Book Description
North America in the Anthropocene maintains that human beings have entered a new historical epoch--the Anthropocene--in which our own economic activity has reached such planetary scale and power that we can no longer count on Earth's natural systems and functions to absorb negative human impacts on landscape and biodiversity. Whether we like it or not, we have to assume responsibility for staying within Earth-system boundaries. Climate stability is only one of those boundaries, but it is a critical one. This book attempts to address the question of why, when we clearly know the enormous risks we face, we are still not doing what is necessary to prevent climate disaster. The author introduces contemporary thinking by leading philosophers, ethicists and social scientists who do not believe that more information and greater individual thoughtfulness are necessarily going to be adequate to penetrate the thick skin of the status quo when it comes to addressing the climate threat.

Book Description
In the first book devoted exclusively to the ecopoetics of the twenty-first century, Lynn Keller examines poetry of what she terms the "self-conscious Anthropocene," a period in which there is widespread awareness of the scale and severity of human effects on the planet. Recomposing Ecopoetics analyzes work written since the year 2000 by thirteen North American poets--including Evelyn Reilly, Juliana Spahr, Ed Roberson, and Jena Osman--all of whom push the bounds of literary convention as they seek forms and language adequate to complex environmental problems. Drawing as often on linguistic experimentalism as on traditional literary resources, these poets respond to environments transformed by people and take "nature" to be a far more inclusive and culturally imbricated category than conventional nature poetry does. This interdisciplinary study not only brings cutting-edge work in ecocriticism to bear on a diverse archive of contemporary environmental poetry; it also offers the environmental humanities new ways to understand the cultural and affective dimensions of the Anthropocene.

Book Description
Earth now is dominated by both biogeophysical and anthropogenic processes, as represented in these two images from a simulation of aerosols. Dust (red) from the Sahara sweeps west across the Atlantic Ocean. Sea salt (blue) rises into the atmosphere from winds over the North Atlantic and from a tropical cyclone in the Indian Ocean. Organic and black carbon (green) from biomass burning is notable over the Amazon and Southeast Asia. Plumes of sulfate (white) from fossil fuel burning are particularly prominent over northeastern North America and East Asia. If present trends of dust emissions and fossil fuel burning continues in what we call the Anthropocene epoch, then we could experience high atmospheric CO2 levels leading to unusual warming rarely experienced in Earth's history. This book focuses on human influences on land, ocean, and the atmosphere, to determine if human activities are operating within or beyond the safe zones of our planet's biological, chemical, and physical systems. Volume highlights include: Assessment of civic understanding of Earth and its future Understanding the role of undergraduate geoscience research and community-driven research on the Anthropocene Effective communication of science to a broader audience that would include the public, the K-12 science community, or populations underrepresented in the sciences Public outreach on climate education, geoscience alliance, and scientific reasoning Future Earth is a valuable practical guide for scientists from all disciplines including geoscientists, museum curators, science educators, and public policy makers.

Book Description
This book provides a conceptually organized framework to understand the phenomenon of biological invasions at the Anthropocene global scale. Most advances toward that aim have been provided from North American and European researchers, with fewer contributions from Australia and South Africa. Here we fill the void from the Neotropics, focusing on the research experience in South American countries, with a strong emphasis on Argentina and Chile. The text is divided into two parts: The first half comprises self-contained chapters, providing a conceptual, bibliographic and empirical foundation in the field of invasion biology, from an Anthropocene perspective. The second half reviews the ecology, biogeography, and local impacts in South America of exotic species groups (European rabbit, Eurasian wild boar, Canadian beaver, North American mink, and Holarctic freshwater fishes), which are shown to be useful models for case studies of global relevance.

Book Description
The assumption that prehistoric Native American land use practices had little impact on the North American landscape persists in the literature. However, recent research suggests the effects of prehistoric burning, deforestation and agriculture may potentially have been greater than previously considered. To resolve this discrepancy, quantitative estimates of changes in human population size and forest structure and composition over the course of the Holocene are needed. This thesis addresses this need by providing radiocarbon-based paleodemographic reconstructions and pollen-inferred estimates of vegetation change, as well as analyses of associations between the two at both continental and regional scales, from the late Pleistocene to the Anthropocene. One way to estimate paleodemographic change is to use the number of radiocarbon (14C) dates from a given area to study patterns of human occupation through time. A review of the literature and compilation of existing databases relevant to this method showed there is now sufficient data to study the paleodemographic history of many regions around the world. An analysis of 14C datasets from North America and Australia compared well with model-based reconstructions of past demographic growth, and provided higher frequency fluctuations in population densities that will be important for future research. Using a kernel density estimation approach, the first estimates of prehistoric population density for North America were obtained and synthesized into a series of continental-scale maps showing the distribution and frequency of 14C dates in the Canadian Archaeological Radiocarbon Database (CARD). The maps illustrated the space-time evolution of population and migration patterns, which were corroborated by independent sources of evidence. A methodology based on the statistical evaluation of cross-correlations between population and plant abundance was then developed to analyze the associations between these population estimates and plant communities derived from pollen databases. Periods of high spatial cross-correlation (positive and negative) between population and plant abundance were irregular and did not improve over time, suggesting that ancient human impacts are not discernable at a continental scale, either due to low populations or varying human land use practices. To further examine the relationship between pollen data and human land use at a regional scale, estimates of plant density and landscape openness are needed. The REVEALS (Regional Estimates of VEgetation Abundance from Large Sites) model corrects for the non-linear relationship between pollen production and plant abundance and can therefore be used to map histories of land use and land cover change. The model was applied to pollen records from lake sediments in the deciduous forest of southeastern Quebec. A preliminary analysis comparing these results to population density revealed low population during times of high Populus abundance and high population following the appearance of the mixed temperate forest suggesting a discernable human-environment association at regional scales. Overall, the results of thesis support the growing body of literature that suggests prehistoric Native Americans impacted their environments and that these impacts can be detected and quantified by integrating archaeological and paleoecological information. However, the timing, location, and intensity of human land use has changed in both space and time, suggesting regional- to local-scale analyses of human-environment interactions are most appropriate for continental North America. The methodology presented here can be used to study additional North American regions for the purpose of developing a continental history of human-environment interaction.

