This month's World Wildlife Fund newsletter (the blandly titled "Focus") included a brief report ("Tucson Helps Lead the Way") on the work of Leslie Ethen, director of conservation and sustainability for the city of Tucson.

She is currently leading a team to assess how vulnerable Tucson is to increased drought, water scarcity and extreme heat." Go ahead, rub it in, Barbara Kingsolver, (High Tide in Tucson).
