Abstract Mechanisms underlying plant succession remain highly debated. A global quantification of the relative importance of species addition versus replacement is lacking due to the local scope of most studies. We quantified their role in the variation of plant communities colonizing the forelands of 46 retreating glaciers distributed worldwide, using both environmental DNA and traditional surveys. Both mechanisms concur in determining community changes over time but their relative importance varied over time along successions. Taxa addition predominated immediately after glacier retreat, as expected in harsh environments, while replacement became more important for late-successional communities. Those changes were aligned with total beta-diversity changes, which were larger between early successional communities than between late-successional communities (>50 years since glacier retreat). Despite the complexity of community assembly over plant succession, our global pattern suggests a generalized shift from the dominance of facilitation and/or stochastic processes in early successional communities to a predominance of competition later on.

La cordillère des Andes contient la cryosphère la plus diversifiée sur Terre, y compris de vastes zones couvertes de neige saisonnière, de nombreux glaciers tropicaux et extratropicaux et de nombreux reliefs de pergélisol montagneux. Ici, nous passons en revue quelques avancées récentes dans l'étude des principales composantes de la cryosphère dans les Andes, et discutons des changements observés dans la neige saisonnière et les masses de glace permanentes de cette région au cours des dernières décennies. Le libre accès et la disponibilité croissante des produits de télédétection ont considérablement amélioré notre compréhension de l'état actuel et des changements récents de la cryosphère andine, permettant un détail sans précédent dans leur identification et leur suivi à l'échelle locale et régionale. Les analyses des cartes de couverture neigeuse ont permis d'identifier les tendances saisonnières et les tendances à long terme de l'accumulation de neige pour la plupart des Andes, certains secteurs du centre du Chili et du centre-ouest de l'Argentine montrant une nette diminution des chutes de neige et de la persistance de la neige depuis 2010. Cette récente pénurie de neige de montagne a provoqué une sécheresse prolongée et sévère sans précédent dans les registres hydrologiques et climatologiques de cette région. En plus des données provenant des inventaires mondiaux des glaciers, des inventaires détaillés à l'échelle locale/régionale sont désormais également disponibles gratuitement, fournissant de nouvelles informations importantes pour les évaluations glaciologiques, hydrologiques et climatologiques dans différents secteurs des Andes. De nombreuses études largement basées sur des mesures sur le terrain et/ou des techniques de télédétection ont documenté le récent rétrécissement des glaciers dans les Andes. Cette perte de masse de glace observée a placé les glaciers andins parmi les plus grands contributeurs à l'élévation du niveau de la mer par unité de surface. D'autres études récentes se sont concentrées sur les glaciers rocheux, montrant que dans de vastes secteurs semi-arides des Andes, ces caractéristiques du pergélisol de montagne contiennent de grandes réserves d'eau douce et peuvent jouer un rôle crucial à mesure que le climat futur devient plus chaud et plus sec dans cette région. De nombreuses questions pertinentes restent cependant à étudier, notamment une meilleure estimation des volumes de glace à l'échelle locale et des évaluations détaillées de l'importance hydrologique des différentes composantes de la cryosphère dans les bassins fluviaux andins. La Cordillera de los Andes contiene la criosfera más diversa de la Tierra, incluidas extensas áreas cubiertas por nieve estacional, numerosos glaciares tropicales y extratropicales y muchos accidentes geográficos de permafrost de montaña. Aquí, revisamos algunos avances recientes en el estudio de los principales componentes de la criosfera en los Andes, y discutimos los cambios observados en la nieve estacional y las masas de hielo permanentes de esta región en las últimas décadas. El acceso abierto y la creciente disponibilidad de productos de teledetección ha producido una mejora sustancial en nuestra comprensión del estado actual y los cambios recientes de la criosfera andina, lo que permite un detalle sin precedentes en su identificación y monitoreo a escala local y regional. Los análisis de los mapas de la cubierta de nieve han permitido identificar patrones estacionales y tendencias a largo plazo en la acumulación de nieve para la mayor parte de los Andes, y algunos sectores en el centro de Chile y el centro-oeste de Argentina muestran una clara disminución de las nevadas y la persistencia de la nieve desde 2010. Esta reciente escasez de nieve de montaña ha provocado una prolongada y severa sequía que no tiene precedentes en los registros hidrológicos y climatológicos de esta región. Junto con los datos de los inventarios mundiales de glaciares, los inventarios detallados a escala local/regional ahora también están disponibles gratuitamente, proporcionando nueva información importante para las evaluaciones glaciológicas, hidrológicas y climatológicas en diferentes sectores de los Andes. Numerosos estudios basados en gran medida en mediciones de campo y/o técnicas de teledetección han documentado la reciente contracción de los glaciares en los Andes. Esta pérdida de masa de hielo observada ha colocado a los glaciares andinos entre los que más contribuyen al aumento del nivel del mar por unidad de área. Otros estudios recientes se han centrado en los glaciares de roca, lo que demuestra que en amplios sectores semiáridos de los Andes estas características de permafrost de montaña contienen grandes reservas de agua dulce y pueden desempeñar un papel crucial a medida que el clima futuro se vuelva más cálido y seco en esta región. Sin embargo, quedan por investigar muchas cuestiones relevantes, incluida una mejor estimación de los volúmenes de hielo a escala local y evaluaciones detalladas de la importancia hidrológica de los diferentes componentes de la criosfera en las cuencas fluviales andinas. The Andes Cordillera contains the most diverse cryosphere on Earth, including extensive areas covered by seasonal snow, numerous tropical and extratropical glaciers, and many mountain permafrost landforms. Here, we review some recent advances in the study of the main components of the cryosphere in the Andes, and discuss the changes observed in the seasonal snow and permanent ice masses of this region over the past decades. The open access and increasing availability of remote sensing products has produced a substantial improvement in our understanding of the current state and recent changes of the Andean cryosphere, allowing an unprecedented detail in their identification and monitoring at local and regional scales. Analyses of snow cover maps has allowed the identification of seasonal patterns and long term trends in snow accumulation for most of the Andes, with some sectors in central Chile and central-western Argentina showing a clear decline in snowfall and snow persistence since 2010. This recent shortage of mountain snow has caused an extended, severe drought that is unprecedented in the hydrological and climatological records from this region. Together with data from global glacier inventories, detailed inventories at local/regional scales are now also freely available, providing important new information for glaciological, hydrological and climatological assessments in different sectors of the Andes. Numerous studies largely based on field measurements and/or remote sensing techniques have documented the recent glacier shrinkage throughout the Andes. This observed ice mass loss has put Andean glaciers among the highest contributors to sea level rise per unit area. Other recent studies have focused on rock glaciers, showing that in extensive semi-arid sectors of the Andes these mountain permafrost features contain large reserves of freshwater and may play a crucial role as future climate becomes warmer and drier in this region. Many relevant issues remain to be investigated, however, including an improved estimation of ice volumes at local scales, and detailed assessments of the hydrological significance of the different components of the cryosphere in Andean river basins. تحتوي جبال الأنديز كوردييرا على الغلاف الجليدي الأكثر تنوعًا على الأرض، بما في ذلك المناطق الشاسعة التي تغطيها الثلوج الموسمية، والعديد من الأنهار الجليدية الاستوائية وغير الاستوائية، والعديد من التضاريس الجبلية دائمة التجمد. نستعرض هنا بعض التطورات الحديثة في دراسة المكونات الرئيسية للغلاف الجليدي في جبال الأنديز، ونناقش التغيرات التي لوحظت في الثلوج الموسمية والكتل الجليدية الدائمة لهذه المنطقة على مدى العقود الماضية. أدى الوصول المفتوح وزيادة توافر منتجات الاستشعار عن بعد إلى تحسن كبير في فهمنا للحالة الراهنة والتغيرات الأخيرة في الغلاف الجليدي للأنديز، مما سمح بتفاصيل غير مسبوقة في تحديدها ورصدها على المستويين المحلي والإقليمي. سمحت تحليلات خرائط الغطاء الثلجي بتحديد الأنماط الموسمية والاتجاهات طويلة الأجل في تراكم الثلوج في معظم جبال الأنديز، حيث أظهرت بعض القطاعات في وسط تشيلي ووسط غرب الأرجنتين انخفاضًا واضحًا في تساقط الثلوج واستمرارها منذ عام 2010. وقد تسبب هذا النقص الأخير في الثلوج الجبلية في جفاف شديد ممتد لم يسبق له مثيل في السجلات الهيدرولوجية والمناخية من هذه المنطقة. إلى جانب البيانات المستمدة من قوائم الجرد العالمية للأنهار الجليدية، تتوفر الآن أيضًا قوائم جرد مفصلة على المستويات المحلية/الإقليمية مجانًا، مما يوفر معلومات جديدة مهمة للتقييمات الجليدية والهيدرولوجية والمناخية في قطاعات مختلفة من جبال الأنديز. وثقت العديد من الدراسات التي تستند إلى حد كبير إلى القياسات الميدانية و/أو تقنيات الاستشعار عن بعد الانكماش الأخير للأنهار الجليدية في جميع أنحاء جبال الأنديز. وقد وضع فقدان الكتلة الجليدية الملحوظ الأنهار الجليدية في الأنديز بين أعلى المساهمين في ارتفاع مستوى سطح البحر لكل وحدة مساحة. ركزت دراسات حديثة أخرى على الأنهار الجليدية الصخرية، وأظهرت أنه في القطاعات شبه القاحلة الواسعة في جبال الأنديز، تحتوي هذه المعالم الجبلية دائمة التجمد على احتياطيات كبيرة من المياه العذبة وقد تلعب دورًا حاسمًا حيث يصبح المناخ المستقبلي أكثر دفئًا وجفافًا في هذه المنطقة. ومع ذلك، لا يزال يتعين التحقيق في العديد من القضايا ذات الصلة، بما في ذلك تحسين تقدير أحجام الجليد على المستويات المحلية، وإجراء تقييمات مفصلة للأهمية الهيدرولوجية لمختلف مكونات الغلاف الجليدي في أحواض أنهار الأنديز.

