Summary: Through satellite observations, it was found that the all-sky instantaneous radiative forcing increased by 0.53 ± 0.11 W/m² from 2003 to 2018, mainly due to the rising concentrations of greenhouse gases and reductions in aerosol emissions. These results highlight the distinct fingerprints of anthropogenic activity in Earth's changing energy budget.

Summary: In a 42-day microcosm experiment, we found that nanoplastics have significant effects on soil microbial community structure, nitrogen removal processes, greenhouse gas emissions, and ecosystem multifunctionality. Positively charged nanoplastics have a stronger impact on soil microbial community structure and functions. Nanoplastics at environmentally realistic concentration inhibit soil denitrification but enhance anammox. Nanoplastics decrease soil N2O flux, while increasing CO2 and CH4 emissions. Nanoplastics can increase ecosystem multifunctionality but also increase greenhouse gas emissions.

Summary: Wheat is a crucial crop for global food security, however, boosting wheat yield on current cropping areas may not be enough to meet future global food demands. Climate warming has allowed wheat to be cultivated in previously uncultivated areas at higher latitudes. However, growing wheat in these regions presents several challenges, including the release of greenhouse gases. It is crucial to conduct research and develop wheat production techniques that minimize environmental damage in high latitude areas.

Summary: This study demonstrates a lack of correlation between the variations in dust accumulation rate (DAR) on the southern Chinese Loess Plateau (CLP) and aridification over the past 130,000 years. Instead, it suggests that loess DAR variation is more likely determined by wet-dry cycles and the availability of loose sediment through fluvial and glacial processes.

Summary: The study found that during the Early Pleistocene, the intensity of the East Asian Summer Monsoon strengthened, with a generally stronger intensity from 2.2-2.06 million years ago, relatively weak intensity from 2.06-1.97 million years ago, and gradual intensification thereafter. The zonal thermal gradient in the Equatorial Pacific may have played an important role in driving the evolution of the EASM over a tectonic timescale during the Early Pleistocene.

Summary: This study reconstructs the vegetation and precipitation changes during the Younger Dryas event in northeastern China based on pollen data. The results suggest a shift from steppe to forest and wetter conditions in Northeast China, with colder temperatures and increased precipitation during the Younger Dryas. The study also finds significant differences in moisture conditions between northern and southern Northeast China, with increased precipitation in the north as a response to the strengthening of the Okhotsk High.

Summary: During the Quaternary, the closure and opening of Hudson Bay have had significant impacts on local and global climates. Our study using the LOVECLIM1.3 model shows that the closure of Hudson Bay can strengthen the Atlantic Meridional Overturning Circulation, leading to a warming in the Northern Hemisphere and cooling in the Southern Hemisphere. This closure also affects surface properties and wind-driven sea ice export, resulting in cooling in specific regions.

Summary: This study compiled paleoenvironmental reconstructions and used numerical simulations to investigate the evolution and drivers of the East Asian Summer Monsoon (EASM) and South Asian Summer Monsoon (SASM) during the late Miocene. The results showed that the late Miocene climate underwent an overall drying trend in northern China but a wetting trend in the South China Sea and surrounding areas. The modeling results suggested that a decline in atmospheric CO2 may have been a key driver of the evolution of the EASM and SASM during the late Miocene.

Summary: Through the study of soil models and climate simulations, we found that precipitation and temperature were the main climate factors influencing the population expansion in Eurasia from the Late Pleistocene to the Early Holocene. Changes in population size in low latitude regions were mainly controlled by precipitation, while temperature played a dominant role in the middle-high latitude regions. These findings provide important clues for understanding the human dispersal during the Late Pleistocene.

Summary: Documenting the spatiotemporal patterns of the Holocene Optimum (HO) at the East Asian monsoon (EAM) margin is crucial for understanding monsoon climate dynamics. The timing of the onset of the HO at the EAM margin is debated, but the uncertainties in different proxy records have hindered progress. To overcome these uncertainties, the study compared moisture variations from different proxy records and found a delay in the HO initiation in the core EAM region compared to the monsoon margin. The study also suggests that the monsoon margin may be sensitive to different forcing factors than the core monsoon region.

