Summary: Monitoring sea level changes and exploring their causes are important for predicting future climate change and sustainable development. This study investigates the basin-scale sea level budget using multiple sets of satellite data, finding that sea level rises significantly in certain ocean basins, with ocean mass being the main contributing factor and thermal expansion also playing a role.

Summary: Sea-level measurements from radar satellite altimetry have achieved a high level of accuracy and precision, allowing detection of global mean sea-level rise and attribution to greenhouse gas emissions. However, recent research suggests that there is still room for improvement in satellite altimetry performance. Reduced uncertainties would enable regional detection and attribution of sea-level change and improve estimates of ocean heat uptake.

Summary: Understanding the coastal sea level budget is crucial for studying sea level rise and future changes. This study presents the coastal sea level budget from 2005 to 2021 using various observations. Results show a discrepancy in the budget since 2016, similar to the global average. The main reason for this is the salinity drift of Argo buoys after 2016. Ignoring unrealistic coastal salinity trends, the global coastal sea level budget from 2005 to 2021 is closed with a residual trend.

Summary: The current coastal spatial planning in Sweden fails to consider the uncertainties and time dependence of sea level rise, resulting in inaccurate flood risk assessments. The study finds that extreme events dominate flood risk for shorter planning periods, while the risk of high sea level rise becomes more important for longer planning periods.

Summary: Total sea level changes from different methods can be affected by area inconsistency, leading to a global trend difference of approximately 0.3 mm/yr. Applying a consistent ocean area for averaging can improve the agreement between altimetry and mass + steric in trend. This finding may help explain discrepancies in past sea level budget studies.

Summary: Based on an analysis of global coastal segments, it is estimated that about 3% of the coastline requires protection to prevent coastal migration and large-scale land loss. For the remaining 97% of coastlines, an estimated land loss of 60,000 to 415,000 square kilometers and coastal migration of 17 to 72 million people is projected.

Summary: Sea level rise is a long-lasting consequence of climate change, and despite uncertainties, climate model-based projections are used to support decision-making. A community effort has been made to quantify high-end global sea level rise, providing additional information on potential future scenarios. The timing of ice shelf collapse in Antarctica is emphasized as a critical factor for sea level rise.

Summary: Global sea level rise is primarily caused by heating of the ocean and the input of freshwater from melting ice. This study shows that trends in sea level rise can also be accurately tracked by observing changes in ocean salinity. The results highlight the importance of measuring ocean salinity for monitoring global sea level changes.

Summary: Studying local sea level rise is crucial for coastal sustainability and resilience in the face of climate change. Using altimeter data from the Sentinel-3B and Jason-3 missions, the regional variability and accuracy of sea level rise rates around Taiwan were investigated, as well as the accuracies of three mean sea surface models. The results showed that sea level rise rates in the region were higher than the global average, and the accuracy of the models varied.

Summary: This article provides an overview of relative and absolute sea level rise in the Baltic Sea using various studies and models. It shows that the relative sea level rise in the Baltic Sea between 1995-2019 was between -5 to 4.5 mm/yr, with the southern area being more affected. The research also predicts a maximum relative sea level rise of 0.3 to 0.7 m in the Baltic Sea by 2100. In Estonia, the coastal area experienced a relative sea level rise of -1.1 to 3.1 mm/yr, with the west and southwest areas being most threatened.

Summary: The sea level rise in the subtropical oceans between 35 degrees and 20 degrees S in the Southern Hemisphere is faster than the global average, mainly due to the persistent upward trend of the southern annular mode. Climate models have failed to reproduce this feature accurately, highlighting the need to reduce model biases for reliable regional sea level projections.

Summary: The study presents a counterintuitive finding that in the future, despite intensified flooding caused by sea-level rise, the population in Bangladesh will still continue to migrate towards vulnerable coastlines. The model shows that while flooding accelerates the transition from agricultural to non-agricultural income opportunities, livelihood options are abundant in coastal cities, leading to some populations being "trapped" due to flood losses.

Summary: The study introduces an ensemble approach for quantifying historical global mean sea-level rise, which provides a conservative estimate of total uncertainty by combining internal and structural uncertainties. Comparisons with past assessments and satellite altimeter data show good agreement with the results. Sensitivity tests demonstrate the robustness of the estimates to variations in reference period and central estimate timeseries, indicating potential applications to other global or regional climate change indicators.

Summary: The effective climate sensitivity of CMIP6 models has increased compared to CMIP5, leading to higher projections of global surface air temperature and more pronounced differences in global mean sea-level rise rates around 2100. Early emission reductions are crucial for mitigating sea-level rise.

Summary: The study combines new and existing observations to determine that the sea-level rise trend in the South Atlantic Ocean during the 20th century likely ranged between 1.1 and 2.2 mm per year, with a central estimate of 1.6 mm per year. Both observations and physical processes indicate that the South Atlantic experienced sea-level rise about 0.3 mm per year above the global mean, attributed to factors such as ocean dynamics and ice mass loss.

Summary: This study investigates the impacts of tidal and wind changes on seed arrival and retention in salt marshes, essential for marsh regeneration. Results show that spring tides are more effective in seed dispersal than neap tides, and storm-induced extreme water levels deliver higher amounts of viable seeds. Seed retention decreases with increasing onshore wind speed, with storm-induced wave disturbance wiping out seeds on wind-exposed marshes.

Summary: Coastal areas are highly sensitive to sea-level change and play a crucial role in socio-economic activities. The future magnitude and rate of sea-level change are of great importance for coastal risk aversion and adaptation measures. Addressing this issue requires a transdisciplinary scientific community and close collaboration with local stakeholders.

Summary: This study reveals substantial seasonal differences in ocean dynamic sea level change (DSLC) on the Northwestern European Shelf (NWES), with higher DSLC in winter and spring compared to summer and autumn. The changes in winter and summer sea level anomalies are mainly driven by regional changes in wind stress anomalies, while changes in spring and autumn are less influenced by wind stress. CMIP6 models that do not resolve currents through the English Channel cannot accurately simulate the effect of seasonal wind stress changes on the NWES. Using projections of annual mean RSLC may underestimate the projected changes in extreme coastal sea levels in spring and winter.

Summary: Sea-level rise increases the likelihood of exceeding local protection infrastructure, and the authors propose a method to determine when the degree of local protection decreases. This study projects the timing of extreme sea level frequency amplification relative to estimated local flood protection standards. Results show that within the next 30 years, the frequency of exceeding protection standards will significantly increase at a high proportion of tide gauges under different emissions scenarios.
