An ice core record from the Guliya ice cap on the Qinghai-Tibetan Plateau provides evidence of regional climatic conditions over the last glacial cycle. ~(36)Cl data suggest that the deepest 20 meters of the core may be more than 500,000 years old. The δ~(18)O change across Termination I is ~5.4 per mil, similar to that in the Huascaran (Peru) and polar ice cores. Three Guliya interstadials (Stages 3, 5a, and 5c) are marked by increases in δ~(18)O values similar to that of the Holocene and Eemian (~124,000 years ago). The similarity of this pattern to that of CH_4 records from polar ice cores indicates that global CH_4 levels and the tropical hydrological cycle are linked. The Late Glacial Stage record contains numerous 200-year oscillations in δ~(18)O values and in dust, NH_4~+, and NO_3~- levels.
