Summary: The diurnal temperature range (DTR) has significantly decreased in many land areas as a consequence of global warming. This study investigates the spatial distribution and future projections of DTR variations on the Mongolian Plateau under different global warming levels. Precipitation and cloud cover were found to be the main factors influencing DTR changes. This study enhances the understanding of climate change in the region and provides a valuable reference for similar studies.

Summary: Daily precipitation extremes are projected to intensify with increasing moisture under global warming following the Clausius-Clapeyron (CC) relationship at about 7%/?C. However, this increase is not uniformly distributed. By leveraging theory and observations of precipitation probability distribution, we can improve intermodel agreement and interpret projected changes more accurately. As a result, risk due to regional enhancement of precipitation scale increase by dynamical effects must be included in vulnerability assessment even if locations are imprecise.

Summary: Mean surface temperature is projected to rise significantly in India, leading to increased hot temperature extremes and decreased cold temperature extremes in all climate zones. Rainfall indices also show an increase in high precipitation events, although with large uncertainties in the projections. These changes are expected to have far-reaching impacts on the social and economic statuses of the respective climate zones, highlighting the need for responsive climate change adaptation policies at national and state levels.

Summary: This study quantifies the impacts of different global warming levels on severe droughts in six countries (China, Brazil, Egypt, Ethiopia, Ghana and India). The findings show that current climate change mitigation pledges would lead to severe drought in all studied countries, while meeting the long-term temperature goal of the Paris Agreement would greatly reduce drought risks for these countries.

Summary: The suppressed late-20th Century warming seen in CMIP6 is not only caused by a stronger aerosol forcing, but also by weaker greenhouse gas forcing and differences in climate sensitivity between CMIP5 and CMIP6 ensemble. This leads to stronger aerosol cooling over 1960-1990 and stronger greenhouse gas induced warming from 1990, returning the warming post-2000 toward the observed level.

Summary: This study investigates the changes of two atmospheric feedbacks, the amplifying zonal wind feedback and the damping heat flux feedback, in El Nino/Southern Oscillation (ENSO) under global warming conditions. The findings show that the amplifying zonal wind feedback over the western equatorial Pacific becomes significantly stronger, while the heat flux damping feedback over the eastern and central equatorial Pacific increases in most models. The strengthening of these two feedbacks can be explained by the stronger warming in the eastern region, which shifts the Pacific Walker Circulation and increases convection over the central equatorial Pacific. Additionally, the study finds a relationship between the change in ENSO amplitude and the change in ENSO atmospheric feedback.

Summary: This article introduces a methodology for improving mid-term power system resilience at transmission substations in flood-affected areas through a combination of hardening strategies and quantitative metrics. The methodology considers flood forecasts, location of electrical equipment, and resilience planning strategies, and utilizes a mixed-integer linear programming formulation for optimal hardening. Ultimately, the choice of appropriate mitigation strategies can optimize resilience metrics and cost indicators across various scenarios.

Summary: Irrigation can both cool and warm air temperature depending on the balance between daytime cooling and nighttime warming. Evaporative cooling and reduced solar radiation during the daytime can lower air temperature, while the increased atmospheric water vapor at night can enhance the local greenhouse effect and increase nighttime temperature. It is important to consider sub-daily processes when assessing the impact of irrigation on daily air temperature and temperature-related socioeconomic phenomena.

Summary: The representation of groundwater dynamics in land surface models and their roles in global precipitation variations have been studied recently. The incorporation of the groundwater component in climate models has led to higher soil moisture and diverse precipitation changes. However, the effects of groundwater on large-scale atmospheric energy transport, a fundamental atmospheric variable regulating Earth's climate, have not been thoroughly explored.

Summary: Arctic Amplification (AA), characterized by greater warming in the Arctic compared to the global mean, exhibits a seasonal dependence. Models predict that the annual maximum AA will shift from autumn to winter over the 21st century, but there is considerable uncertainty in the exact timing and magnitude of this shift. Model differences dominate the total uncertainty, while emission scenarios have a negligible impact on AA projections.

Summary: Groundwater resources are connected with various systems such as social, economic, ecological, and Earth systems. A new framing called groundwater-connected systems is introduced to better understand the complexity of these connections in terms of data collection, scientific investigations, governance, and education. This framing allows for a holistic approach to studying the interactions between groundwater and social-ecological systems, emphasizing the importance of integrating multiple perspectives and goals to achieve groundwater sustainability.

Summary: The importance of ecosystem services in water resources management has led to a focus on environmental-flows requirements for moving waters. However, current management practices often overlook the contribution of groundwater and fail to consider its importance in environmental flows. This study presents two methods for estimating groundwater environmental flow contributions, one based on groundwater and the other on surface water. The methods were tested in British Columbia, Canada and showed comparable results, suggesting their potential applicability in data-scarce, hydrologically complex landscapes globally.

Summary: Deforestation affects the exchange of heat, moisture, and momentum between the Earth's surface and the atmosphere, leading to significant impacts on surface energy balance and water budget. However, simulations from different models show diverse changes in surface heat fluxes due to deforestation. This study investigates the factors causing these variations and uses the NCAR Community Land Model to explore the impacts of tropical deforestation on surface heat fluxes. Results demonstrate that changes in surface heat fluxes are related to the initial conditions of flux partitioning over deforested areas. Deforestation tends to reduce surface heat fluxes when evaporative fractions are smaller, and decrease latent heat fluxes while increasing sensible heat fluxes when evaporative fractions are larger. Similar findings in the Land Use Model Intercomparison Project suggest that varying simulated flux partitioning conditions contribute to the diversity in surface heat flux changes among models.

Summary: Environmental change, especially water crises, is a crucial driver of human migration, particularly in vulnerable regions and low- and middle-income countries. However, the interconnected patterns between water-related events and migration are not yet fully understood. This study combines quantitative text-mining with qualitative thematic analysis to explore these patterns and identifies four major patterns of water-driven migration: water quantity variability, damaging water hazards, physical disturbances to water systems, and water pollution. Understanding the dynamics of water-migration requires considering the interconnections between water changes and migration patterns, investigating the interactions between different water variables and socioeconomic factors, developing an integrated water-migration database for early-warning signals, and implementing targeted water policies to enhance resilience in climate-vulnerable regions and populations.

Summary: Groundwater, although being one of the largest reservoirs of water on Earth, has small fluxes compared to its volume. Deep groundwater (>500 m) is only weakly and sporadically connected to the rest of the terrestrial water cycle, contributing <0.1% to global streamflow. However, it plays a significant role in the global chloride cycle, providing around 7% of the flux of chloride to the ocean.

Summary: In this study, the impacts of the Pacific-Japan (PJ) pattern on the summer temperature and heatwave characteristics in Taiwan were investigated using long-term station-based temperature and rainfall dataset. The results showed that during the positive phase of the PJ pattern, there was an island-wide increase in temperature in Taiwan, accompanied by an increase in the effective area and frequency of heatwave extremes. The adiabatic warming due to subsidence anomaly associated with the anticyclone over Taiwan was identified as the primary contributor to the surface warming.

Summary: Managing groundwater is difficult due to its underground existence. The GRACE tool provides an opportunity for monitoring groundwater storage, but linking scientific research to policymaking and groundwater practices is limited. This paper aims to improve the use of GRACE data for sustainable groundwater management through a Delphi survey collecting opinions from academic and non-academic communities. The survey reveals the potential and willingness of both communities to collaborate and suggests recommendations for better application of GRACE data.
