Available in PDF, EPUB and Kindle. Book excerpt: Since 1958, CO2 concentrations at Mauna Loa Observatory have been obtained using a nondispersive, dual detector, infrared gas analyzer. Air samples are obtained from air intakes at the top of four 7m towers and one 27m tower. Those involved in the monitoring project have attempted to improving sampling techniques, reduce possible contamination sources, and adjust data to represent uncontaminated, true conditions throughout the twenty-eight year sampling period. The gas analyzer is calibrated by standardized CO2-in-nitrogen reference gases twice daily. Flask samples are taken twice a month for comparison to the data recorded using the infrared gas analyzer. Data are scrutinized daily for possible contamination and archived on magnetic tape for further scrutiny and adjustment. Daily, monthly, and annual averages are computed for the Mauna Loa data after deletion of contaminated samples and readjustment of the data. These averages have shown a steady rise in annual average concentration from 316 parts per million by volume (ppmv) in 1959 to 346 ppmv in 1986.

This book was released on 2012-12-06 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest decline became a matter of public and scientific concern in France in 1983 when conifers in the Vosges mountains were found to exhibit unusual crown deterioration. An impassioned controversy on a supposedly large scale forest health problem was then in full swing in Central Europe. A co-ordinated research programme entitled DEFORPA ("Deperissement des For~ts et Pollution AtmospMrique") was launched in 1984. This programme ran from 1984 to 1991 and a number of projects are still in progress. The Programme was sponsored by three French ministries (Enviroument, Agriculture and Forestry, Research and Technologyl), several state agencies, various regional authorities and the Commission of the European Communities (DO xn and DG VI). Initially, emphasis was solely laid on the understanding of forest decline in the mountainous areas - because damage was most obvious there - in relation to natural and man-made factors. Air pollution was given high but not overwhelming priority. Thus, the DEFORPA Programme was not in its essence a nation-wide assessment of air pollution effects, unlike a number of national acidification research programmes in Europe and North America. During. the programme, however, the areas of concern expanded. In particular, research into water acidification in the Vosges mountains was developed in parallel with the DEFORPA Programme, and possible eutrophication of the ground flora in northeastern France became the subject of new research.

Download or read book Engineering Response to Global Climate Change written by Robert G. Watts and published by CRC Press. This book was released on 1997-07-30 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book goes beyond the analysis offered by typical works on this subject to propose real solutions to problems caused by changes in the earth's climate. From new ways to cut energy consumption and reduce carbon dioxide emissions to discussions of the possibilities of sea walls and climate-altering technologies, Engineering Response to Global Climate Change presents new conceptual tools and suggests research necessary for correcting and alleviating problems caused by global warming. Engineers are just now being asked to consider the problems of climate change and the possible technological responses. This complete reference covers the whole range of potential impacts of climate change and their engineering solutions. Of special interest is the chapter on geoengineering, which suggests how engineers may someday be able to intervene in planetary processes to reduce the effects of global warming. Edited by a regional director of the National Institute for Global Environmental Change and offering the collective expertise of a team of expert authors, each renowned in his or her field, this book offers thorough coverage of this important topic from an engineering and technology perspective.
Download or read book Biogeochemistry written by William H Schlesinger and published by Academic Press. This book was released on 2012-12-02 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biochemistry: An Analysis of Global Change provides information pertinent to the chemistry of the surface of the Earth. This book presents the basics about the effect of life on the chemistry of the Earth. Organized into two parts encompassing 14 chapters, this book begins with an overview of the connection between the elements that are significant to life. This text then describes how computer models are employed to help understand elemental cycling and ecosystem function. Other chapters consider how satellite technology is beneficial in understanding global biochemistry. This book discusses as well the essential role theta the Earth Observing System (EOS) will play in investigations of global ecology. The final chapter deals with the human effect on global biochemical cycles, with focus on controlling human population growth to maintain life and quality of life on Earth. This book is a valuable resource for college-level and graduate students who are interested in global change.
Download or read book Tropical Forests in Transition written by J. Goldammer and published by Birkhäuser. This book was released on 2013-03-08 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: In evolutionary time scales natural disturbances have affected the vegetation on Earth. During the Quaternary the forest biomes of the tropics were subjected to manifold disturbances. Climate changes and climate oscillations were associated with changing precipitation and drought regimes, flooding, siltation, landslides, etc. The prehistorical forest was also influenced by the effects of large wildlife populations. Large-scale catastrophies in the forest biomes were mainly caused by abiotic environmental alterations, the small-scale disturbances were and still are related to both biotic and abiotic processes. Both the large-and the small-scale disturbances have played a significant role in shaping distribution, dynamics, structure and composition of the paleoforest. After the expansion of hominids and early humans, and later, by modern humans, the anthropogenic influences on the tropical forest began to overlap natural disturbances. Today's anthropogenic impacts on the tropical forests differ qualitatively and quanitatively from the natural disturbances. The speed of tropical deforestation and savannization is dramatically increasing. The physical and chemical impacts of forest conversion and biomass burning add to other anthropogenic influences on the atmosphere and climate. The expected anthropogenic climate change will also have considerable impacts on the tropical flora and fauna. The book on "Tropical Forests in Transition" synthesizes information on changing environmental conditions and human impacts on the tropical forest by looking back to the paleoecology, analyzing the impact of modern human populations and modeling the future of the tropical forest in a changing environment. The aim of the book is to strengthen multidisciplinary thinking in disturbance ecology.

Download or read book The Global Carbon Cycle written by Martin Heimann and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the outcome of a NAill Advanced Study Institute on the contemporary glo bal carbon cycle, held in n Ciocco, Italy, September 8-20, 1991. The motivation for this ASI originated from recent controversial findings regarding the relative roles of the ocean and the land biota in the current global balance of atmospheric carbon dioxide. Consequently, the pur pose of this institute was to review, among leading experts in the field, the multitude of known constraints on the present day global carbon cycle as identified by the fields of meteorology, physical and biological oceanography, geology and terrestrial biosphere sciences. At the same time the form of an Advanced Study Institute was chosen, thus providing the opportunity to convey the information in tutorial form across disciplines and to young researchers entering the field. The first three sections of this book contain the lectures held in II Ciocco. The first sec tion reviews the atmospheric, large-scale global constraints on the present day carbon cycle including the emissions of carbon dioxide from fossil fuel use and it provides a brief look into the past. The second section discusses the role of the terrestrial biosphere and the third the role of the ocean in the contemporary global carbon cycle.