Abstract. The mountain cryosphere of mainland Europe is recognized to have important impacts on a range of environmental processes. In this paper, we provide an overview on the current knowledge on snow, glacier, and permafrost processes, as well as their past, current, and future evolution. We additionally provide an assessment of current cryosphere research in Europe and point to the different domains requiring further research. Emphasis is given to our understanding of climate–cryosphere interactions, cryosphere controls on physical and biological mountain systems, and related impacts. By the end of the century, Europe's mountain cryosphere will have changed to an extent that will impact the landscape, the hydrological regimes, the water resources, and the infrastructure. The impacts will not remain confined to the mountain area but also affect the downstream lowlands, entailing a wide range of socioeconomical consequences. European mountains will have a completely different visual appearance, in which low- and mid-range-altitude glaciers will have disappeared and even large valley glaciers will have experienced significant retreat and mass loss. Due to increased air temperatures and related shifts from solid to liquid precipitation, seasonal snow lines will be found at much higher altitudes, and the snow season will be much shorter than today. These changes in snow and ice melt will cause a shift in the timing of discharge maxima, as well as a transition of runoff regimes from glacial to nival and from nival to pluvial. This will entail significant impacts on the seasonality of high-altitude water availability, with consequences for water storage and management in reservoirs for drinking water, irrigation, and hydropower production. Whereas an upward shift of the tree line and expansion of vegetation can be expected into current periglacial areas, the disappearance of permafrost at lower altitudes and its warming at higher elevations will likely result in mass movements and process chains beyond historical experience. Future cryospheric research has the responsibility not only to foster awareness of these expected changes and to develop targeted strategies to precisely quantify their magnitude and rate of occurrence but also to help in the development of approaches to adapt to these changes and to mitigate their consequences. Major joint efforts are required in the domain of cryospheric monitoring, which will require coordination in terms of data availability and quality. In particular, we recognize the quantification of high-altitude precipitation as a key source of uncertainty in projections of future changes. Improvements in numerical modeling and a better understanding of process chains affecting high-altitude mass movements are the two further fields that – in our view – future cryospheric research should focus on.

