This study firstly reviewed the achievements about climate change in the north Altay Mountains over the past 2 000 years,and then summarized the geographical consistency of climate information contained in these documents. Mutil-proxies (lake cores, tree rings and ice cores) recorded the five important climatic events in the Northern Hemisphere, including the Roman Optimum (0 - 400 AD) ,Dark Age Cold Period (400 - 600 AD) ,Medieval Warm Period (800 - 1200 AD) ,Little Ice Age (1400 - 1860 AD) ,and recent warming period (since 1860 AD) . These climatic events were mainly modulated by solar activity-dominated solar radiation variations in the past 2 000 years and recent warming period since 1860 AD,which were largely attributable to an increase of CO_2 concentration in the past 150 years. The precipitation history in the north Altay Mountains over the past 2 000 years indicated that these periods including 0 - 450, 600 - 800, 1050 - 1300, 1650 - 1860 AD were characterized by high precipitation, and those including 450 - 600, 800 - 1050, 1300 - 1650, 1860 - 2000 AD were featured by low precipitation. In addition, the combination of temperature and precipitation in the north Altay Mountains over the past 2 000 years did not supported thecold-wet and warm-dryhydrothermal configuration in the arid zone in Central Asia.
