MIAMI BEACH, FL - SEPTEMBER 29: People walk through a flooded street that was caused by the combination of the lunar orbit which caused seasonal high tides and what many believe is the rising sea levels due to climate change on September 29, 2015 in Miami Beach, Florida. The City of Miami Beach is in the middle of a five-year, $400 million storm water pump program and other projects that city officials hope will keep the ocean waters from inundating the city as the oceans rise even more in the future.
