“…Using the ring widths and stable carbon isotope ratios (δ 13 C) of Qilian juniper from the upper treeline, Liu et al (2007) reconstructed the December-April temperature in the Qilian Mountains with a 3-year resolution over the past 1000 years. Zhu et al (2008), using ring width data from Qilian juniper at the upper treeline, reconstructed mean September-to-April temperatures for the Wulan area, Qinghai Province, since AD 1000. The two reconstructions showed the occurrences of generally low temperatures during AD 1600-1800 and the abrupt warming toward the end of past millennia.…”

Abstract.A 1343-year tree-ring chronology was developed from Qilian junipers in the central Qilian Mountains of the northeastern Tibetan Plateau (TP), China. The climatic implications of this chronology were investigated using simple correlation, partial correlation and response function analyses. The chronology was significantly positively correlated with temperature variables prior to and during the growing season, especially with monthly minimum temperature. Minimum temperature anomalies from January to August since AD 670 were then reconstructed based on the treering chronology. The reconstruction explained 58 % of the variance in the instrumental temperature records during the calibration period and captured the variation patterns in minimum temperature at the annual to centennial timescales over the past millennium. The most recent 50 years were the warmest period, while 1690-1880 was the coldest period since AD 670. Comparisons with other temperature series from neighbouring regions and for the Northern Hemisphere as a whole supported the validity of our reconstruction and suggested that it provided a good regional representation of temperature change in the northeastern Tibetan Plateau. The results of wavelet analysis showed the occurrence of significant quasi-periodic patterns at a number of recurring periods (2-4, 40-50, and 90-170 years), which were consistent with those associated with El Niño-Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO) and solar activity. The comparison between the reconstructed temperature and the index of tropical volcanic radiative forcing indicated that some cold events recorded by tree rings may be due to the impact of tropical volcanic eruptions.

“…Tree rings, as an annually resolved proxy record, have been increasingly used to reconstruct past climate changes on the TP (e.g., Bräuning and Mantwill 2004;Gou et al 2008;Liang and Eckstein 2009;Liang et al 2008;Liu et al 2007;Liu et al 2006;Shao et al 2005;Shi et al 2010;Wang et al 2009;Yang et al 2009;Yin et al 2008;Zhang et al 2003;Zhu et al 2008). For example, Liu et al (2007) reconstructed winter temperature variations since AD 1000 for the middle Qilian Mountains using Sabina przewalskii.…”

“…In China, much effort has been spent in the last few decades to reconstruct regional proxy temperature series with lengths of 500-2000 years from historical documents [8][9][10][11][12][13][14][15], tree rings [16,17], stalagmites [18], ice cores [19], and lake sediments [20][21][22][23][24]. Uncertainty analysis of these regional reconstructions indicates that warming during the 10-14th centuries in some regions might be comparable in magnitude to the warming of the last few decades of the 20th century that was unprecedented in the past 500 years [25].…”

Using 24 proxy temperature series, the rates of temperature change in China are analyzed at the 30-to 100-year scales for the past 2000 years and at the 10-year scale for the past 500 years. The results show that, at the 100-year scale, the warming rate for the whole of China in the 20th century was only 0.6±1.6°C/100 a (interval at the 95% confidence level, which is used hereafter), while the peak warming rate for the period from the Little Ice Age (LIA) to the 20th century reached 1.1±1.2°C/100 a, which was the greatest in the past 500 years and probably the past 2000 years. At the 30-year scale, warming in the 20th century was quite notable, but the peak rate was still less than rates for previous periods, such as the rapid warming from the LIA to the 20th century and from the 270s-290s to 300s-320s. At the 10-year scale, the warming in the late 20th century was very evident, but it might not be unusual in the context of warming over the past 500 years. The exact timing, duration and magnitude of the warming peaks varied from region to region at all scales. The peak rates of the 100-year scale warming in the AD 180s-350s in northeastern China as well as those in the 260s-410s and 500s-660s in Tibet were all greater than those from the mid-19th to 20th century. Meanwhile, the rates of the most rapid cooling at scales of 30 to 100 years in the LIA were prominent, but they were also not unprecedented in the last 2000 years. At the 10-year scale, for the whole of China, the most rapid decadal cooling in the 20th century was from the 1940s to 1950s with a rate of 0.3±0.6°C/10 a, which was similar to rates for periods before the 20th century. For all regions, the rates of most rapid cooling in the 20th century were all less than those for previous periods. China, past 2000 years, rates of temperature changeCitation:
