Summary: This study investigates the Last Glacial Maximum (LGM) and the early retreat glacial phases in the Stura Valley of the Maritime Alps through the combination of geomorphologic surveys, glacial modelling, and 10Be exposure ages of boulders on moraines. The research reveals a consistent glacial response in the Maritime Alps to climatic forcing, with minimal variation in the mass balance of glaciers. The study also confirms the synchronicity of LGM recessional standstills or readvances in the Southern Alps.

Summary: This study evaluates glacial landforms preserved within the former LGM Rhine glacier and the eastern lobes of the LGM Reuss glacier system to understand LGM glacier dynamics. Through geomorphological mapping and new dating techniques, it is determined that the Rhine and Reuss glaciers reached their LGM maximum positions around 26-22 ka and 25/24 +/- 2 ka respectively. The glaciers showed subsequent oscillations, with late LGM readvances occurring after 20.6 +/- 1.7 ka and 20.8 +/- 1.3 ka for the Rhine and Reuss glaciers. The results provide valuable insights into the glacial history of the Alpine forelands.

Summary: We present a new glacier chronology of the Ticino-Toce glacier in the Southern Alps, reconstructing the timing and extent of its Last Glacial Maximum advance with detailed landform relationships and surface exposure dating. The study reveals that the glacier remained relatively stable with only minor oscillations over a period of approximately 5000 years, and the Verbano piedmont lobe was larger than previously thought. Additionally, the research suggests synchronized glacier advances across the Western Alps, except for the southwestern massifs.

Summary: The study examines the glaciation period in Central Asia, particularly the Mongolian Altai region, and finds that the glaciers reached their maximum phases around 35,440 years ago. Deglaciation began as early as 18,810 years ago and was mostly completed by 16,040 years ago. This research suggests that an additional climatic factor may have played a role in the rapid deglaciation around 18,800-16,000 years ago.

Summary: Proxy records indicate significant variability in climatic and environmental conditions across the Southern Hemisphere prior to the global last glacial maximum. This complexity suggests a different development pattern in the Southern Hemisphere compared to the North. Temperature and precipitation patterns show that local factors played a significant role in driving moisture availability.

Summary: This study presents geomorphological and geochronological reconstructions of the glacial and deglacial landforms in the southernmost part of Patagonia during the last glacial period. Through dating the moraines and paleo lakes, the study reveals the asynchrony of ice advances and different patterns of ice retreat between neighboring lobes, which may be attributed to the interaction between topography and precipitation from the southern westerly wind belt.

Summary: This study reports 20 Be-10 exposure ages from glacial erratics and bedrock on the west coast of British Columbia, Canada, contributing to the existing chronologies of Cordilleran Ice Sheet retreat along approximately 600 km of coastal North America. The data show that the western ice limit reached the present coast by 18-16 ka then slowed its retreat for around 4,000 years until 14-13 ka. The initial retreat is attributed to destabilization and grounding line retreat caused by rising sea level and/or ocean warming in the northern Pacific. Despite increasing temperatures, the subsequent stability of the ice sheet at the present coastal margin is likely due to the transition from marine to terrestrial margins.

Summary: The study applied a limited-area nested ice sheet model to investigate the last deglacial retreat of the West Antarctic Ice Sheet in the Amundsen Sea Embayment. The model simulations suggest a broadly similar response to ocean forcing in both central and eastern ASE, with an initial rapid phase of thinning followed by a slower phase to the modern configuration. The model-data mismatch could potentially be improved by considering regional variations in mantle viscosity, sea-surface heights, and basal sliding properties across the continental shelf.

Summary: Mountain glacier records provide important constraints on climate variability during the last glacial cycle. A new study in New Zealand reveals the role of climate in driving regional ice volume decline during marine isotope stages 3-2, with close spacing and good preservation of moraines from 19-17 ka supporting this finding. Onset of warming after 17.2 ka is consistent with evidence for a sustained southward shift in the southern westerly winds, promoting deglaciation.

Summary: The study in Bartang valley of northwestern Pamir utilizes cosmogenic Be-10 exposure ages to establish the timing and locations of glacial activities during the Middle Pleistocene, and highlights the instability of glacial sediments through catastrophic mega debris flows occurring after glacial retreat, with remobilized sediments providing valuable age constraints on glacial histories. The developed Gaussian separation algorithm allows for regional comparison of glacial chronologies, providing a summary of Middle and early Late Pleistocene glacial cycles in western High-Mountain Asia.

Summary: This study reconstructs the age and glacial activity of Mount Taibai during the Last Glacial Maximum (LGM). The results indicate a significant decrease in glacial coverage and equilibrium-line altitude (ELA) during the LGM, as well as a reduction in precipitation compared to the present. Temperature decrease is identified as the primary driver of glacial formation during the LGM on Mount Taibai.

Summary: Reconstructing the glacial history of Anvers-Hugo Trough on the western Antarctic Peninsula, this study provides insights into the past advance and retreat of the Antarctic Peninsula Ice Sheet. The research reveals that the ice sheet reached its maximum extent around 23-19 thousand years ago and had retreated to the middle shelf by 15.7 thousand years ago. The retreat rates varied across different sections of the continental shelf, with faster retreat observed from the outer to middle shelf compared to the middle to inner shelf.

Summary: The study reveals a detailed chronology of the Last Glacial Maximum expansions of the Rio Corcovado glacier in northern Patagonia, showing that the glacier's expansion was coeval with global Last Glacial Maximum and climatic signals, but out of phase with local summer insolation intensity. Additionally, it is observed that local ice sheet deglaciation occurred 1-2 ka earlier than other regions.

Summary: This study reconstructs the extent and timing of past glaciations in the northern Velebit Mt. in Croatia using geomorphological and sedimentological evidence, as well as cosmogenic 36Cl surface exposure dating. The empirical reconstruction suggests that the glaciers likely reached their maximum extent before the global Last Glacial Maximum, correlating with Marine Isotope Stage 5-4. The best-fit simulation indicates a cooling of 8 degrees C and a 10% reduction in precipitation for glaciers of this size to form, although uniform changes in climatological parameters do not completely match all ice margins mapped.

Summary: This study presents a comprehensive inventory of denudation rates and ratios along the East Australian passive continental margin. Denudation rates are influenced by topography, with higher rates associated with higher rainfall. Additionally, low Al-26/Be-10 ratios are hypothesized to be linked to hydrological variability.

Summary: Large earthquakes have a significant impact on the topographic evolution of active mountain ranges. In this study, the researchers analyzed in-situ Be-10 concentrations in fluvial sediments to understand the post-earthquake denudation rates of the Conway River catchment in New Zealand. The results showed higher erosion rates at the rangefront compared to the river outlet, and the overall erosion rates were consistent with previous studies.

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 shows that the uplift of the Tian Shan range altered the regional climate in Central Asia during Cenozoic aridification. The growth of the mountain range changed the wind patterns and led to increased aridity in the Issyk-Kul basin, resulting in the formation of lakes. Changes in the river systems and tectonic activities also played a role in the formation of lakes.
