Summary: Geochemical data from seep carbonates in the South China Sea reveals three stages of methane seepage linked to the dissociation of biogenic methane hydrate, potentially accelerating global warming at glacial-interglacial transitions.

Summary: The study focuses on uncertainties in SST reconstructions and provides recommendations for reliable proxies and calibrations. LIG warming and cooling in the penultimate glacial maximum are compared, with reported uncertainties reflecting geographic variability and dating errors. Detailed interpretation of temperature records from small numbers of sites is not recommended, and comparisons with model simulations should focus on the regional average.

Summary: This paper describes the Quaternary evolution of Meiji Atoll in the southern South China Sea. The findings show how variations in sea surface temperature, eustatic sea level, and tectonics have influenced the development of the atoll. These findings have broader implications for understanding the Quaternary evolution of similar tropical carbonate atolls in the region.

Summary: Quaternary interglacial climates are often used as analogues for future responses of the Antarctic Ice Sheet to climate warming. Southern Ocean marine sediments provide an important paleoclimate archive. There are challenges in reconstructing SST in the Southern Ocean, but foraminifera assemblages and long-chain alkenones are considered the most reliable proxies for SST reconstructions in this region.

Summary: By combining rainfall proxy records with multi-model simulations, this study identifies dominant 23 ka rainfall cycle in northern China and 100 ka rainfall cycle in southern China and Southeast Asia. It is proposed that rainfall in the north is primarily driven by insolation, while rainfall in the south is largely forced by high-latitude ice sheets. This study provides new insights into the Asian hydroclimate conditions associated with high-low-latitude climate interactions.

Summary: Research suggests that global mean sea level (GMSL) during the last interglacial (LIG) period may have been higher than at present, with a 95% probability of peaking at least 1.2 meters higher than today and a very low likelihood (5% probability) of exceeding 5.3 meters. Uncertainties in the glacial isostatic adjustment (GIA) process and input models reduce precision and accuracy in estimating past GMSL, but findings indicate the potential for lower GMSL during the LIG period than previously assumed.

Summary: This study presents new marine pollen records from the southern South China Sea during the Last Glacial Maximum (LGM) and finds that the sites in front of the Sunda Shelf palaeo-rivers contain more Poaceae pollen and a smaller size fraction compared to the offshore site near North Borneo. Abundant lowland tree pollen with similar major taxa is also observed. These results suggest a longitudinal climate gradient with increasing aridity towards the interior of glacial Sundaland, supporting the hypothesis of a savanna corridor over the LGM Sundaland.

Summary: This study synthesized a 140 kyr stack (MT2022) of 95 stalagmite δ18O records from Southern China, which showed agreement with the variation of summer insolation and restored the variability of Asian Summer Monsoon (ASM). MT2022 was compared to other datasets and found to be consistent with SIOC19 and more suitable to represent the ASM evolution. Comparisons with three Greenland ice core timescales showed that MT2022 was consistent with NGRIP (GICC05) but differed from GRIP (ss09sea) and GISP2 (Meese-Sowers). The high degree of consistency between GICC05 and MT2022 validates their accuracy and suggests that MT2022 may serve as a new chronological reference for climatic events in the last glacial-interglacial cycle.

Summary: This study quantitatively reconstructs the tectonic and total subsidence history of the Xisha Islands in the South China Sea using paleo-water depth constraints. The results show that tectonic subsidence rates were influenced by magmatic intrusion and thermal cooling processes, while total subsidence rates had a significant impact on the formation of reef units.

Summary: This study investigates the interconnection between the southern South China Sea and Java Sea by simulating seasonal circulations and associated transports. The results show significant water exchanges between the two seas in winter and summer, with the direction of water transport correlating with changes in water temperature and salinity. The ROMS estimates peak water transports in May, attributed to the simulated anticyclonic eddy in the southern South China Sea.

Summary: China is a crucial region for studying the relationship between climate change and hominin evolution. Archaeological sites from the Early to Middle Pleistocene in China reveal that early human activities gradually shifted southward during multiple glacial-interglacial cycles, with frequent bidirectional movements between north and south during different periods.

Summary: The Last Interglacial is an important period for studying global warming scenarios and comparing proxy models. This study focuses on the sea surface temperature (SST) during this period and presents a record from the western tropical South Atlantic. The results show warmer temperatures during the Last Interglacial compared to pre-industrial and Holocene conditions. The study suggests that the positive anomaly in tropical SST can be explained by polar sea ice loss during this period.

Summary: According to the study, the Pearl River plays a more important role in transporting terrigenous sediments to the western South China Sea than the Red River, while the Mekong River may contribute more sediments to the region than the Sunda shelf and the Indonesian islands in the south. Geochemical ratios can be used to trace terrigenous sediment variations in the western South China Sea, indicating a close relationship with the East Asian monsoon evolution during the last 130,000 years of glacial-interglacial cycles.

Summary: Investigating the sedimentary architecture and evolution of sand-rich submarine fans in the Qiongdongnan Basin is crucial for understanding deep-water sedimentary processes and improving the success rate of hydrocarbon resource exploration. The study reveals the presence of five distinct deep-water depositional systems, including a unique sand-rich submarine fan, and provides valuable insights for offshore gas hydrate and shallow gas exploration in the basin.

Summary: In this study, paleoredox conditions in the Western Equatorial Atlantic (WEA) during the glacial-interglacial cycle were reconstructed using high-resolution REEs data and anomalies. The results indicate that the Parnaiba River is the main source of REEs in the western South Atlantic, and changes in the negative Ce-anomaly suggest a reduction in deep ocean oxygenation during the interglacial period. Additionally, the origin of positive Eu anomalies in the core is attributed to preferential retention by feldspars.
