Paleoclimatology by Gilles Ramstein,Amaëlle Landais,Nathaelle Bouttes,Pierre Sepulchre,Aline Govin Pdf

This two-volume book provides a comprehensive, detailed understanding of paleoclimatology beginning by describing the “proxy data” from which quantitative climate parameters are reconstructed and finally by developing a comprehensive Earth system model able to simulate past climates of the Earth. It compiles contributions from specialists in each field who each have an in-depth knowledge of their particular area of expertise. The first volume is devoted to “Finding, dating and interpreting the evidence”. It describes the different geo-chronological technical methods used in paleoclimatology. Different fields of geosciences such as: stratigraphy, magnetism, dendrochronology, sedimentology, are drawn from and proxy reconstructions from ice sheets, terrestrial (speleothems, lakes, and vegetation) and oceanic data, are used to reconstruct the ancient climates of the Earth. The second volume, entitled “Investigation into ancient climates,” focuses on building comprehensive models of past climate evolution. The chapters are based on understanding the processes driving the evolution of each component of the Earth system (atmosphere, ocean, ice). This volume provides both an analytical understanding of each component using a hierarchy of models (from conceptual to very sophisticated 3D general circulation models) and a synthetic approach incorporating all of these components to explore the evolution of the Earth as a global system. As a whole this book provides the reader with a complete view of data reconstruction and modeling of the climate of the Earth from deep time to present day with even an excursion to include impacts on future climate.

Principles of Paleoclimatology by Thomas M. Cronin Pdf

Greenhouse gases, global warming, thinning ozone layers—understanding the Earth's climatic changes is one of today's most pressing international concerns. How fast has the climate changed? Where and why is it changing? What is the impact of climate change on our ecosystems, coastal regions, glaciers, forests, and lakes, and even on the evolution of our own species? This introduction to the rapidly emerging field of paleoclimatology explains the patterns and processes in the history of the Earth's climate to answer such essential questions. Using the geologic records of ocean and lake sediment, ice cores, corals, and other natural archives, Principles of Paleoclimatology describes the history of the Earth's climate—the ice age cycles, sea level changes, volcanic activity, changes in atmosphere and solar radiation—and the resulting, sometimes catastrophic, biotic responses. These paleoclimate records provide a baseline against which we can compare modern climate trends. Designed to give a fundamental background—including both history and methodology—to the discipline of paleoclimatology, this book is the first to advance our understanding of how climate change develops, how those changes are detected, and how the climate of the past can shape the climate of the future.

Paleoclimatology by Colin P. Summerhayes Pdf

Life on our planet depends upon having a climate that changes within narrow limits – not too hot for the oceans to boil away nor too cold for the planet to freeze over. Over the past billion years Earth’s average temperature has stayed close to 14-15°C, oscillating between warm greenhouse states and cold icehouse states. We live with variation, but a variation with limits. Paleoclimatology is the science of understanding and explaining those variations, those limits, and the forces that control them. Without that understanding we will not be able to foresee future change accurately as our population grows. Our impact on the planet is now equal to a geological force, such that many geologists now see us as living in a new geological era – the Anthropocene. Paleoclimatology describes Earth’s passage through the greenhouse and icehouse worlds of the past 800 million years, including the glaciations of Snowball Earth in a world that was then free of land plants. It describes the operation of the Earth’s thermostat, which keeps the planet fit for life, and its control by interactions between greenhouse gases, land plants, chemical weathering, continental motions, volcanic activity, orbital change and solar variability. It explains how we arrived at our current understanding of the climate system, by reviewing the contributions of scientists since the mid-1700s, showing how their ideas were modified as science progressed. And it includes reflections based on the author’s involvement in palaeoclimatic research. The book will transform debate and set the agenda for the next generation of thought about future climate change. It will be an invaluable course reference for undergraduate and postgraduate students in geology, climatology, oceanography and the history of science.

Limnology, Climatology and Paleoclimatology of the East African Lakes by Thomas C Johnson,Eric O Odada Pdf

The large lakes of the East African Rift Valley are among the oldest on Earth, and are vital resources for the people of their basins. They are unique among the large lakes of the world in terms of their sensitivity to climatic change, rich and diverse populations of endemic species, circulation dynamics and water-column chemistry, and long, continuous records of past climatic change. A comprehensive study of the large African lakes is long overdue. The scientific justification for such an effort is noted in the previous paragraph and is illustrated in great detail in this volume. Societal need for the sustainable utilization of these lakes offers an even more compelling reason for examination of biological food webs, water quality, and past climate variability in East Africa. The lakes provide the most important source of protein for the people of the African Rift Valley, and fish populations are shifting dramatically in response to fishing pressure, introduction of exotic species, land use impact on water quality, and perhaps climatic change. Current estimates of primary productivity, the underpinning of the food resource, are extremely crude and based on only a few spot measurements.

Late Neogene Chronostratigraphy, Biostratigraphy, Biochronology and Paleoclimatology by William A. Berggren,John A.. Van Couvering Pdf

The integration of modern paleomagnetic, radiometric, and biostratigraphic studies has provided an accurate geochronological framework for the past 10 million years--the Late Neogene. Marine zones based on calcareous and siliceous planktonic organisms are recognized from the sub-Arctic region to the sub-Antarctic and their correlation to the paleomagnetic time scale is now feasible in some detail for the past 5 my. Likewise, the relationship of geochemically calibrated mammalian biochronology to the marine succession has been greatly improved. Within this framework of time it is possible to delineate the history of major features in Late Neogene paleontology, climatology, and oceanography. (Author).

