Millions of people are currently feeling the effects of Hurricanes Maria, Irma and Jose. And millions more are vulnerable, according to UC Santa Cruz professor Gary Griggs. He says that approximately 61 million people live in Gulf and South Atlantic coastal communities that are susceptible to hurricanes. Griggs joins us to discuss the recent spate of storms, sea level rise and other threats to coastal communities and environments that he explores in his new book, "Coasts in Crisis."
