Increasing atmospheric carbon dioxide concentrations are expected1 to cause major changes in the world's climate over the next 50–100 yr. The impact of such changes on water resources, through changing precipitation and evaporation, will, however, be complicated by the direct effects of increasing CO2 on vegetation. In controlled environment experiments, higher CO2 levels cause the stomata of plants to close down, decreasing their rate of transpiration and increasing their water use efficiency2… 
Hydrological effects of changes in levels of atmospheric carbon dioxide
The potential influence of increasing levels of atmospheric carbon dioxide (CO2 ) on water resources includes changes in evapotranspiration that result from control of stomatal resistance by CO2 and
Responses of arid and semiarid watersheds to increasing carbon dioxide and climate change as shown by simulation studies
The atmospheric concentration of carbon dioxide is expected to double in the next century causing increased temperatures and decreasing precipitation in some regions of the U.S. The increase in CO2

The global hydrological cycle is expected to change over the next century as a consequence of human perturbations to the Earth System. Human activities are modifying the composition of the
Large-Scale Water Manipulations
Researchers predict that increasing levels of greenhouse gases in the atmosphere will cause a 1 to 3.5°C increase in average global temperatures and alter regional levels of precipitation (Kattenberg
Sensitivity of water resources in the Delaware River basin to climate variability and change
Because of the "greenhouse effect", projected increases in atmospheric carbon dioxide levels might cause global warming, which in turn could result in changes in precipitation patterns and
Projected increase in continental runoff due to plant responses to increasing carbon dioxide
The physiological effect of doubled carbon dioxide concentrations on plant transpiration increases simulated global mean runoff by 6 per cent relative to pre-industrial levels; an increase that is comparable to that simulated in response to radiatively forced climate change.
Climate change, whether natural or due to human action, will have an impact on many aspects ofour environment. The nature ofstreamflow changes will depend on the magnitude and direction of the
Hydrologic effects of climate change in the Delaware River Basin, by Gregory J. McCabe, Jr. and Mark A. Ayers
Water resource scientists, planners, and managers need to know what hydrology changes to expect due to CO{sub 2}-induced climate warming. McCabe and Ayer's study is a useful first-cut approximation
Regional hydrologic and carbon balance responses of forests resulting from potential climate change
The projected response of coniferous forests to a climatic change scenario of doubled atmospheric CO2, air temperature of +4 °C, and +10% precipitation was studied using a computer simulation model


Rising atmospheric carbon dioxide concentrations may increase streamflow
Historically, studies of the greenhouse effect of carbon dioxide (CO2) have dealt primarily with temperature and only secondarily with precipitation. In the latest report on this topic1, however, the

Sensitivity of a global climate model to an increase of CO2 concentration in the atmosphere
This study investigates the response of a global model of the climate to the quadrupling of the CO2 concentration in the atmosphere. The model consists of (1) a general circulation model of the
