Elevated Carbon Dioxide

Atmospheric carbon dioxide rose from 316 ppm to 385 ppm over the fifty years from 1958 to 2008. The authors argue that this trend, if it continues, will shape long-term climate and, in turn, the amount farmers can harvest.

The book reports findings from field experiments on sorghum, winter wheat and rangeland vegetation grown under elevated CO2. The work was carried out over seven years at the Evapotranspiration Laboratory at Kansas State University, and the text sets out the specific results from those trials, with a focus on how plants and soil handle water under these conditions.
