International leaders continue negotiations Monday at the climate talks in Paris, and some Louisianans are there to advocate for their communities. One of those is principle chief of the United Houma Nation, Thomas Dardar.

The Houma have long inhabited south Louisiana but are not federally recognized as a Native American tribe, partly because the government requires that tribes have a central base, but the Houma population is very spread out.

Tulane researchers say sea levels are rising faster than expected. Gulf Coast communities from the Florida Panhandle to East Texas are most at risk.
