However, there is a limited understanding of spatial variations in the carbon dioxide (CO₂) fertilization effect (CFE) on these systems. Here, using the MODIS normalized difference vegetation index (NDVI), meteorological and CO₂ gridded datasets from 2000 to 2022, we found that vegetation greenness showed an increasing trend in the Tibetan Plateau (TP), with a larger increasing trend in the north. Greenness changes were significantly positive correlated with temperature and precipitation in 10.13 % and 16.53 % of the TP respectively, mainly in center. In a smaller region in the southern TP, temperature and precipitation showed significant negative correlations, accounting for 2.22 % and 8.27 % of the TP respectively. Moreover, there were significantly positive relationships between greenness and CO₂ concentration in 23.69 % of the TP, suggesting that the CFE was more prevalent than the impacts of temperature and precipitation. In particular, the CFE was significant in 48.04 % of the alpine desert steppe. The spatial relationship between CFE and precipitation followed a unimodal pattern, peaking at an annual precipitation of 156 mm, and the CFE approached zero when precipitation exceeded 730 mm. In contrast, the relationship of CFE with temperature exhibited a bimodal pattern, peaking at mean annual temperatures of 2.1 °C and 12.7 °C. Their complex relationships should be closely related to the response of plant physiological processes to temperature and water. This study improved our understanding of vegetation response to global change in water-limited alpine ecosystems.</div></div>","PeriodicalId":55089,"journal":{"name":"Global and Planetary Change","volume":"252 ","pages":"Article 104839"},"PeriodicalIF":4.0,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143882903","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}

In large river basins, the complex topography and varied climate within the basin make it challenging to quantitatively characterize the weathering features in the river basin. To study the weathering characteristics in large river basin, which is the Changjiang River Basin in this case, we defined the “High Slope Area (HSA)” as a region within each major tributary with slopes greater than 5 degrees. We analyzed various landforms and environmental parameters within the HSA in relation to the Chemical Index of Alteration (CIA) of river sediments. Our findings revealed a stronger correlation between the CIA of river sediments and the overall parameters within the HSA than the environmental parameters of the entire basin in general. Notably, a negative correlation exists between CIA and slope and elevation in the HSA, suggesting an inhibition of physical erosion on chemical weathering. On the contrary, the temperature and precipitation in the HSA exert a positive impact on sediment CIA. Under high precipitation regimes, the enhancement effect of precipitation on chemical weathering may exhibit attenuation. However, this inference currently lacks statistical significance and requires validation through additional datasets. This study significantly enhances our understanding of the factors controlling CIA in river sediments and provides valuable insights into quantifying continental weathering at the large basin scale.</div></div>","PeriodicalId":55089,"journal":{"name":"Global and Planetary Change","volume":"251 ","pages":"Article 104841"},"PeriodicalIF":4.0,"publicationDate":"2025-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143859732","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}

These geodynamic conditions lead to the formation of crustal transfer zones associated with significant strain partitioning. A key area to study such mechanisms is the transition between the Dinarides and Hellenides mountain chains in southeastern Europe, affected by the indentation of the Adriatic continental microplate. Similar to other Mediterranean orogens, the slab roll-back was accompanied by a migration of the orogenic shortening towards the foreland and a coeval back-arc extension that reactivated inherited orogenic nappe contacts. Along the strike of the orogen, the Dinarides slab detached during Oligocene – early Miocene times, while the Hellenides subduction continued its evolution up to the present day. The transfer of deformation takes place along various structures in the transition zone between the Dinarides and Hellenides, from areas that underwent significant Adriatic indentation following the detachment of the subducted slab to the others where the retreat of the Aegean slab continues. We have performed a field kinematic and microstructural study in the less understood segment of the Dinarides-Hellenides transition in northern Montenegro to analyse the mechanism of strain partitioning in the Dinarides nappe stack related to along-strike changes in slab kinematics. The results demonstrate that the previously defined scissor-mechanism of extensional deformation in the neighbouring Hellenides is transferred dominantly to a newly documented large offset shear zone. This structure accommodates orogen-perpendicular extension by reactivating inherited Cretaceous – Paleocene nappe contacts, forming a major post-Eocene detachment and extensional klippens, which are cross-cut by late-stage brittle normal faults. When combined with the known structure of the neighbouring Hellenides, these results infer that the Oligocene – early Miocene slab-detachment of the Dinarides orogenic segment was accommodated at crustal levels by generalised bi-directional extension, exhuming mid-crustal levels in the footwall of major structures and accommodating the transition from Adriatic indentation to the continued subduction recorded by the Hellenides.</div></div>","PeriodicalId":55089,"journal":{"name":"Global and Planetary Change","volume":"252 ","pages":"Article 104837"},"PeriodicalIF":4.0,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860416","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}

In recent years, the reduction in wind speed may have mitigated drought stress induced by rising temperatures, further weakening dust emissions. In this study, we present changes in global dust aerosol optical thickness (DOT) alongside variations in dust events, in response to alterations in desert regions associated with climate change. We find that global near-surface dust events (excluding Europe) declined annually from 2000 to 2023. Concurrently, the DOT in desert regions, specifically in the eastern Thar Desert, the Sahara Desert, and the Badain Jaran Desert, also decreased annually. This decline is primarily attributed to the reduced intensity of sand-moving wind regime in these areas, with drift potential (DP) decreasing by 37 %, 10 %, and 8 %, respectively. Additionally, dust activity has also diminished to varying degrees in parts of North Africa, Northeast Asia, South America, and Southern Africa. Finally, we project future changes in aeolian dust conditions in desert areas over the next three decades under the SSP 2–4.5 and SSP 5–8.5 scenarios. Under future simulation scenarios, the declining trend in DP is projected to intensify over the next three decades, with significant regional disparities. Notably, under the high emission scenario, the median DP of global deserts is projected to decrease by 1.1 m³ s⁻³ compared to the median under the medium emission scenario, with the reductions primarily occurring in the southern Sahara Desert and northeastern Australian deserts. Conversely, significant increases in DP are projected under high-emission scenarios in the Arabian Desert, Taklamakan Desert, and Gobi Desert. These changes are anticipated to heighten the risk of global dust events, which may be associated with large-scale ocean-atmosphere oscillations. Such projected changes will impact dune erosion and dust emissions, influencing urban and rural planning in desert regions and posing potential risks to human health.</div></div>","PeriodicalId":55089,"journal":{"name":"Global and Planetary Change","volume":"252 ","pages":"Article 104844"},"PeriodicalIF":4.0,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143865129","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}

Sedimentary structures imaged with seismic reflection data in Princess Elizabeth Trough, the deep water gateway between the Kerguelen Plateau and Prydz Bay, are interpreted regarding direction and intensity of pathways of deep/bottom water masses transported in gyres, eddies, and boundary currents to contribute to the knowledge on potential locations of carbon subsidence.

This has been compared with published reconstructions of warming/cooling trends of the global climate.
