Why a paper about relocating coastal communities hit a nerve

Back in May, a paper published in Nature Sustainability reignited a decades-old debate about coastal Louisiana: Should people leave? Climate researchers wrote that due to rising sea levels, coastal Louisiana has crossed the point of no return and that governments should be making plans now for places like New Orleans to relocate.

Jessica Dandridge-Smith, who runs The Water Collaborative in New Orleans, speaks with Flora about why this paper sparked such a strong reaction, and how she thinks about the possibility of relocation. Then, we chat with climate scientist A.R. Siders about how we can plan for the future while taking care of our communities in the present.
