Sea Change
Sea Change
Bi-weekly
Hosted by Carlyle Calhoun

The award-winning podcast from WWNO/WRKF that dives deep into the environmental issues facing coastal communities on the Gulf Coast and beyond. Sea Change will bring you stories that illuminate, inspire, and sometimes enrage, but above all, remind us why we must work together to solve the issues facing our warming world. The podcast will help document our changing coasts with accountability journalism that’s too often missing from today’s media while sharing captivating stories from the people dealing with the most significant and complex problems of our time.

Hosted by Carlyle Calhoun, the show is based out of New Orleans, Louisiana which — perhaps more than any other place — embodies the existential threat of climate change. But like the city known as the Big Easy — Sea Change will also showcase joy, and resiliency — and tell powerful stories of people making a difference.

Also broadcast on 89.9 FM at noon during Louisiana Considered every other Friday.

Sea Change is distributed by PRX and is a part of the NPR Podcast Network.

Made possible with major support provided by the Gulf Research Program of the National Academy of Sciences, Engineering, and Medicine and The Water Collaborative. WWNO’s Coastal Desk is supported by the Walton Family Foundation, the Greater New Orleans Foundation, and the Meraux Foundation.

    Returning to the Carbon Coast
    Two years ago, we investigated the Liquified Natural Gas export build out on the Gulf Coast.

Today, host Carlyle Calhoun returns to LNG with Gulf States Newsroom reporter Drew Hawkins. They talk about how people in Southwest Louisiana are still being impacted by this build out, how LNG exports are affecting your electricity bills and what the war in Iran means for this industry.

    Can We Save Millions of Migrating Birds?
    We’re in the beginning of spring bird migration here on the Gulf Coast, which means warblers, vireos, orioles, and thrushes coming through as they make their way up North. Around 2 billion birds make landfall along our coast from March to May after crossing the Gulf of Mexico. But even after the high-stakes crossing of open water, their next leg of the journey is no less perilous.

  • August Walker stands amongst thousands of oyster shells at the Coalition to Restore Coastal Louisiana's restoration headquarters in Violet, LA.
