Here, we review three decades of scientific literature (<span><math><mo>∼</mo></math></span>1995 to early 2024) to assess to what degree observational records from the European Alps – as the region with the most comprehensive records – reveal these changes. We do this for the processes that are most common in this region, namely rockfall, rock avalanches, debris flows, ice avalanches, and snow avalanches. The systematic literature search and review yielded 335 publications, of which we omitted publications that did not focus primarily on observational records. The remaining 103 publications used observations from over 100 sites and 30 inventories to investigate the connection between climate change and mass movements. About one third of the relevant studies found a measurable impact of climate change on the investigated alpine mass movement processes (with the exception of large rock avalanches). The clearest climate-controlled trends are (i) increased rockfall frequency in high-alpine areas due to higher temperatures, (ii) fewer and smaller snow avalanches due to scarcer snow conditions at low and mid elevations, and (iii) a shift towards avalanches with more wet snow and fewer powder clouds. While there is (iv) despite a clear increase in debris-flow triggering precipitation, debris-flow activity has not been found to uniformly increase, though there is some evidence for increasing activity above treeline and at locations without historical precedence. The trends for (v) ice avalanches are spatially very variable with no clear direction. Ice temperatures are measurably increasing, but – despite a theoretical expectation – this has not impacted ice avalanche activity to date. The reviewed literature also reveals that quantifying the impact of climate change on these mass movements remains difficult in part due to the complexities of the natural system, but also because of limitations in the available datasets, confounding effects, and existing statistical processing techniques. Better assessments could be achieved if we would more broadly support the compilation and maintenance of large standardized data catalogs, bring together various dispersed datasets (in said catalogs), including from social and citizen science projects, invest in long-term natural observatories, and develop suitable processing techniques. Better observations will additionally support the development and performance of process-based models. If we can advance natural hazard research on these fronts, more quantitative predictions of future change are well within our reach.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"258 ","pages":"Article 104886"},"PeriodicalIF":10.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142651416","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 emission, transport, and deposition of dust interacts with and connects Critical Zone processes at all spatial and temporal scales. Landscape properties, land use, and climatic factors influence the wind erosion of soil and nutrient loss, which alters the long-term ecological dynamics at erosional locations. Once in the atmosphere, dust particles influence the amount of solar radiation reaching Earth, and interact with longwave (terrestrial) radiation, with cascading effects on the climate system. Finally, the wet and dry deposition of particles influences ecosystem structure, composition, and function over both short and long-term scales. Tracking dust particles from source to sink relies on monitoring and measurement of the geochemical composition and size distribution of the particles, space-borne and ground-based remote sensing, and dust modeling. Dust is linked to human systems via land use and policies that contribute to dust emissions and the health-related consequences of particulate loads and composition. Despite the significant influence dust has in shaping coupled natural-human systems, it has not been considered a key component of the Critical Zone.

This model is inconsistent with the crustal thickness variation confirmed by seismic tomography profiles and Moho map (Araujo et al., 2021), unreliable REE chondrite-normalized flat patterns (Kerr, 2014), absent of HIMU Pb isotope anomaly and lack of W, He or Ne isotope information indicative of primordial mantle. Along the Coastal Ranges, Jaillard discusses the NE-oriented San Lorenzo Arc (SLA) within the context of a back-arc basin, incorporating the Chongón Colonche High (CCH) as a remnant arc orthogonal to the margin since its emplacement. Contrarily, he overlooks the widespread Cretaceous olistolith outcrops representing the cryptic and vanished Paleocene suture zone, unlike the undeformed Santa Elena Formation. The occurrence of CR lower continental crust, inferred from lower than 7 Km/s <em>sec</em> V_p velocity, decisively challenges the CCOP paradigm. To the east, while Jaillard describes west-vergent contractional deformation and the prowedge foredeep flysch, he geologically thickens the Western Cordillera by rooting thrusting near the crustal-mantle boundary, including the slender Guaranda Terrane (Totoras amphibolite). This is inconsistent with the 85 Ma crystallization age of HT metamorphism predating the collision event, further questioning the CCOP model. Additionally, Jaillard disregards the Pallatanga suture melange and the adakite Pujilí Granite obstructing subduction, which shifted westward post-collision, forming the Rio Cala intraoceanic arc synchronous with flysch foredeep deposition (Vallejo, 2007) and providing the stresses for contractional deformation. Along the foreland basin, Jaillard's distortion from lithostratigraphic to chronostratigraphic isopach maps impedes recognition of the molasse source, provenance, and deposition, coeval with the EC development. The Abitagua Granite, adjacent to the giant Pungarayacu heavy oil field, necessitates continuity of Cretaceous source rocks under the EC, also functioning as a detachment. The high gravitational potential energy achieved during strong collision dissipates through extensional gravitational collapse, modulating eastward as toe-thrust imbrication and utilizing the Cretaceous detachment to form the Eastern Cordillera retrowedge concurrently with WC contractional deformation, resulting in a bivergent fold and thrust belt.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"258 ","pages":"Article 104939"},"PeriodicalIF":10.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142651417","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}

Caves in limestone develop very fast (∼10&lt;sup&gt;4&lt;/sup&gt; years) when conditions for bedrock solution are optimal, and many contain alluvium deposited by allogenic sinking streams, preserving the sediment thereafter for millions of years. Cave networks display a vertical succession of sub-horizontal passages which indicate past positions of the water table, with the stream in- and outlet caves indicating the former elevation of the adjacent valley floor. Abandoned cave levels are expected to multiply as valley incision increases local relief (descending speleogenesis), but sediment aggradation or glacier ice accumulation may also raise the local base level and flood older caves or generate new ones (ascending speleogenesis). Establishing the age of alluvial sediment hosted by caves relies on burial dating of quartz-rich clasts using two terrestrial cosmogenic nuclides (TCNs) – commonly &lt;sup&gt;26&lt;/sup&gt;Al and &lt;sup&gt;10&lt;/sup&gt;Be – measured in the same sample. Systematic examination of age–elevation data patterns in the existing literature reveals situations ranging from intuitively consistent valley incision histories to counter-intuitive age inversions and other anomalies. Here those anomalies are analyzed and classified in order to establish the extent to which the corresponding inconsistencies are avoidable, thereby providing a methodical catalogue of foreseeable difficulties and pitfalls. Three domains of uncertainty are emphasized. The first relates to karst processes: cave network geometry, cave passage response to vadose and phreatic processes, and diachronous links between cavity age and sediment. The multiple pathways of speleogenesis are reviewed. They highlight ambiguities behind the concept of ‘cave level’, which, as a proxy for base-level paleoelevations, may be less precise than subaerial information provided by fluvial fill or strath terraces. The second source of uncertainty lies in the chronological information provided by the alluvium. Sediment dynamics in subterranean karst generate complicated stratigraphic configurations, with opportunities for postdepositional sediment reworking within or between cave levels. Furthermore, a TCN burial age is valid for a population of quartz grains but not necessarily for the entire stratigraphic sequence containing them nor for the cave that contains it. The third source of uncertainty lies in the burial dating method itself, because &lt;sup&gt;26&lt;/sup&gt;Al and &lt;sup&gt;10&lt;/sup&gt;Be nuclide inventories cannot unequivocally document whether older burial events might have occurred prior to final burial in the cave.