Summary: Climate model simulations suggest that changes in global sea level modify atmospheric and oceanic circulation. The recent increase in global mean sea-level rise presents a challenge in assessing its climate impacts, but previous warmer periods with higher sea levels provide a unique opportunity to investigate climate effects. Simulations show that a rise in sea level reorganizes atmospheric and oceanic circulations, and even a slight increase in global mean sea level can cause substantial adjustments in the global climate.

Summary: Plate tectonics play a vital role in regulating atmospheric CO2 concentration over geological timescales. Current research on tectonic CO2 dynamics requires the development of models that include four modules: simulating carbon processes, calculating CO2 fluxes, reconstructing carbon cycling within tectonic scenarios, and comparing with atmospheric CO2 history data. The primary technical challenge lies in simulating the complex carbon dynamics across different scales in time and space.

Summary: We present a 12-Myr long South Asian summer monsoon (SASM) record based on the strontium and neodymium isotopic composition of detrital components at IODP Exp. 359 Site U1467. Provenance analysis shows that dust enriched in eNd from northeastern Africa and the Arabian Peninsula was transported to the study site by monsoonal and Shamal winds during the summer monsoon season. We propose a two-step weakening of the SASM wind since approximately 12 million years ago based on the eNd record. Climate modeling results support this observation, indicating that the SASM evolution was mainly controlled by changes in the gradient between the Mascarene High and the Indian Low, caused by growth of interhemispheric ice sheets since the Middle Miocene.

Summary: Volcanic arc degassing plays a significant role in atmospheric CO2 levels and paleoclimate changes. The Neo-Tethyan decarbonation subduction is believed to have influenced Cenozoic climate changes, and this study provides further evidence by analyzing subduction scenarios and paleoclimate parameters. The findings suggest a causal link between subduction processes, carbon-rich sediments subducting, and global warming.

Summary: Landforms on the Martian surface provide valuable insights into past surface processes, but the modern hydroclimatic conditions on Mars are still not well understood. This study reports the discovery of various surface features on salt-rich dunes in southern Utopia Planitia, suggesting the involvement of saline water from thawed frost/snow as the most likely cause. The findings shed light on the more humid conditions of the modern Martian climate and have important implications for future exploration missions searching for signs of extant life.

Summary: This study reconstructed annual precipitation of the Asian summer monsoon (ASM) and Australian summer monsoon (AusSM) from 1588 to 2013 (1588 to 1999) to examine the relationship between ENSO and monsoon and how it has changed. The results showed that the ENSO-monsoon relationship has become stronger since 1850, indicating the influence of anthropogenic climate warming. Climate model projections further suggested that global warming can strengthen the ENSO-monsoon association and synchronize ASM and AusSM variations.

Summary: This study reconstructed a 400-year streamflow time series for the Irrawaddy River in Myanmar using tree-ring cellulose oxygen isotopes (d18O) and examined the changes in hydrological extremes before and after global warming. The study found an increase in extreme drought events in the region, with the frequency of droughts significantly increasing since the 1850s. The persistent drought conditions during 2000-2017 were unprecedented in the last 400 years, and this increase in drought events is attributed to the weakening of the Indian Summer Monsoon and rising temperatures.

Summary: The southwestern Huanghuai Plain, located in the transitional climate zone between southern and northern China, played a significant role in the origin of civilization in Central China. Through phytolith analysis on sediment samples from Zhangwangzhuang, this study reveals the early occurrence of rice-millet mixed farming in the area. The proportion of rice fluctuated over time, which might be attributed to the abundant water resources. Additionally, the expansion of millet cultivation in the region could be influenced by climate change. This study provides important insights into the subsistence strategy and adaptation to climate change in the north-south transitional zone of China.

Summary: Widespread and frequent droughts have affected most parts of Europe over recent years. The onset of the drying trend in southern Europe occurred around the 1850s, and anthropogenic warming has enhanced the strength of land-atmosphere coupling and exacerbated the widespread drying trend since then. This persistent drying trend in southern Europe is likely the result of warming and close coupling between soil moisture and atmospheric temperature.
