Summary: The relationships between changes in meteorological conditions and diatom fluxes and taxonomic composition were investigated in two small lakes. The results showed that changes in meteorological conditions indirectly influenced diatom fluxes through changes in mixing regimes that affected nutrient and light availability. Statistical analyses demonstrated correlations between diatom data and air temperature and wind speed, although their influence on diatom assemblages was likely a surrogate for the complex changes in lake structure. Differences in specific diatom taxa succession and taxonomic composition were attributed to local conditions such as lake hydrological types, littoral zone extent, and sunlight exposure.

Summary: This paper introduces a statistical model called the sea level simulator v1.0 which incorporates mean sea level change and sea level extremes into a joint probabilistic framework. The model estimates flood risk as a function of height above the current mean sea level through Monte Carlo simulations. The simulator is lightweight and adaptable, and its flood risk estimates are well suited for adaptation and decision problems.

Summary: The coastal areas of the Mediterranean Basin exhibit significant variability in tectonic behavior and coastal landforms consistent with sea level change models. Although most surveyed sites have been tectonically stable since the last interglacial period, only a small portion of the coast retains fossil markers of past sea levels.

Summary: This study presents a post-glacial relative sea level (RSL) curve for the Central Douglas Channel region on the northern Northwest Coast of North America spanning the last 14,500 years. The research indicates that central Douglas Channel was ice-free following the Last Glacial Maximum by-14,500 BP, with RSL at least 90 m higher than today. Isostatic rebound caused RSL to fall to 21 m asl by 11,500 BP, and it eventually reached its current position around 1800 years ago. Long-term RSL reconstructions are crucial for understanding coastal changes and early coastal occupations.

Summary: Southern Ocean phytoplankton production is crucial for supporting Antarctic marine ecosystems, but anthropogenic climate change may lead to shifts in phytoplankton community structure, affecting the whole ecosystem. Simulation results suggest that different responses of phytoplankton in the Antarctic Circumpolar Current region and the sea ice zone may have implications for higher trophic levels.

Summary: The study tracked changes in shallow marine habitat availability due to Pleistocene sea level fluctuations and assessed correlations with past changes in genetic diversity in Caribbean hawksbill turtles. Results showed a strong correlation between changes in habitat availability and genetic diversity of hawksbill turtles, with a rapid increase in both factors after the Last Glacial Maximum. These findings suggest a positive correlation between Pleistocene environmental changes, habitat availability, and species' demography.

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: With the help of paleolimnology, the relationship between diatoms and environmental drivers in the Arctic lakes and ponds of Greenland was explored. The study found that climate and lake ontogeny were the main factors determining diatom communities. The species diversity declined towards the North, and diatoms were proven to be an excellent proxy for climate-mediated lake ecosystem change in the Arctic.

Summary: Studies project that climate change will lead to a significant number of excess deaths, with hotter and poorer places being more adversely affected. Without income-based adaptation, global mortality is expected to increase, but the increase is lower when income is considered. The current estimates of climate-change induced excess mortality are likely underestimated in current SCC calculations.

Summary: Human-caused carbon dioxide emissions will have long-lasting impacts on global temperatures and sea levels. Many major cities, particularly in Asia, will face unprecedented exposure levels from sea level rise. Countries like China, India, Indonesia, and Vietnam have large populations residing in areas vulnerable to high tide lines, while small island nations are at risk of near-total loss. Meeting the goals of the Paris Climate Agreement could significantly reduce the exposure and protect coastal megacities from extensive defense requirements.

Summary: The study at Yunlong Lake in Southwest China demonstrates the environmental sensitivity and utility of diatom transfer functions for quantitative reconstruction of regional climate change. The research highlights the relationship between temperature and water level variations, as well as the sensitivity of diatoms to short-term precipitation fluctuations and long-term water level rise. The findings serve as a foundation for using lake diatom records in paleoclimatic reconstruction on various timescales.

Summary: Plot-level photography is a time-saving alternative for vegetation monitoring, but its widespread adoption depends on efficient post-processing workflows and accurate results. In this study, relative vegetation cover was estimated using both traditional field sampling and semi-automated classification of photographs in Alaska. The results show that plot-level photography can accurately predict the cover of graminoids, but its accuracy is limited for other vegetation classes.

Summary: The study suggests that the North American and Eurasian Ice Sheets were the primary contributors to the rapid global sea-level rise event, Meltwater Pulse 1A, during the last deglaciation. The results based on sea-level constraints align with field-based ice-sheet reconstructions, supporting the idea that the freshwater causing the sea-level rise mainly came from North America and Eurasia.

Summary: This paper presents a regional synthesis of the highest resolution palaeoclimate records in the eastern Mediterranean and compares them with archaeological evidence to re-evaluate the role of climate change in the `collapse' of Bronze Age societies. The results challenge the simple 'climate destroyed society' hypothesis and show a more complex record of changing aridity and societal response. This study has implications for understanding the relationship between climate and societal change.

Summary: The island of Cyprus has a long history of human impacts, including the introduction of more than 250 plant species. One of these introduced species is Juglans regia (walnut), which is considered a naturalised non-native (introduced in last 500 years). Here we report the earliest occurrence of Juglans regia pollen grains from a sedimentary deposit on Cyprus. The pollen recovered from the Akrotiri Marsh provides an earliest introduction date of 3,100-3,000 cal yr bp. This Bronze Age occurrence of Juglans regia is sporadic. However, by 2,000 cal yr bp the pollen signal becomes more persistent and indicates that introduction or expansion of Juglans regia was highly likely in the Roman period. We integrate our new results with younger pollen occurrences of Juglans regia on Cyprus, the archaeobotanical record and documentary evidence to provide an overview of this archaeophyte. Our findings show that, following the conventions of the Flora of Cyprus, Juglans regia should be reclassified from naturalised non-native to indigenous.

Summary: By analyzing observational data from Britain, France, and Denmark, it has been found that during the Last Interglacial, the Antarctic had a significant contribution to global sea-level rise, peaking in the early phase of the interglacial. These findings are important for understanding the response of ice sheets to climate warming.

Summary: Tsunamis are major hazards along coastlines around the world. To understand their impact, previous events need to be studied through their sedimentary deposits. By analyzing sediment cores and using statistical analysis, it is possible to identify multiple waves in the tsunami deposits, indicating a high-concentration basal component and capacity-driven deposition. A high-resolution numerical model confirms the presence of multiple waves, and the reconstruction of paleogeomorphology is crucial to understanding the hydrodynamics of a tsunami wave group.

Summary: The Greenland Ice Sheet has been losing mass at an accelerating rate over the past 2 decades. Salt marsh sediments collected at the mouth of Dronning Marie Dal in southeastern Greenland provide records of relative sea level changes over the past ca. 300 years. The modeled relative sea level predictions do not match the salt marsh observations, suggesting regional differences in the response of the Greenland Ice Sheet to climate change.

Summary: This study investigates the role and climatic impact of the opening of the Drake Passage during the Eocene-Oligocene transition. The research provides new data on terrestrial environments and palaeoclimate using palynomorph and lipid biomarker analysis. The findings reveal significant changes in terrestrial vegetation and suggest a link between the expansion of gymnosperms and cryptogams and repeated glacial expansion and retreat. Furthermore, the study indicates that the opening of the Drake Passage and Antarctic glaciation were not contemporaneous.
