Here we use temporal autocorrelation of satellite-derived vegetation greenness to quantify ecosystem resilience following 142,444 severe drought events across tropical forests from 2003 to 2022. We show that resilience declined in 68.8% of areas after droughts, particularly in dry environments, whereas 20.3% of areas with increased resilience were located in moist tropical forests. More intense and prolonged droughts led to a pronounced decline in resilience. Mean annual precipitation was identified as the most important regulator influencing resilience changes after drought, while soil phosphorus was the most consistent regulator across forest biomes, exhibiting widespread mitigating effects on resilience loss. Along decreasing precipitation gradients, the mitigating effect of soil phosphorus on post-drought resilience loss intensified. These findings provide insights into how tropical forests respond to drought and offer practical guidance for region-specific, adaptive forest management under a changing climate. Drought disturbances are reducing the recovery capacity of tropical forests, especially in drier conditions, but soil phosphorus can mitigate this impact, according to a satellite-based analysis of ecosystem resilience.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"19 10","pages":"1241-1247"},"PeriodicalIF":20.6,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148895442","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, these vertically compound soil moisture droughts, in which every soil layer suffers simultaneous water deficits, have been largely ignored because previous monitoring and risk assessments relied on entire-profile mean soil moisture. Here we identify vertically (0–100 cm) compound droughts worldwide during warm seasons of 1981–2020 using multilayer soil moisture products. Their annual duration and ratio have increased across more than half of global lands over the past four decades, with pronounced hotspots in southwestern North America, South America, Africa, mid-latitude Eurasia, southeastern Asia and Australia. Vertically compound droughts cause substantial declines in ecosystem productivity, particularly in forests and croplands, threatening carbon sink stability and food security. By contrast, diagnosing drought solely from entire-profile averages causes an overestimation of vertically compound drought duration by about 128.3% but an underestimation of associated ecosystem losses by about 27.8%. These projections and systematic biases highlight the urgency of developing multilayer monitoring, mitigation and adaptation strategies for vertically compound droughts. Vertically compound soil moisture droughts—when all soil layers are depleted—have intensified worldwide, driving sharper ecosystem losses than single-layer droughts, according to global analyses of multilayer soil moisture.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"19 10","pages":"1205-1212"},"PeriodicalIF":20.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41561-026-02083-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148899512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, observations of the Martian atmosphere challenge this picture. The mixing ratios of dust and gas species (H2O, CO, Ar) show large planetary-scale inhomogeneities, yet the mechanism causing this has been difficult to define. Here we investigate particle transport in the Martian atmosphere using a Lagrangian tracking method based on reanalysis data. We find that the coherent structure of the single-cell Hadley circulation on Mars can produce a distinct material transport pattern. Dynamical barriers prevent material mixing between the inside and outside of the Hadley cell and allow pole-to-pole teleconnection. Dimensional analysis indicates this is caused by the combined effect of rapid planetary rotation and the thin atmosphere of Mars. The dominance of the mean circulation over the eddy transport gives rise to this unique transport regime, which is fundamentally distinct from those on Earth and Venus. This finding challenges the conventional view of material mixing from planetary-scale circulations, suggesting planetary atmospheric dynamics can confine materials and restrict redistribution. Single-cell Hadley circulation drives pole-to-pole connection on Mars but also inhibits material mixing between the cell’s interior and exterior, according to a study of the Martian atmosphere using Lagrangian particle tracking.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"19 10","pages":"1218-1224"},"PeriodicalIF":20.6,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148899596","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}

Yet their effects on local surface climate remain poorly quantified. Here we combine Landsat-derived summer land-surface temperature estimates with a Europe-wide disturbance record to assess how disturbance attributes and forest properties shape post-disturbance warming and thermal recovery. We find that disturbed forests exhibit higher summer land-surface temperatures, with warming of 1.70 °C relative to adjacent undisturbed forests located 100 to 500 m from disturbance edges. Post-disturbance temperature anomalies are driven primarily by vegetation and canopy-structure loss, with disturbance severity emerging as the strongest predictor. Forest properties further modulate warming, with needleleaf forests warming more strongly than broadleaf forests and plantations more than natural forests. Thermal recovery trajectories shows that more than 82% of disturbance-induced warming dissipates within ten years. Together, these findings identify key biophysical controls on disturbance-driven surface warming across Europe and highlight the potential of forest-management strategies to limit its magnitude, while balancing thermal, ecological and silvicultural goals. Forest disturbances drive substantial surface warming across Europe, with magnitude and recovery shaped by disturbance severity, size and forest characteristics, as inferred from combining satellite-derived land-surface temperature estimates with continent-wide disturbance data.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"19 9","pages":"1082-1090"},"PeriodicalIF":20.6,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853686","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}

While higher concentrations of non-black-carbon components surrounding black-carbon particles (known as coatings) can enhance radiative effects, accurately representing and validating these effects at high spatiotemporal resolution remain computationally challenging. Here, we synthesize a decade (2012–2021) of intensive ground-based and aircraft-based global in situ observations of single-particle black carbon and its coatings to quantify how coating thickness varies across urban and wildfire biomass-burning sources and how this variability influences black-carbon radiative forcing. We find that coatings increase the global top-of-atmosphere radiative effect of black carbon from 0.20 ± 0.25 W m−2 to 0.30 ± 0.42 W m−2, with an additional 0.065 ± 0.15 W m−2 attributable to black carbon in cloud liquid water. Thicker coatings make the radiative effects of biomass-burning black carbon two to three times stronger than the radiative effects of urban black carbon. This enhanced forcing may persist into the future, as particulate-matter concentrations are projected to follow divergent trajectories over the next half century. Our results suggest that black carbon exerts stronger warming effects in more polluted environments, highlighting the importance of jointly controlling black-carbon and particulate-matter emissions. Layers of particulate matter that accumulate on black carbon can boost warming by raising top-of-atmosphere forcing, with biomass-burning particles two to three times more impactful than urban ones, based on a model and global observations.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"19 10","pages":"1174-1181"},"PeriodicalIF":20.6,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853494","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}
