Whereas tidal wetlands at the land–ocean interface are included in global C budgets, lake littoral zones are currently not accounted for, despite the total shoreline of lakes being estimated at four times longer than that of the global ocean. Here we quantify the littoral net atmospheric C sink using mass balance and a model of C export from the littoral to the pelagic zone. We argue that ignoring littoral C turnover in lakes potentially results in biased estimates of continental C cycling. In our global estimate, we show that the estimated global C balance of lakes may reverse from a net C source to a net C sink (that is, net C burial > net C outgassing). In addition, a large part of the C outgassed in the pelagic might originate from the littoral, implying that previous estimates of terrestrial C inputs to inland waters were too high. We argue that quantifying and modelling lake littoral C fluxes are essential to more accurately estimate the feedback between the continents and climate.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"12 1","pages":""},"PeriodicalIF":18.3,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144769908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the magnitude of rain-induced carbon emissions remains unclear globally. Here we quantify the impact of rain-pulse events on the carbon balance of global drylands and characterize their spatiotemporal controls. Using eddy-covariance observations of carbon, water and energy fluxes from 34 dryland sites worldwide, we produce an inventory of over 1,800 manually identified rain-induced CO2 pulse events. Based on this inventory, a machine learning algorithm is developed to automatically detect rain-induced CO2 pulse events. Our findings show that existing partitioning methods underestimate ecosystem respiration and photosynthesis by up to 30% during rain-pulse events, which annually contribute 16.9 ± 2.8% of ecosystem respiration and 9.6 ± 2.2% of net ecosystem productivity. We show that the carbon loss intensity correlates most strongly with annual productivity, aridity and soil pH. Finally, we identify a universal decay rate of rain-induced CO2 pulses and use it to bias-correct respiration estimates. Our research highlights the importance of rain-induced carbon emissions for the carbon balance of global drylands and suggests that ecosystem models may largely underrepresent the influence of rain pulses on the carbon cycle of drylands.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"142 1","pages":""},"PeriodicalIF":18.3,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent global-scale studies have suggested that ecosystem restoration could offset a substantial fraction of human carbon emissions since the Industrial Revolution. However, global carbon sequestration potential remains uncertain due to the tree-centric view of some models and difficulties in modelling restoration across different ecosystem types. Here we applied a model-based prediction workflow to estimate the carbon capture potential of restoring forest, shrubland, grassland and wetland ecosystems until 2100. We found that the maximum sequestration potential is 96.9 Gt of carbon, equivalent to 17.6% of the anthropogenic emissions to date, or 3.7–12.0% if taking into account future emissions until 2100. Our results suggest that ecosystem restoration has limited potential for climate change mitigation even if orchestrated with a pervasive shift towards sustainable, low-emissions economies globally. In addition, if we plan restoration targets to match future climatic conditions and consider state transitions of currently natural ecosystems due to climate change, the potential for natural climate solutions related to ecosystem restoration is close to zero. Therefore, we recommend that ecosystem restoration is pursued primarily for restoring biodiversity, supporting livelihoods and resilience of ecosystem services, as the climate mitigation potential will vary depending on the state transitions that occur between vegetation types.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"149 1","pages":""},"PeriodicalIF":18.3,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The past 20 kyr are a prime target for model validation, as boundary conditions are reasonably well known, and the AMOC and climate experienced dramatic changes during this period. Here we present eight subsurface Atlantic temperature reconstructions based on benthic foraminiferal magnesium-to-lithium ratios, and compare the timing and amplitude of reconstructed changes with those in two coupled climate model simulations. We show that compared with the last glaciation and the past 8 kyr, the shallow (~500–1,100 m water depth) tropical North Atlantic was anomalously warm during most of the last deglaciation and early Holocene, which the models suggest is due to a relatively weak AMOC that reduced advection and allowed heat to accumulate. Our temperature reconstructions imply that the AMOC strengthened ~14.7 kyr ago and during the early Holocene (from ~12 to 8 kyr ago), suggesting that enhanced northward heat transport contributed to Northern Hemisphere warming and deglacial melting at these times. The transient model simulations predict features of temperature reconstruction with varying success, possibly because deglacial and Holocene AMOC strength are poorly constrained, and not accurately simulated.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"216 1","pages":""},"PeriodicalIF":18.3,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Observations and theory indicate that meltwater generated at the ice sheet surface can drain to its bed, where it flows relatively unhindered to the ocean. This understanding of water movement within and beneath ice sheets underpins the theoretical models that are used to make projections of ice sheet change. Here we present evidence of a destructive mode of meltwater drainage in Greenland. Using multiple satellite sources, we show that a 90-million-cubic-metre subglacial flood forced its way upwards from the bed, fracturing the ice sheet, and bursting through the surface. This phenomenon was triggered by the rapid drainage of a subglacial lake and occurred in a region where the ice bed was predicted to be frozen. The resulting flood caused a rapid deceleration of the downstream marine-terminating glacier. Our observations reveal a complex, bi-directional coupling between the ice sheet’s surface and basal hydrological systems and demonstrate that extreme hydrological forcing may occur in regions of predicted cold-based ice. Such processes can impact the ice sheet’s dynamics and structural integrity but are not currently considered in ice sheet models.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"111 1","pages":""},"PeriodicalIF":18.3,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144737016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we report a consistent mismatch between plant and soil microbial phenology under climate warming, on the basis of 1,032 globally distributed observations of phenological shifts in plant and/or soil microbial respiration in response to experimental warming. Advances in spring phenology and delays in autumn phenology are greater in soil microorganisms than in both plant shoots and roots, particularly under tall vegetation (for example, forests) compared with low vegetation (for example, grasslands). Furthermore, phenology shifts in soil microorganisms are greater in soils with high carbon-to-nitrogen ratios, such as those in boreal regions, than in those with lower ratios. Such phenological mismatches between plants and soil microorganisms could destabilize their temporal synchrony, decoupling above- and belowground processes, and ultimately degrading energy flow and ecosystem functioning under climate warming.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"23 1","pages":""},"PeriodicalIF":18.3,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144719573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

How inelastic strain localizes as fault systems mature and structurally develop is less well understood owing to the difficulty of measuring the complex, near-field and high-strain regions of coseismic surface ruptures. Here we use radar and optical images to measure the near-field surface displacement field and magnitude of off-fault inelastic strain from 16 historic strike-slip earthquakes that occurred on faults with cumulative displacements and fault slip rates that span almost three orders of magnitude. We show that inelastic shear deformation does localize as fault systems mature: the magnitude of off-fault inelastic strain is largest (34–67%) for fault systems with the lowest cumulative displacements (<3 km) and then rapidly decays to values that saturate around 13–19% for the most ‘mature’ fault systems with cumulative displacements exceeding ~20 km. We find that more localized coseismic ruptures host faster ruptures, generate fewer aftershocks and occur along geometrically simpler fault networks.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"14 1","pages":""},"PeriodicalIF":18.3,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