Most of the world’s mountain glaciers have been retreating for more than a century in response to climate change. Glacier retreat is evident on all continents, and the rate of retreat has accelerated during recent decades. Accurate, spatially explicit information on the position of glacier margins over time is useful for analyzing patterns of glacier retreat and measuring reductions in glacier surface area. This information is also essential for evaluating how mountain ecosystems are evolving due to climate warming and the attendant glacier retreat. Here, we present a non-comprehensive spatially explicit dataset showing multiple positions of glacier fronts since the Little Ice Age (LIA) maxima, including many data from the pre-satellite era. The dataset is based on multiple historical archival records including topographical maps; repeated photographs, paintings, and aerial or satellite images with a supplement of geochronology; and own field data. We provide ESRI shapefiles showing 728 past positions of 94 glacier fronts from all continents, except Antarctica, covering the period between the Little Ice Age maxima and the present. On average, the time series span the past 190 years. From 2 to 46 past positions per glacier are depicted (on average: 7.8).

AbstractThe worldwide retreat of glaciers is causing a faster than ever increase in ice‐free areas that are leading to the emergence of new ecosystems. Understanding the dynamics of these environments is critical to predicting the consequences of climate change on mountains and at high latitudes. Climatic differences between regions of the world could modulate the emergence of biodiversity and functionality after glacier retreat, yet global tests of this hypothesis are lacking. Nematodes are the most abundant soil animals, with keystone roles in ecosystem functioning, but the lack of global‐scale studies limits our understanding of how the taxonomic and functional diversity of nematodes changes during the colonization of proglacial landscapes. We used environmental DNA metabarcoding to characterize nematode communities of 48 glacier forelands from five continents. We assessed how different facets of biodiversity change with the age of deglaciated terrains and tested the hypothesis that colonization patterns are different across forelands with different climatic conditions. Nematodes colonized ice‐free areas almost immediately. Both taxonomic and functional richness quickly increased over time, but the increase in nematode diversity was modulated by climate, so that colonization started earlier in forelands with mild summer temperatures. Colder forelands initially hosted poor communities, but the colonization rate then accelerated, eventually leveling biodiversity differences between climatic regimes in the long term. Immediately after glacier retreat, communities were dominated by colonizer taxa with short generation time and r‐ecological strategy but community composition shifted through time, with increased frequency of more persister taxa with K‐ecological strategy. These changes mostly occurred through the addition of new traits instead of their replacement during succession. The effects of local climate on nematode colonization led to heterogeneous but predictable patterns around the world that likely affect soil communities and overall ecosystem development.

Worldwide, the rapid shrinking of glaciers in response to ongoing climate change is modifying the glacial meltwater contribution to hydrosystems in glacierized catchments. Determining the influence of glacial runoff to streams is therefore of critical importance to evaluate potential impact of glacier retreat on water quality and aquatic biota. This task has challenged both glacier hydrologists and ecologists over the last 20 yr due to both structural and functional complexity of the glacier–stream system interface. Here we propose quantifying the diurnal cycle amplitude of the streamflow to determine the glacial influence in glacierized catchments. We performed water-level measurements using water pressure loggers over 10 months at 30 min time steps in 15 stream sites in 2 glacier-fed catchments in the Ecuadorian Andes (> 4000 m a.s.l.) where no perennial snow cover is observed outside the glaciers. For each stream site, we performed wavelet analyses on water-level time series, determined the scale-averaged wavelet power spectrum at 24 h scale and defined three metrics, namely the power, frequency and temporal clustering of the diurnal flow variation. The three metrics were then compared to the percentage of the glacier cover in the catchments, a metric of glacial influence widely used in the literature. As expected, we found that the diurnal variation power of glacier-fed streams decreased downstream with the addition of non-glacial tributaries. We also found that the diurnal variation power and the percentage of the glacier cover in the catchment were significantly positively correlated. Furthermore, we found that our method permits the detection of glacial signal in supposedly non-glacial sites, thereby revealing glacial meltwater resurgence. While we specifically focused on the tropical Andes in this paper, our approach to determine glacial influence may have potential applications in temperate and arctic glacierized catchments. The measure of diurnal water amplitude therefore appears as a powerful and cost-effective tool to understand the hydrological links between glaciers and hydrosystems better and assess the consequences of rapid glacier shrinking.

