Most of large instrumentally-recorded earthquakes have occurred on faults lacking well-documented histories of past events. The 2023 Mw 7.8-7.7 Kahramanmaraş earthquake doublet is exceptional as it ruptured multiple segments of the East Anatolian Fault (EAF) system, where historical records of devastating earthquakes span over two millennia. Here, we use historical earthquake records, measurements of interseismic deformation, and published slip models of the 2023 events to evaluate the recurrence patterns of large earthquakes. We compare slip deficit that accrued on each fault segment since the respective penultimate events to the average coseismic slip of the 2023 doublet. We find that the coseismic slip equaled to or exceeded the accumulated slip deficit, suggesting that the slip-predictable recurrence model applies as a lower bound on strain release during the Kahramanmaraş earthquakes.","PeriodicalId":10530,"journal":{"name":"Communications Earth & Environment","volume":"6 1","pages":"80"},"PeriodicalIF":8.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11798867/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143381748","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}

Here, using the most comprehensive statistics of 18 industrial productions and 2 product uses during 2000–2020, we find China’s IPPU CO2 emissions reached 1628 million metric tons (Mt) in 2020, which were 3.0%–6.5% higher than estimates from other studies. Compared to previous studies identifying main driving factors of combined CO2 emissions from fossil-fuel and IPPU, we show that the main indicators of China’s IPPU emissions growth was the per capita construction area during 2000–2020 (94%). We construct a comprehensive provincial IPPU emission inventory based on the up-to-date provincial-level statistics, identifying the key mitigation regions in China. This study reveals China’s IPPU emissions are the non-ignorable factor in China’s carbon mitigation. China’s carbon dioxide emissions from industrial processes and product use were 1628 million metric tons in 2020, and the main driver of the emission growth over the past two decades is per capita construction area, according to an analysis that uses industrial production and process data.","PeriodicalId":10530,"journal":{"name":"Communications Earth & Environment","volume":" ","pages":"1-11"},"PeriodicalIF":8.1,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43247-024-01951-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142906126","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}

While conservation aspects are increasingly emphasized in these projects, the rigor of biodiversity co-benefit verification has been highly variable. Recent advances in biodiversity monitoring based on shed DNA in the environment (eDNA) offer promise for improving effectiveness, standardization, and transparency. Here we analyze 129 forest carbon projects and 396 peer-reviewed studies to identify how biodiversity co-benefits are currently verified within forest carbon markets, and to evaluate the potential of eDNA for tracking biodiversity change. Our analysis revealed that eDNA studies focused more on smaller organisms (microbes and invertebrates) and on temperate ecosystems compared with biodiversity-focused forest carbon projects. Efforts to align these two worlds via investments into broadening the geographic and taxonomic scope could allow greater adoption and increased accountability in biodiversity monitoring within forest carbon markets (i.e. standardized, auditable biodiversity data trails). Adapting advancements in eDNA technology to the biodiversity monitoring needs of nature-based initiatives will aid countries and organizations striving to meet global conservation commitments. Environmental DNA studies focus more on microbes, invertebrates, and temperate ecosystems, compared to biodiversity-focused forest carbon projects, and both areas need to align to facilitate improved biodiversity monitoring in the forest carbon market, according to the three-phase systematic analysis.","PeriodicalId":10530,"journal":{"name":"Communications Earth & Environment","volume":" ","pages":"1-10"},"PeriodicalIF":8.1,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43247-024-01970-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142906132","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}

The threats from rocket launches are potentially associated with biomes, coordinates, and proximity to oceans. In particular, threatened terrestrial species in Tropical and Subtropical Moist Broadleaf Forests are more vulnerable to these risks compared to species in other biomes. Without strategic planning, the continued growth of rocket launches could create conflicts between technological development and conservation efforts, undermining the achievement of UN Biodiversity Goals.

While surface intensification of temperature seasonality has been widely examined, changes beneath the ocean surface remain unknown. Here we analyze multiple ocean temperature datasets, revealing a robust, substantial weakening of subsurface seasonality by 5.7 ± 1.8% below the mixed layer in extratropical oceans since the 1980s. Using a hierarchy of climate models and an idealized diffusive model, we attribute this weakening to increased ocean heat uptake driven by rising greenhouse gases. This process strengthens upper ocean stratification, suppresses vertical mixing, and limits heat penetration into deeper ocean layers, resulting in a more quiescent subsurface ocean with reduced seasonal variability. Our findings highlight a new fingerprint of anthropogenic influence on subsurface ocean seasonality, with important implications for ocean biogeochemical processes and marine ecosystems. Since the 1980s, subsurface temperature seasonality in extratropical oceans has decreased by 5.7 ± 1.8% below the mixed layer due to increased heat uptake from greenhouse gases, strengthening upper ocean stratification, and limiting heat penetration into deeper layers, according to analysis of a hierarchy of climate models and an idealized diffusive model.","PeriodicalId":10530,"journal":{"name":"Communications Earth & Environment","volume":" ","pages":"1-8"},"PeriodicalIF":8.1,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43247-024-01986-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142906142","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}

This is particularly true in climate change hotspots such as the Mediterranean region, where spatiotemporal compounding of extreme phenomena is becoming the norm. In the framework of a new spatiotemporal approach to heatwave detection, which tracks the evolution of the phenomena throughout their life cycle, the concurrence of marine and atmospheric heatwaves is investigated in this study. Concurrency of both phenomena in time and space shows a relevant impact on the intensity of the marine heatwaves, while no relevant changes are observed in atmospheric heat waves. Therefore, we demonstrate that intensification in extreme temperature events is accompanied by the added local intensification effect of marine heatwaves when concurring with atmospheric heatwaves, especially in recent years. Climate change has increased the frequency and intensity of temperature extremes, especially in the Mediterranean, where the concurrence of marine and atmospheric heatwaves amplifies marine heatwave intensity, while atmospheric heatwaves show no significant changes, according to a spatiotemporal approach to heatwave detection.","PeriodicalId":10530,"journal":{"name":"Communications Earth & Environment","volume":" ","pages":"1-13"},"PeriodicalIF":8.1,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43247-024-01982-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142906158","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}

Here we use principal component analysis to derive a stand structural indicator (SSI) index based on four structural metrics derived from GEDI covering tropical forests and upscale the GEDI footprint-level SSI to a spatially continuous distribution using Sentinel-1&2 imagery. The majority of high SSI values representing higher forest height, density and diversity of canopy height, is found for all tropical forest areas in moist regions, natural forests, and regions with less fire activity. We show that SSI is positively correlated with primary productivity and that the sensitivity of productivity to SSI is larger in natural forests than in managed forests. Our results highlight synthesized stand structure information to support sustainable forest management and conservation. A strong link between stand structure and primary productivity is pervasively found in forests across the pantropical region, according to an analysis of GEDI lidar data and Sentinel remote sensing imagery.","PeriodicalId":10530,"journal":{"name":"Communications Earth & Environment","volume":" ","pages":"1-9"},"PeriodicalIF":8.1,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43247-024-01984-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142906154","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}

Contrastingly, biosamplers and biofilms exposed to the mine environment contained aerobic Sphingomonas taxa. δ13C values of phospholipid fatty acids and putative functional predictions derived from 16S rRNA gene profiles, imply Candidatus Frackibacter may use carbon derived from ancient carbon-rich layers common in these systems.
