Summary: Global climate change has a profound impact on vegetation growth patterns. However, regional climate characteristics tend to weaken the disparities in vegetation responses observed in large-scale studies. Additionally, different vegetation types exhibit distinct reactions to climate variability, making it challenging to detect and attribute changes in vegetation growth. This study used the normalized difference vegetation index (NDVI) dataset to investigate the spatiotemporal distribution and dynamic characteristics of climate change effects on vegetation growth from 2000 to 2020. The findings revealed a continuous greening trend, with precipitation identified as the dominant climatic factor influencing this trend. Continued warming, however, has led to a slowdown in vegetation growth. Solar radiation was also found to correspond to the vegetation trend. These findings highlight the nonlinearity of long-term vegetation growth trends with climate variation and provide valuable insights into forecasting vegetation responses to future climate change.

Summary: This study used GLASS data to examine the trends of leaf area index (LAI) in the Yan Mountains over the last four decades. The results showed a persistent increase in LAI (greening) in the study area, which was influenced by anthropogenic activities. The LAI increase varied with elevation and was negatively correlated with land surface temperature and soil moisture, but positively correlated with precipitation and air temperature. The study also found a time-lag effect between hydrothermal factors and LAI changes. These findings provide insights into vegetation adaptation to land surface and climatic hydrothermal conditions in mountain regions, and can be used for ecological protection policies.

Summary: This study aimed to investigate whether the accuracy of LAI estimation can be improved by involving leaf chlorophyll content (LCC) information. The sensitivities of seven PROSAIL simulated Sentinel-2 bands to LAI and LCC were studied, and related vegetation indices were constructed. LAI and LCC estimation models were then generated using these sensitive vegetation indices. The results showed that introducing LCC information improved the accuracy of LAI estimation, with the functional equation of LCC performing the best.

Summary: Research shows that grazing on the grasslands of the Qinghai-Tibet Plateau has positive effects on the Normalized Difference Vegetation Index (NDVI) at the beginning and end of the growing season, but negative effects in the middle. The seasonality of grazing effects alters the NDVI-biomass relationship, impacting the assessment of climate change impacts. Furthermore, the seasonality of grazing effects should be considered an important factor in analyzing grassland response to warming climates.

Summary: This study examines the influence of urbanization on local atmospheric moisture under global warming in China. The findings indicate significant declines in atmospheric humidity, forming an 'Urban Dry Island' (UDI). The observed UDI is caused by global warming, urban heat island effect, and reduction in local evapotranspiration and water vapor supplies. The magnitude and frequency of UDI are more pronounced in humid regions compared to arid regions due to differences in background climate and vegetation characteristics. Restoring the evapotranspiration power of urban ecosystems is crucial in mitigating the negative effects of UDI and UHI.

Summary: The hydrological effects of afforestation in different basins across China were explored using hydrologic observations and remote sensing data. It was found that afforestation and reduced precipitation contributed to runoff reduction in cold and dry basins, while afforestation and drying climate induced a significant decrease in runoff in a semi-arid basin. Wet basins showed insignificant changes in total runoff, but an increase in baseflow during dry seasons. The study highlights the long-term variable effects of forest expansion and local climatic variability on basin hydrology.

Summary: The COVID-19 lockdown in Wuhan in early 2020 led to a reduction in human activities, which in turn altered the urban heat island effect. The study compared the intensity of the heat island effect during different stages of the epidemic period with the baseline period. It found that the heat island effect decreased during the epidemic period, with the largest decrease observed during the strictest lockdown period. This study provides important observational evidence of human-induced control on urban climate.

Summary: Agriculture, as a widespread land use activity in urban surroundings, has the potential to alter urban climate. This study investigated the impacts of rural croplands on urban heat island effects in three major urban agglomerations in China. The results showed that urban lands warm the air temperature substantially, but the warming is partially cancelled by rural croplands. The impacts of croplands on urban climate depend strongly on the concurrent urban heat island effects.

Summary: The Himalaya Plateau, including Nepal, is experiencing a greening trend, which has significant implications for ecosystem services. This comprehensive study reveals that the community forestry program, forest area changes, and soil moisture availability are the major drivers of the greening trend. Before 2004, soil moisture and forest area changes were the primary factors, while the community forestry program and forest expansion became dominant afterwards. Winter precipitation, incoming solar radiation, and pre-monsoon soil moisture significantly influenced interannual vegetation dynamics. Projections based on Earth System Models suggest that Nepal's greening trend will continue throughout the 21st century. This study provides important national-level information for forest management policies and nature-based solutions to address climate change and increasing demands for ecosystem services in Nepal.

Summary: This study improved a distributed regional land surface model to evaluate the impacts of climate and land use changes on soil erosion and sediment yield in the Mississippi River Basin (MRB) over the past century. The results showed that despite no significant increase in annual precipitation and runoff, sediment yield significantly increased during 1980-2018, mainly driven by intensified extreme precipitation. Land use change played a critical role in determining sediment yield in the early 20th century, while climate variability became the dominant driver in recent decades. Extreme climate is increasingly affecting soil erosion and sedimentation, emphasizing the need to revisit existing Best Management Practices for water quality in the MRB.

Summary: 'Urban Dry (Wet) Islands' (UDI/UWI) phenomenon has an impact on ecosystems and human well-being, but the causes are not fully understood. This study quantifies UDI and UWI using global observations and finds close linkages with local evapotranspiration, global warming, and 'Urban Heat Islands'. UDI is most pronounced in humid vegetated regions, while UWI is found in arid regions or climates with dry summers. The study suggests that evapotranspiration can be used as a single variable to explain emerging urban environmental changes and advocates for restoring nature's evapotranspiration power as effective solutions to mitigate the negative environmental effects of urbanization.