Projected future glacier shrinkage, however, will lead to a long-term reduction in dry season river discharge from glacierized catchments. This glacier retreat is closely related to the observed increase in high-elevation, surface air temperature in the region. Future projections using a simple freezing level height- equilibrium-line altitude scaling approach suggest that glaciers in the inner tropics, such as Antizana in Ecuador, may be most vulnerable to future warming while glaciers in the more arid outer tropics, such as Zongo in Bolivia, may persist, albeit in a smaller size, throughout the 21st century regardless of emission scenario. Nonetheless many uncertainties persist, most notably problems with accurate snowfall measurements in the glacier accumulation zone, uncertainties in establishing accurate thickness measurements on glaciers, unknown future changes associated with local-scale circulation and cloud cover affecting glacier energy balance, the role of aerosols and in particular black carbon deposition on Andean glaciers, and the role of groundwater and aquifers interacting with glacier meltwater. The reduction in water supply for export-oriented agriculture, mining, hydropower production and human consumption are the most commonly discussed concerns associated with glacier retreat, but many other aspects including glacial hazards, tourism and recreation, and ecosystem integrity are also affected by glacier retreat. Social and political problems surrounding water allocation for subsistence farming have led to conflicts due to lack of adequate water governance. Local water management practices in many regions reflect cultural belief systems, perceptions and spiritual values and glacier retreat in some places is seen as a threat to these local livelihoods. Comprehensive adaptation strategies, if they are to be successful, therefore need to consider science, policy, culture and practice, and involve local populations. Planning needs to be based not only on future scenarios derived from physically-based numerical models, but must also consider societal needs, economic agendas, political conflicts, socioeconomic inequality and cultural values. This review elaborates on the need for adaptation as well as the challenges and constraints many adaptation projects are faced with, and lays out future directions where opportunities exist to develop successful, culturally acceptable and sustainable adaptation strategies.

The aim of this paper is to provide the community with a comprehensive overview of the studies of glaciers in the tropical Andes conducted in recent decades leading to the current status of the glaciers in the context of climate change. In terms of changes in surface area and length, we show that the glacier retreat in the tropical Andes over the last three decades is unprecedented since the maximum extension of the LIA (mid 17th–early 18th century). In terms of changes in mass balance, although there have been some sporadic gains on several glaciers, we show that the trend has been quite negative over the past 50 yr, with a mean mass balance deficit for glaciers in the tropical Andes that is slightly more negative than the computed global average. A break point in the trend appeared in the late 1970s with mean annual mass balance per year decreasing from −0.2 m w.e. in the period 1964–1975 to −0.76 m w.e. in the period 1976–2010. In addition, even if glaciers are currently retreating everywhere in the tropical Andes, it should be noted that as a percentage, this is much more pronounced on small glaciers at low altitudes that do not have a permanent accumulation zone, and which could disappear in the coming years/decades. Monthly mass balance measurements performed in Bolivia, Ecuador and Colombia showed that variability of the surface temperature of the Pacific Ocean is the main factor governing variability of the mass balance variability at the interannual to decadal time scale. Precipitation did not display a significant trend in the tropical Andes in the 20th century, and consequently cannot explain the glacier recession. On the other hand, temperature increased at a significant rate of 0.10 °C decade−1 in the last 70 yr. The higher frequency of El Niño events and changes in its spatial and temporal occurrence since the late 1970s together with a warming troposphere over the tropical Andes may thus explain much of the recent dramatic shrinkage of glaciers in this part of the world.

Glaciers in the dry Chilean Andes provide important ecological services, yet their mass balance response to past and ongoing climate change has been little studied. This study examines the recent (2002–2015), historical (1955–2005), and past (<1900) mass balance history of the high-altitude Guanaco Glacier (29.34°S, >5000 m), using a combination of glaciological, geodetic, and ice core observations. Mass balance has been predominantly negative since 2002. Analysis of mass balance and meteorological data since 2002 suggests that mass balance is currently mostly sensitive to precipitation variations, while low temperatures, aridity and high solar radiation and wind speeds cause large sublimation losses and limited melting. Mass balance reconstructed by geodetic methods shows that Guanaco Glacier has been losing mass since at least 1955, and that mass loss has increased over time until present. An ice core recovered from the deepest part of the glacier in 2008 revealed that the glacier is cold-based with a −5.5°C basal temperature and a warm reversal of the temperature profile above 60-m depth attributed to the recent atmospheric warming trend. Detailed stratigraphic and stable isotope analyses of the upper 20 m of the core revealed seasonal cycles in the δ18O and δ2H records with periods varying between 0.5 and 3 m. w.e. a–1. Deuterium excess values larger than 10‰ suggest limited post-depositional sublimation, while the presence of numerous refrozen ice layers indicate significant summer melt. Tritium concentration in the upper 20 m of the core was very low, while 210Pb was undetected, indicating that the glacier surface in 2008 was at least 100 years old. Taken together, these results suggest that Guanaco Glacier formed under drastically different climate conditions than today, with humid conditions causing high accumulation rates, reduced sublimation and increased melting. Reconstruction of mass balance based on correlations with precipitation and streamflow records show periods of sustained mass gain in the early 20th century and the 1980s, separated by periods of mass loss. The southern migration of the South Pacific Subtropical High over the course of the 20th and 21st centuries is proposed as the main mechanism explaining the progressive precipitation starvation of glaciers in this area.

