Summary: This study uses different data sources to analyze the various contributors to Arctic sea level variability. The study finds that the global sea level rise is the dominant factor influencing Arctic sea level changes, while Arctic oscillation, steric sea level increase, and intrusion of Pacific water also contribute to the variability. Additionally, the melting sea ice and larger open water area alter the impact of atmospheric forcing on Arctic sea level, with ocean dynamic circulation playing a more significant role.

Summary: In this study, the contributions to Arctic sea level (ASL) variability from different physical processes were quantified using Ocean Reanalysis System 5 (ORAS5) reanalysis data, tide gauge, and satellite altimetry observations. Results showed that the rising trend of ASL is primarily attributed to global sea level increase, Arctic Oscillation-induced mass redistribution, steric sea level increase in the Beaufort Gyre region, and intrusion of Pacific water into the Arctic Ocean. Furthermore, the impact of large-scale atmospheric forcing on ASL variability changed significantly after 1995 due to dramatic sea ice melting and increased open water area, with ocean dynamic circulation playing a more important role.

Summary: The Lower-Upper Pleistocene sedimentary record of the Baklan Basin in SW Turkey reveals shallow lacustrine and palustrine deposits. The paleoenvironmental changes recorded in the basin allow for a multiproxy approach in reconstructing the paleoclimatic, paleoecological, and paleobiogeographical evolution of southwestern Anatolia during the Early-Late Pleistocene. The findings have significant implications for understanding the impact of tectonics, climate changes, and Caspian Sea transgressions on lacustrine and palustrine sedimentation.

Summary: The sea level in the Arctic remains uncertain, with disagreements between GRACE and satellite altimetry data. A study comparing different datasets found that the best agreement was reached using a combination of in-situ hydrographic data and altimetry products. However, a large residual signal was found in the East Siberian Sea, indicating uncertainties in satellite observations. Overall, caution is recommended when using satellite observations in the Arctic region to study sea level trends.

Summary: This study used a shallow sediment core retrieved from the Red Sea coastal zone in northern Ghubbat al Mahasin, south of Al-Lith, Saudi Arabia, for reconstructing mid-Late Holocene paleoenvironments and sea level changes using a multiproxy approach. The core stratigraphy revealed three distinctive depositional units, indicating a warm and humid climate during the basal unit, a lagoonal or shallow marine environment during the middle unit, and an intertidal flat during the upper unit. The findings suggest a late Holocene sea-level fall and a shift to a more arid climate.

Summary: Understanding sea ice variability and mechanisms during warm periods is crucial for comprehending current and future sea ice changes. This study uses the LOVECLIM model to simulate sea ice variations in the last nine interglacials and compares them to present and future conditions. Results show that Arctic sea ice is primarily controlled by local summer insolation, while Southern Ocean sea ice is influenced by CO2 concentration. Interglacials have less sea ice than the present, making them potential analogues for future sea ice changes in the Arctic. However, the higher CO2 concentration in interglacials leads to more sea ice in the Southern Ocean, suggesting that they are not appropriate analogues for the future in this region.

Summary: This paper analyzes the sea level variations in the Arctic Ocean over the past four decades using ORAS5 data. It reveals that the most significant characteristic of sea level variation in the region is its seasonal variability, which is closely linked to atmospheric circulation and sea ice formation. The analysis also shows that sea level in the Arctic Ocean has been continuously rising since the mid-1990s or early 2000s, with the most rapid rise occurring in the Beaufort Sea.

Summary: The Yorkshire Dales is an iconic agricultural landscape in Britain, with a long history of vegetation and fire. New palynological data reveal significant variation in vegetation history between different sites, likely influenced by topographic and edaphic factors. The data show a marked clearance of woodland starting from the Neolithic period, leading to the development of the contemporary agricultural landscape in the Yorkshire Dales.

Summary: The Margaret Formation at Stenkul Fiord in southern Ellesmere Island, Nunavut, Canada, is a continuous sequence of microfossil-rich clastic sediments and coal deposited during extensive tectonic activity linked to Eurekan deformation. A new high-resolution biostratigraphic framework for the formation has been established using a quantitative palynological approach, combined with new absolute age control provided by U-Pb ID-TIMS analysis of zircon. The presence of thermophilic pollen taxa in the strata indicates warm climates during the early Paleogene.

Summary: This study investigated the paleolimnological record of diatoms and climate in a small subarctic lake contaminated by gold smelting waste, revealing six distinct paleoecological assemblages of diatoms over time in response to changing local hydrological and sedimentological conditions. Environmental variables explained 28.8% of the variance in diatom assemblages, with significant correlations to different climate periods. The results demonstrate that paleoclimatic changes and industrial contamination have influenced the ecological evolution of the lake over the past 2800 years.

Summary: The geochemical record of the Christopher Formation on Axel Heiberg Island, Canada, indicates variations in redox conditions and the presence of carbon isotopic excursions associated with Oceanic Anoxic Event 1b (OAE 1b). The elevated concentrations of mercury in the formation are likely sourced from sulphide minerals rather than organic matter. The input of mercury into marine basins can be predominantly detrital, and there are no clear atmospheric sources of mercury anomalies associated with specific sub-levels of OAE 1b.

Summary: The cause of ice-age cycles is still not fully understood, and studying the timing and magnitude of mountain glaciations can provide valuable insights. This study presents new dating results from the Niqingqu Valley in the Tibetan Plateau, showing multiple glacial activities prior to the Penultimate Glacial Maximum. The findings suggest that low atmospheric CO2 content and reduced summer solar insolation/high summer-monsoon precipitation played a role in these glacial fluctuations.

Summary: Through sediment records from Lake Nanyi in the lower Yangtze, we found that anthropogenic fire activity played a dominant role in the region, and the temporal pattern of fire activity was asynchronous from east to west. Archaeological evidence suggests an inverse relationship between agricultural and population levels and fire intensity during the mid-Holocene, with fire intensity being influenced by the diversity of landscape types associated with pre-historic subsistence patterns. Overall, changes in regional water-level delayed the transition from hunting-gathering to agriculture in the lower Yangtze region.

Summary: This paper argues that sessile barnacles are an excellent proxy for palaeoenvironmental reconstructions. The shells of barnacles consist of diagenetically stable low-magnesium calcite and record short-term variations. Analyses of several Western Mediterranean barnacle-rich deposits demonstrate the utility of barnacles as proxies for water depth, distance from the coastline, and hydrodynamic conditions. Moreover, the stable isotope ratios of barnacle shells can provide detailed palaeoenvironmental information.

Summary: The Late Ordovician mass extinction occurred during an ice age, with maximum ice coverage and a substantial drop in global sea level. This led to the exposure or shallowing of shallow tropical shelf environments. The study suggests that the burial rate of nutrient phosphorus (P) on shelves was minimal during this glacial period, leading to excess bioavailable P entering the open ocean and stimulating phytoplankton production, which in turn lowered oxygen concentrations.