Book Description
Climate change and anthropogenic alterations of the landscape like non-native species introduction, pollution, and habitat destruction substantially alter ecosystem functioning through shifts in key phenological events and changes in community composition as certain species and groups of species decrease in abundance and distribution. Alterations in the timing of flowering and leaf phenology have been observed worldwide but the dearth of long-term observational records limits assessment of phenological responsiveness in many regions and for many species. Similarly, there is insufficient observational data regarding the occurrences of the majority of described species to assess changes in population abundance or distribution over time. Thus, the conservation needs of these species cannot be assessed. To address these knowledge and data gaps, I used herbarium specimens as a non-traditional data source to develop a novel method for quantifying flowering shifts with temperature increase, to evaluate flowering responsiveness to temperature in 207 plant species in Ohio, and to determine changes in abundance and distribution of those species over the past 115 year. Further, I used one of the most comprehensive historic leaf phenology datasets in the world paired with modern observations to determine changes in total growing season length and to model spring and autumn leaf phenology using temperature and precipitation drivers.

Book Description
Once ice-bound, difficult to access, and largely ignored by the rest of the world, the Arctic is now front and center in the midst of many important questions facing the world today. Our daily weather, what we eat, and coastal flooding are all interconnected with the future of the Arctic. The year 2012 was an astounding year for Arctic change. The summer sea ice volume smashed previous records, losing approximately 75 percent of its value since 1980 and half of its areal coverage. Multiple records were also broken when 97 percent of Greenland's surface experienced melt conditions in 2012, the largest melt extent in the satellite era. Receding ice caps in Arctic Canada are now exposing land surfaces that have been continuously ice covered for more than 40,000 years. What happens in the Arctic has far-reaching implications around the world. Loss of snow and ice exacerbates climate change and is the largest contributor to expected global sea level rise during the next century. Ten percent of the world's fish catches comes from Arctic and sub-Arctic waters. The U.S. Geological Survey estimated that up to 13 percent of the world's remaining oil reserves are in the Arctic. The geologic history of the Arctic may hold vital clues about massive volcanic eruptions and the consequent release of massive amount of coal fly ash that is thought to have caused mass extinctions in the distant past. How will these changes affect the rest of Earth? What research should we invest in to best understand this previously hidden land, manage impacts of change on Arctic communities, and cooperate with researchers from other nations? The Arctic in the Anthropocene reviews research questions previously identified by Arctic researchers, and then highlights the new questions that have emerged in the wake of and expectation of further rapid Arctic change, as well as new capabilities to address them. This report is meant to guide future directions in U.S. Arctic research so that research is targeted on critical scientific and societal questions and conducted as effectively as possible. The Arctic in the Anthropocene identifies both a disciplinary and a cross-cutting research strategy for the next 10 to 20 years, and evaluates infrastructure needs and collaboration opportunities. The climate, biology, and society in the Arctic are changing in rapid, complex, and interactive ways. Understanding the Arctic system has never been more critical; thus, Arctic research has never been more important. This report will be a resource for institutions, funders, policy makers, and students. Written in an engaging style, The Arctic in the Anthropocene paints a picture of one of the last unknown places on this planet, and communicates the excitement and importance of the discoveries and challenges that lie ahead.

Book Description
Allow yourself to be taken back into deep geologic time when strange creatures roamed the Earth and Western North America looked completely unlike the modern landscape. Volcanic islands stretched from Mexico to Alaska, most of the Pacific Rim didn’t exist yet, at least not as widespread dry land; terranes drifted from across the Pacific to dock on Western Americas’ shores creating mountains and more volcanic activity. Landscapes were transposed north or south by thousands of kilometers along huge fault systems. Follow these events through paleogeographic maps that look like satellite views of ancient Earth. Accompanying text takes the reader into the science behind these maps and the geologic history that they portray. The maps and text unfold the complex geologic history of the region as never seen before. Winner of the 2021 John D. Haun Landmark Publication Award, AAPG-Rocky Mountain Section

Book Description
Forest Conservation in the Anthropocene provides thought-provoking insight into the ongoing environmental crises that climate change is generating and raises critical questions about how public and private land managers in North America will adapt to the climatological disruptions that are already transforming the ecological structures of these forests. In this pathbreaking anthology, a team of leading environmental researchers probes the central dilemmas that ecologists, forest land managers, state and federal agencies, and grassroots organizations are confronting—and will continue to confront—in the coming century. Each chapter examines strategies that are currently being tested across the country as scientists, citizen-scientists, policy makers, academics, and activists work to grasp their options and opportunities for a future that will be shaped by ongoing environmental upheaval. Successful adaptation to the challenges of climate change requires a transdisciplinary perspective. Forest Conservation in the Anthropocene provides a compelling set of arguments and case studies that underscores the need for innovative policies and energetic actions. Contributors: Craig D.
