sea level rise

Louisiana’s soil is sinking much faster than previously thought -- that’s the conclusion of a new report out this week from Tulane University.

This week on the Coastal News Roundup, WWNO’s Travis Lux speaks with Tulane wetlands geologist Molly Keogh, who authored the report, about what that means for sea level rise predictions in Louisiana.

Environmental issues were big news in 2018 -  locally, nationally, and globally. World leaders from 195 countries gathered in Poland to discuss how to reduce global greenhouse gas emissions. A major federal climate report said the U.S. is already feeling the effects of climate change - in the shape of deadly wildfires, devastating hurricanes, and record temperatures.

The chemicals used to help clean up the BP oil spill, known as dispersants, have been already been accused of damaging the health of humans and sea life. Now, a new study says they were ineffective at doing what they were meant to do: clean up the oil.

This week on the Coastal News Roundup, WWNO's Travis Lux speak with Nola.com/The Times-Picayune's Tristan Baurick about the study. Plus, a look at the black rail -- a coastal bird threatened by sea level rise.

The new Louis Armstrong airport is set to open next year. The $1 billion facility is big, sleek - and only four feet above sea level.

Reporter Jennifer Larino has been covering the new airport for Nola.com/The Times Picayune, and she talked with WWNO’s Tegan Wendland about how prepared it is for the threats of climate change.

A new study shows Louisiana’s land loss has slowed down a little bit. But that’s still not necessarily good news.

 

It’s almost become a tired refrain here in Louisiana -- the state loses an average of about a football field of land every hour. Now it takes about 100 minutes, roughly an hour and a half for that much land to wash into the Gulf of Mexico.

Last week President Trump pulled the U.S out of the Paris Climate Agreement -- or Paris Climate Accord. When it was ratified in 2015 it was a big deal -- almost every country in the world met in Paris to agree on a way to fight climate change.

 

But Trump says the deal isn’t good for business. Pulling out could have implications for Louisiana. WWNO's Travis Lux talked with Dr. Bob Thomas, professor of environmental communication at Loyola University, about what it will mean.

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.
