Adequate knowledge of climatic change over the Tibetan Plateau (TP) with an average elevation of more than 4000 m above sea level (a.s.l.) has been insufficient for a long time owing to the lack of sufficient observational data. In the present study, monthly surface air temperature data were collect

Abstract
We have identified the northern Tibetan Plateau as having experienced the most significant warming of any region in the entire plateau domain since 1961. Warming in the northern plateau violates the previously suggested elevation dependency of warming trends. Further analysis shows that the increase in surface air temperature in summer has played a primary role in the rapid increase of the annual mean air temperature in the northern Tibetan Plateau since the midβ1980s. In addition, the summer air temperature is correlated with ozone in the region, a result which is statistically significant. This correlation seems to have a relationship with solar radiation and ozone depletion ratios. Further discussion shows that the most significant warming in the northern plateau may be related to radiative and dynamical heating that are results of pronounced stratospheric ozone depletion.

## Abstract Although global warming over the past century has been confirmed, the response of different regions to it is still uncertain. We developed a treeβring width chronology based on treeβring samples from juniper trees from the Xiqing Mountains in the northeast Tibetan Plateau, the central h
Dissolved inorganic carbon isotope (Ο 13 C DIC ) is an important tool to reveal the carbon cycle in lake systems. However, there are only few studies focusing on the spatial variation of Ο 13 C DIC of closed lakes. Here we analyze the characteristics of Ο 13 C DIC of 24 sampled lakes (mainly closed
