Available in PDF, EPUB and Kindle. Book excerpt: The Middle Holocene epoch (8,000 to 3,000 years ago) was a time of dramatic changes in the physical world and in human cultures. Across this span, climatic conditions changed rapidly, with cooling in the high to mid-latitudes and drying in the tropics. In many parts of the world, human groups became more complex, with early horticultural systems replaced by intensive agriculture and small-scale societies being replaced by larger, more hierarchial organizations. Climate Change and Cultural Dynamics explores the cause and effect relationship between climatic change and cultural transformations across the mid-Holocene (c. 4000 B.C.). Explores the role of climatic change on the development of society around the world Chapters detail diverse geographical regions Co-written by noted archaeologists and paleoclimatologists for non-specialists

Download or read book Global Change in the Holocene written by John Birks and published by Routledge. This book was released on 2014-02-24 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Holocene spans the 11,500 years since the end of the last Ice Age and has been a period of major global environmental change. However the rate of change has accelerated during the last hundred years, due largely to human impacts and this has led to a growing concern for the future of our environmental resources. Global Change in the Holocene demonstrates how reconstructing the record of past environmental change can provide us with essential knowledge about how our environment works and presents the reader with an informed viewpoint from which to project realistic future scenarios. The book brings together key techniques that are widely used in Holocene research, such as radiocarbon dating, dendrochronology and sediment analysis and offers a comprehensive analysis of various archives of environmental change including instrumental and documentary records, corals, lake sediments, glaciers and ice cores. This reference will be an informative and cutting-edge resource for all researchers in the fields of climate change, environmental science, geography, palaeoecology and archaeology.

Download or read book Historical Environmental Variation in Conservation and Natural Resource Management written by John A. Wiens and published by John Wiley & Sons. This book was released on 2012-07-09 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: In North America, concepts of Historical Range of Variability are being employed in land-management planning for properties of private organizations and multiple government agencies. The National Park Service, U.S. Fish & Wildlife Service, Bureau of Land Management, U.S. Forest Service, and The Nature Conservancy all include elements of historical ecology in their planning processes. Similar approaches are part of land management and conservation in Europe and Australia. Each of these user groups must struggle with the added complication of rapid climate change, rapid land-use change, and technical issues in order to employ historical ecology effectively. Historical Environmental Variation in Conservation and Natural Resource Management explores the utility of historical ecology in a management and conservation context and the development of concepts related to understanding future ranges of variability. It provides guidance and insights to all those entrusted with managing and conserving natural resources: land-use planners, ecologists, fire scientists, natural resource policy makers, conservation biologists, refuge and preserve managers, and field practitioners. The book will be particularly timely as science-based management is once again emphasized in United States federal land management and as an understanding of the potential effects of climate change becomes more widespread among resource managers.

Download or read book Holocene Climate Change and Climate Variability in the Northeastern United States and Northwestern China written by Cheng Zhao and published by . This book was released on 2009 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Holocene climate change is still poorly understood in many parts of world. Here, I present multi-proxy records from sediments at three lakes in the northeastern United States and northwestern China to investigate the nature of Holocene climate change and climate variability. Chapter 1 presents a 35-year resolution calcite delta18O record for the last 12 ka (1ka=1000 cal yr BP) from Lake Grinnell in northern New Jersey. The record suggests that the delta18O shift from a stable state to a steadily decreasing trend at 5.8 ka reflects a non-linear response of atmospheric circulation to the gradual decrease in insolation, and that a dominant frequency shift in solar forcing might have caused the shift of centennial-scale climate oscillations in amplitude and frequency. Chapter 2 provides a 2-year resolution calcite delta18O record from a freeze-core at White Lake in northern New Jersey. The delta 18O changes, together with the published paleosalinity reconstructions from Chesapeake Bay, show a dry climate at 1780-1850, a wet climate at 1850-1920, and ~20-year moisture oscillations after 1920. Regional atmospheric circulation and Atlantic Multidecadal Oscillation may control the observed moisture variations. Anthropogenic global warming could be responsible for the increased moisture variability since 1920. Chapter 3 presents high-resolution lake-level records for the last 8 ka from Hurleg Lake on the northeastern Tibetan Plateau. Consistent with the East Asian and Indian monsoon reconstructions, the data show a dry and highly variable climate from 7.8 to 1 ka and a stable and wet climate after1 ka. Six dry intervals at 7.6-7.2 ka, 6.2-5.9 ka, 5.3-4.9 ka, 4.4-3.8 ka, 2.7-2.4 ka and 1.7-1.1 ka have also been detected. Insolation, solar variations, and/or oceanic and atmospheric circulations are responsible for the monsoon changes and millennial-scale variability. Chapter 4 provides a centennial-scale lake-level record for the past 1 ka at Hurleg Lake. The opposite moisture pattern between the Qaidam Basin and surrounding mountains implies that topography could be an important factor in controlling regional moisture patterns through mediating rising and subsidence air masses in this topographically-complex region. The 200-year moisture oscillations were possibly caused by change in solar forcing.

