Though not traditionally thought of as strategic natural resources, glaciers are a crucial part of our global ecosystem playing a fundamental role in the sustaining of life around the world. Comprising three quarters of the world's freshwater, they freeze in the winter and melt in the summer, supplying a steady flow of water for agriculture, livestock, industry and human consumption. The white of glacier surfaces reflect sunrays which otherwise warm our planet. Without them, many of the planet's rivers would run dry shortly after the winter snow-melt. A single mid-sized glacier in high mountain environments of places like California, Argentina, India, Kyrgyzstan, or Chile can provide an entire community with a sustained flow of drinking water for generations. On the other hand, when global temperatures rise, not only does glacier ice wither away into the oceans and cease to act as water reservoirs, but these massive ice bodies can become highly unstable and collapse into downstream environments, resulting in severe natural events like glacier tsunamis and other deadly environmental catastrophes. But despite their critical role in environmental sustainability, glaciers often exist well outside our environmental consciousness, and they are mostly unprotected from atmospheric impacts of global warming or from soot deriving from transportation emissions, or from certain types of industrial activity such as mining, which has been shown to have devastating consequences for glacier survival. Glaciers: The Politics of Ice is a scientific, cultural, and political examination of the cryosphere -- the earth's ice -- and the environmental policies that are slowly emerging to protect it. Jorge Daniel Taillant discusses the debates and negotiations behind the passage of the world's first glacier-protection law in the mid-2000s, and reveals the tension that quickly arose between industry, politicians, and environmentalists when an international mining company proposed dynamiting three glaciers to get at gold deposits underneath. The book is a quest to educate general society about the basic science behind glaciers, outlines current and future risks to their preservation, and reveals the intriguing politics behind glacier melting debates over policies and laws to protect the resource. Taillant also makes suggestions on what can be done to preserve these crucial sources of fresh water, from both a scientific and policymaking standpoint. Glaciers is a new window into one of the earth's most crucial and yet most ignored natural resources, and a call to reawaken our interest in the world's changing climate.

A never-before-seen look into the forbidding environment of glaciers, this book celebrates a realm of magnificent endangered beauty. Since 2005, renowned nature photographer James Balog has devoted himself to capturing glaciers and documenting their daily changes. These stunning images are a celebration of some of the most extraordinary natural formations on earth, as well as a dramatic and timely demonstration of the stark consequences resulting from global warming—from Alaska to Iceland to the Alps. As glaciologists for the Extreme Ice Survey, Balog and his team are conducting the most extensive glacier study ever, covering France, Switzerland, Iceland, Greenland, the United States (Alaska and Montana), Nepal, Bolivia, and Antarctica. Their high-resolution cameras capture approximately 4,000 images per year. From this collection of nearly half a million photos, Balog presents the most stunning panoramic photography of glaciers ever published.

The awesome beauty and majesty of glaciers, the world of ice which has shaped and reshaped large parts of the earth's surfaces, are presented here through more than one hundred photographs and a closely integrated, informed text. Austin Post's series of aerial photographs of glaciers along the North Pacific Coast of North America and into the interior ranges of Alaska, is supplemented with ground-based photographs taken in the course of glacier research and by additional illustrations from the Himalayas, Switzerland, Chile, and other parts of the world. The authors clearly explain the features illustrated. Their discussion of the effects of glaciers on the landscape, formation and mass balance, flow and fluctuations, moraines, ogives, and surface details is valuable for the general reader as well as the expert.

A passionate eyewitness account of the mysteries and looming demise of glaciers—and what their fate means for our shared future The ice sheets and glaciers that cover one-tenth of Earth's land surface are in grave peril. High in the Alps, Andes, and Himalaya, once-indomitable glaciers are retreating, even dying. Meanwhile, in Antarctica, thinning glaciers may be unlocking vast quantities of methane stored for millions of years beneath the ice. In Ice Rivers, renowned glaciologist Jemma Wadham offers a searing personal account of glaciers and the rapidly unfolding crisis that they—and we—face. Taking readers on a personal journey from Europe and Asia to Antarctica and South America, Wadham introduces majestic glaciers around the globe as individuals—even friends—each with their own unique character and place in their community. She challenges their first appearance as silent, passive, and lifeless, and reveals that glaciers are, in fact, as alive as a forest or soil, teeming with microbial life and deeply connected to almost everything we know. They influence crucial systems on which people depend, from lucrative fisheries to fertile croplands, and represent some of the most sensitive and dynamic parts of our world. Their fate is inescapably entwined with our own, and unless we act to abate the greenhouse warming of our planet the potential consequences are almost unfathomable. A riveting blend of cutting-edge research and tales of encounters with polar bears and survival under the midnight sun, Ice Rivers is an unforgettable portrait of—and love letter to—our vanishing icy wildernesses.

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.

Dynamics of Ice Sheets and Glaciers presents an introduction to the dynamics and thermodynamics of flowing ice masses on Earth. Based on an outline of general continuum mechanics, the different initial-boundary-value problems for the flow of ice sheets, ice shelves, ice caps and glaciers are systematically derived. Special emphasis is put on developing hierarchies of approximations for the different systems, and suitable numerical solution techniques are discussed. A separate chapter is devoted to glacial isostasy. The book is appropriate for graduate courses in glaciology, cryospheric sciences, environmental sciences, geophysics and related fields. Standard undergraduate knowledge of mathematics (calculus, linear algebra) and physics (classical mechanics, thermodynamics) provide a sufficient background for successfully studying the text.

The author of "Bodies from the Ash" and "Bodies from the Bog" takes readers on a captivating and creepy journey to learn about glaciers, hulking masses of moving ice that are now offering up many secrets of the past. Full color.
