Book Description
Towards the Balance and Management of the Carbon Budget of the Biosphere The current state of misunderstanding of the global C cycle and our failure to resolve an issue that has been debated for 100 years (Jones and Henderson-Sellers, 1990) speaks loudly about the limitations of modem science when faced with the complexity of the biosphere. Efforts to understand and balance the global C budget have gone through several phases. First was a holistic view of the C budget as part of efforts to understand the geochemistry of the Earth (e. g. , Clarke, 1908). Next, came a period of data collection and sythesis which focused on the diversity of sectors of the biosphere. This phase culminated in the early 1970's with the realization that humans were greatly impacting the global C cycle as measured at the Mauna Loa Observatory (Keeling et al. , 1973). New syntheses of the global C budget emerged at this time (Woodwell and Pacan, 1973; Bolin et al. , 1979). The next phase was one of controversy and intense focus on particular sectors of the biosphere. The controversy rested on discrepancies about the role of the terrestrial biota in the global C cycle and the failure to account for sufficient C sinks to absorb all the C emitted by land-use change in the tropics (Woodwell et al. , 1978, 1983; Houghton et al. , 1983).

Book Description
Jose Maria Figueres Olsen Former President Republic of Costa Rica The heated debate about global climate change continues. Some say it is the gravest calamity our species has ever encountered. Others deny its existence altogether. As with most caseS of human decision making, the truth is most likely somewhere in the middle. The challenge of this particular set of decisions is the overwhelming sense of uncertainty. Science cannot fully attribute the climatic catastrophes occurring before our eyes to increasing levels of greenhouse gas concentrations. Neither can Science prove that extreme events and warming trends are unrelated to human behavior. Economic models, sophisticated as they are, cannot agree on the costs of reducing carbon dioxide (C~) emissions in industrialized countries. International negotiations are thus mired in the morass of scientific and economic uncertainty. The are only two elements of certainty in the whole debate. The frrst is the need for precaution. The potential impacts are such, that the risk of inaction is unaffordable to the human race. Under the current state of knowledge, mankind must take cautious but unequivocal steps to reverse current patterns.

Book Description
NASA's Earth Science Division (ESD) conducts a wide range of satellite and suborbital missions to observe Earth's land surface and interior, biosphere, atmosphere, cryosphere, and oceans as part of a program to improve understanding of Earth as an integrated system. Earth observations provide the foundation for critical scientific advances and environmental data products derived from these observations are used in resource management and for an extraordinary range of societal applications including weather forecasts, climate projections, sea level change, water management, disease early warning, agricultural production, and the response to natural disasters. As the complexity of societal infrastructure and its vulnerability to environmental disruption increases, the demands for deeper scientific insights and more actionable information continue to rise. To serve these demands, NASA's ESD is challenged with optimizing the partitioning of its finite resources among measurements intended for exploring new science frontiers, carefully characterizing long-term changes in the Earth system, and supporting ongoing societal applications. This challenge is most acute in the decisions the Division makes between supporting measurement continuity of data streams that are critical components of Earth science research programs and the development of new measurement capabilities. This report seeks to establish a more quantitative understanding of the need for measurement continuity and the consequences of measurement gaps. Continuity of NASA's Earth's Observations presents a framework to assist NASA's ESD in their determinations of when a measurement or dataset should be collected for durations longer than the typical lifetimes of single satellite missions.

Book Description
This book describes guidelines prepared by the U.S. Country Studies Program for the evaluation of options to mitigate greenhouse gas emissions. The U.S. Country Studies Program developed these guidelines in collaboration with Lawrence Berkeley National Laboratory to provide developing countries and countries with economies in transition with reference materials for national mitigation assessments. Over 50 countries participating in the program have used the guidelines, which have been refined to reflect their comments. The guidelines delineate a step-wise methodology for evaluating greenhouse gas mitigation options for the energy and non-energy sectors and describe the applications of common analytical tools. The U.S. Country Studies Program uses these guidelines in conjunction with intensive training workshops and follow up technical assistance during the lifetime of each country's study. The program uses similar reference materials to assist counties with their greenhouse gas emission inventories and evaluations of climate change vulnerability and adaptive responses. These guidelines serve three purposes: to assist countries in making decisions about the scope and methodology for mitigation assessments; to provide countries with guidance and step-by-step instructions on each element of a mitigation assessment; and to help countries determine which analytical tools are best suited to their needs and describe procedures for applying these tools. This book describes the application of the most common and readily available methods and analytical tools. Countries are encouraged, where appropriate, to use their own methods.

Book Description
Since the 1992 Earth Summit, there have been increased efforts on an international scale to address global climate change. Reducing the increased levels of CO2 and other "greenhouse gases," which are believed to be contributing to this climatic change, will require major effort on the part of the world's governments. This means that the environmental, economic, social, and political consequences of climate change must be understood, and that strategies to mitigate climate change must also address these issues. The workshop detailed in this book concentrated on how economic principles and analysis could contribute to the planning of forestry projects aimed at affecting terrestrial carbon balances. More than 30 international scientists came together for one week near Stockholm, Sweden and divided into working groups charged with addressing a specific issue and preparing a paper within this time frame. This book contains the majority of papers presented at this meeting, and includes both the working group papers and the individually presented papers.

Book Description
Reports on recent research designed to help increase the productivity of scarce tropical farmland without damaging the environment by gaining a better understanding of the chemical, biological, and ecological aspects of relationships between the critical element nitrogen in plants and soils. Describes the use of isotopically- labeled nitrogen in experimentation, the impact of the tropical environment on nitrogen transformation in the soil, annual fluctuations of native available soil nitrogen, the interaction of major fertilizers with different soils, the role of micro-flora in nitrogen availability, the behavior of applied nitrogen in wet and submerged soils, and advances in nitrogen-fixing by Rhizobium- legume symbiosis. All but 10 of the 42 papers are reprinted from Fertilizer Research vol. 42 nos. 1-3 (1995). No index. Annotation copyrighted by Book News, Inc., Portland, OR
