Summary: This comprehensive review explores the sources, characteristics, and climate impacts of light-absorbing aerosols (LAAs) over the Tibetan Plateau. The Tibetan Plateau, also known as the Third Pole, is home to a large number of glaciers and acts as a water tower for Asia. Exogenous pollutants, particularly LAAs, have led to increased warming and accelerated glacial melting in the region. These impacts extend beyond the Tibetan Plateau, affecting the hydrological cycle and leading to environmental and social problems in South Asia, East Asia, and even the Northern Hemisphere.

Summary: Most glaciers on the Tibetan Plateau are retreating, leading to significant environmental and ecological consequences. Factors such as decreased precipitation and increased light-absorbing particles are contributing to reduced glacier accumulation. A recent study investigated the effects of extremely low precipitation caused by La Nina, and found that it resulted in decreased snow accumulation and higher LAP concentrations on glacier surfaces. This phenomenon is expected to accelerate glacier melt in the region and should be considered in future research.

Summary: Seeds exhibit substantial plasticity of germination in response to environmental variability. The study shows that closely related species share similar light plasticity of germination behavior. Different aspects of germination plasticity are related to specific traits and local environment, with habitats having sufficient soil moisture inducing greater plasticity of germination in response to light availability. These findings simplify our understanding of germination, facilitate exploration of germination patterns, and enhance our understanding of species diversity maintenance, adaptation, and evolution from the perspective of germination.

Summary: Using a hemispherical directional reflectance factor instrument, this study collected spectral data on dirty snow containing black carbon, mineral dust, and ash to investigate their impact on snow reflectance properties. The findings revealed that the perturbation of snow reflectance caused by these light-absorbing impurities (LAIs) is nonlinear, with a declining reduction rate as snow contamination increases. The study also identified the specific effects of each LAI on snow reflectance at different wavelength ranges. The results of this study provide valuable insights for snow albedo simulations and improve the accuracy of LAIs' remote sensing retrieval algorithms.

Summary: The Tibetan Plateau vortices are the major precipitation-producing weather systems on the plateau, with a more significant impact in the warm season but also important in certain regions during the cold season. The interannual variation of vortices and associated precipitation is mainly determined by the number of vortices, while the heating anomaly caused by the Tibetan Plateau thermodynamic effect is also a significant factor.

Summary: The U-235/U-238 atom ratio in surface soils of the Tibetan Plateau (TP) ranged from 0.007122 to 0.007615, indicating anthropogenic contamination of U-235. The contamination was more pronounced in the northeast and southwest sectors of the TP. The observed U-235 contamination may have originated from nuclear activities in surrounding areas, such as the north Gobi Desert and South Asia, and was transported to the TP by prevailing winds crossing the Himalayas.

Summary: South Asian biomass burning is crucial for the heavy springtime air pollution over the Tibetan Plateau, contributing significantly to aerosol components. The transboundary transmissions of these aerosols are regulated by large-scale westerly winds and regional mountain-valley winds. In addition to worsening air quality, aerosols from South Asian biomass burning also lead to temperature decrease and precipitation reduction, posing a threat to the fragile ecosystem of the Tibetan Plateau during springtime.

Summary: This study analyzed the changes in river discharge and sea ice in the Kara and Laptev Seas from 1979 to 2019. The results showed that there were significant increases in discharge and heat from the rivers, while the sea ice concentration decreased. The changes in discharge and riverine heat mainly affected the initial and final stages of sea-ice melting. The cumulative riverine heat from May to September had a large impact on the sea ice changes in the Kara and Laptev Seas. However, the contribution of river discharge changes to the reduction in sea ice concentration was limited at annual scales.

Summary: The analysis of uranium isotope ratio is important for distinguishing between natural and anthropogenic sources of uranium. In the northeastern Tibetan Plateau, the ratio of 235U/238U in riverine suspended particulate matter is found to be similar to that of natural uranium, while surface soil shows a slightly higher ratio, potentially due to enrichment from atmospheric nuclear tests. This study confirms that the northeastern Tibetan Plateau remains relatively pristine with minimal biogeochemical disturbances from human activities.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
