    Food, Climate, and Carbon Dioxide presents the most comprehensive and up-to-date discussion on the effects of the rising level of atmospheric carbon dioxide on crop production and plant growth. The emphasis is global. It examines crops of economic value, with special attention to the food crops that stand between people and starvation.
    The author has brought together his knowledge and 50 years of experience dealing with global food production problems, coupled with and a background of his own premier research on the positive effects of elevated levels of atmospheric carbon dioxide on plant growth and crop productivity. Topics addressed include the climate as a resource in food production and climatic impacts and direct effects from rising levels of atmospheric carbon dioxide on crops. The book provides global and regional projections of a CO2 -induced climate change and food production. Food security is discussed and future possibilities for research are presented. Suitable as a text and invaluable as a reference, it presents the latest developments drawn from a wide scientific community and uses language and terminology appropriate for a diverse audience.

    Biography

    Wittwer\, Sylvan H.

    "I consider this book a 'must' reading for all persons working with 'Global Change' or 'greenhouse warming' issues. It is also an excellent summary for the non-technical reader wanting to better understand the State of the art science and the potential of interactions for many complex biological responses resulting from increasing atmosphere levels of greenhouse gases, particularly for food production. Wittwer's 'Food, Climate, and Carbon Dioxide' highlights the importance of climate and weather as a natural resource in global agricultural production. It outlines the complex interactions between climate and weather and biological systems globally and nationally. The role of climate and weather variability and extremes, usually ignored by the 'greenhouse warming' community, is correctly identified as being of greater importance to world food production, as it has been in the past and during the present time and will be in the future. The variability and extremes are the keys to future food supplies, regardless of whether the potential for global warming is achieved as projected by the limited capabilities of current General Circulation models (GCMs).
