Global Change and the Earth System


Book Description

Global Change and the Earth System describes what is known about the Earth system and the impact of changes caused by humans. It considers the consequences of these changes with respect to the stability of the Earth system and the well-being of humankind; as well as exploring future paths towards Earth-system science in support of global sustainability. The results presented here are based on 10 years of research on global change by many of the world's most eminent scholars. This valuable volume achieves a new level of integration and interdisciplinarity in treating global change.







The Secret Lives of Glaciers


Book Description

Our planet has over 400,000 glaciers and ice caps scattered across its surface, some 5.8 million square miles of ice. Fascinatingly, where there are glaciers, there are people, and the two have been interacting for the entirety of human history. But we know so little about that interaction, those human stories of glaciers. The Secret Lives of Glaciers explores glacier diversity in Iceland, highlighting the rich social and cultural context and variability amongst glaciers and people. Investigating glaciers and people together teaches us about how human society experiences being in the world today amidst increasing climatic changes and anthropogenic transformation of all of Earth's systems.




Glaciers and Ice Sheets in the Climate System


Book Description

Our realisation of how profoundly glaciers and ice sheets respond to climate change and impact sea level and the environment has propelled their study to the forefront of Earth system science. Aspects of this multidisciplinary endeavour now constitute major areas of research. This book is named after the international summer school held annually in the beautiful alpine village of Karthaus, Northern Italy, and consists of twenty chapters based on lectures from the school. They cover theory, methods, and observations, and introduce readers to essential glaciological topics such as ice-flow dynamics, polar meteorology, mass balance, ice-core analysis, paleoclimatology, remote sensing and geophysical methods, glacial isostatic adjustment, modern and past glacial fluctuations, and ice sheet reconstruction. The chapters were written by thirty-four contributing authors who are leading international authorities in their fields. The book can be used as a graduate-level textbook for a university course, and as a valuable reference guide for practising glaciologists and climate scientists.




Monitoring Climate Change Impacts


Book Description

The stresses associated with climate change are expected to be felt keenly as human population grows to a projected 9 billion by the middle of this century, increasing the demand for resources and supporting infrastructure. Therefore, information to assess vulnerabilities to climate change is needed to support policies and investments designed to increase resilience in human and Earth systems. There are currently many observing systems that capture elements of how climate is changing, for example, direct measurements of atmospheric and ocean temperature. Although those measurements are essential for understanding the scale and nature of climate change, they do not necessarily provide information about the impacts of climate change on humans that are especially relevant for political and economic planning and decision making. Monitoring Climate Change Impacts tackles the challenge of developing an illustrative suite of indicators, measurements (and the locations around the globe where the measurements can be applied), and metrics that are important for understanding global climate change and providing insight into environmental sustainability. Eight panels provided input on: cryosphere, land-surface and terrestrial ecosystems, hydrology and water resources, atmosphere, human health and other dimensions, oceans (both physical and biological/chemical), and natural disasters. The book also provides an illustrative set of metrics that are likely to be affected by climate change over the next 20-25 years and, when taken together, can potentially give advance warning of climate-related changes to the human and environment systems.




Climate Change


Book Description

Climate Change: Evidence and Causes is a jointly produced publication of The US National Academy of Sciences and The Royal Society. Written by a UK-US team of leading climate scientists and reviewed by climate scientists and others, the publication is intended as a brief, readable reference document for decision makers, policy makers, educators, and other individuals seeking authoritative information on the some of the questions that continue to be asked. Climate Change makes clear what is well-established and where understanding is still developing. It echoes and builds upon the long history of climate-related work from both national academies, as well as on the newest climate-change assessment from the United Nations' Intergovernmental Panel on Climate Change. It touches on current areas of active debate and ongoing research, such as the link between ocean heat content and the rate of warming.




