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: Ocean acidification can affect marine molluscs, but transgenerational plasticity may mitigate some effects. This study investigated how the microbiome can be influenced by transgenerational exposure to ocean acidification in Sydney Rock oysters. The results showed that parental exposure to elevated PCO2 altered the bacterial community composition in both eggs and larvae, with certain Rhodobacteraceae ASVs increasing or decreasing in abundance. These findings suggest that the transfer of maternal microbiomes to larvae is affected by exposure to ocean acidification and may contribute to transgenerational plasticity.

Summary: This study investigates the growth response of Arctic diatom Chaetoceros gelidus under varying CO2 and light levels. The results suggest that this species has a high adaptability to variable light levels and is capable of accumulating substantial amounts of organic carbon at low CO2 levels. Additionally, under nitrogen limitation, intracellular nitrogen resources may be recycled, resulting in an increased carbon-to-nitrogen ratio within the cells.

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: This study aimed to evaluate the impacts of pharmaceutical drugs and acidification on edible clams. The results showed that the combination of drugs had fewer impacts on the clams compared to when the drugs were acting alone. Acidification had negative effects on the clams, but it did not enhance the toxicity when combined with pharmaceutical drugs.

Summary: This study investigated the impact of ocean acidification on larval energetics of oysters and found that elevated p CO2 reduced survival, size, and lipid levels across all lipid classes. Larvae of Saccostrea glomerata were more impacted than Crassostrea gigas, especially when food was limited, highlighting concerns for their aquacultural status and ecological function.

Summary: The increasing connections between ocean sustainability and climate change are highlighted, with a focus on how ocean actions are being framed as relevant for climate mitigation and adaptation. This review also discusses the overlapping or conflicting efforts to address ocean health and climate change through international processes.

Summary: Ocean acidification is a highly studied topic in climate change due to its direct and indirect impacts on species, ecosystems, and economies. Challenges remain in incorporating pH ranges and variability into experiments and analyzing ecosystem-level impacts. Models and experiments need to be better aligned to determine the effects of future pH levels on commercially exploited species.

Summary: Anthropogenic climate change is predicted to have significant impacts on the marine ecosystems of the Eastern Boundary Upwelling Systems (EBUS), particularly through ocean acidification and changes in upwelling dynamics. A study focusing on the California Current Upwelling System (CCUS) showed an increase in upwelling-favorable winds, affecting seasonal upwelling transport. The observed changes in wind trends are consistent with trends in water chlorophyll-a, CO2 partial pressure, and pH analysis, highlighting the importance of these changes for modulating the carbonate system within the CCUS.

Summary: Research suggests that genetic variations among oysters may influence their microbiome response to climate change. This study focused on how different breeding lines of Sydney rock oysters responded to climate change conditions and found that the microbiomes were altered based on genetic backgrounds. Future breeding programs should take into account the impact of oyster microbiomes in enhancing resilience to climate change.

Summary: The study found that in a stable elevated pCO(2) environment, both species of coral reef fishes showed a consistent brain molecular response, including the downregulation of immediate early genes. The transcriptional program was more strongly affected by higher average pCO(2) in stable conditions. The largest difference in molecular response was between stable and fluctuating pCO(2) treatments, indicating that the response to environmental pCO(2) conditions differs for organisms living in fluctuating versus stable environments.

Summary: Recent experimental studies on the impact of climate change on marine ecosystems have increased, with a focus on single species and laboratory-based research. However, there has been a significant increase in multiple stressor experiments, as well as studies on behavioral responses, transgenerational effects, and extreme climate events.