This book was released on 2015-04-03 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an update of the first BACC assessment, published in 2008. It offers new and updated scientific findings in regional climate research for the Baltic Sea basin. These include climate changes since the last glaciation (approx. 12,000 years ago), changes in the recent past (the last 200 years), climate projections up until 2100 using state-of-the-art regional climate models and an assessment of climate-change impacts on terrestrial, freshwater and marine ecosystems. There are dedicated new chapters on sea-level rise, coastal erosion and impacts on urban areas. A new set of chapters deals with possible causes of regional climate change along with the global effects of increased greenhouse gas concentrations, namely atmospheric aerosols and land-cover change. The evidence collected and presented in this book shows that the regional climate has already started to change and this is expected to continue. Projections of potential future climates show that the region will probably become considerably warmer and wetter in some parts, but dryer in others. Terrestrial and aquatic ecosystems have already shown adjustments to increased temperatures and are expected to undergo further changes in the near future. The BACC II Author Team consists of 141 scientists from 12 countries, covering various disciplines related to climate research and related impacts. BACC II is a project of the Baltic Earth research network and contributes to the World Climate Research Programme.

Download or read book The Spatial and Temporal Evolution of Holocene Climates in North America and Europe written by Jeremiah P. Marsicek and published by . This book was released on 2016 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding what drives temperature changes on regional- to hemispheric-scales is a long-standing question in paleoclimatology. More recently, the climate community has been alerted to the issue of a data-model temperature disagreement (known as the ‘Holocene Temperature Conundrum’) over the last 11,000 years. A recent marine-based temperature reconstruction showed temperatures cooling, while models showed temperatures warming over the last 11,000 years. My work investigates what caused long-term and millennial-scale changes in temperature in the northern mid-latitudes during the Holocene, and how those changes fit with the Holocene Temperature Conundrum. First, I investigated what the dominant patterns of Holocene temperature change were across North America and Europe. I consider whether long-term trends differ from those observed in marine temperature records. Using a modern pollen-climate calibration dataset spanning both continents, I applied the modern analog technique (MAT) to a network of >1600 fossil pollen records. I used the best available calibrated radiocarbon chronologies, accounted for spatial biases in the distribution of sites by calculating mean reconstructions for all 2° x 2° geographic windows, and accounted for local ecological effects and chronological uncertainties by iteratively generating 100 reconstructions for each geographic window after averaging randomly selected sets of records. Time series and maps show both long-term temperature trends and regional variability at centennial-to-millennial scales. While the long-term trends are different between my continent-based temperature reconstruction and the marine-based temperature record, when detrended, I find replicated millennial-scale variability. Next, a principal components analysis highlighted that ice sheet area and insolation were the most important factors driving long-term temperature trends across North America and Europe, and that the most important factor driving millennial-scale climate variability, while weak, may be feedbacks among intrinsically varying components of the climate system. Finally, I examined regional-scale patterns of regional temperature variability during the Holocene. By applying the MAT to fossil pollen data from a transect of the 15 best-resolved records from the Rocky Mountains to New England, I reconstructed summer temperatures to study the spatial patterns of abrupt change in the mid-Holocene apparent in the multi-continent analyses. I find that an abrupt change at ca. 5,000 years ago is expressed across mid-latitude North America with cooling in some regions coinciding with evidence for warming elsewhere. This analysis highlights that temperatures during the Holocene were not much warmer than today, ice sheet area is the single most important factor controlling Holocene temperatures, millennial-scale variability is replicated in marine and my continental temperature datasets, and that the possibility for state shifts in the climate system exists, such as at 5,000 years ago.
