Inconvenient Hydrology?

Volume 6 Number 1 January/February 2007

How will climate change impact water resources? That’s the million-dollar question for water managers in the Southwest. As with any prediction about the future, we depend on past and present data, our understanding about how systems work, and models to forecast the range of likely future conditions. Measured and tree-ring-reconstructed streamflow data and ice cores tell us about climate-induced changes in the timing of runoff and the range of climate variability over centuries. Ecosystem investigations help us understand how plants respond to changes in atmospheric carbon dioxide and how such changes might affect land-use cover and, in turn, the hydrologic system. As for the models: what are they telling us, and how much confidence can we place in them? Can or should water managers respond to their predictions? Read on…
