Summary: Anthropogenic climate change has profound effects on ocean environmental conditions, impacting marine ecosystems in ways that may be difficult to reverse. Identifying, monitoring, and preventing these changes, including tipping points, is an ongoing research effort that requires feasible mitigation strategies based on research. Addressing high-probability high-impact ocean tipping points in combination with gradual changes is crucial to prevent compounding negative impacts on society and the Earth system.

Summary: Climate change necessitates adaptive measures in food production systems, particularly in marine fisheries. Incremental adaptation has proven to be insufficient, thus transformative adaptation offers an opportunity for a timely transition towards climate-resilient conditions. Transformative adaptation in fisheries, taking into account past non climate change-oriented deep transformations and the unique attributes of marine fisheries, should be implemented locally and regionally but designed globally. Two transformational options are proposed: prioritizing food security and adopting a climate-responsive ecosystem approach for fisheries management. Successful adoption hinges on addressing scientific uncertainty, political will, risk perception, regulatory processes, and financial costs through international cooperation, information flow, stewardship mechanisms, and traceable compliance evidence.

Summary: The North American Arctic Ocean has a negligible impact on global methane and nitrous oxide budgets, with sediments and water column consumption being significant sources of methane in the region. Rivers do not play a significant role in methane and nitrous oxide concentrations in the Arctic Ocean.

Summary: Marine cyanobacteria, major contributors to the oceanic carbon sink, undergo significant proteomic alterations in major nutrient metabolism pathways in response to temperature changes. As seawater temperatures rise, the composition and nutrient demands of cyanobacteria are likely to be altered, impacting their contribution to oceanic biogeochemical cycling.

Summary: Anthropogenic stressors from climate change can impact individual species, community structure, and ecosystem function. Marine heatwaves (MHWs), characterized by significantly elevated water temperature for five or more days, are projected to increase in frequency and severity. While marine protected areas (MPAs) may mitigate climate impacts on individual species, their ability to address large-scale changes in marine communities caused by MHWs is uncertain.

Summary: Ocean deoxygenation is a growing concern for marine ecosystems, influenced by human activities. Changes in oxygen concentrations are affected by both oxygen supply and demand, with biogeochemical processes shaping oxygen demand in certain regions while ventilation changes dominate in others. Improved understanding and representation of these processes in Earth System Models is crucial for accurate projections of ecosystem risk and vulnerability.

Summary: This study used three biogeochemical models to investigate the changes in marine nitrogen cycle under a high CO2 emissions future scenario. The representation of iron had a significant impact on global nitrogen fixation, especially in the Eastern boundary upwelling zones, where bottom-up control of iron limitation played a key role in reducing export production with warming.

Summary: Microplastics, due to their small size, can be ingested by phytoplankton and zooplankton, impacting their sinking rates and subsequently affecting marine ecosystems and carbon uptake. This study used a complex model to analyze the effects of microplastics and found that the slowing of sinking rates reduces ocean carbon uptake and has significant impacts on ecosystems regionally. Plastics carbon has a much greater impact on marine ecosystems than atmospheric carbon over a centennial timescale.

Summary: This study conducted an experiment in Raunefjord, Norway involving the simulation of extreme pCO2 levels in coastal regions, and found that high CO2 conditions significantly impacted the structure of plankton communities, leading to a substantial reorganization of the planktonic food web.

Summary: In this study, the performance of a statistical forecasting system for marine-litter concentration in the Mediterranean Sea is explored. The system is based on the analogues method and uses a historical database of simulated marine-litter concentration. Different approaches have been tested to improve the system and the results show that integral definitions for the similarity function based on the history of meteorological situations improve the system's performance. The system has potential to become a cost-effective forecasting method for marine-litter concentration.

Summary: The marine coastal region, accounting for only 10% of the global ocean area, contributes nearly 20% of its total primary production and over 80% of fisheries landings. Unicellular phytoplankton dominate primary production. Climate variability has impacted marine ecosystems, but it is too early to differentiate ecological responses to long-term climate trends.
