Book Synopsis Glacier Evolution in a Changing World by : Danilo Godone
Download or read book Glacier Evolution in a Changing World written by Danilo Godone and published by BoD – Books on Demand. This book was released on 2017-10-04 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glaciers have always played an important role in human history, and currently, they are carefully observed as climate change sentinels. Glacier melt rate is increasing, and its mass balance is continuously negative. This issue deserves accurate and in-depth studies in order to, adequately, monitor its state. This circumstance in fact endangers the water supply, affecting human settlements but also creating new environments allowing the colonization by pioneer communities and the formation of new landscapes. This book is subdivided into two main sections in order to deal with the two topics of worldwide research on glaciers and ecology in glacial environments. In the first one "Glaciers in the World," several reviews and studies are collected. It is an overview of glaciers, their state, and research carried out in different continents and contexts. The second section "Glacial Ecosystems" focuses, on the other hand, on glacier environments and ecological researches.
Book Synopsis Recent Climate Change Impacts on Mountain Glaciers by : Mauri Pelto
Download or read book Recent Climate Change Impacts on Mountain Glaciers written by Mauri Pelto and published by John Wiley & Sons. This book was released on 2017-01-17 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glaciers are considered a key and an iconic indicator of climate change. The World Glacier Monitoring Service has noted that global alpine balance has been negative for 35 consecutive years. This highlights the dire future that alpine glaciers face. The goal of this volume is to tell the story, glacier by glacier, of response to climate change from 1984-2015. Of the 165 glaciers examined in 10 different alpine regions, 162 have retreated significantly. It is evident that the changes are significant, not happening at a "glacial" pace, and are profoundly affecting alpine regions. There is a consistent result that reverberates from mountain range to mountain range, which emphasizes that although regional glacier and climate feedbacks differ, global changes are driving the response. This book considers ten different glaciated regions around the individual glaciers, and offers a different tune to the same chorus of glacier volume loss in the face of climate change.

Book Synopsis The Little Ice Age by : Jean M. Grove
Download or read book The Little Ice Age written by Jean M. Grove and published by Routledge. This book was released on 2019-04-30 with total page 869 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evidence for the Little Ice Age, the most important fluctuation in global climate in historical times, is most dramatically represented by the advance of mountain glaciers in the sixteenth and seventeenth centuries and their retreat since about 1850. The effects on the landscape and the daily life of people have been particularly apparent in Norway and the Alps. This major book places an extensive body of material relating to Europe, in the form of documentary evidence of the history of the glaciers, their portrayal in paintings and maps, and measurements made by scientists and others, within a global perspective. It shows that the glacial history of mountain regions all over the world displays a similar pattern of climatic events. Furthermore, fluctuations on a comparable scale have occurred at intervals of a millennium or two throughout the last ten thousand years since the ice caps of North America and northwest Europe melted away. This is the first scholarly work devoted to the Little Ice Age, by an author whose research experience of the subject has been extensive. This book includes large numbers of maps, diagrams and photographs, many not published elsewhere, and very full bibliographies. It is a definitive work on the subject, and an excellent focus for the work of economic and social historians as well as glaciologists, climatologists, geographers, and specialists in mountain environment.
Book Synopsis The Great Ice Age by : R. C. L. Wilson
Download or read book The Great Ice Age written by R. C. L. Wilson and published by Psychology Press. This book was released on 2000 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Great Ice Age documents and explains the natural climatic and palaeoecologic changes that have occurred during the past 2.6 million years, outlining the emergence and global impact of our species during this period. Exploring a wide range of records of climate change, the authors demonstrate the interconnectivity of the components of the Earths climate system, show how the evidence for such change is obtained, and explain some of the problems in collecting and dating proxy climate data. One of the most dramatic aspects of humanity's rise is that it coincided with the beginnings of major environmental changes and a mass extinction that has the pace, and maybe magnitude, of those in the far-off past that stemmed from climate, geological and occasionally extraterrestrial events. This book reveals that anthropogenic effects on the world are not merely modern matters but date back perhaps a million years or more.

Book Synopsis Reconstructing Glacier Evolution Using a Flowline Model by : Julia Eis
Download or read book Reconstructing Glacier Evolution Using a Flowline Model written by Julia Eis and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Glacier mass change is one of the main causes of past sea-level rise and glaciers will continue to be a major contributor in the 21st century. Despite their importance, knowledge about past glacier mass changes is strongly limited. Whereas detailed observations exist for a very small number of glaciers, empirical evidence on a regional or global scale is largely incomplete, both spatially and temporally. The reconstruction of past glacier states by automatic numerical methods could fill this lack of information. Such reconstructions play a major role to fully understand the sea-level budget. They are crucial in terms of model validation, can be used to detect and improve model uncertainties, and they increase the confidence in projections. A framework, which provides all requirements to obtain these reconstructions is the Open Global Glacier Model (OGGM). It is an open source numerical glacier model, that is globally applicable by modeling each glacier individually, and developed for the simulation of glacier changes. However, providing realistic glacier changes with OGGM during the course of the entire 20th century requires an adequate initial state for every of the ∼200.000 glaciers worldwide. To find these initial states, this thesis presents an approach using the only given information for every individual glacier: past climate information and present-day geometry. Synthetic experiments showed that even under perfectly known but incomplete boundary conditions, this is an ill-posed inverse problem, leading to non-unique solutions. The synthetic environment enables the determination of the accuracy of the method, but on the other hand comparisons with real world observations are not possible. In order to facilitate such comparisons, a glacier-specific calibration of the mass balance model is introduced. This procedure finally allows for a validation.

