Available in PDF, EPUB and Kindle. Book excerpt: Deciphering the evolution of global climate from the end of the Last Glacial Maximum approximately 19 ka to the early Holocene 11 ka presents an outstanding opportunity for understanding the transient response of Earth's climate system to external and internal forcings. During this interval of global warming, the decay of ice sheets caused global mean sea level to rise by approximately 80 m; terrestrial and marine ecosystems experienced large disturbances and range shifts; perturbations to the carbon cycle resulted in a net release of the greenhouse gases CO2 and CH4 to the atmosphere; and changes in atmosphere and ocean circulation affected the global distribution and fluxes of water and heat. Here we summarize a major effort by the paleoclimate research community to characterize these changes through the development of well-dated, high-resolution records of the deep and intermediate ocean as well as surface climate. Our synthesis indicates that the superposition of two modes explains much of the variability in regional and global climate during the last deglaciation, with a strong association between the first mode and variations in greenhouse gases, and between the second mode and variations in the Atlantic meridional overturning circulation.

Download or read book Earth s Climate Evolution written by Colin P. Summerhayes and published by John Wiley & Sons. This book was released on 2015-10-19 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: To understand climate change today, we first need to know how Earth’s climate changed over the past 450 million years. Finding answers depends upon contributions from a wide range of sciences, not just the rock record uncovered by geologists. In Earth’s Climate Evolution, Colin Summerhayes analyzes reports and records of past climate change dating back to the late 18th century to uncover key patterns in the climate system. The book will transform debate and set the agenda for the next generation of thought about future climate change. The book takes a unique approach to the subject providing a description of the greenhouse and icehouse worlds of the past 450 million years since land plants emerged, ignoring major earlier glaciations like that of Snowball Earth, which occurred around 600 million years ago in a world free of land plants. It describes the evolution of thinking in palaeoclimatology and introduces the main players in the field and how their ideas were received and, in many cases, subsequently modified. It records the arguments and discussions about the merits of different ideas along the way. It also includes several notes made from the author’s own personal involvement in palaeoclimatological and palaeoceanographic studies, and from his experience of working alongside several of the major players in these fields in recent years. This book will be an invaluable reference for both undergraduate and postgraduate students taking courses in related fields and will also be of interest to historians of science and/or geology, climatology and oceanography. It should also be of interest to the wider scientific and engineering community, high school science students, policy makers, and environmental NGOs. Reviews: "Outstanding in its presentation of the facts and a good read in the way that it intersperses the climate story with the author's own experiences. [This book] puts the climate story into a compelling geological history." -Dr. James Baker "The book is written in very clear and concise prose, [and takes] original, enlightening, and engaging approach to talking about 'ideas' from the perspective of the scientists who promoted them." -Professor Christopher R. Scotese "A thrilling ride through continental drift and its consequences." - Professor Gerald R. North "Written in a style and language which can be easily understood by laymen as well as scientists." - Professor Dr Jörn Thiede "What makes this book particularly distinctive is how well it builds in the narrative of change in ideas over time." - Holocene book reviews, May 2016 "This is a fascinating book and the author’s biographical approach gives it great human appeal." - E Adlard

Download or read book Second Assessment of Climate Change for the Baltic Sea Basin written by The BACC II Author Team and published by Springer. 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 Iberia Land of Glaciers written by Marc Oliva and published by Elsevier. This book was released on 2021-09-22 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iberia, Land of Glaciers: How The Mountains Were Shaped By Glaciers discusses the impact of past glaciers in the current landscape of Iberia. Currently, there are only small glaciers in the highest peaks of the Pyrenees that are the legacy of the last cold period that ended at the end of the 19th century: The Little Ice Age. However, an accurate observation of the landscape of the highest peaks and adjacent valleys of the Iberian Peninsula reveals a past shaped by the successive passage of glaciers with hundreds of meters of ice, similar to what happens today in the Alps or Patagonia. Iberian glaciation has resulted in ice expansion through valleys that are now used by the road network and where important populations settle; in addition, large accumulations of sediments deposited by those glaciers are still unstable today and can trigger risks for mountain populations. Iberia, Land of Glaciers presents the impact of the glaciers in the landscape of mountains following a more educational perspective with examples of 21 Iberian massifs written by specialists from each of the areas. Assesses present-day Iberian Peninsula landscape trends by understanding the past behavior of glaciers Includes the latest findings of all the major Iberian mountains in a single book Includes quality, color figures to enhance understanding of glacier formations Provides a more educational and pedagogical perspective on glacial processes to reach an audience beyond academia

