Scientists say they’ve linked climate change to torrential rain and flooding along the Gulf Coast, such as the deadly flooding in Louisiana in August. The flooding last month killed 13 people and displaced tens of thousands from their homes. Scientists from the National Oceanic and Atmospheric Administration and others say global warming makes it at least 40 percent more likely the U.S. Gulf Coast will be inundated by historic downpours. August was the wettest month in Baton Rouge in 174 years, when record keeping began.
