Climate Change And Ecosystems

Human-driven greenhouse emissions are increasing the velocity of climate change and the frequency and intensity of climate extremes far above historical levels. These changes, along with other human-perturbations, are setting the conditions for more rapid and abrupt ecosystem dynamics and collapse. This book presents new evidence on the rapid emergence of ecosystem collapse in response to the progression of anthropogenic climate change dynamics that are expected to intensify as the climate continues to warm. Discussing implications for biodiversity conservation, the chapters provide examples of such dynamics globally covering polar and boreal ecosystems, temperate and semi-arid ecosystems, as well as tropical and temperate coastal ecosystems. Given its scope, the volume appeals to scientists in the fields of general ecology, terrestrial and coastal ecology, climate change impacts, and biodiversity conservation.

This book is the result of a team of approximately 100 scientists and resource managers who worked together for two years to understand the effects of climatic variability and change on water resources, fisheries, forest vegetation, non-forest vegetation, wildlife, recreation, cultural resources and ecosystem services. Adaptation options, both strategic and tactical, were developed for each resource area. This information is now being applied in the northern rocky Mountains to ensure long-term sustainability in resource conditions. The volume chapters provide a technical assessment of the effects of climatic variability and change on natural and cultural resources, based on best available science, including new analyses obtained through modeling and synthesis of existing data. Each chapter also contains a summary of adaptation strategies (general) and tactics (on-the-ground actions) that have been developed by science-management teams.

Featuring contributions from leading experts in the field, Climate Change and Managed Ecosystems examines the effects of global climate change on intensively constructed or reconstructed ecosystems, focusing on land use changes in relation to forestry, agriculture, and wetlands including peatlands. The book begins by discussing the fragility of eco

Global climate change is a certainty. The Earth's climate has never remained static for long and the prospect for human-accelerated climate change in the near future appears likely. Freshwater systems are intimately connected to climate in several ways: they may influence global atmospheric processes affecting climate; they may be sensitive early indicators of climate change because they integrate the atmospheric and terrestrial events occurring in their catchments; and, of course, they will be affected by climate change. An improved predictive understanding of environmental effects on pattern and process in freshwater ecosystems will be invaluable as a baseline upon which to build sound protection and management policies for fresh waters. This book represents an early step towards this improved understanding. The contributors accepted the challenge to assume global warming of 2-5oC in the next century. They then explored the implications of this scenario on various freshwater ecosystems and processes. To provide a broader perspective, Firth and Fisher included several chapters which do not deal expressly with freshwater ecosystems, but rather discuss climate change in terms of causes and mechanisms, implications for water resources, and the use of remote sensing as a tool for expanding studies from local to global scale.

Take a provocative look at how human activities affect the distribution of species and their critical habitats, increase the occurrence of severe weather and droughts, contribute to rising sea levels, and instigate myriad health and quality-of-life issues.

Climate change poses many challenges that affect society and the natural world. With these challenges, however, come opportunities to respond. By taking steps to adapt to and mitigate climate change, the risks to society and the impacts of continued climate change can be lessened. The National Climate Assessment, coordinated by the U.S. Global Change Research Program, is a mandated report intended to inform response decisions. Required to be developed every four years, these reports provide the most comprehensive and up-to-date evaluation of climate change impacts available for the United States, making them a unique and important climate change document. The draft Fourth National Climate Assessment (NCA4) report reviewed here addresses a wide range of topics of high importance to the United States and society more broadly, extending from human health and community well-being, to the built environment, to businesses and economies, to ecosystems and natural resources. This report evaluates the draft NCA4 to determine if it meets the requirements of the federal mandate, whether it provides accurate information grounded in the scientific literature, and whether it effectively communicates climate science, impacts, and responses for general audiences including the public, decision makers, and other stakeholders.

Climate Change and Agricultural Ecosystems explains the causative factors of climate change related to agriculture, soil and plants, and discusses the relevant resulting mitigation process. Agricultural ecosystems include factors from the surrounding areas where agriculture experiences direct or indirect interaction with the plants, animals, and microbes present. Changes in climatic conditions influence all the factors of agricultural ecosystems, which can potentially adversely affect their productivity. This book summarizes the different aspects of vulnerability, adaptation, and amelioration of climate change in respect to plants, crops, soil, and microbes for the sustainability of the agricultural sector and, ultimately, food security for the future. It also focuses on the utilization of information technology for the sustainability of the agricultural sector along with the capacity and adaptability of agricultural societies under climate change. Climate Change and Agricultural Ecosystems incorporates both theoretical and practical aspects, and serves as base line information for future research. This book is a valuable resource for those working in environmental sciences, soil sciences, agricultural microbiology, plant pathology, and agronomy. Covers the role of chemicals fertilizers, environmental deposition, and xenobiotics in climate change Discusses the impact of climate change on plants, soil, microflora, and agricultural ecosystems Explores the mitigation of climate change by sustainable methods Presents the role of computational modelling in climate change mitigation

Tropical ecosystems - the regions between the tropics of Cancer and Capricorn - play an important role in global processes, economic issues, and political concerns. In their natural state, tropical ecosystems support a large quantity of above- and below-ground biomass, and constitute a major part of the terrestrial carbon pool. Conversion of the natural ecosystem to agriculture and forestry ecosystems disturbs this ecological balance. Global Climate Change and Tropical Ecosystems presents data on carbon pool fluxes from case studies in 12 countries in tropical regions. The chapters cover: Characteristics of tropical ecosystems Soil and biotic carbon pools Impacts of land use and soil management Slash-and-burn practices Crop residue and fertility management This volume adds to the understanding of pedospheric processes in tropical ecosystems and how to better use soils as a sink for carbon dioxide and other greenhouse gases. With Global Climate Change and Tropical Ecosystems you will understand the link between soil productivity, environmental quality and the global carbon cycle, not only in these ecologically sensitive regions but worldwide.
