    This is now one of my new favorite/go-to podcasts. It’s informative, well researched and produced, and also many of the episodes give me hope for the future of the climate. Thank you!

  • Typical pop science slop

    I am so, so tired of this formula. Start out with an unnecessarily dramatic and fundamentally inaccurate premise (we never talk about carbon unless it's to say carbon does something bad!), tell the audience what to think, trot out some "evidence," cherry pick what an expert says, play carefully selected man on the street interviews that supposedly support the premise (Dutch people are too confident about their ability to handle climate change!). Y'all must really think we're stupid, huh? That w... more

  • Lovely Listen

    Really lovely listen with great stories and insight. As a coastal person, it’s nice hearing about similar issues on other coasts and becoming more informed about the different, yet largely similar, environmental changes affecting creatures and populations inhabiting the surrounding areas. Thank you Sea Change!

  • So well done

    After hearing the fertilizer episode I had to leave a review. So often things are described as “complex” and yet they often are just not understood. I feel like I have a much greater understanding of the impact of what is happening. Thank you for your reporting. It’s valuable. Keep it up.!!

Talking Points

Recent interactions between the hosts and their guests.

From Foe to Friend: The Dutch Rethink Their War Against the Sea
Q: What is the core threat to the Dutch relationship with water as climate change progresses?
The risk is that the once-dominant engineering approach may need to yield to living with water, with more flexible, adaptive solutions as sea levels rise and weather events intensify.
It's All Elementary: Part 3 – Carbon
Q: You write about the beginning of the steam engine and industrial revolution, and how this was really a truly pivotal moment in human history that is still playing out. Take us back to that big turning point and why it's so important.
Humans were powered by carbon and, with the steam engine, could substitute labor with energy from fossil fuels, dramatically expanding growth and transforming societies, while also introducing environmental and social tradeoffs.
Losing Paradise
Q: What happened with House Bill 391 at the Louisiana Capitol?
The bill aimed to clarify public access to navigable waters but was defeated after strong opposition from landowners and oil companies, leaving the status quo and ambiguity intact.
Losing Paradise
Q: Why is public access to navigable waters such a contentious issue in Louisiana?
Because ownership of land that becomes water is disputed: landowners claim private rights over submerged land and minerals, while the state asserts public ownership of navigable waters and their beds, creating a legal and political battleground that is reinforced by economic interests in oil and gas.
Catching the Codfather
Q: Can you tell me about how you did ultimately get arrested?
The narrative explains how Rafael's business practices, including falsified documents and a cash-heavy operation, drew the attention of multiple federal agencies. Undercover agents posed as buyers, gathering evidence while Rafael explained his methods, which ultimately led to charges and his arrest as investigators pieced together the full extent of the operation.