Abstract Mechanisms underlying plant succession remain highly debated. A global quantification of the relative importance of species addition versus replacement is lacking due to the local scope of most studies. We quantified their role in the variation of plant communities colonizing the forelands of 46 retreating glaciers distributed worldwide, using both environmental DNA and traditional surveys. Both mechanisms concur in determining community changes over time but their relative importance varied over time along successions. Taxa addition predominated immediately after glacier retreat, as expected in harsh environments, while replacement became more important for late-successional communities. Those changes were aligned with total beta-diversity changes, which were larger between early successional communities than between late-successional communities (>50 years since glacier retreat). Despite the complexity of community assembly over plant succession, our global pattern suggests a generalized shift from the dominance of facilitation and/or stochastic processes in early successional communities to a predominance of competition later on.

La cordillère des Andes contient la cryosphère la plus diversifiée sur Terre, y compris de vastes zones couvertes de neige saisonnière, de nombreux glaciers tropicaux et extratropicaux et de nombreux reliefs de pergélisol montagneux. Ici, nous passons en revue quelques avancées récentes dans l'étude des principales composantes de la cryosphère dans les Andes, et discutons des changements observés dans la neige saisonnière et les masses de glace permanentes de cette région au cours des dernières décennies. Le libre accès et la disponibilité croissante des produits de télédétection ont considérablement amélioré notre compréhension de l'état actuel et des changements récents de la cryosphère andine, permettant un détail sans précédent dans leur identification et leur suivi à l'échelle locale et régionale. Les analyses des cartes de couverture neigeuse ont permis d'identifier les tendances saisonnières et les tendances à long terme de l'accumulation de neige pour la plupart des Andes, certains secteurs du centre du Chili et du centre-ouest de l'Argentine montrant une nette diminution des chutes de neige et de la persistance de la neige depuis 2010. Cette récente pénurie de neige de montagne a provoqué une sécheresse prolongée et sévère sans précédent dans les registres hydrologiques et climatologiques de cette région. En plus des données provenant des inventaires mondiaux des glaciers, des inventaires détaillés à l'échelle locale/régionale sont désormais également disponibles gratuitement, fournissant de nouvelles informations importantes pour les évaluations glaciologiques, hydrologiques et climatologiques dans différents secteurs des Andes. De nombreuses études largement basées sur des mesures sur le terrain et/ou des techniques de télédétection ont documenté le récent rétrécissement des glaciers dans les Andes. Cette perte de masse de glace observée a placé les glaciers andins parmi les plus grands contributeurs à l'élévation du niveau de la mer par unité de surface. D'autres études récentes se sont concentrées sur les glaciers rocheux, montrant que dans de vastes secteurs semi-arides des Andes, ces caractéristiques du pergélisol de montagne contiennent de grandes réserves d'eau douce et peuvent jouer un rôle crucial à mesure que le climat futur devient plus chaud et plus sec dans cette région. De nombreuses questions pertinentes restent cependant à étudier, notamment une meilleure estimation des volumes de glace à l'échelle locale et des évaluations détaillées de l'importance hydrologique des différentes composantes de la cryosphère dans les bassins fluviaux andins. La Cordillera de los Andes contiene la criosfera más diversa de la Tierra, incluidas extensas áreas cubiertas por nieve estacional, numerosos glaciares tropicales y extratropicales y muchos accidentes geográficos de permafrost de montaña. Aquí, revisamos algunos avances recientes en el estudio de los principales componentes de la criosfera en los Andes, y discutimos los cambios observados en la nieve estacional y las masas de hielo permanentes de esta región en las últimas décadas. El acceso abierto y la creciente disponibilidad de productos de teledetección ha producido una mejora sustancial en nuestra comprensión del estado actual y los cambios recientes de la criosfera andina, lo que permite un detalle sin precedentes en su identificación y monitoreo a escala local y regional. Los análisis de los mapas de la cubierta de nieve han permitido identificar patrones estacionales y tendencias a largo plazo en la acumulación de nieve para la mayor parte de los Andes, y algunos sectores en el centro de Chile y el centro-oeste de Argentina muestran una clara disminución de las nevadas y la persistencia de la nieve desde 2010. Esta reciente escasez de nieve de montaña ha provocado una prolongada y severa sequía que no tiene precedentes en los registros hidrológicos y climatológicos de esta región. Junto con los datos de los inventarios mundiales de glaciares, los inventarios detallados a escala local/regional ahora también están disponibles gratuitamente, proporcionando nueva información importante para las evaluaciones glaciológicas, hidrológicas y climatológicas en diferentes sectores de los Andes. Numerosos estudios basados en gran medida en mediciones de campo y/o técnicas de teledetección han documentado la reciente contracción de los glaciares en los Andes. Esta pérdida de masa de hielo observada ha colocado a los glaciares andinos entre los que más contribuyen al aumento del nivel del mar por unidad de área. Otros estudios recientes se han centrado en los glaciares de roca, lo que demuestra que en amplios sectores semiáridos de los Andes estas características de permafrost de montaña contienen grandes reservas de agua dulce y pueden desempeñar un papel crucial a medida que el clima futuro se vuelva más cálido y seco en esta región. Sin embargo, quedan por investigar muchas cuestiones relevantes, incluida una mejor estimación de los volúmenes de hielo a escala local y evaluaciones detalladas de la importancia hidrológica de los diferentes componentes de la criosfera en las cuencas fluviales andinas. The Andes Cordillera contains the most diverse cryosphere on Earth, including extensive areas covered by seasonal snow, numerous tropical and extratropical glaciers, and many mountain permafrost landforms. Here, we review some recent advances in the study of the main components of the cryosphere in the Andes, and discuss the changes observed in the seasonal snow and permanent ice masses of this region over the past decades. The open access and increasing availability of remote sensing products has produced a substantial improvement in our understanding of the current state and recent changes of the Andean cryosphere, allowing an unprecedented detail in their identification and monitoring at local and regional scales. Analyses of snow cover maps has allowed the identification of seasonal patterns and long term trends in snow accumulation for most of the Andes, with some sectors in central Chile and central-western Argentina showing a clear decline in snowfall and snow persistence since 2010. This recent shortage of mountain snow has caused an extended, severe drought that is unprecedented in the hydrological and climatological records from this region. Together with data from global glacier inventories, detailed inventories at local/regional scales are now also freely available, providing important new information for glaciological, hydrological and climatological assessments in different sectors of the Andes. Numerous studies largely based on field measurements and/or remote sensing techniques have documented the recent glacier shrinkage throughout the Andes. This observed ice mass loss has put Andean glaciers among the highest contributors to sea level rise per unit area. Other recent studies have focused on rock glaciers, showing that in extensive semi-arid sectors of the Andes these mountain permafrost features contain large reserves of freshwater and may play a crucial role as future climate becomes warmer and drier in this region. Many relevant issues remain to be investigated, however, including an improved estimation of ice volumes at local scales, and detailed assessments of the hydrological significance of the different components of the cryosphere in Andean river basins. تحتوي جبال الأنديز كوردييرا على الغلاف الجليدي الأكثر تنوعًا على الأرض، بما في ذلك المناطق الشاسعة التي تغطيها الثلوج الموسمية، والعديد من الأنهار الجليدية الاستوائية وغير الاستوائية، والعديد من التضاريس الجبلية دائمة التجمد. نستعرض هنا بعض التطورات الحديثة في دراسة المكونات الرئيسية للغلاف الجليدي في جبال الأنديز، ونناقش التغيرات التي لوحظت في الثلوج الموسمية والكتل الجليدية الدائمة لهذه المنطقة على مدى العقود الماضية. أدى الوصول المفتوح وزيادة توافر منتجات الاستشعار عن بعد إلى تحسن كبير في فهمنا للحالة الراهنة والتغيرات الأخيرة في الغلاف الجليدي للأنديز، مما سمح بتفاصيل غير مسبوقة في تحديدها ورصدها على المستويين المحلي والإقليمي. سمحت تحليلات خرائط الغطاء الثلجي بتحديد الأنماط الموسمية والاتجاهات طويلة الأجل في تراكم الثلوج في معظم جبال الأنديز، حيث أظهرت بعض القطاعات في وسط تشيلي ووسط غرب الأرجنتين انخفاضًا واضحًا في تساقط الثلوج واستمرارها منذ عام 2010. وقد تسبب هذا النقص الأخير في الثلوج الجبلية في جفاف شديد ممتد لم يسبق له مثيل في السجلات الهيدرولوجية والمناخية من هذه المنطقة. إلى جانب البيانات المستمدة من قوائم الجرد العالمية للأنهار الجليدية، تتوفر الآن أيضًا قوائم جرد مفصلة على المستويات المحلية/الإقليمية مجانًا، مما يوفر معلومات جديدة مهمة للتقييمات الجليدية والهيدرولوجية والمناخية في قطاعات مختلفة من جبال الأنديز. وثقت العديد من الدراسات التي تستند إلى حد كبير إلى القياسات الميدانية و/أو تقنيات الاستشعار عن بعد الانكماش الأخير للأنهار الجليدية في جميع أنحاء جبال الأنديز. وقد وضع فقدان الكتلة الجليدية الملحوظ الأنهار الجليدية في الأنديز بين أعلى المساهمين في ارتفاع مستوى سطح البحر لكل وحدة مساحة. ركزت دراسات حديثة أخرى على الأنهار الجليدية الصخرية، وأظهرت أنه في القطاعات شبه القاحلة الواسعة في جبال الأنديز، تحتوي هذه المعالم الجبلية دائمة التجمد على احتياطيات كبيرة من المياه العذبة وقد تلعب دورًا حاسمًا حيث يصبح المناخ المستقبلي أكثر دفئًا وجفافًا في هذه المنطقة. ومع ذلك، لا يزال يتعين التحقيق في العديد من القضايا ذات الصلة، بما في ذلك تحسين تقدير أحجام الجليد على المستويات المحلية، وإجراء تقييمات مفصلة للأهمية الهيدرولوجية لمختلف مكونات الغلاف الجليدي في أحواض أنهار الأنديز.

