Summary: This study systematically analyzed the trend of difference between satellite-based land surface temperature and station-based air temperature from 2003 to 2022. The results showed that during daytime of summer, the satellite-based temperature exhibited slower warming rate compared to the station-based temperature, which was attributed to recent Earth greening. However, during summer nighttime and winter daytime and nighttime, the satellite-based temperature showed faster warming rate.

Summary: Based on the latest homogenized surface temperature data for China, this study analyzed the trends of surface-air temperature differences (SATDs) and found significant seasonal and interdecadal fluctuations, as well as the influences of precipitation and precipitation type changes on SATDs. The results indicated a spatial distribution pattern of increasing SATDs in the northern regions of China compared to the southern regions.

Summary: In recent decades, the Adriatic Sea and its coastal region have experienced significant environmental changes aggravated by climate change. This study analyzed time series of sea surface and air temperature in the Croatian part of the Adriatic Sea, showing increasing trends with sudden variations observed in 1998 and 1992, particularly in the warmer months from March to August. The results could aid stakeholders and decision-makers in developing effective measures to mitigate the negative effects of climate change in the scattered environment of the Adriatic islands and coastal region.

Summary: Some of the largest climatic changes in the Arctic have been observed in Alaska and the surrounding marginal seas. In the past half century, Alaska has experienced a broad increase in near-surface air temperature, especially during winter, spring, and autumn. Precipitation has also increased and is strongly related to temperature-sea ice feedbacks.

Summary: During the second half of the twentieth century, the Antarctic Surface Air Temperature (SAT) trends showed fast warming over West Antarctica but mild cooling over East Antarctica. However, after 2000, the warming over the Antarctic Peninsula slowed down while the South Pole experienced fast warming. A study using the CMCA method found that the reversals in SAT trends before and after 2000 were mainly attributed to changes in atmospheric circulation and thermal advection patterns over Antarctica. The CMCA decomposition provided a better understanding of the long-term SAT trend and its reversal for different seasons.

Summary: The study addresses the issue of underestimated warming trends in global surface temperature datasets over the past 20 years. New datasets show that the warming trend in global surface temperature is statistically significant over the past century.

Summary: The nitrogen cycle plays a crucial role in aquatic ecosystems, including the subsurface. However, the diversity of nitrogen transformations in these environments is not well understood. This study investigated how nitrogen cycling microorganisms respond to different groundwater chemistries. The results showed that regardless of site-specific conditions, nitrogen cycling mechanisms were prevalent and highly redundant in groundwater communities. The study also revealed the presence of oxic-anoxic interfaces and potential synergistic interactions between microorganisms at these interfaces. The findings provide insights into cooperative relationships in groundwater communities and the complexity of metabolic mechanisms leading to nitrogen loss.

Summary: This study reveals a significant increase in the canopy layer urban heat island (CLUHI) and surface urban heat island (SUHI) in some regions of mainland China in recent years, which may have negative effects on humans and the environment.

Summary: This study focused on the estimation of instantaneous air temperature (T-a) from MODIS atmospheric profile products aboard Terra and Aqua satellites. The accuracy of T-a estimation varied depending on MODIS datasets, regions, elevation, and land cover types. The multiple linear regression model significantly improved the estimation accuracy by introducing auxiliary data.

Summary: The study showed that atmospheric circulation had a minor impact on annual mean temperature trends in most areas, but had a significant effect on seasonal and monthly temperature trends. Removing the effect of circulation changes resulted in residual trends with a smoother annual cycle, which aligned better with model trends from CMIP5.

Summary: Microclimate temperature variability plays a crucial role in terrestrial biodiversity and ecosystem functions. A study in northern Europe found significant differences in microclimate temperatures across various seasons and locations in boreal forests and tundra. The temperature variations in boreal forests were closely linked to water bodies, wetlands, and canopy cover, while in tundra, they were associated with elevation, topographic solar radiation, and snow cover.

Summary: This study reveals the impact of abiotic and biotic properties on the evolution of microbial sensor systems in deep Earth environments. The abundance of these systems is correlated with variations in dissolved organic carbon and microbial diversity. These results suggest that multiple environmental properties drive the evolution of sensor proteins and emphasize the need for further research to understand the drivers of microbial sensor evolution.

Summary: The subsurface, considered as a separate biosphere, is crucial to Earth systems and is connected to the surface biosphere through a thin layer of the Earth's crust. This review discusses the recent advancements in understanding the functional and genomic diversity of the subsurface biosphere, as well as the interactions between microbes and minerals for energy and carbon, and adaptations to extreme environments. It specifically focuses on deep subsurface studies in mines, laboratories, and boreholes, aiming to comprehend ecosystem functions holistically.

Summary: Studies have shown that marine heatwaves in the Arctic are comparable with other regions globally, and in recent decades, there has been a significant increase in their intensity, frequency, duration, and areal coverage. These changes are closely related to increasing surface air temperature and decreasing sea-ice concentration under the global warming environment.
