      Presentation by Chris Field,

      Ecological Impacts of Climate Change

      Climate-change responses are already clear [p. 10]
      --- Range shifts
      --- Signs of spring
      --- Plant growth
      --- Agricultural yields

      Trends in US agriculture [p. 9]
      --- Over the last 50 years,
      yields of US corn and
      soybeans increased 1-2 % per year
      --- But year-to-year
      increases were larger in
      cooler years and smaller
      in warmer years
      --- A warming of 1 degree F
      decreased yields by 9 %

      Climate Experts Urge Immediate Action to Offset Impact of Global Warming
      Excerpt: Welcome presentation
      by Don Kennedy
      CEO AAAS
      "Governments and consumers in the United States and worldwide should
      take immediate steps to reduce the threat of global warming and to
      prepare for a future in which coastal flooding, reduced crop yields
      and elevated rates of climate-related illness are all but certain,
      top U.S. scientists said Tuesday."
