However, how this Mediterranean–monsoon teleconnection will respond to global warming remains poorly understood. Here we investigate the future evolution of the South Asian summer monsoon’s remote influence on Mediterranean summer climate under global warming using large ensemble simulations under a high-emission scenario. The monsoon influence on Mediterranean summer circulation weakens substantially under global warming, with the ensemble mean of correlation coefficient decreasing from 0.41 (P < 0.001) to near zero. This weakening results from the westward expansion of the monsoon-induced zonal thermal structure associated with elevated monsoon convection and a reduction in meridional wind anomalies through local dynamical feedbacks. The weakened monsoon-induced subsidence response further reduces the monsoon-related Mediterranean summer precipitation variability, with explained variance decreasing from 14.2% to 5.1%. Our results suggest that global warming will weaken the interannual coupling between the South Asian summer monsoon and Mediterranean summer climate, emphasizing the role of changing atmospheric dynamics in reshaping large-scale climate teleconnections. A warming climate may weaken the influence of the South Asian monsoon on Mediterranean summers, as shifting heat and wind patterns reduce its impact on regional weather, according to climate model projections under a high-emissions scenario.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"19 10","pages":"1225-1232"},"PeriodicalIF":20.6,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149022075","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}

Such a layer would have major implications for the thermal and chemical evolution of Mars, but its origin remains poorly constrained because experimental data on iron-rich Martian melts at deep-mantle conditions remain scarce. Here we use in situ ultrasonic interferometry combined with X-ray imaging and diffraction to determine the melting phase relations, ultrasonic response and chemical compositions of co-existing melts and solids under conditions relevant to the Martian core–mantle boundary. Our experiments constrain a Martian mantle solidus about 100 K lower than previous estimates. We show that incipient melting rapidly weakens the elastic response, reducing wave speeds and modifying the ultrasonic signal character. Melts generated slightly above the solidus at 18–19 GPa, equivalent to a depth of approximately 1,550 km, are strongly enriched in iron (Fe# of 0.5) and reach densities comparable to or greater than surrounding solids, implying neutral to negative buoyancy. The combination of high melt density and low wetting angles favours the formation of an interconnected dense melt layer near the core–mantle boundary from a moderately FeO-rich Martian mantle without necessarily requiring overturn of an extremely Fe-enriched primordial reservoir and remains compatible with proposed thermal models.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"38 1","pages":""},"PeriodicalIF":18.3,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149022077","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 investigate daily changes in jet strength, tilt and latitudinal extent from 1725 to 2100 using pressure data from four European stations alongside climate model simulations. These indices explain about 40% of day-to-day temperature variability in Western Europe year-round. Weather extremes—including heat waves, cold spells, heavy precipitation and windstorms—are closely linked to the jet stream, and the indices also capture signals of sudden stratospheric warmings and major solar storms. Since the pre-industrial period, the jet has strengthened by 0.13 standard deviations and shifted poleward during the cold season. Future projections indicate continued strengthening in winter, while extremes in the indices become less frequent, suggesting a potential reduction in some types of weather extremes. Since 1725, weather extremes in Western Europe have been closely linked to the Atlantic–European jet stream, which is projected to strengthen by 2100 while becoming less extreme, according to daily sea-level pressure records and climate model simulations.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"19 10","pages":"1182-1189"},"PeriodicalIF":20.6,"publicationDate":"2026-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41561-026-02069-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148933458","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 interface topography, or roughness, is widely thought to be an important factor, yet how roughness influences earthquake magnitude is still debated. This debate persists because, generally, studies are limited to individual subduction margins, proxies for roughness are used rather than direct measurements and historical earthquake records are short. Here we show by analysing data from 15 subduction zones globally that there is no relationship between any interface roughness parameter we derive from observations and a proxy for maximum earthquake magnitude. Specifically, for each margin, we use seismic reflection profiles of the plate boundary fault to quantify its roughness at 1–10 km scales, and in the same locations we test whether geodetically constrained interface coupling is an indicator of earthquake potential in lieu of a longer historical record. This analysis shows a strong positive relationship between earthquake magnitude and interface coupling, and that roughness parameters are unrelated to maximum magnitude or coupling. Our findings challenge the prevailing hypothesis that subduction interface roughness is a predominant control on its seismogenic behaviour and imply that interface roughness measured over length scales up to 10 km should not be used to assess a margin’s seismic hazard. An analysis of data from 15 subduction zones finds no relationship between metrics of the topography of the plate interface and the largest earthquake it can generate, implying that this topography is not a key control on subduction zone seismicity.","PeriodicalId":19053,"journal":{"name":"Nature Geoscience","volume":"19 10","pages":"1233-1240"},"PeriodicalIF":20.6,"publicationDate":"2026-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41561-026-02093-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148933460","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}
