Rivers in a greenhouse world.

Rivers in a greenhouse world

As carbon dioxide and other gases push up the Earth's surface temperature, how will the warming affect the world's major rivers? James R. Miller of Rutgers University in New Brunswick, N.J., and his colleagues have used an atmospheric general circulation model to study this question. The model predicts how changes in precipitation, evaporation, soil absorption and other factors will alter the world's 30 largest rivers. In general, the model shows rivers in the tropics might carry less water while those closer to the poles end up with more runoff, they report. For now, though, Miller says he questions the results because the model does not do a good job of predicting the current runoff values for many rivers.
