Abstract
Growth anomaly of trees in some regions was detected under current episode of rapid warming. Thisraises a dilemma for temperature reconstructions by using tree-ring width which is believed to be themost important proxy on inter-annual temperature reconstruction during the past millenniums. Here weemployed the tree-ring d13C to reconstruct temperature variations for exploring their potential oncapturing signals of rapid warming, and to test how its difference with the tree-ring width basedreconstruction. In this study the mean MayeJuly temperature (TMeJ) was reconstructed over the pastcentury by tree-ring d13C of Chinese pine trees growing in the Nanwutai region. The explained varianceof the reconstruction was 43.3% (42.1% after adjusting... (More)
Growth anomaly of trees in some regions was detected under current episode of rapid warming. Thisraises a dilemma for temperature reconstructions by using tree-ring width which is believed to be themost important proxy on inter-annual temperature reconstruction during the past millenniums. Here weemployed the tree-ring d13C to reconstruct temperature variations for exploring their potential oncapturing signals of rapid warming, and to test how its difference with the tree-ring width basedreconstruction. In this study the mean MayeJuly temperature (TMeJ) was reconstructed over the pastcentury by tree-ring d13C of Chinese pine trees growing in the Nanwutai region. The explained varianceof the reconstruction was 43.3% (42.1% after adjusting the degrees of freedom). Compared to a ring-widthtemperature reconstruction (MayeJuly) from the same site, the tree-ring d13C-based temperaturereconstruction offered two distinct advantages: 1) it captured a wider range of temperature variability,i.e., at least MayeJuly, even over a longer part of the year, JanuaryeSeptember; and 2) the reconstructionpreserved more low-frequency climate information than that of ring width did.The 20th century warming was well represented in the Nanwutai tree-ring d13C temperature reconstruction,which implied that stable carbon isotope of tree rings potentially represents temperaturevariations during historical episodes of rapid warming. A spatial correlation analysis showed that ourtemperature reconstruction represented climate variations over the entire Loess Plateau in north-centralChina. Significant positive correlations (p < 0.1) were found between the temperature reconstruction andENSO, as well as SSTs in the Pacific and Indian Oceans. The reconstruction showed the periodicities of22.78-, 4.16-, 3.45e3.97- and 2.04e2.83-year quasi-cycles at a 95% confidence level. Our results suggestedthat temperature variability in the Nanwutai region may be linked to Pacific and Indian Ocean SSTvariations and solar activity. (Less)
