In October 2012, Superstorm Sandy cut a path of devastation across the Caribbean and the East Coast of the United States, killing hundreds and causing tens of billions of dollars in damage. One year after Sandy's deadly strike, NOVA investigates the critical question raised by this historic storm: What can we do to prepare ourselves for the next Sandy? Much of the devastation was due to flooding from an extreme storm surge, and with sea levels on the rise, flooding will become more frequent. 

What is the role of global warming in driving these rising seas, and what will it take to make cities like New York more resilient? NOVA travels around the world to see how other low-lying urban areas are combining extraordinary engineering with natural landscape restoration and a smarter, more flexible power grid to prepare for an uncertain future. NOVA also interviews climate scientists who are racing to understand how a warming world will affect extreme - but unpredictable - weather phenomena like hurricanes and tornadoes.
