Jacquie Ayala (L) and Amanda Lawrence stand in a flooded street as they and others call on the presidential candidates to talk about their plans to fight climate change on October 18, 2012 in Miami Beach, Florida. Some of the streets on Miami Beach are flooded due to unusually high tides that the protesters felt are due to rising seas, which are connected to global warming and climate change. Published reports indicate that Florida ranks as the most vulnerable state to sea-level rise, with some 2.4 million people, 1.3 million homes and 107 cities at risk from a four-foot rise in sea levels.
