Summary: This study used ICESat and ICESat-2 altimetry data to investigate global water level changes for 22,008 lakes/reservoirs greater than 1 km2. The results showed that 77.56% of the lakes/reservoirs experienced rising water levels from 2003 to 2021. Globally, 78.84% of lakes exhibited a rising water level, while the proportion for reservoirs was only 56.01%. Large-scale rising water levels were detected in the Tibetan Plateau, the Mississippi River basin, and high-latitude regions of the Northern Hemisphere. The study also found a negative relationship between the percentage of water level rise and population density in global river basins and 11 hotspots. The findings suggest that natural processes contribute to the rising inland water levels, while human activities can balance the rise through reservoir regulation. The study highlights the underestimation of global water level rise by existing datasets and emphasizes the importance of including small lakes/reservoirs in studying global hydrological cycle and water resource management.

Summary: Mass loss from polar ice sheets is the main cause of current sea level changes, and also a major source of uncertainty in sea level projections. The spatial pattern of sea level change can deviate from the global mean due to gravitational, Earth rotational and deformational effects. Ice sheet simulations predict that the geometry of mass changes and the relative mass loss from each ice sheet will vary in the coming century, leading to spatiotemporal variations in global sea level changes. This study emphasizes the need to consider temporal variations in the geometry of ice mass changes and the relative timing of ice mass changes between the Greenland and Antarctic Ice Sheets in assessing future sea level hazard.

Summary: Microscopic resolution is crucial for studying the spatial structure and interactions of microbial communities. This study investigates the microbial interactions at the micron-scale in anammox consortia and reveals the significant role of biotic interactions in the assembly of anammox communities. The results suggest that there is no statistically significant symbiotic interaction between anammox bacteria and other heterotrophic populations, and the conservative metabolic cooperation among Brocadia species may be regulated by quorum sensing with secondary messenger c-di-GMP.

Summary: Historically, limited measurements hindered our understanding of atmospheric temperature. However, recent satellite observations have provided new insights into the fine structure of the upper troposphere and lower stratosphere, which are crucial components of the climate system. These observations reveal a significant warming of the atmosphere, with the tropical upper troposphere warming by 1 K in the first two decades of the 21st century. The warming extends into the lower stratosphere, creating a prominent hemispheric asymmetry in temperature trends and a potential change in stratospheric circulation.

Summary: This study investigates the integrated application of ICESat, ICESat-2, and CryoSat-2 missions to provide consecutive lake level series. The deviations between CryoSat-2 and ICESat-2 data range from -0.78 m to 0.13 m. The quality of the synthesized time series is evaluated, with an average R (2) of 0.84. CryoSat-2 has the potential of filling the gap between ICESat and ICESat-2, and the three altimeters can effectively integrate for monitoring lake water level changes in the past two decades.

Summary: Satellite laser altimetry is widely used for monitoring surface height changes in inland waters. However, the temporal resolution of constructing time series of water levels is limited. This paper focuses on synthesizing multi-orbit observations from ICESat-2 to densify and refine water level time series for large lakes. The approach has been validated and shown to provide an effective solution for densifying water level series and monitoring high-frequency variations in lakes.

Summary: Long-term, continuous, and real-time streamflow records are crucial for understanding and managing freshwater resources. However, a significant portion of global gauge records are discontinuous and lack real-time data. To fill in the gaps, river width observations from satellite imagery have been used to estimate daily discharge at over 2000 gauge locations worldwide. This method improves our ability to monitor and manage river resources.

Summary: This study introduces the LakeFlow algorithm, which uses river-lake mass conservation and observations from the SWOT satellite to estimate the river discharge of lake and reservoir inflows and outflows. The performance of LakeFlow is tested at three lakes using synthetic SWOT data, and modeled lateral inflow and lake evaporation data are included to further constrain the mass balance. The results show that LakeFlow produces promising discharge estimates (median Nash-Sutcliffe efficiency = 0.88, relative bias = 14%). LakeFlow can inform water resources management by providing global lake inflow and outflow estimates, highlighting the interconnectedness of rivers and lakes as a system.

Summary: In this study, the changes in water storage in the water-receiving area of the South-to-North Water Diversion Eastern Route Project (SNWDP-ER) were analyzed using the latest Gravity Recovery and Climate Experiment (GRACE) technology. The study found that the implementation of SNWDP-ER aided the recovery of surface water but had little effect on groundwater and terrestrial water storage. Human activity and climate change have accelerated the decline of groundwater, leading to a decrease in terrestrial water storage.

Summary: The composition of dissolved organic matter (DOM) in lakes is influenced by multiple environmental factors at a continental scale. The study conducted in China's 182 lakes revealed that land cover and societal development have a positive direct effect on the quantity of DOM in lakes. Climate, on the other hand, has both a warming effect on soil organic matter production and export, and an enhancing effect on in-lake transformation of DOM. Three indicators were proposed to assess the influence of biogeochemical drivers on lake DOM across different ecoclimatic zones.

Summary: Levees can reduce the perception of flood risks and promote floodplain urban expansion, but their effect has weakened and reversed since the late 1970s due to legislative regulations. The interplay between levee construction and floodplain development is poorly quantified, hindering objective assessment of human-water relations. A quantitative framework is developed to evaluate the link between floodplain urban expansion and levee construction, revealing a clear change in risk perception after levees are built and providing useful guidance for managing flood risks.

Summary: Lakes and reservoirs are important components of global landscapes, serving as crucial repositories of freshwater and playing a significant role in carbon cycling and climate change. Understanding the hydrological connectivity of global lakes is essential for various applications, including lake change attribution and modeling of discharge, sediment, and carbon. The introduction of the global Lake drainage Topology and Catchment database (Lake-TopoCat) provides detailed information on lake hydrography and facilitates the development of a globally coupled lake-river routing model. Lake-TopoCat contributes to a wide range of limnological studies and has the potential to improve our understanding of water quality, fish migration, fluvial-lacustrine connectivity, and terrestrial carbon fluxes.

Summary: By analyzing Landsat imagery, the authors found that recent changes in river regime are attributed to morphological dynamics, dam-induced widening, and hydrological signals. Morphological dynamics dominate in approximately 20% of global river area. Reservoir constructions in Asia and South America contribute to about 32% of river widening. The remaining hydrological signals show contrasting patterns, with prominent river widening in alpine and pan-Arctic regions and narrowing in the arid/semi-arid continental interiors, driven by varying trends in climate forcing, cryospheric response to warming, and human water management.

Summary: Glacier retreat in the Tibetan Plateau is resulting in changes to its water system as a result of climate change. The lack of direct high-mountain observations has hindered our understanding of recent glacier loss in the region and limits our ability to predict the future of this vital water resource. A study of the west Nyainqentanglha Range revealed that glacier area and volume have been decreasing over the past 44 years, with an acceleration in retreat rate and surface lowering, particularly after 2014.
