There is little dispute within the scientific community that humans are changing Earth's climate on a decadal to century time-scale. By the end of this century, without a reduction in emissions, atmospheric CO2 is projected to increase to levels that Earth has not experienced for more than 30 million years. As greenhouse gas emissions propel Earth toward a warmer climate state, an improved understanding of climate dynamics in warm environments is needed to inform public policy decisions. In Understanding Earth's Deep Past, the National Research Council reports that rocks and sediments that are millions of years old hold clues to how the Earth's future climate would respond in an environment with high levels of atmospheric greenhouse gases. Understanding Earth's Deep Past provides an assessment of both the demonstrated and underdeveloped potential of the deep-time geologic record to inform us about the dynamics of the global climate system. The report describes past climate changes, and discusses potential impacts of high levels of atmospheric greenhouse gases on regional climates, water resources, marine and terrestrial ecosystems, and the cycling of life-sustaining elements. While revealing gaps in scientific knowledge of past climate states, the report highlights a range of high priority research issues with potential for major advances in the scientific understanding of climate processes. This proposed integrated, deep-time climate research program would study how climate responded over Earth's different climate states, examine how climate responds to increased atmospheric carbon dioxide and other greenhouse gases, and clarify the processes that lead to anomalously warm polar and tropical regions and the impact on marine and terrestrial life. In addition to outlining a research agenda, Understanding Earth's Deep Past proposes an implementation strategy that will be an invaluable resource to decision-makers in the field, as well as the research community, advocacy organizations, government agencies, and college professors and students.

Paleontology is one of the most visible yet most misunderstood fields of science. Children dream of becoming paleontologists when they grow up. Museum visitors flock to exhibits on dinosaurs and other prehistoric animals. The media reports on fossil discoveries and new clues to mass extinctions. Nonetheless, misconceptions abound: paleontologists are assumed only to be interested in dinosaurs, and they are all too often imagined as bearded white men in battered cowboy hats. Roy Plotnick provides a behind-the-scenes look at paleontology as it exists today in all its complexity. He explores the field’s aims, methods, and possibilities, with an emphasis on the compelling personal stories of the scientists who have made it a career. Paleontologists study the entire history of life on Earth; they do not only use hammers and chisels to unearth fossils but are just as likely to work with cutting-edge computing technology. Plotnick presents the big questions about life’s history that drive paleontological research and shows why knowledge of Earth’s past is essential to understanding present-day environmental crises. He introduces readers to the diverse group of people of all genders, races, and international backgrounds who make up the twenty-first-century paleontology community, foregrounding their perspectives and firsthand narratives. He also frankly discusses the many challenges that face the profession, with key takeaways for aspiring scientists. Candid and comprehensive, Explorers of Deep Time is essential reading for anyone curious about the everyday work of real-life paleontologists.

A guide to long-term thinking: how to envision the far future of Earth. We live on a planet careening toward environmental collapse that will be largely brought about by our own actions. And yet we struggle to grasp the scale of the crisis, barely able to imagine the effects of climate change just ten years from now, let alone the multi-millennial timescales of Earth's past and future life span. In this book, Vincent Ialenti offers a guide for envisioning the planet's far future—to become, as he terms it, more skilled deep time reckoners. The challenge, he says, is to learn to inhabit a longer now. Ialenti takes on two overlapping crises: the Anthropocene, our current moment of human-caused environmental transformation; and the deflation of expertise—today's popular mockery and institutional erosion of expert authority. The second crisis, he argues, is worsening the effects of the first. Hearing out scientific experts who study a wider time span than a Facebook timeline is key to tackling our planet's emergency. Astrophysicists, geologists, historians, evolutionary biologists, climatologists, archaeologists, and others can teach us the art of long-termism. For a case study in long-term thinking, Ialenti turns to Finland's nuclear waste repository “Safety Case” experts. These scientists forecast far future glaciations, climate changes, earthquakes, and more, over the coming tens of thousands—or even hundreds of thousands or millions—of years. They are not pop culture “futurists” but data-driven, disciplined technical experts, using the power of patterns to construct detailed scenarios and quantitative models of the far future. This is the kind of time literacy we need if we are to survive the Anthropocene.

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.

