Summary: A statistical relationship has been identified at a global scale between the sensitivity of precipitation and runoff to temperature change, which is used to constrain future runoff sensitivity estimates. While this relationship slightly reduces the uncertainty range of future runoff sensitivities, it significantly raises the expected global runoff sensitivity to background global warming.

Summary: Surface albedo plays a crucial role in the energy and water cycles, and the parameterizations of surface albedo greatly impact the simulation of radiation partition in climate models. In this study, in-situ measurements and MODIS albedo product were used to evaluate the simulated surface albedo by 24 Global Climate Models. The results showed varying monthly albedo among models, with the ensemble mean closer to in-situ measurements. Some models exhibited significant biases in annual surface albedo cycle, and snow albedo parameterization schemes varied in fitting snow albedo attenuation over time in all models.

Summary: Spatial patterns of lake evaporation increase due to global warming are closely linked to regional hydroclimate drying effects. Future lake evaporation is projected to increase globally, with amplification in areas with drier hydroclimates and dampening in areas with wetter hydroclimates. Coupled changes in lake evaporation and hydroclimate have significant implications for regional water balance and can exacerbate water scarcity and flood risks.

Summary: This study evaluated the point-scale simulations of CLM5 across different forest structures and solar angles at two climatically different locations, revealing that canopy structural shading of the snow surface exerted a primary control on Land Surface Albedo (LSA). The diurnal patterns of measured LSA showed strong effects of both azimuth and zenith angles, neither of which were adequately represented in simulations. In sparse forest environments, LSA were overestimated by up to 66%.

Summary: This study systematically investigates and compares the simulated seasonal precipitation response in the Sahel among CMIP5 ESMs and its observational counterpart. It finds that CMIP5 models can reasonably capture the seasonal evolution of Sahel precipitation and soil moisture, although with some biases. The coupling of an ESM to a DGVM is critical in generating reasonable land-atmosphere feedback and examining future ecological and climatic changes over the Sahel.

Summary: The study improves the Two-Resistance Mechanism (TRM) attribution method to analyze the urban-rural contrast of heat stress. The method can diagnose any heat stress index related to temperature and humidity. The summertime urban-rural contrast of Simplified Wet Bulb Globe Temperature (SWBGT) is primarily caused by evapotranspiration and heat storage release in urban areas. The differences in aerodynamic features in urban-rural areas play both positive and negative roles.

Summary: This study attempts to quantify the potential impacts of two global warming levels (1.5℃ and 2.0℃) on extreme temperature indices across China. The findings suggest that China will experience more frequent and intense high temperature events, while the number of icing days and frost days is projected to decrease, particularly in the west of China. Limiting global warming to 1.5℃ is beneficial in reducing extreme temperature risks. The research also indicates that the most extreme temperature indices are expected to increase disproportionately more during the final 0.5℃ of warming than during the first 1.5℃, with the largest incremental changes found in the southwest.

Summary: This study uses CloudSat-CALIPSO satellite data to evaluate the modeled cloud fraction in CMIP5 models during a recent historical period. The comparison reveals that most CMIP5 models do not account for precipitating and convective core hydrometeors, leading to significant underestimation of cloud fraction compared to satellite-retrieved data. The underestimation is particularly pronounced in certain regions and altitudes where precipitating ice and convective core hydrometeors play a major role.

Summary: This study characterized simulated extreme and moderate El Nino events and analyzed historical teleconnections on climate extremes in South America. It also addressed projected changes in these teleconnections under global warming context using 10 CMIP5 GCMs from three experiments. Results show that extreme El Nino events are projected to increase in occurrence, with similar spatial impacts to moderate events but potentially higher intensity in some regions and seasons.

Summary: Soil moisture-atmosphere coupling induces non-linear warming via the 'warmer climate - drier soil' feedback, exerting an accelerating effect on global warming and extreme high temperatures. The projection shows that SA-driven warming will exceed 0.5°C over extratropical landmasses by the end of the 21st Century, increasing the likelihood of extreme high temperatures.

Summary: Occupying 7% of the world's forest area, plantation forests have been increasing globally and are considered a natural climate solution. However, whether plantation forests face the same fate as natural forests under changing climate conditions remains uncertain. A study comparing the vitality and resilience of large plantation patches and natural forest patches in China over the past 20 years found that while plantation forests in humid areas showed consistent sustainability with natural forests, those in drier environments exhibited lower vitality and faced challenges in expanding.

Summary: Changes in vegetation have significant impacts on water availability. Observations show that global water availability has increased due to vegetation changes, mitigating the recent decline in water availability. However, in water-limited or high-elevation regions, increased vegetation may have adverse effects on water resources.

Summary: Ecoenzymatic stoichiometry is proposed as a method to estimate microbial nutrient limitations, but the critical thresholds for identifying these limitations are still unclear. In this study, we developed methods to quantify the critical thresholds for carbon, nitrogen, and phosphorus limitations in microbial communities. We also provided new insights into the relationships between ecoenzymatic activities and distinguished six initial limitation scenarios based on regression intercepts. Our results suggest that phosphorus and nitrogen availabilities are the most important limitations on microbial production and metabolism in terrestrial soils and freshwater sediments. This perspective provides a foundational framework for understanding and quantifying microbial nutrient limitations in studies of terrestrial carbon cycling and microbial ecology.

Summary: Nitrogen loss due to soil denitrification in global natural ecosystems is overestimated by almost two times in current earth system models, highlighting the need for improvement. The study quantifies the loss using an isotope-benchmarking method and produces a global map of natural soil N-15 abundance. The overestimation of denitrification in models has implications for the assessment of CO2 mitigation and plant growth responses.

Summary: Atmospheric methane concentrations are increasing, and recent studies using a process-based model show higher methane emissions from wetlands since 2007. The substantial increase in methane emissions in 2020 and 2021 contributed to record-high growth rates of atmospheric methane. Wetland methane emissions, as an uncertain feedback to climate change, amplify atmospheric methane concentrations. The findings emphasize the importance of continuous monitoring and observations of global wetland methane fluxes to understand emerging trends, variability, and underlying drivers.

Summary: To control the atmospheric methane concentration for the Paris Agreement and Global Methane Pledge, it is crucial to understand the global methane budget, especially considering the dangerous high growth rate of atmospheric methane concentration in the past three years (2020-2022). Interdisciplinary research can provide valuable insights into methane budget and contribute to effective mitigation strategies, as demonstrated in this Special Issue on Methane emissions, sinks, and mitigation.

Summary: Precipitation is a crucial component of the global water cycle that strongly affects societal activities and terrestrial ecosystems. To improve the accuracy of precipitation emulation, we have developed a data-calibrated precipitation emulator (PREMU) that can estimate and represent precipitation simulated by different Earth system models (ESMs) under different emission scenarios. The emulator shows good performance in predicting observed precipitation and simulating future scenarios.
