…[T]he places in the West experiencing huge population growth are likely to face the most chronic water shortages. How do we address that?
You’re going to have water problems resulting from climate change whether you’re in a water-scarce area or one that’s going to get more water. It doesn’t matter. The consequences of climate change—whether drought, flooding, or water contamination caused by rising ocean levels—will force us to adapt to a different way of managing water resources. There’s no silver bullet. Are we accommodating people that come to southern
…Should the cost of water in
Oh, absolutely. But it’s how you step into it. You can’t go from where you are now all the way there overnight. It becomes ineffective. You have to stair-step into it. You also have to provide enough of a financial incentive to get people to make the conversions. You’re not out to punish people; you want to remind them of the value of water, and there’s a point at which water pricing is not flexible. That first 5,000 gallons—maybe even 8,000—is inelastic. People are going to use it regardless. They’re going to take a shower. So it is a very delicate balance that you have to strike.
…When you read about water, all roads eventually lead back to climate change. Are you optimistic about the future, or do you feel like we’re in some sort of race with calamity?
I think we’re at a crossroads. We have an opportunity to start turning things around. Everyone worries about some kind of economic Armageddon that’s going to happen as a consequence of climate change. We need to define very carefully how our journey into sustainability is going to go. There is a lot of low-hanging fruit we haven’t taken advantage of. But we’ve got to come to grips with the fact that it’s happening, be willing to look it square in the face, start talking about what changes we need to make, and quit pretending it doesn’t exist.