Bioarchaeologists who study human remains in ancient, historic and contemporary settings are securely anchored within anthropology as anthropologists, yet they have not taken on the pundits the way other subdisciplines within anthropology have. Popular science authors frequently and selectively use bioarchaeological data on demography, disease, violence, migration and diet to buttress their poorly formed arguments about general trends in human behavior and health, beginning with our earliest ancestors. While bioarchaeologists are experts on these subjects, bioarchaeology and bioarchaeological approaches have largely remained invisible to the public eye. Current issues such as climate change, droughts, warfare, violence, famine, and the effects of disease are media mainstays and are subjects familiar to bioarchaeologists, many of whom have empirical data and informed viewpoints, both for topical exploration and also for predictions based on human behavior in deep time. The contributions in this volume will explore the how and where the data has been misused, present new ways of using evidence in the service of making new discoveries, and demonstrate ways that our long term interdisciplinarity lends itself to transdisciplinary wisdom. We also consider possible reasons for bioarchaeological invisibility and offer advice concerning the absolute necessity of bioarchaeologists speaking out through social media.

Humanists, scientists, and artists collaborate to address the disjunctive temporalities of ecological crisis In 2016, Antarctica’s Totten Glacier, formed some 34 million years ago, detached from its bedrock, melted from the bottom by warming ocean waters. For the editors of Timescales, this event captures the disjunctive temporalities of our era’s—the Anthropocene’s—ecological crises: the rapid and accelerating degradation of our planet’s life-supporting environment established slowly over millennia. They contend that, to represent and respond to these crises (i.e., climate change, rising sea levels, ocean acidification, species extinction, and biodiversity loss) requires reframing time itself, making more visible the relationship between past, present, and future, and between a human life span and the planet’s. Timescales’ collection of lively and thought-provoking essays puts oceanographers, geophysicists, geologists, and anthropologists into conversation with literary scholars, art historians, and archaeologists. Together forging new intellectual spaces, they explore the relationship between geological deep time and historical particularity, between ecological crises and cultural expression, between environmental policy and social constructions, between restoration ecology and future imaginaries, and between constructive pessimism and radical (and actionable) hope. Interspersed among these essays are three complementary “etudes,” in which artists describe experimental works that explore the various timescales of ecological crisis.

Depth Psychology and Climate Change offers a sensitive and insightful look at how ideas from depth psychology can move us beyond psychological overwhelm when facing the ecological disaster of climate change and its denial. Integrating ideas from disciplines including anthropology, politics, spirituality, mythology and philosophy, contributors consider how climate change affects psychological well-being and how we can place hope and radical uncertainty alongside rage and despair. The book explores symbols of transformation, myths and futures; and is structured to encourage regular reflection. Each contributor brings their own perspective – green politics, change and loss, climate change denial, consumerism and our connection to nature – suggesting responses to mental suffering arising from an unstable and uncertain international outlook. They examine how subsequent changes in consciousness can develop. This book will be essential reading for analytical psychologists, Jungian analysts and psychotherapists, as well as academics and students of Jungian and post-Jungian studies. It will also be of great interest to academics and students of the politics and policy of climate change, anthropology, myth and symbolism and ecopsychology, and to anyone seeking a new perspective on the climate emergency.

The research paper "Extinction Risk from Climate Change" published in the journal Nature in January 2004 created front-page headlines around the world. The notion that climate change could drive more than a million species to extinction captured both the popular imagination and the attention of policy-makers, and provoked an unprecedented round of scientific critique. Saving a Million Species reconsiders the central question of that paper: How many species may perish as a result of climate change and associated threats? Leaders from a range of disciplines synthesize the literature, refine the original estimates, and elaborate the conservation and policy implications. The book: examines the initial extinction risk estimates of the original paper, subsequent critiques, and the media and policy impact of this unique study presents evidence of extinctions from climate change from different time frames in the past explores extinctions documented in the contemporary record sets forth new risk estimates for future climate change considers the conservation and policy implications of the estimates. Saving a Million Species offers a clear explanation of the science behind the headline-grabbing estimates for conservationists, researchers, teachers, students, and policy-makers. It is a critical resource for helping those working to conserve biodiversity take on the rapidly advancing and evolving global stressor of climate change-the most important issue in conservation biology today, and the one for which we are least prepared.
