Societal Impact Statement Seagrass ecosystems are of fundamental importance to our planet and wellbeing. Seagrasses marine flowering plants, which engineer that provide a multitude ecosystem services, for example, blue foods carbon sequestration. have largely been degraded across much their global range. There is now increasing interest in the conservation restoration these systems, particularly context climate emergency biodiversity crisis. The collation 100 questions from experts Europe could, if answered, improve ability conserve restore systems by facilitating shift success such work. Summary meadows numerous services including biodiversity, coastal protection, In Europe, seagrasses can be found shallow sheltered waters along coastlines, estuaries & lagoons, around islands, but distribution has declined. Factors as poor water quality, modification, mechanical damage, overfishing, land‐sea interactions, change disease reduced coverage Europe’s necessitating recovery.

Earth's biodiversity and human societies face pollution, overconsumption of natural resources, urbanization, demographic shifts, social economic inequalities, habitat loss, many which are exacerbated by climate change. Here, we review links among climate, biodiversity, society develop a roadmap toward sustainability. These include limiting warming to 1.5°C effectively conserving restoring functional ecosystems on 30 50% land, freshwater, ocean "scapes." We envision mosaic interconnected protected shared spaces, including intensively used strengthen self-sustaining the capacity people nature adapt mitigate change, nature's contributions people. Fostering interlinked human, ecosystem, planetary health for livable future urgently requires bold implementation transformative policy interventions through institutions, governance, systems from local global levels.

Climate change and human activities increasingly threaten lakes that store 87% of Earth’s liquid surface fresh water. Yet, recent trends drivers lake volume remain largely unknown globally. Here, we analyze the 1972 largest global using three decades satellite observations, climate data, hydrologic models, finding statistically significant storage declines for 53% these water bodies over period 1992–2020. The net loss in natural is attributable to warming, increasing evaporative demand, consumption, whereas sedimentation dominates losses reservoirs. We estimate roughly one-quarter world’s population resides a basin drying lake, underscoring necessity incorporating impacts into sustainable resources management.

Methane (CH4) is a potent greenhouse gas and its concentrations have tripled in the atmosphere since industrial revolution. There evidence that global warming has increased CH4 emissions from freshwater ecosystems1,2, providing positive feedback to climate. Yet for rivers streams, controls magnitude of remain highly uncertain3,4. Here we report spatially explicit estimate running waters, accounting 27.9 (16.7-39.7) Tg per year roughly equal those other systems5,6. Riverine are not strongly temperature dependent, with low average activation energy (EM = 0.14 eV) compared lakes wetlands 0.96 eV)1. By contrast, patterns characterized by large fluxes high- low-latitude settings as well human-dominated environments.

Inland waters (rivers, reservoirs, lakes, ponds, streams) and estuaries are significant emitters of methane (CH4 ) nitrous oxide (N2 O) to the atmosphere, while global estimates these emissions have been hampered due lack a worldwide comprehensive data set CH4 N2 O flux components.

Despite its well-established negative impacts on society and biodiversity, eutrophication continues to be one of the most pervasive anthropogenic influences along freshwater marine continuum. The interaction between climate change, particularly warming, was explicitly focused upon a decade ago by Brian Moss others in "Allied attack: change eutrophication," which called for an integrated response both problems, given their apparent synergy. In this review, we summarise advances theoretical framework empirical research issue analyse current understanding major drivers mechanisms can enhance eutrophication, vice versa, with particular focus shallow lakes. Climate affect nutrient loading through changes at catchment landscape levels affecting hydrological patterns fire frequency temperature effects cycling. Biotic communities interactions also directly indirectly affected leading overall weakening resilience impacts. Increasing evidence now indicates several eutrophying aquatic systems increasingly act as important sources greenhouse gases atmosphere, methane. We highlight potential feedback among cyanobacterial blooms, change. Facing challenges simultaneously is more pressing than ever. Meaningful strong measures waterbody are therefore required if ensure ecosystem safe water supply, conserve decrease carbon footprint freshwaters.