Abstract. The mountain cryosphere of mainland Europe is recognized to have important impacts on a range of environmental processes. In this paper, we provide an overview on the current knowledge on snow, glacier, and permafrost processes, as well as their past, current, and future evolution. We additionally provide an assessment of current cryosphere research in Europe and point to the different domains requiring further research. Emphasis is given to our understanding of climate–cryosphere interactions, cryosphere controls on physical and biological mountain systems, and related impacts. By the end of the century, Europe's mountain cryosphere will have changed to an extent that will impact the landscape, the hydrological regimes, the water resources, and the infrastructure. The impacts will not remain confined to the mountain area but also affect the downstream lowlands, entailing a wide range of socioeconomical consequences. European mountains will have a completely different visual appearance, in which low- and mid-range-altitude glaciers will have disappeared and even large valley glaciers will have experienced significant retreat and mass loss. Due to increased air temperatures and related shifts from solid to liquid precipitation, seasonal snow lines will be found at much higher altitudes, and the snow season will be much shorter than today. These changes in snow and ice melt will cause a shift in the timing of discharge maxima, as well as a transition of runoff regimes from glacial to nival and from nival to pluvial. This will entail significant impacts on the seasonality of high-altitude water availability, with consequences for water storage and management in reservoirs for drinking water, irrigation, and hydropower production. Whereas an upward shift of the tree line and expansion of vegetation can be expected into current periglacial areas, the disappearance of permafrost at lower altitudes and its warming at higher elevations will likely result in mass movements and process chains beyond historical experience. Future cryospheric research has the responsibility not only to foster awareness of these expected changes and to develop targeted strategies to precisely quantify their magnitude and rate of occurrence but also to help in the development of approaches to adapt to these changes and to mitigate their consequences. Major joint efforts are required in the domain of cryospheric monitoring, which will require coordination in terms of data availability and quality. In particular, we recognize the quantification of high-altitude precipitation as a key source of uncertainty in projections of future changes. Improvements in numerical modeling and a better understanding of process chains affecting high-altitude mass movements are the two further fields that – in our view – future cryospheric research should focus on.