Book Synopsis Past and Future Evolution of French Alpine Glaciers in a Changing Climate by : Jordi Bolibar Navarro
Download or read book Past and Future Evolution of French Alpine Glaciers in a Changing Climate written by Jordi Bolibar Navarro and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The European Alps are among the most affected regions in the world by climate change, displaying some of the strongest glacier retreat rates. Long-term interactions between society, mountain ecosystems and glaciers in the region raise important questions on the future evolution of glaciers and their derived environmental and socioeconomical impacts. In order to correctly assess the regional response of glaciers in the French Alps to climate change, there is a need for adequate modelling tools. In this work, we explore new ways to tackle both glacier evolution and glacio-hydrological modelling at a regional scale. Glacier evolution modelling has traditionally been performed using empirical or physical approaches, which are becoming increasingly challenging to optimize with the ever growing amount of available data. Here, we present, to our knowledge, the first effort ever to apply deep learning (i.e. deep artificial neural networks) to simulate the evolution of glaciers. Since both the climate and glacier systems are highly nonlinear, traditional linear mass balance models offer a limited representation of climate-glacier interactions. We show how important nonlinearities in glacier mass balance are captured by deep learning, substantially improving model performance over linear methods.This novel method was first applied in a study to reconstruct annual mass balance changes for all glaciers in the French Alps for the 1967-2015 period. Using climate reanalyses, topographical data and glacier inventories, we demonstrate how such an approach can be successfully used to reconstruct large-scale mass balance changes from observations. This study also offered new insights on how glaciers evolved in the French Alps during the last half century, confirming the rather neutral observed mass balance rates in the 1980s and displaying a well-marked acceleration in mass loss from the 2000s onwards. Important differences between regions are found, with the Mont-Blanc massif presenting the lowest mass loss and the Chablais being the most affected one. Secondly, we applied this modelling framework to simulate the future evolution of all glaciers in the region under multiple (N=29) climate change scenarios. Our estimates indicate that most ice volume in the region will be lost by the end of the 21st century independently from future climate scenarios. We predict average glacier volume losses of 74%, 80% and 88% under RCP 2.6 (n=3), RCP 4.5 (n=13) and RCP 8.5 (n=13), respectively. By the end of the 21st century the French Alps will be largely ice-free, with glaciers only remaining in the Mont-Blanc and Pelvoux massifs.
Book Synopsis Climate Driven Retreat of Mount Baker Glaciers and Changing Water Resources by : Mauri Pelto
Download or read book Climate Driven Retreat of Mount Baker Glaciers and Changing Water Resources written by Mauri Pelto and published by Springer. This book was released on 2015-11-02 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the impact of climate change on Mount Baker glaciers, USA, and the rivers surrounding them. Glaciers are natural reservoirs that yield their resource primarily on warm dry summer days when other sources are at their lowest yield. This natural tempering of drought conditions will be reduced as they retreat. Mount Baker, a volcano in the Cascades of Washington, is currently host to 12 principal glaciers with an area of 36.8 km2. The glaciers yield 125 million cubic meters of water each summer that is a resource for salmon, irrigation and hydropower to the Nooksack River and Baker River watersheds. Recent rapid retreat of all 22 glaciers is altering the runoff from the glaciers, impacting both the discharge and temperature of the Nooksack and Baker River. Over the last 30 years we have spent 270 nights camped on the mountain conducting 10,500 observations of snow depth and melt rate on Mount Baker. This data combined with observations of terminus change, area change and glacier runoff over the same 30 years allow an unusually comprehensive story to be told of the effects of climate change to Mount Baker Glaciers and the rivers that drain them.

Book Synopsis Plant Competition in a Changing World by : Judy Simon
Download or read book Plant Competition in a Changing World written by Judy Simon and published by Frontiers Media SA. This book was released on 2017-06-22 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Competitiveness describes a key ability important for plants to grow and survive abiotic and biotic stresses. Under optimal, but particularly under non-optimal conditions, plants compete for resources including nutrients, light, water, space, pollinators and other. Competition occurs above- and belowground. In resource-poor habitats, competition is generally considered to be more pronounced than in resource-rich habitats. Although competition occurs between different players within an ecosystem such as between plants and soil microorganisms, our topic focusses on plant-plant interactions and includes inter-specific competition between different species of similar and different life forms and intra-specific competition. Strategies for securing resources via spatial or temporal separation and different resource needs generally reduce competition. Increasingly important is the effect of invasive plants and subsequent decline in biodiversity and ecosystem function. Current knowledge and future climate predictions suggest that in some situations competition will be intensified with occurrence of increased abiotic (e.g. water and nutrient limitations) and biotic stresses (e.g. mass outbreak of insects), but competition might also decrease in situations where plant productivity and survival declines (e.g. habitats with degraded soils). Changing interactions, climate change and biological invasions place new challenges on ecosystems. Understanding processes and mechanisms that underlie the interactions between plants and environmental factors will aid predictions and intervention. There is much need to develop strategies to secure ecosystem services via primary productivity and to prevent the continued loss of biodiversity. This Research Topic provides an up-to-date account of knowledge on plant-plant interactions with a focus on identifying the mechanisms underpinning competitive ability. The Research Topic aims to showcase knowledge that links ecological relevance with physiological processes to better understanding plant and ecosystem function.
