Summary: Lake surface water temperature (LSWT) is a critical physical property and indicator of climate change in the aquatic ecosystem. This study presents a comprehensive dataset of daily LSWT for 160 lakes across the Tibetan Plateau, combining satellite-based observation and modeling. The dataset reveals a significant increase in annual LSWT from 1978 to 2017, with a higher warming rate in winter than in summer.

Summary: This study explores the relationship between lakes and Tibetan antelopes in the vulnerable Tibetan Plateau. It found that areas with larger lakes and flatter terrain tend to have a higher population of Tibetan antelopes. Additionally, vegetation cover and plant diversity are higher near the lake compared to farther away. These findings suggest that lakes offer Tibetan antelopes a richer food supply and reduced predation risk. The study provides new perspectives for understanding the cross-ecosystem impacts of climate change.

Summary: This study reveals the seasonality and timescale of the Tibetan warming amplification and points out that winter exhibits the strongest warming amplification. Additionally, the simulation results show that the amplification of warming in the Tibetan Plateau region is relatively weak, which is attributed to the underestimation of warming in this area by the models. By conducting the attribution study, it is found that the stronger warming response to human influence on the Tibetan Plateau is the direct cause of the Tibetan warming amplification.

Summary: The rate of permafrost collapse is accelerating on the Tibetan Plateau, with the area of collapsed permafrost increasing by approximately a factor of 40 from 1969 to 2017, with 70% of the collapsed area forming since 2004. These widespread perturbations could trigger changes in local ecosystem state and amplify large-scale permafrost climate feedbacks.

Summary: This study investigated the environmental drivers of albedo in the Tibetan Plateau based on remotely sensed data, revealing the significant impacts of snow cover, vegetation index, and soil moisture on albedo changes in different seasons and spectral bands. The findings are expected to enhance the understanding of energy budget simulations over the Tibetan Plateau region in land surface models.

Summary: This study utilized multivariate data fusion and deep learning to analyze the structural changes in plant communities in alpine grasslands on the Tibetan Plateau. The results revealed an increase in the proportion of alpine meadows, a strengthening of dominant vegetation types, and variations in the driving factors depending on the vegetation type.

Summary: This study integrated the Optimal Land Degradation Index and spatial footprints to investigate changing trends and degradation risks on the Qinghai-Tibet Plateau. The results showed that land improvements were dominant, accounting for 18.83% of the plateau. High-risk degraded land covered an area of 0.55 million km2, while low-risk degraded land covered 0.78 million km2. The spatial distribution of high-risk degraded land varied gradually from scattered small areas to increasingly frequent connected patches.

Summary: The unique characteristics of land-air coupling and troposphere-stratosphere interaction over the Tibetan Plateau play a vital role in weather and climate on regional and global scales. However, gaps in our understanding still exist due to a lack of observations and model biases. To address these obstacles, a 10-year research program called LASTPIC was launched in 2014, focusing on TP land-air coupled processes, TP's influence on global climate, and reanalysis and model development.

Summary: These lakes have undergone significant changes in recent years, with later freeze-up and break-up dates. The changes in ice cover duration showed spatial heterogeneity. Air temperature changes had the greatest influence on ice phenology, followed by solar radiation. Weakened wind power in the northeastern part of the plateau contributed to delayed break-up and extended ice cover. Water balance changes, affected by lake size and salinity, intensified ice phenology changes in some lakes while moderating or reversing changes in others. The spatial inconsistency of changes in multiple climatic factors was the main reason for the heterogeneity of lake ice phenology changes. This study provides important insights into the effects of climate change and lake properties on lake ice phenology.

Summary: The carbon and nitrogen cycling on the Qinghai-Tibetan Plateau has been influenced by atmospheric warming, cryosphere thaw, and intensified human activities. Despite the complexity of these changes, they largely offset each other. The plateau is predicted to continue functioning as a net carbon sink in the future, despite severe permafrost degradation, while nitrogen stocks are expected to remain relatively stable.

Summary: This study analyzed the environmental characteristics of high ice-content permafrost sites on the Qinghai-Tibetan Plateau. The results showed that temperature, precipitation, soil moisture, geomorphology, and soil composition are important factors influencing the distribution of high ice-content permafrost. The study provides a foundation for understanding the environmental changes in these areas and modeling the distribution of ground ice.

Summary: Exploring climate change and teleconnection on the Tibetan Plateau is crucial for understanding global climate change. However, further research is needed due to limited observation data and inadequate consideration of multiple atmospheric circulation indices. In this study, a climate dataset for 1901-2017 was used to analyze precipitation and temperature, and multivariate wavelet coherence was employed to investigate the combined effects of various circulation indices. The results showed spatial and temporal variations in climate, with a general trend of increasing precipitation and temperature. Single and combined circulation indices had significant impacts on climate change, highlighting the importance of considering multiple factors.

Summary: The increasing severity of climate change poses a significant challenge to the livelihoods of smallholders. This study examines how smallholders adapt to climate change under government interventions and provides recommendations for governments to better promote smallholder adaptation. The results show that smallholders mainly adopt four adaptation strategies while governments assist them through subsidies, training, credit, insurance, improved varieties, infrastructure development, and cooperatives. The study highlights the importance of natural capital indicators and government interventions in facilitating smallholder adaptation.

Summary: During the extreme warming period, surface temperatures in glacial regions of the Tibetan Plateau have increased faster than non-glacial areas, and the duration and intensity of glacier surface heatwaves have significantly increased. These changes may pose potential threats to the sustainability of glacier water resources and increase the risk of glacier related hazards.
