Oxygen fugacity (fO2), which quantifies the availability of oxygen to mediate oxidation–reduction reactions, affects important mantle processes, such as depth of melting, extraction of volatiles to the atmosphere, crustal composition and ore body generation. Debate continues over modern and past variations in mantle fO2. In this Review, we compile thermobarometric data from mafic and ultramafic rocks at ridges, back-arcs, and arcs and show that the fO2 of subduction-influenced arc mantle is appreciably higher than the mantle supplying ocean ridges. We review the timing and mechanisms that might transfer redox budget to the arc mantle wedge. A new proxy for the redox-sensitive element vanadium confirms the higher oxidation state of arc mantle and can be used to show there is no conclusive evidence for oxidation of the ambient mantle since the Archaean (2,500–4,000 million years ago). Earlier, in the Hadean magma ocean (>4,000 million years ago), liquid silicate equilibrated with liquid metal alloy while the upper mantle was rapidly oxidized to higher fO2. Future research should focus on how mantle fO2 coevolved with Earth’s primitive atmosphere during core formation, magma ocean crystallization and degassing. Mantle oxygen fugacity is set by phase equilibria and is intimately linked to geochemical and geodynamic processes. This Review explores the possible mechanisms that have controlled mantle oxygen fugacity from Earth’s early beginnings to the present day.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"6 11","pages":"728-746"},"PeriodicalIF":0.0,"publicationDate":"2025-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145450131","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 Perspective, we compare five FLUC estimation approaches, discuss the origins of large uncertainties and discrepancies in estimates and consider how to improve estimate accuracy and better align individual estimates. Global FLUC estimates between 2000 and 2023 range from net emissions of 1.9 ± 0.6 PgC yr−1 (based on dynamic global vegetation models) to net removals of −1.0 PgC yr−1 (based on Earth observations), with other estimates from bookkeeping models, country reports and atmospheric inversions falling within this range. Discrepancies arise from each approach using different definitions for FLUC, the spatial extent of managed land and including degradation and environmental effects to varying degrees. As a result, each approach accounts for different fluxes and land areas. Uncertainties within individual estimates are attributed to quality of land-use data, observational constraints and incomplete process consideration. These uncertainties can be reduced through better separation of anthropogenic and natural CO2 fluxes, including the effects of anthropogenically driven ecosystem degradation and improving model parameterizations. Thus, future research should prioritise unambiguous and consistent definitions and conducting systematic evaluations against each other to improve the translation and harmonization of FLUC estimates, which is essential to support effective climate policies and optimize land-based climate change mitigation. Robust quantification of carbon dioxide fluxes from land use is critical for guiding climate change mitigation efforts and for improved understanding of the global carbon cycle. This Perspective explores the origins of uncertainties and discrepancies in established estimation approaches and considers strategies to improve, translate and harmonize flux estimates.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"6 11","pages":"747-766"},"PeriodicalIF":0.0,"publicationDate":"2025-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145450128","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 evaluate historical and projected changes in rare Arctic extremes across the atmosphere, cryosphere and ocean and elucidate their driving mechanisms. Clear shifts occur in mean and extreme distributions after ~2000. For instance, pre-2000 to post-2000 observational probabilities of 1.5 standard deviation events increase by 20% for atmospheric heat waves, 76.7% for Atlantic layer warm events, 83.5% for Arctic sea ice loss and 62.9% for Greenland Ice Sheet melt extent — in many cases, low probability, rare extreme events in the early period become the norm in the latter period. These observed changes can be explained using a ‘pushing and triggering’ concept, representing interplay between external forcing and internal variability: long-term warming destabilizes the climate system and ‘pushes’ it to a new state, allowing subsequent variability associated with large-scale atmosphere–ocean–ice interactions and synoptic systems to ‘trigger’ extreme events over different timescales. Ongoing anthropogenic warming is expected to further increase the frequency and magnitude of extremes, such that simulated probabilities of 1.5 standard deviation events increase by 72.6% for atmospheric heat waves, 68.7% for Atlantic layer warm events and 93.3% for Greenland Ice Sheet melt rate between historic (1984–2014) and future (2069–2099) periods under a very high emission scenario. Future research should prioritize the development of physically based metrics, enhance high-resolution observation and modelling capabilities and improve understanding of multiscale Arctic climate drivers. Rare and extreme climate events have increasingly occurred in the Arctic since ~2000. This Review outlines the observed and projected changes in atmospheric, oceanic and cryospheric extremes and explains their increasing occurrence through a ‘pushing and triggering’ framework.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"6 11","pages":"691-711"},"PeriodicalIF":0.0,"publicationDate":"2025-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145450126","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}