Encyclopedia of Snow, Ice and Glaciers


Book Description

The earth’s cryosphere, which includes snow, glaciers, ice caps, ice sheets, ice shelves, sea ice, river and lake ice, and permafrost, contains about 75% of the earth’s fresh water. It exists at almost all latitudes, from the tropics to the poles, and plays a vital role in controlling the global climate system. It also provides direct visible evidence of the effect of climate change, and, therefore, requires proper understanding of its complex dynamics. This encyclopedia mainly focuses on the various aspects of snow, ice and glaciers, but also covers other cryospheric branches, and provides up-to-date information and basic concepts on relevant topics. It includes alphabetically arranged and professionally written, comprehensive and authoritative academic articles by well-known international experts in individual fields. The encyclopedia contains a broad spectrum of topics, ranging from the atmospheric processes responsible for snow formation; transformation of snow to ice and changes in their properties; classification of ice and glaciers and their worldwide distribution; glaciation and ice ages; glacier dynamics; glacier surface and subsurface characteristics; geomorphic processes and landscape formation; hydrology and sedimentary systems; permafrost degradation; hazards caused by cryospheric changes; and trends of glacier retreat on the global scale along with the impact of climate change. This book can serve as a source of reference at the undergraduate and graduate level and help to better understand snow, ice and glaciers. It will also be an indispensable tool containing specialized literature for geologists, geographers, climatologists, hydrologists, and water resources engineers; as well as for those who are engaged in the practice of agricultural and civil engineering, earth sciences, environmental sciences and engineering, ecosystem management, and other relevant subjects.




Thriving on Our Changing Planet


Book Description

We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities â€" social, economic, security, and more â€" that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet presents prioritized science, applications, and observations, along with related strategic and programmatic guidance, to support the U.S. civil space Earth observation program over the coming decade.




Meltdown


Book Description

We hear about pieces of ice the size of continents breaking off of Antarctica, rapidly melting glaciers in the Himalayas, and ice sheets in the Arctic crumbling to the sea, but does it really matter? Will melting glaciers change our lives? Absolutely.The ice ages and the interglacial periods like we live in now are built and destroyed by glaciers. Glaciers hold three quarters of our freshwater, yet we don't have laws to protection them from climate change. Melting glaciers raise the seas, alter global ecosystems, warm our climate and bring onfloods that swamp millions of acres of land destroying coastal ecosystems and leaving hundreds of millions homeless. Healthy glaciers help keep our planet cool by reflecting solar heat away from the Earth and provide critical freshwater supply to billions that live within their meltwater runoffbasins. But melting glaciers alter ocean temperature, warm the atmosphere and cause havoc to the ocean currents and to the global jet stream, causing inclement weather, prolonged and recurrent droughts, heavy rains and intense, frequent and unpredictable storms. As glaciers melt away, their criticalenvironmental functions and services will wither. And as climate change warms their core, their weakening internal structure will cause a growing number of glacier tsunamis that can send deadly massive ice blocks, rocks, earth and billions of liters of water rushing down mountain valleys that takeout anything in their path. It has happened before in the Himalayas, in the Central Andes, in the Rockies and Western Cascades, and in the European Alps and it will happen again. As glaciers melt so do the vast swaths of permafrost environments that thrive in their surroundings, where thawingmillenary terrain rich in ice but also in methane gas captured hundreds of thousands of years ago, is now released into the atmosphere intensifying climate change even further.In his new book Meltdown, Jorge Daniel Taillant takes readers deeper into the cryosphere and connects the dots between climate change, glacier melt and the impacts that receding glacier ice brings to livability on Earth, to our environments and to our neighborhoods. He walks us through thelittle-known realm of the periglacial environment, a world where invisible subsurface rock glaciers with solid ice cores that will outlive exposed glaciers in our warming climate, but will they suffice to maintain our cryosphere and climate ecology in balance? In two closing chapters Taillant looksat actions that can help stop climate change and save glaciers and also contrasts how society, politics and our leaders have responded to address the COVID-19 pandemic and yet largely failed to address the even larger looming and escalating crisis of climate change.Meltdown is about glaciers and their unfolding demise during one of the most critical moments of our climate crisis. We may still be in time to save the cryosphere, if we can reconsider glaciers in a whole new light and understand the critical role they play in our own sustainability and if we canawaken to see how through glacier melt, geological ages are changing right before our eyes.
