“…On the basis of ice cores data from the TP [Yao et al, 2000;Tian et al, 2006;Kang et al, 2007], warming in high elevation regions appears much more rapid than in low elevations. However, the mechanisms for this contrast are not clear.…”

[1] Trend magnitudes of 11 indices of temperature extremes at 71 stations with elevations above 2000 m a.s.l. in the eastern and central Tibetan Plateau (TP) during 1961 -2005 are examined. Most trends in extremes are consistent with general warming in the TP. There are no significant correlations between elevation and trend magnitude of temperature extremes with the exception of TXn (coldest day temperature) and TX10 (cold day frequency). Thus an enhanced sensitivity of temperature extremes at higher elevations in the eastern and central TP is not apparent in the context of recent warming in this region. Although previous work showed a correlation between elevation and mean temperature trends in the TP, this analysis fails to substantiate this relationship for extremes. Analysis of trend magnitudes by topographic type and degree of urbanization show both factors to have a strong influence in this dataset, which overrides that of elevation.

“…The magnitude of warming in alpine regions is predicted to be much greater than the global average (IPCC, 2007). The warming amplitude increases with increasing altitude on this Plateau (Liu and Chen 2000;Yao et al, 2000). Field experiments have analysed the potential effects of warming on the alpine soils on the Tibetan Plateau (Fu et al, 2012;Li et al, 2011;Rui et al, 2011;Xu et al, 2010a;Yu et al, 2014).…”

A B S T R A C TAlpine ecosystems at high altitudes and latitudes are notably sensitive to climatic warming and the Tibetan Plateau is a widely distributed alpine ecosystem. The magnitude of climatic warming on the Tibetan Plateau is expected to be considerably greater than the global average. However, a synthesis of the experimental warming soil carbon and nitrogen data is still lacking and whether forest soils are more sensitive to warming than grassland soils remains unclear. In this study, we used a meta-analysis approach to synthesise 196 observations from 25 published studies on the Tibetan Plateau. Warming significantly increased microbial biomass carbon (MBC) by 14.3% (95% CI: 2.9-24.6%), microbial biomass nitrogen (MBN) by 20.1% (95% CI: 2.0-45.1%), net nitrogen mineralization by 49.2% (95% CI: 38.1-62.3%) and net nitrification by 56.0% (95% CI: 51.4-66.1%), but did not significantly affect soil carbon (95% CI: À13.9 to 2.7%) or nitrogen (95% CI: À12.4 to 2.6%). The mean annual air temperature was negatively correlated with the warming effects on MBC and MBN. Grasslands exhibited significant MBC and MBN responses to warming. Specifically, soil microbial biomass was more responsive to warming in colder environments. Moreover, forest soils are not always more sensitive to warming than grassland soils as previous studies have suggested. These findings indicate that clarifying the effect of warming on alpine soils need consider ecosystem types and their local climate.

“…The ecosystem in regions with higher elevation such as Tibetan Plateau, similar to the poles area with high latitudes, is more sensitive to global change (Sun and Zheng 1998;Feng et al 1998;Zheng and Li 1999;Liu and Chen 2000;Yao et al 2000). It could be used as a detection tool or a monitor for global warming (Giorgi et al 1997;Liu and Chen 2000).…”

The main portion of Tibetan Plateau has experienced statistically significant warming over the past 50 years, especially in cold seasons. This paper aims to identify and characterize the dynamics of inland lakes that located in the hinterland of Tibetan Plateau responding to climate change. We compared satellite imageries in late 1970s and early 1990s with recent to inventory and track changes in lakes after three decades of rising temperatures in the region. It showed warm and dry trend in climate with significant accelerated increasing annual mean temperature over the last 30 years, however, decreasing periodically annual precipitation and no obvious trend in potential evapotranspiration during the same period. Our analysis indicated widespread declines in inland lake's abundance and area in the whole origin of the Yellow River and southeastern origin of the Yangtze River. In contrast, the western and northern origin of the Yangtze River revealed completely reverse change. The regional lake surface area decreased by 11,499 ha or 1.72% from the late 1970s to the early 1990s, and increased by 6,866 ha or 1.04% from the early 1990s to 2004. Shrinking inland lakes may become a common feature in the discontinuous permafrost regions as a consequence of warming climate and thawing permafrost. Furthermore, obvious expanding were found in continuous permafrost regions due to climate warming and glacier retreating. The results may provide information for the scientific recognition of the responding events to the climate change recorded by the inland lakes.