Most of the world’s mountain glaciers have been retreating for more than a century in response to climate change. Glacier retreat is evident on all continents, and the rate of retreat has accelerated during recent decades. Accurate, spatially explicit information on the position of glacier margins over time is useful for analyzing patterns of glacier retreat and measuring reductions in glacier surface area. This information is also essential for evaluating how mountain ecosystems are evolving due to climate warming and the attendant glacier retreat. Here, we present a non-comprehensive spatially explicit dataset showing multiple positions of glacier fronts since the Little Ice Age (LIA) maxima, including many data from the pre-satellite era. The dataset is based on multiple historical archival records including topographical maps; repeated photographs, paintings, and aerial or satellite images with a supplement of geochronology; and own field data. We provide ESRI shapefiles showing 728 past positions of 94 glacier fronts from all continents, except Antarctica, covering the period between the Little Ice Age maxima and the present. On average, the time series span the past 190 years. From 2 to 46 past positions per glacier are depicted (on average: 7.8).

AbstractThe worldwide retreat of glaciers is causing a faster than ever increase in ice‐free areas that are leading to the emergence of new ecosystems. Understanding the dynamics of these environments is critical to predicting the consequences of climate change on mountains and at high latitudes. Climatic differences between regions of the world could modulate the emergence of biodiversity and functionality after glacier retreat, yet global tests of this hypothesis are lacking. Nematodes are the most abundant soil animals, with keystone roles in ecosystem functioning, but the lack of global‐scale studies limits our understanding of how the taxonomic and functional diversity of nematodes changes during the colonization of proglacial landscapes. We used environmental DNA metabarcoding to characterize nematode communities of 48 glacier forelands from five continents. We assessed how different facets of biodiversity change with the age of deglaciated terrains and tested the hypothesis that colonization patterns are different across forelands with different climatic conditions. Nematodes colonized ice‐free areas almost immediately. Both taxonomic and functional richness quickly increased over time, but the increase in nematode diversity was modulated by climate, so that colonization started earlier in forelands with mild summer temperatures. Colder forelands initially hosted poor communities, but the colonization rate then accelerated, eventually leveling biodiversity differences between climatic regimes in the long term. Immediately after glacier retreat, communities were dominated by colonizer taxa with short generation time and r‐ecological strategy but community composition shifted through time, with increased frequency of more persister taxa with K‐ecological strategy. These changes mostly occurred through the addition of new traits instead of their replacement during succession. The effects of local climate on nematode colonization led to heterogeneous but predictable patterns around the world that likely affect soil communities and overall ecosystem development.

Worldwide, the rapid shrinking of glaciers in response to ongoing climate change is modifying the glacial meltwater contribution to hydrosystems in glacierized catchments. Determining the influence of glacial runoff to streams is therefore of critical importance to evaluate potential impact of glacier retreat on water quality and aquatic biota. This task has challenged both glacier hydrologists and ecologists over the last 20 yr due to both structural and functional complexity of the glacier–stream system interface. Here we propose quantifying the diurnal cycle amplitude of the streamflow to determine the glacial influence in glacierized catchments. We performed water-level measurements using water pressure loggers over 10 months at 30 min time steps in 15 stream sites in 2 glacier-fed catchments in the Ecuadorian Andes (> 4000 m a.s.l.) where no perennial snow cover is observed outside the glaciers. For each stream site, we performed wavelet analyses on water-level time series, determined the scale-averaged wavelet power spectrum at 24 h scale and defined three metrics, namely the power, frequency and temporal clustering of the diurnal flow variation. The three metrics were then compared to the percentage of the glacier cover in the catchments, a metric of glacial influence widely used in the literature. As expected, we found that the diurnal variation power of glacier-fed streams decreased downstream with the addition of non-glacial tributaries. We also found that the diurnal variation power and the percentage of the glacier cover in the catchment were significantly positively correlated. Furthermore, we found that our method permits the detection of glacial signal in supposedly non-glacial sites, thereby revealing glacial meltwater resurgence. While we specifically focused on the tropical Andes in this paper, our approach to determine glacial influence may have potential applications in temperate and arctic glacierized catchments. The measure of diurnal water amplitude therefore appears as a powerful and cost-effective tool to understand the hydrological links between glaciers and hydrosystems better and assess the consequences of rapid glacier shrinking.

