Answer» Answer: Effects of Increasing Carbon Dioxide Levels and Climate Change on Plant Growth, Evapotranspiration, and Water Resources Leon Hartwell ALLEN, Jr. U.S. Department of Agriculture Gainesville, Florida The atmospheric carbon dioxide CONCENTRATION has risen from about 270 parts per million (PPM) before 1700 to about 355 ppm today. Climate changes, including a mean global surface temperature rise of between 2.8 and 5.2°C, have been predicted by five independent general circulation models (GCMs) for a doubling of the carbon dioxide concentration. The objectives of this paper are to examine plant responses to rising carbon dioxide levels and climatic changes and to interpret the CONSEQUENCES of these changes on crop water use and water resources for the UNITED States.
