A new climate record from the Qinghai-Tibetan Plateau suggests that the hydrologic record of the area is linked to changes in the Indian Monsoon and Westerlies. Drawing from lacustrine sediment cores in the source area of the Yellow River, the 1500-year record reflects the major global climate phases of the period covered by the study and correlates with other paleoclimate records from the region. These hydrological and climate variables are also studied in conjunction with changes to the chemical composition of the water and the organic matter contained within it. Read the full study here .