Projected future glacier shrinkage, however, will lead to a long-term reduction in dry season river discharge from glacierized catchments. This glacier retreat is closely related to the observed increase in high-elevation, surface air temperature in the region. Future projections using a simple freezing level height- equilibrium-line altitude scaling approach suggest that glaciers in the inner tropics, such as Antizana in Ecuador, may be most vulnerable to future warming while glaciers in the more arid outer tropics, such as Zongo in Bolivia, may persist, albeit in a smaller size, throughout the 21st century regardless of emission scenario. Nonetheless many uncertainties persist, most notably problems with accurate snowfall measurements in the glacier accumulation zone, uncertainties in establishing accurate thickness measurements on glaciers, unknown future changes associated with local-scale circulation and cloud cover affecting glacier energy balance, the role of aerosols and in particular black carbon deposition on Andean glaciers, and the role of groundwater and aquifers interacting with glacier meltwater. The reduction in water supply for export-oriented agriculture, mining, hydropower production and human consumption are the most commonly discussed concerns associated with glacier retreat, but many other aspects including glacial hazards, tourism and recreation, and ecosystem integrity are also affected by glacier retreat. Social and political problems surrounding water allocation for subsistence farming have led to conflicts due to lack of adequate water governance. Local water management practices in many regions reflect cultural belief systems, perceptions and spiritual values and glacier retreat in some places is seen as a threat to these local livelihoods. Comprehensive adaptation strategies, if they are to be successful, therefore need to consider science, policy, culture and practice, and involve local populations. Planning needs to be based not only on future scenarios derived from physically-based numerical models, but must also consider societal needs, economic agendas, political conflicts, socioeconomic inequality and cultural values. This review elaborates on the need for adaptation as well as the challenges and constraints many adaptation projects are faced with, and lays out future directions where opportunities exist to develop successful, culturally acceptable and sustainable adaptation strategies.

The aim of this paper is to provide the community with a comprehensive overview of the studies of glaciers in the tropical Andes conducted in recent decades leading to the current status of the glaciers in the context of climate change. In terms of changes in surface area and length, we show that the glacier retreat in the tropical Andes over the last three decades is unprecedented since the maximum extension of the LIA (mid 17th–early 18th century). In terms of changes in mass balance, although there have been some sporadic gains on several glaciers, we show that the trend has been quite negative over the past 50 yr, with a mean mass balance deficit for glaciers in the tropical Andes that is slightly more negative than the computed global average. A break point in the trend appeared in the late 1970s with mean annual mass balance per year decreasing from −0.2 m w.e. in the period 1964–1975 to −0.76 m w.e. in the period 1976–2010. In addition, even if glaciers are currently retreating everywhere in the tropical Andes, it should be noted that as a percentage, this is much more pronounced on small glaciers at low altitudes that do not have a permanent accumulation zone, and which could disappear in the coming years/decades. Monthly mass balance measurements performed in Bolivia, Ecuador and Colombia showed that variability of the surface temperature of the Pacific Ocean is the main factor governing variability of the mass balance variability at the interannual to decadal time scale. Precipitation did not display a significant trend in the tropical Andes in the 20th century, and consequently cannot explain the glacier recession. On the other hand, temperature increased at a significant rate of 0.10 °C decade−1 in the last 70 yr. The higher frequency of El Niño events and changes in its spatial and temporal occurrence since the late 1970s together with a warming troposphere over the tropical Andes may thus explain much of the recent dramatic shrinkage of glaciers in this part of the world.

Glaciers in the dry Chilean Andes provide important ecological services, yet their mass balance response to past and ongoing climate change has been little studied. This study examines the recent (2002–2015), historical (1955–2005), and past (<1900) mass balance history of the high-altitude Guanaco Glacier (29.34°S, >5000 m), using a combination of glaciological, geodetic, and ice core observations. Mass balance has been predominantly negative since 2002. Analysis of mass balance and meteorological data since 2002 suggests that mass balance is currently mostly sensitive to precipitation variations, while low temperatures, aridity and high solar radiation and wind speeds cause large sublimation losses and limited melting. Mass balance reconstructed by geodetic methods shows that Guanaco Glacier has been losing mass since at least 1955, and that mass loss has increased over time until present. An ice core recovered from the deepest part of the glacier in 2008 revealed that the glacier is cold-based with a −5.5°C basal temperature and a warm reversal of the temperature profile above 60-m depth attributed to the recent atmospheric warming trend. Detailed stratigraphic and stable isotope analyses of the upper 20 m of the core revealed seasonal cycles in the δ18O and δ2H records with periods varying between 0.5 and 3 m. w.e. a–1. Deuterium excess values larger than 10‰ suggest limited post-depositional sublimation, while the presence of numerous refrozen ice layers indicate significant summer melt. Tritium concentration in the upper 20 m of the core was very low, while 210Pb was undetected, indicating that the glacier surface in 2008 was at least 100 years old. Taken together, these results suggest that Guanaco Glacier formed under drastically different climate conditions than today, with humid conditions causing high accumulation rates, reduced sublimation and increased melting. Reconstruction of mass balance based on correlations with precipitation and streamflow records show periods of sustained mass gain in the early 20th century and the 1980s, separated by periods of mass loss. The southern migration of the South Pacific Subtropical High over the course of the 20th and 21st centuries is proposed as the main mechanism explaining the progressive precipitation starvation of glaciers in this area.
