Summary: The present study investigates the palaeogeographic evolution of the coastal Lihoura plain in central-eastern Greece during the Late Holocene. Through core drilling, sediment analysis, and geomorphological mapping, the study reveals that the plain was inundated by seawater during the Mid-Holocene and later transformed into a protected lagoonal environment due to the development of a limestone peninsula. A recent high energy marine inundation event was also recorded in the northern part of the plain. The study estimates the average rates of sea-level rise during certain time periods.

Summary: Studying the interactions between paleoecology and climate variations in semi-arid areas, such as the Songnen grasslands in northeastern China, provides insights into how future vegetation changes and hydrological variations may impact semi-arid ecosystems. This study presents a high resolution palaeoecological dataset covering the past 7300 years and reveals the dynamics of vegetation and water levels in the Dabusu peatlands. By comparing these features with regional climate change, the study suggests that East Asian Summer Monsoon circulations might be the main driving force controlling the regional paleovegetation dynamics and hydrological variations.

Summary: The study shows that the wetland evolution in the Sanjiang Plain has been significantly influenced by the East Asian summer monsoon circulation. A transition from a shallow-water lake to a wetland occurred around 4.5 ka BP, coinciding with a decline in the strength of the monsoon. The wetland development over the past 4.5 ka BP has been closely linked to variations in the East Asian summer monsoon.

Summary: The lakes of the coastal oasis in Larsemann Hills respond to changes in regional climate, influenced by ice-sheet dynamics, and eustatic variation. Sedimentary sequences from ice-free regions in Antarctica provide unique climate records. A lake's evolution reconstructed from sedimentary sequences shows that it transitioned from a proglacial lake dammed by ice-sheet to an isolated lake as the ice retreated, affecting lake level and sedimentary processes.

Summary: The study presents a multiproxy analysis of sediment cores from the Northeast Greenland shelf, reconstructing the deglacial conditions and Holocene fluctuations in water masses. Results show that the shelf was deglaciated prior to 13.3 cal ka BP, with the presence of Atlantic Water beneath sea ice cover. The onset of high productivity and warmer water conditions occurred around 12.9 cal ka BP, followed by a cold period and enhanced East Greenland Current incursion. The Holocene Thermal Maximum period saw increased Atlantic Water flow and high productivity, while the Neoglaciation period was characterized by colder conditions and increased drift-ice transport via the East Greenland Current.

Summary: This study investigates the sediment record of Sugan Lake in the Qaidam Basin to understand the Holocene climate variations in the region. It reveals that during the Holocene Megathermal Maximum, there was high evaporation and sparse terrestrial vegetation due to high temperatures, resulting in a SO42--type water characteristic. After ca. 5800 cal a BP, there was a shift to Cl-type water and intensified aeolian activities. Between 5800 and 3580 cal a BP, a higher lake level and cool and wet conditions were inferred, with the weakening of the East Asian Summer Monsoon (EASM) and intensification of the westerly jet. After 3580 cal a BP, colder and drier conditions prevailed, possibly due to the strengthening of the mid-latitude westerly circulation. However, the EASM briefly prevailed at around 3580-3000 cal a BP and 1800-810 cal a BP. The Little Ice Age fluctuations between 580 and 280 cal a BP were characterized by cold/dry, cold/wet, and cold/dry conditions, accompanied by increased aeolian activities and risen lake levels.

Summary: The study of lake-bed sediments in Schirmacher Oasis, East Antarctica, reveals rare glacial-interglacial climatic and environmental variations and limited data on the past behavior of the East Antarctic Ice Sheet (EAIS). Magnetic properties of sediments from a radiocarbon-dated core show low values during the Holocene and high values during the last glacial period, indicating strong physical weathering in the catchment area. Shifts in magnetic properties during deglaciation and climate events such as the Antarctic Cold Reversal and the Early Holocene Climate Optimum are documented in the study.

Summary: Glacier-fed streams (GFSs) are extreme and rapidly disappearing ecosystems that harbor diverse microbial communities. A novel analytical framework called phyloscore analysis identified clades with lower spatial phylogenetic turnover in sediment microbiomes across twenty GFSs in New Zealand. These clades, constituting up to 44% and 64% of community alpha-diversity and abundance, showed increased alpha-diversity and abundance as sediment chlorophyll a decreased, indicating their ecological success in GFS habitats.

Summary: The study conducted on 101 glacier-fed streams from six major regions worldwide found that glacier shrinkage accelerates organic matter decomposition rates in benthic biofilms. Factors such as algal biomass, chytrid fungi parasitism, and stream water characteristics play important roles in promoting decomposition. Additionally, different bacterial classes possessing varying proportions of EEA-encoding genes may influence microbial associations with decomposition rates in glacier-fed streams.

Summary: Due to climate change, the glaciers on Africa's 'Mountains of the Moon' in Rwenzori National Park, Uganda are expected to disappear within the next few decades. This will result in the disappearance of the glacier-fed streams and their resident microbial communities. A study on the benthic microbiome from the Mt. Stanley glacier-fed stream showed distinct differences from other glacier-fed streams, with the presence of novel taxa and different abundances of common groups. The primary producer community in this stream is rich, likely due to the greater environmental stability of the Afrotropics, and heterotrophic processes dominate the bacterial community.

Summary: Glaciers worldwide are melting at an accelerated rate due to climate change, with increasing air temperature and uncertain precipitation patterns being the main factors. While surface glaciers have been well studied, little is known about the response of cave glaciers to atmospheric warming. Extreme precipitation events in Southeast Europe in 2019 had a significant impact on both surface and cave glaciers in the region, with projections indicating that such events will increase in frequency and intensity in the future.

Summary: Small glaciers in temperate mountain regions have experienced significant reduction and unprecedented melt rates in recent years. Some glaciers have transitioned from clean ice to debris-covered or even rock glaciers. This study examines the surface elevation change of the Popera Alto glacier in the Sesto Dolomites using LiDAR and Structure from Motion surveys, and analyzes its evolution in terms of surface cover and geomorphic processes. The glacier has lost an average of 0.35 m water equivalent per year over the past 16 years, with active modification of its surface cover by geomorphic processes. The role of debris and local topography feedback has allowed the resilience of the glacier, leading to a marked difference between the current environmental equilibrium line altitude (envELA) and the effective ELA (effELA) of the glacier.
