Summary: In this study, the response of key climate quantities to changes in greenhouse gases or aerosols is investigated using six global climate models. The results show that ocean temperature changes become evident after a couple of months, while rapid reductions in precipitation occur instantly and stabilize within a few days. The magnitude of precipitation response gradually increases for carbon dioxide and sulfate, and switches from negative to positive after 2 years for carbon dioxide. Rapid cloud adjustments are typically established within the first 24 hours, and the geographical pattern of cloud change is present after the first year. Overall, our work highlights the similarity of major processes and responses simulated by current global models, indicating the robustness of simulated responses to historical and future forcing.

Summary: Spray technology is an effective method for improving indoor environments in poultry houses. This study investigates the effects and control mechanisms of spray processes on ammonia, particulate matters, and aerosol bacterial compositions in two different intensive enclosed poultry houses. The results show that spray treatments with tap water, EM microbial agent, or glutaraldehyde-decamethonium bromide solution can significantly reduce ammonia levels. Spray processes also decrease particulate matter content and alter aerosol bacterial compositions mildly. The study also suggests that fecal transmission is the main source of aerosol bacteria, with spray processes having a relatively small impact on fecal contribution. These findings contribute to optimizing breeding environments and enhancing disease prevention in poultry farming.

Summary: Over the past century, pastoral systems have experienced significant changes in management to meet the livelihood needs of alpine communities. However, global warming has resulted in a serious decline in the ecological status of pastoral systems in the western alpine region. Using remote-sensing products and process-based models, we evaluated changes in pasture dynamics and projected the impacts of climate change on alpine pastures. The findings suggest that the growing season will lengthen, water stress may limit productivity, earlier grazing onset could enhance productivity, higher livestock densities may increase biomass regrowth, and carbon sequestration potential could decrease due to limited water availability and warming.

Summary: This study examines the fast response of East Asian summer precipitation to COVID-19-induced aerosol emission reductions using the CESM2.2 model. The emission reductions decreased aerosol optical depth and cloud cover over northern China in June 2020. This led to a warmer troposphere, strengthening the land-sea thermal contrast and anomalous southerly winds. As a result, there was increased precipitation over the Yangtze River basin (YRB) during June 2020. The emission reductions over China caused stronger convective precipitation but weaker larger-scale precipitation compared to emission reductions outside China. Additionally, sea surface temperature anomalies in 2020 also played an important role in increasing precipitation over the YRB, contributing about 42.8%.

Summary: As high temperature and heatwave pose great threats to human survival, it is important to understand the spatial and temporal changes of temperature. Traditional methods, such as meteorological stations, only provide limited information. To address this, a joint spatio-temporal method using remote sensing data was proposed to obtain dense temperature mapping. Additionally, a heatwave risk model based on population and temperature data was developed to evaluate the risk in different areas. The effectiveness of these methods has been verified through accuracy evaluations and case studies in Zhejiang Province.

Summary: This study characterized the impacts of transboundary haze from peatland fires in Indonesia and local emission sources on PM2.5 in Hat Yai, a city in southern Thailand, during 2019-2020. By measuring various chemical components of PM2.5 samples, the study identified both local and regional emission sources. The results showed that the increase in PM2.5 and chemical component concentrations during the transboundary haze period was mainly influenced by aerosols from open biomass burning in Indonesia. The study also found that secondary organic carbons and biomass burning were the dominant sources during this period.

Summary: Despite a decrease in fine particulate matter (PM2.5) concentrations, ozone pollution in China has increased in frequency and persistence. Open crop straw burning (OCSB) activities release a significant amount of trace gases, contributing to elevated ozone concentrations. This study demonstrates the impact of OCSB emissions on ground-level ozone and associated health effects in China. Reductions in OCSB emissions due to implementation of straw burning bans lead to a decrease in annual averaged ozone levels and result in health benefits in east and central China.

Summary: The researchers used an integrated approach to predict fatality rates caused by benzene emitted from floating-roof tanks. The results showed that atmospheric temperature, wind speed, failure diameter, and emission height have positive effects on the dispersion of the toxic benzene vapor cloud. Social risks estimation indicated that over 1600 fatalities should be expected under the worst-case scenarios. It is necessary to provide an emergency response plan in the studied industry in both autumn and winter due to low wind speed.

Summary: The accumulation of heavy metals in natural rubber latex has implications for the health of the plant and the integrity of the rubber. A study in Malaysia examined the concentration of heavy metals in latex collected from different areas over a year and found that high levels of heavy metals acted as an excellent compatibilizer in blends with improved properties. This discovery suggests that natural rubber can help reduce heavy metal accumulation in the environment and improve the performance of rubber blends.

Summary: Solar radiation management (SRM) reduces the earth's temperature by reflecting more sunlight back to space, but its impacts on hydro-climatic extremes in Southeast Asia are unclear. This study simulates the effects of SRM on the Kelantan River Basin in Malaysia and finds that it can lead to cooling effects, reducing annual and monthly precipitation during the flooding season. It also decreases the number of days with heavy precipitation and intensity of maximum daily precipitation, resulting in reduced high flows. However, the driest months experience comparable decreases in precipitation and streamflow under SRM impacts.

Summary: A study was conducted in Brunei Bay, northwest Borneo, to understand the causes of low dissolved oxygen. The study found that hypoxia was widespread in the bottom waters during the monsoonal dry season, but less extensive during the wet season. The hypoxia in the dry season was primarily caused by riverine nutrient input and subsequent decomposition, while the wet season had less hypoxia due to reduced coastal primary production, intrusion of oxygen-rich water from the South China Sea, and increased advection of phytoplankton biomass out of the bay through horizontal flushing.

Summary: Reliable precipitation information is crucial for scientific and operational applications. Open-access gridded precipitation products (OGPPs) are important sources due to their continuous spatiotemporal coverage. This study proposes a methodology to comprehensively compare the accuracies and stabilities of ten different OGPPs, particularly in mountainous basins. The results show high accuracy but unstable performance of all OGPPs, with multi-source fusion-type products offering better stability and accuracy. Multi-source weighted-ensemble precipitation and climate prediction center morphing method products exhibit the best comprehensive performance.

Summary: This study, based on reanalysis data from 1980 to 2019, reveals that the relationship between autumn sea ice concentration in the Barents-Kara Seas (BKSIC) and subsequent winter North Atlantic Oscillation (NAO) underwent an interdecadal weakening in the early 1990s. The weakening can be attributed to the decrease in the interannual variability of BKSIC, which leads to a discrepancy in the tropospheric warming. In the former period (1980-1993), the decrease in autumn BKSIC enhances tropospheric warming and weakens the circumpolar westerly, resulting in a negative NAO phase. However, in the latter period (1994-2019), the smaller interannual variability of BKSIC weakens its influence on the tropospheric temperature, diluting the relationship with the subsequent winter NAO.
