future projected climate. It’s suggested that the west Kunlun Mountains may be the only place in the west China to recover ice cores with a potential age reaching the last interglacial period. Here we make use of two drilled ice cores to-the-bottom (with length of 135.30 m and 131.92 m, respectively) and another two proposing ice cores to-the-bottom from the thickest site (>210 m, which was deduced from the penetratign radio sounding results) of the Chongce Ice Cap in the west Kunlun Mountains, for performing multi-type and high-resolution time series of climatic proxies. The climatic change since the last interglacial period will be reconstructed based on a reliable ice core dating by applying novel methods. Moreover, we will perform a detailed survey on the Chongce Ice Cap to decipher its dynamic features, and ascertain the coverage of the ancient glaciers in the west Kunlun since the last glacial to understand their response to the past climatic conditions that were reconstructed by the ice cores and the other kinds of climatic archives. Our results might have important implications for future climtic prediction and mountainous glacier variation.
