Summary: The study reveals multiple alpine-style glaciations in High-Mountain Asia over the past 425 thousand years, comparable in extent to those during the last glacial maximum. These glaciations vary across the region, especially between the westerly influenced northern HMA and the monsoonal-influenced southern HMA. The dominant 23-kyr periodicity in HMA glaciation is attributed to the critical role of precession in regulating summer temperature and precipitation.

Summary: This study established a 4,800-year record of sea surface temperature variability in the eastern Mediterranean Sea using mass spectrometry imaging of long-chain alkenones. The research found that the highest amplitude of decadal temperature variability occurred in the early stage of sapropel deposition during the Last Interglacial, while the subsequent reorganization of oceanographic conditions did not exceed the recent period of warming climate in terms of decadal variability.

Summary: The study presents a sequence stratigraphic interpretation of subsurface data in a Lower Carboniferous lagoon setting in the northern boundary zone of the Precaspian Basin. The proposed model enables the reconstruction of relative sea-level history and refines the understanding of geological evolution and eustatic changes in the Caspi region during the Lower Carboniferous. The article highlights the formation of semicircular carbonate mounds in the Devonian period that enclosed a lagoon opening towards the Caspi Sea, emphasizing the significance of sea-level changes and sediment distribution within the lagoon.

Summary: Like many coastlines around the world, the Korean Peninsula experienced higher sea levels during the last interglacial. However, the geological record of this highstand differs between the eastern and western coasts. The tectonically active east coast has uplifted marine terraces, while the stable west coast has tidal flats and rias. This study reviewed existing data on sea levels during the last interglacial on both coasts of the Korean Peninsula and found that vertical movement has affected the elevations on the east coast, while the west coast has likely remained relatively stable.

Summary: The study fills the knowledge gap in Northwest Europe regarding Saalian Stage pollen records by correlating them with marine isotope substage level and presenting a multi-proxy supported river evolution model. The similarities between MIS 7 and MIS 5 pollen data from the same area indicate homotaxis, and suggest similarities in vegetation dynamics and climate variability between Southern and Northwest Europe during MIS 7.

Summary: The study revises the existing stratigraphic records in central and eastern Fennoscandia, revealing a more complete and extended palaeoenvironmental history than previously thought. The findings suggest the presence of birch forest tundra during certain warm intervals, challenging the previous assumption of boreal pine forests in the region. Additional research is needed to further explore the warm periods and sedimentary records during the Middle Weichselian in the studied area.

Summary: The sedimentary studies from the Marinoan deposits in South China provide a basis for establishing a sequence stratigraphic framework that includes two complete glacial cycles. These cycles demonstrate a pattern of ice-advance and ice-retreat successions, with corresponding changes in sedimentary facies and lithofacies association. The dynamic co-evolution of sedimentary environments, paleoclimate, and sea level during the Marinoan glaciation is indicated by this sequence stratigraphic framework.

Summary: Initially, terrestrial evidence was used to divide the Quaternary time, but has since been replaced by marine oxygen isotope stratigraphy. This shift has revealed global-scale changes in ice volume, but also highlighted the asynchronous nature of glacial records worldwide, leading to challenges in global correlation.

Summary: This study quantitatively assessed the relative utility of moraine crest and moraine slope sampling, finding that the spatial distribution of good boulders is effectively random, and landform stability has a greater influence on exposure age distributions than individual boulder characteristics. Postdepositional stability is strongly influenced by sedimentology, with differences between landforms potentially more significant than differences at the intra-landform scale.

Summary: This review of 157 studies on radiometric dating of glacial deposits in the Mediterranean reveals a greater complexity in the timing of Pleistocene glaciation than previously recognized. Evidence from various dating methods suggests that glaciers existed throughout the Late Pleistocene and even extended into the Middle Pleistocene in the region. Glacial activity in the Mediterranean mountains shaped the landscape significantly, and the deglaciation trend has continued into the Holocene with some small glaciers remaining today.

Summary: This study examines the annual balance of eight alpine glaciers from 1961 to 2018 and finds that the glaciers have experienced a negative balance, with a more significant decrease in balance from 1991 to 2018. By improving the calculation method and considering May-September temperatures, the study accurately predicts the annual balance of the glaciers. The research also reveals that temperatures in the Alps have already increased by approximately 3 degrees Celsius since 1880, indicating a rapid shrinkage of the glaciers if temperatures continue to rise.

Summary: This study investigates the glacial history and landscape evolution of the highest mountains in Wales, Y Glyderau and Yr Wyddfa, through the analysis of Be-10 and Al-26 exposure ages. The results suggest that the last Welsh Ice Cap did not cover the summits of Y Glyderau at the global Last Glacial Maximum (LGM), and instead the summits stood as nunataks. However, evidence shows that the summits were overridden by ice earlier in the last glacial cycle. The study also reveals a transition from ice cap to alpine-style glaciation as the ice cap rapidly thinned between 20-16 ka.

Summary: This study presents a glacial geomorphological analysis of three valleys on Mt. Mavrovouni in Greece, and uses cosmogenic Cl-36 dating to determine surface exposure ages of iron-rich ophiolite glacial and periglacial boulders. The results reveal the presence of distinct glacial and periglacial units, and provide support for the last glaciers on this massif forming during the Last Glacial Maximum. The study also demonstrates the validity of Cl-36 dating for iron-rich samples.

Summary: By analyzing lake sediment deposits from the Ioannina basin in NW Greece, this study examines millennial-scale climate instability in southern Europe during Marine Isotope Stage 6 (MIS 6) around 185-130 ka. The data reveals warm/wet and cool/dry intervals associated with Asian Monsoon events and North Atlantic interstadials. The presence of high-amplitude oscillations in diatom species assemblages suggests sensitivity to environmental thresholds during this period of frequent and persistent climate instability.