Paleoclimatology and Paleometeorology: Modern and Past Patterns of Global Atmospheric Transport by Margaret Leinen,Michael Sarnthein Pdf

The NATO Advanced Research Workshop on "Paleoclimatology and Paleometeorology: Modem and Past Patterns of Global Atmospheric Transport" (held at Oracle, Arizona, USA from November 17-19, 1987) brought together atmospheric chemists, physicists, and meteorologists who study the origin and transport of modem-day mineral and biological aerosols with geologists and paleobotanists who study the sedimentary record of eolian and hydrologic processes along with modelers who study and conceptualize the processes influencing atmospheric transport at present and in the past. Presentations at the workshop provided a guide to our present knowledge of the entire spectrum of processes and phenomena important to the generation, transport, and deposition of eolian terrigenous material that ultimately becomes part of the geologic record and the modeling techniques that used to represent these processes. The presenta tions on the geologic record of eolian deposition documented our present understanding of the na~e and causes of climate change on time scales of the last glacial ages (tens of thousands of years) to time scales over which the arrangement of continents, mountains, and oceans has changed sub stantially (tens of millions of years). There has been a growing recognition of the importance of global climatic changes to the future well-being of humanity. In particular, the climatic response to human alterations to the earth's surface and chemical composition has led to concern over the agricultural, ecological, and societal impacts of such potential global changes.

Boron Proxies in Paleoceanography and Paleoclimatology by Bärbel Hönisch,Stephen M. Eggins,Laura L. Haynes,Katherine A. Allen,Katherine D. Holland,Katja Lorbacher Pdf

Anthropogenic carbon dioxide emissions do not only warm our planet but also acidify our oceans. It is currently unclear to which degree Earth’s climate and marine life will be impacted by these changes but information from Earth history, particularly the geochemical signals of past environmental changes stored in the fossil remains of marine organisms, can help us predict possible future changes. This book aims to be a primer for scientists who seek to apply boron proxies in marine carbonates to estimate past seawater carbonate chemistry and atmospheric pCO2. Boron proxies (δ11B and B/Ca) were introduced nearly three decades ago, with subsequent strides being made in understanding their mechanistic functioning. This text reviews current knowledge about the aqueous systematics, the inorganic and biological controls on boron isotope fractionation and incorporation into marine carbonates, as well as the analytical techniques for measurement of boron proxies. Laboratory and field calibrations of the boron proxies are summarized, and similarities between modern calibrations are explored to suggest estimates for proxy sensitivities in marine calcifiers that are now extinct. Example applications illustrate the potential for reconstructing paleo-atmospheric pCO2 from boron isotopes. Also explored are the sensitivity of paleo-ocean acidity and pCO2 reconstructions to boron isotope proxy systematics that are currently less well understood, including the elemental and boron isotopic composition of seawater through time, seawater alkalinity, temperature and salinity, and their collective impact on the uncertainty of paleo-reconstructions. The B/Ca proxy is based on the same mechanistic principles as the boron isotope proxy, but empirical calibrations suggest seawater pH is not the only controlling factor. B/Ca therefore has the potential to provide a second carbonate parameter that could be paired with δ11B to fully constrain the ocean carbonate system, but the associated uncertainties are large. This text reviews and examines what is currently known about the B/Ca proxy systematics. As more scientists embark on characterizing past ocean acidity and atmospheric pCO2, Boron in Paleoceanography and Paleoclimatology provides a resource to introduce geoscientists to the opportunities and complications of boron proxies, including potential avenues to further refine them.

Laminated Lake Sediments and their Impact on Paleoclimatology by Eric Petermann Pdf

Seminar paper from the year 2008 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 1,0, University of Canterbury (Department of Geology), course: Paleoecology and Paleolimnology, language: English, abstract: Zolitschka (1998) defined varves as laminated sediments occurring in stationary water bodies. Their striking feature is a seasonal, rhythmical build-up of thin, horizontal layers with a changing composition. Since the early 20th century, this type of sediment has been used for establishing exact geochronologies. In the course of the climate change debate, and the subsequent demand for high-resolution paleoclimatic data, they have come back into the focus of earth scientists. A crucial advantage of varved sediments is that they provide two different kinds of information on a sediment profile: an absolute chronology and high-resolution paleoclimatic information. Combining these two attributes offers an absolute dated time series of paleoclimatic proxy-data. Furthermore, additional analyses of the same profile can be dated. Varved sediments can be found in recent lakes as well as in paleolakes. However, their occurrence is limited to only a few sites as a consequence of the special circumstances necessary for their generation. Varved sediments in recent lakes are especially found in lakes, which are small and deep. These preconditions are often met by maars, where a lot of investigations are done (Brauer et al. 1999a, 1999b; Litt et al. 2001). Additionally, varved sediments are even found in ancient proglacial lakes (Moscariello et al. 2000) to give an example.
