沙尘在气候变化中起着重要作用，因为它可以改变大气环流以及全球地球化学和水文循环。许多研究调查了灰尘和温度之间的关系，试图预测未来几十年到几个世纪的全球变暖是否会导致未来灰尘减少或增加。然而，尘埃和温度变化很少在同一记录中同时重建。在这里，我们提出了一个1600年长的温度和尘埃活动的定量记录推断同时从多纹库赛湖沉积物在北方青藏高原，中国西北部。在年代际时间尺度上，我们的温度重建与巴基斯坦喀喇昆仑树轮记录以及中国和北半球基于代理记录的温度重建基本一致。未来沙尘活动的强弱取决于北方青藏高原的温度变化，即沙尘活动的强弱与6 - 7 - 8月的低温和高温（JJA平均温度）有很好的相关性。这种相关性意味着青藏高原北方夏季风和冬季风的增强应同时发生。
Dust plays an important role in climate changes as it can alter atmospheric circulation, and global biogeochemical and hydrologic cycling. Many studies have investigated the relationship between dust and temperature in an attempt to predict whether global warming in coming decades to centuries can result in a less or more dusty future. However, dust and temperature changes have rarely been simultaneously reconstructed in the same record. Here we present a 1600-yr-long quantitative record of temperature and dust activity inferred simultaneously from varved Kusai Lake sediments in the northern Qinghai–Tibetan Plateau, NW China. At decadal time scale, our temperature reconstructions are generally in agreement with tree-ring records from Karakorum of Pakistan, and temperature reconstructions of China and North Hemisphere based on compilations of proxy records. A less or more dusty future depends on temperature variations in the Northern Qinghai-Tibetan Plateau, i.e. weak and strong dust activities at centennial time scales are well correlated with low and high June–July–August temperature (average JJA temperature), respectively. This correlation means that stronger summer and winter monsoon should occur at the same times in the northern Qinghai–Tibetan Plateau.
