Owing to geographic differences, Arctic and Antarctic sea ice have different dominant properties and processes, which in turn produce different responses to natural climate variability and anthropogenic climate change. This Review surveys the changes in sea-ice properties and processes of the Arctic and Antarctic environments. The Arctic melt season has lengthened by ~7.4 days per decade during 1979–2024, alongside decreases in winter sea-ice thickness (1.6 m mean total over 1980–2023), summer surface albedo (0.03 per decade over 1979–2020) and spring snow depth (2.5 cm per decade over 1954–2024). Changes in the Antarctic are smaller than those in the Arctic owing to contrasting regional and temporal trends. From a dynamic perspective, sea-ice motion in both hemispheres has increased, by 0.63 cm s–1 per decade in the Arctic (1978–2024) and 0.69 cm s–1 per decade in the Antarctic (1982–2024), whereas trends in polynya occurrence differ by region. This Review highlights major knowledge gaps and provides recommendations for joint model-observation efforts to improve understanding of sea ice and its role in Earth’s climate system. Sea ice modulates the energy exchange between the atmosphere and ocean through complex, time-varying processes. This Review describes changes in Arctic and Antarctic sea-ice properties and processes, discusses the future sea-ice environment and provides recommendations to improve understanding of sea ice and its role in Earth’s changing climate.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"7 10","pages":"688-707"},"PeriodicalIF":74.1,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149100759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Contrary to the assumption that minerals primarily stabilize organic matter, iron minerals also control the release, conversion and mineralization of associated organic carbon through dissolution, phase evolution and photo-oxidation. Concurrently, DOM modulates the photoreduction, transformation and reactivity of iron minerals via light-mediated electron transfer and photochemically generated reactive oxygen species. These mineral–organic interactions are shaped by environmental variables and molecular characteristics that exert a marked influence on the mobility, speciation and transformation of associated contaminants, particularly at dynamic environmental interfaces. This Review focuses on the reactivity, vulnerability and spatial heterogeneity of iron and carbon pools in response to solar radiation and provides an update on how light shapes the coupling of iron and carbon cycles in terrestrial and aquatic surface systems. Field observations integrated with laboratory experiments, and advanced analytical techniques could enable the photochemistry of iron minerals and DOM to provide a framework for improved understanding of the biogeochemical cycling of iron, carbon and contaminants, refining carbon budgets and informing sustainable remediation strategies. Iron minerals and dissolved organic matter contribute to elemental cycling, contaminant dynamics and biogeochemical processes. This Review provides an update on iron mineral–dissolved organic matter photochemistry and highlights research priorities that could improve climate model predictions, the accuracy of carbon budgets and understanding of contaminant behaviour under sunlight.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"7 9","pages":"591-611"},"PeriodicalIF":74.1,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148904447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this Review, we synthesize physical, sedimentological and biogeochemical evidence to explore how and why SPM concentration, composition and size vary along the land–ocean continuum. Despite the large variability in SPM characteristics, its concentration is robustly correlated with its composition, size, density and settling velocity. In general, organic matter content and floc size increase with decreasing SPM concentration. In addition, flocs are small and consist mostly of minerals in turbidity maximum zones, with particle size and organic matter content increasing as waters become clearer. SPM concentrations also influence carbon partitioning, with the ratio of particulate to dissolved organic carbon increasing with SPM concentration. Therefore, SPM concentrations can reflect a combination of physical and biogeochemical processes and ecosystem properties. Climate change and human activities, such as dam construction and land use change, are perturbing SPM dynamics, with implications for wetland stability, contaminant mobility and carbon export and sequestration. Future research should prioritize in situ and remote sensing observations to constrain anthropogenic perturbations of SPM dynamics in natural systems and improve understanding of the implications for sediment accretion or erosion, pollutant mobility and the carbon cycle. Suspended particulate matter (SPM) influences the transport and fate of carbon and environmental contaminants in natural aquatic systems.

Subsurface environments are estimated to host over 30% of all microorganisms on Earth, with microbial communities having important roles in various groundwater processes. Discoveries of diverse and novel lineages of archaea, bacteria, microeukaryotes and viruses in groundwater have highlighted the key contributions of groundwater microbiomes to elemental cycling, contaminant degradation, pathogenicity and antimicrobial resistance. In this Review, we summarize the diversity and composition of prokaryotic, microeukaryotic and viral communities in groundwater, and describe the complex interactions between these different microbial groups. Groundwater microbiomes exhibit distinct biogeographic patterns, with key differences and similarities across groundwater types and other habitats. The community assembly of microorganisms across different groundwater environments is driven primarily by stochastic processes, whereas deterministic processes caused by environmental stress further modulate community structure and function. With regard to their function, groundwater microbiomes have crucial roles in shaping ecosystem functioning, including biogeochemical cycling, water quality and One Health. Finally, we highlight several future prospects for research to harness microbiomes as eco-sustainable solutions for groundwater restoration and protection in a changing world. Groundwater hosts a vast array of microbiomes that are essential to global water quality and ecosystem function. This Review discusses the diversity, biogeography and community assembly of the groundwater microbiome, and explores its role in biogeochemical cycling and sustainable groundwater management.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"7 9","pages":"570-590"},"PeriodicalIF":74.1,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148904393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their use has led to contamination of soils with microplastics (MPs), nanoplastics and associated chemical additives. In this Review, we synthesize evidence on the global use of PAFs, their environmental fate and strategies to enhance their sustainable application. PAFs deliver substantial agronomic benefits, enhancing crop yields by 7–48% and soil water retention by 9–25%. However, films fragment and degrade under physical erosion, elevated ultraviolet radiation, temperature, humidity, and microbial and faunal activity. As a result, PAF use generates 3–5 Mt yr−1 of largely unmanaged waste, contributing to widespread plastic pollution in agricultural soils. For example, MP concentrations can reach ~13,000 items per kilogram, with PAFs accounting for 10–30%. Conventional polyethylene films degrade slowly and primarily undergo physical fragmentation, whereas biodegradable films fragment more rapidly, with cases of ~30% converted to MPs within 2 years. However, complete mineralization remains limited even for biodegradable materials. Additives in PAFs, including poorly characterized non-intentionally added substances, further increase environmental and toxicological risks, and their release varies substantially with environmental conditions and film type. MPs and additives affect soil health, crop yields and nutrient cycles. Mitigation strategies include substitution with safer additives, developing biodegradable waste-derived bio-based polymers, and conventional film recycling. Future work should improve field monitoring, develop a global database of PAF use and composition, and implement policy innovations to support sustainable PAF systems. Plastic agricultural films enhance crop productivity and support food security, but their use also contaminates soils with plastics and chemical additives. This Review examines the global production and use of agricultural films, their environmental impacts, and strategies to support their sustainable production and use.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"7 8","pages":"528-545"},"PeriodicalIF":74.1,"publicationDate":"2026-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148696683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
