In the midst of a drought in 2008, biologists discovered dead Coho and steelhead trout in a tributary of the Russian River. When the dust settled, the focus turned to how winegrowers and other water users could reduce their impact. The event provided the parties involved—winegrowers, conservationists, and the water agency—an opportunity to find common ground in the realm of science.

It’s only when we “zoom out” to the planet-wide scale that trends in surface temperature are obvious: despite a few, rare areas experiencing cooling, the vast majority of places across the globe are warming.

A few storms found their way to the drought-stricken California coast late this winter, but they barely made a dent in the state's huge water deficits. As the North Pacific winter storm season recedes, there is little likelihood for substantial drought recovery.

Federal law may protect the river habitat in the name of endangered fish, but on land, grapevines are king. This article is the first in a two-part series about how scientists are helping find compromise amid local tensions over water supplies.