Download or read book Understanding Earth s Deep Past written by National Research Council and published by National Academies Press. This book was released on 2011-08-02 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Deglaciation written by Marcella Boone and published by Nova Science Publishers. This book was released on 2017 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global climate during the Quaternary has been deeply influenced by glacial-interglacial oscillations. Since the onset of glaciations, the Earth has experienced alternations between warm and stable climatic periods - coinciding with interglacials, and cold and highly variable climatic intervals - coinciding with glacials. In a suborbital timescale, climate oscillations were maximal during glacial onsets and, very especially, during deglaciations. Previous deglaciation events were associated with diverse changes in earth's atmospheric, physical and biotic environments. Chapter One contains a brief outline of a case study conducted in western Canada to constrain the Late Pleistocene retreat of the Laurentide Ice Sheet from the region. Chapter Two reports on the influence of deglaciations in the mid-latitude European climate. Chapter Three aims to highlight the influence of global and regional paleoceanographic changes on the deglaciation of the marine based Barents ice sheet since the last glacial maximum (LGM) until the onset of marine environment in the Holocene.

Download or read book Understanding the Last Glacial and Deglacial Ocean Circulation Using an Isotope enabled Ocean Model written by Sifan Gu and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean circulation during the last deglaciation can help to improve the understanding of the mechanisms underlying the ocean circulation. However, previous model-data comparisons suffer from indirect comparison because both reconstruction and climate model have uncertainties. To meet this challenge, my PhD work contributes to the isotope enabled Community Earth System Model (iCESM) project by developing a Neodymium (Nd) model and a Protactinium (231Pa) and Thorium (230Th) in the ocean model of CESM. With the isotope enabled ocean model (iPOP2), I investigated two scientific questions: (1) Deglacial AAIW in the Atlantic. AAIW plays important roles in the global climate system and the global ocean nutrient and carbon cycles. However, neodymium isotopic composition ([epsilon]Nd) reconstructions from different locations from the tropical Atlantic, have led to a debate on the relationship between northward penetration of AAIW into the tropical Atlantic and AMOC variability during the last deglaciation. Our results suggest a coherent response of AAIW and AMOC: when AMOC weakens, the northward penetration and transport of AAIW decreases while its depth and thickness increase. Moreover, the inconsistency among different tropical Atlantic [epsilon]Nd reconstructions is reconciled by considering their corresponding core locations and depths, which were influenced by different water masses in the past. (2) Using 18Oc to reconstruct AMOC. 18Oc gradient can be used to reconstruct density gradient, therefore the AMOC strength. 18Oc from the Florida Straits has been used to reconstruct AMOC evolution during the last deglaciation but the strength of Florida current can also be influenced by surface wind stress. Our model simulation suggests that in the western boundary, the Florida current strength is dominated by AMOC through the last deglaciation, instead of surface wind. However, in the South Atlantic, the basin-wide 18Oc contrast is decoupled from density contrast through the deglaciation in the upper ocean because of the deglacial density contrast change is dominated by salinity, which is caused by the deglacial change of AAIW. Our model suggests that 18Oc contrast across the western boundary is a good indicator for AMOC strength and 18Oc contrast across the whole basin only works for the North Atlantic.
