Summary: The study reconstructs hydroclimatic changes in northeastern North America over the past millennium, revealing spatially divergent patterns during the Medieval Climate Anomaly and Little Ice Age. The wetter conditions in southern peatlands and drier conditions in northern and continental sites during these periods suggest complex hydroclimatic patterns. The spatial variability of hydroclimate change during the Little Ice Age may be related to local permafrost aggradation and similarities with dry periods during the Medieval Climate Anomaly.

Summary: This study investigates the influence of the East Asian monsoon (EAM) and El Nino-Southern Oscillation (ENSO) on seawater carbonate chemistry in the tropical Pacific. The results show a correlation between the intensity of the East Asian summer monsoon and variations in surface-water carbonate chemistry. Rapid changes in carbonate chemistry are linked to ENSO-like states and the East Asian winter monsoon. These findings suggest that tropical conditions play a crucial role in glacial-interglacial atmospheric CO2 concentration changes.

Summary: A high-resolution sediment record from Lake Tuofengling in Northeast China reveals the climate variations in the region since the last glacial period. The study shows that the lake level decreased slightly during the late Holocene and increased during the late Holocene. These changes are closely related to the variations in the effective moisture of the East Asian summer monsoon.

Summary: Changes in convective activity and hydroclimate in Northeastern Kalimantan during different climatic periods are influenced by the southward shift of the tropical rain belt and the Intertropical Convergence Zone. The weakening of tropical convection during Heinrich Stadials and the Younger Dryas is associated with enhanced seasonality of rainfall and an extended dry season. Increased sediment discharge and intensification of convective activity during the early to mid-Holocene are linked to high Northern Hemisphere insolation, elevated atmospheric pCO(2) levels, and global warming. Our reconstructions highlight the high spatial variability of Kalimantan hydroclimate on millennial to glacial-interglacial timescales when compared to regional terrestrial and marine records.

Summary: This study reconstructs sea surface temperature (SST) and seawater oxygen isotope (δ O-18(sw)) in the central Andaman Sea over the past 26,000 years to investigate the driving mechanism of millennial-scale climate changes in the tropical Indian Ocean. The results show that the changes in SST and δ O-18(sw) during the last deglaciation are associated with the Asian monsoon system, which is influenced by North Atlantic climate changes. The strengthening of the East Asian winter monsoon and the weakening of the Indian summer monsoon play a crucial role in the millennial-scale hydroclimate changes in the tropical Indian Ocean.

Summary: Through the investigation of archaeological data from the Ladakh region, it is found that there have been significant changes in climatic conditions from 19.6 to 6.1 thousand years ago, with a transition from westerly circulation to monsoon dominance. This change is closely related to the position of the ITCZ influenced by solar radiation and the variability of atmospheric circulation. The study also suggests the occurrence of an early wet phase of two-fold H1 events during a period of westerly dominance. The mid-Holocene period from 7.5 to 6.1 thousand years ago was characterized by westerly regain, coinciding with decreasing insolation, weakening monsoon, and enhanced El Nin & SIM;o activities.

Summary: Research reveals that the conversion of forests from deciduous to evergreen broadleaf in the subtropical zone of southern China is closely related to climate change. The increase in evergreen plant components was triggered by postglacial temperature increase, while a complete transition to evergreen forest ecosystems required specific climate conditions.

Summary: This study reconstructs late Quaternary vegetation changes in the hydrographic basin of Parnaiba, Northeast Brazil using palynology and geochemical proxies. The results suggest that these changes were primarily influenced by austral insolation and hydrological disturbances. Additionally, past climate change events may have contributed to the high biodiversity of the region through ecological forest corridors.

Summary: Thermocline conditions in the tropical western Pacific play a critical role in global climate evolution. However, the long-term changes in thermocline hydrology in the subtropical northwestern Pacific and its connection to the tropical Pacific are still unclear. Based on planktonic foraminiferal Mg/Ca and delta(18O), this study reconstructed the temperature and salinity of thermocline water in the subtropical northwestern Pacific since the last deglaciation. The results showed a close relationship between thermocline hydrology and changing conditions in the tropical western Pacific, indicating a significant role of the ENSO-like process in regulating thermocline dynamics.

Summary: The South Atlantic subtropical dipole (SASD) has a significant impact on South American rainfall, with meltwater forcing being the main driver of variability. Lower frequency energy for the SASD, particularly during cold events, comes from meltwater discharge. Changes in the latitudinal gradient of South Atlantic sea surface temperature and Northward heat transport are attributed to the meltwater discharge, leading to significant rainfall changes in Northeastern Brazil.

Summary: The study on the glacial history of Asgardfonna Ice Cap in Svalbard using lake sediment cores and geophysical data from Femmilsjoen revealed that larger Svalbard ice caps are highly sensitive to climate changes and likely melted completely during the Holocene Thermal Maximum. This information can provide important constraints for future ice-cap simulations.

Summary: The study reconstructed hydrological dynamics over the past 700 years in Northeast Asia using samples from the Hani peatland in the Changbai Mountains, revealing wetter conditions from 1300-1700 AD, dry conditions from 1700-1850 AD, and wet conditions from 1850-2018 AD. The driving mechanisms for these hydrological variations were identified as La Nina-like conditions, volcanic aerosol effects, and El Nino-like conditions. The results suggest that solar activity and sunspot cycles may control the hydrological dynamics in Northeast Asia on a decadal-centennial scale.
