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: This study quantitatively assesses the steric changes associated with sea level rise in the upper South Indian Ocean (SIO) from 1993-2017, using the latest ocean state estimate and in-situ observations. The results show that the sea level rise in the low-latitude SIO is faster than the South Pacific and South Atlantic counterparts. The fast sea level rise is mainly attributed to warming and freshening of the upper ocean, with little contribution from the deeper layers.

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: This study aimed to estimate the potential risk of the combined effect of global change factors and microplastic pollution on the growth and development of the sea urchin P. lividus. The results showed that exposure to decreased pH and microplastic caused a significant decrease in larval growth, while an increase in water temperature added additional stress, resulting in lower growth and altered development of the sea urchin larvae. The combined stress of ocean warming, acidification, and microplastic pollution may threaten sea urchin populations and have a potential impact on coastal ecosystems.

Summary: Estimating future sea level rise is crucial for coastal risk assessment and climate-resilient infrastructure planning. This study utilized CMIP6 models to project future sea level rise under different climate targets, finding that SLR projections are more intense with global warming both globally and around the Korean Peninsula. Ocean variables show a slow response to climate change, with the Emergence of Climate Change index indicating that SLR will accelerate after the 1.5°C warming period.

Summary: Accurately monitoring sea level changes is crucial for understanding and projecting future sea level rise and supporting adaptation strategies to climate change. Altimeter sea level products from EU Copernicus services provide important indicators for this purpose. By presenting key scientific questions, processing steps, and specific indicators such as global mean sea level evolution and regional sea level trends, these products can better support adaptation to sea level rise.

Summary: Many African heritage sites are currently at risk from rising sea levels, which could more than triple under high emissions scenarios. Mitigating emissions can reduce the number of highly exposed sites. These findings highlight the urgent need for increased climate change adaptation for heritage sites in Africa, including governance, vulnerability assessments, monitoring, and protection strategies.

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: Changes in ocean heat content are sensitive to the vertical interpolation of sparsely sampled data and estimates relying on simple linear interpolation schemes underestimate the increase in upper ocean heat content. Using high-quality hydrographic data and carefully constructed methods, this study finds a 14% larger increase in observationally based upper ocean heat content compared to previous estimates.

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 ocean serves as a major sink for anthropogenic heat and carbon, but the trajectories of heat and CO2 uptake diverge over the 21st century due to regional differences in physical and chemical drivers. Regional variations in heat-to-carbon uptake ratios will result in coherent regional patterns for sea surface warming and acidification by the end of this century.

Summary: The Antarctic surface mass balance (SMB) is an important factor in regulating global sea level changes. By combining ice core records, reanalysis products, and climate models, this study provides a comprehensive reconstruction of the spatial and temporal complete SMB over the Antarctic Ice Sheet (AIS) for the past 310 years. The results show a significant positive trend in SMB over the entire AIS, with a larger increase rate since 1801. This increased SMB has cumulatively dampened global sea level rise, although the dynamics of the ice sheet were not considered.

Summary: Earth's Energy Imbalance (EEI) is the difference between global mean solar radiation absorbed and thermal infrared radiation emitted to space, mainly warming the ocean and affecting land, ice, and the atmosphere. Over the past decade, EEI has shown an increasing trend primarily due to decreased reflection by clouds and sea ice, as well as increases in trace gases and water vapor leading to a decrease in outgoing longwave radiation.

Summary: This article discusses the statistical climatology of depth, temperature, and salinity in the global ocean surface mixed layer. The properties of the mixed layer are influenced by various factors that operate over different time scales. The depth of the mixed layer can change rapidly due to surface heating, precipitation, or density gradients, but deepening the mixed layer requires substantial buoyancy loss or strong wind mixing, which takes more time. The distribution of mixed layer depth is skewed positive, with temperature and salinity exhibiting different characteristics in different regions.

Summary: This study uses a global high-resolution ocean/sea-ice simulation and passive tracer deployments to examine the export pathways of Antarctic Bottom Water (AABW). The results show that AABW from different source regions are blended during their export, with Weddell Sea- and Prydz Bay-sourced AABW mainly exported to the Atlantic and Indian Oceans, while Ross Sea- and Adelie Land-sourced AABW mainly exported to the Pacific Ocean. This has important implications for the three-dimensional structure of the global overturning circulation.

Summary: Satellite, reanalysis, and ocean in situ data were used to analyze the trends in Earth's energy fluxes during the first 20 years of the twenty-first century. The study found regional, hemispheric, and global variations in these trends, with significant differences observed between different datasets. The analysis also revealed agreement between the trend patterns observed in oceanic heat transfer and the difference between top-of-atmosphere and surface fluxes.

Summary: A study finds a decadal warming trend in Antarctic bottom water within the western Argentine Basin, showing a similar magnitude but greater certainty compared to previous studies. The analysis also reveals a faster warming rate in the coldest water entering the basin than in the interior. The reduction in deep meridional temperature gradient suggests a decrease in geostrophic shear and the flow rate of the coldest water.

Summary: The global seasonal cycle of energy in Earth's climate system is quantified using observations and reanalyses. Closure of the global seasonal energy budget is achieved by limiting the local vertical integration of new global ocean heat content estimates to the depth to which seasonal heat energy is stored.

Summary: Studying the behavior of deep-sea animals is challenging, but animal-borne camera tags may help understand predator-prey interactions. Research showed that camera-associated white light may affect foraging behavior, but has minimal long-term fitness impact on sperm whales. However, this impact should be considered and monitored for longer camera tag deployments.
