2 2013 Spring 2015 Winter We are the University of California, and there is no reason that UC can't lead the world in this quest, as it has in so many others. - UC President Janet Napolitano We recognize the urgent need to act now and avoid irreversible costs to our global community s economic prosperity and public health. - UCSB Chancellor Henry T. Yang
