    The Lawn Con: Manufactured Conformity

    The Lawn Con: Manufactured Conformity

    In this episode, Ralph and Luc unpack how Americans got so obsessed with maintaining square green carpets on their front yards. We dive into the history to trace back the origins and dissemination of this artificial aesthetic. We also look into solutions, ranging from bans on gas leaf blowers to cash schemes to encourage people to quit their lawn.
    We read a poem about the lunacy of leaf blowers, and highlight ways in which manicured suburban imported lawn grass is a synecdoche for colonialism.

    How Diplomacy Closed The Ozone Hole

    How Diplomacy Closed The Ozone Hole

    In this episode, Ralph and Luc spotlight an environmental success story: the Montreal Protocol's role in healing the ozone layer. We draw comparisons to the pitfalls of the IPCC's COP process and try to derive a diplomatic blueprint for climate policy. 
    We look into the science of how ozone and chlorine works in the stratosphere, the history of the activist scientists (Sherwood Roland and Mario Molina) who first sounded the alarm about CFC's destruction of the ozone layer, and the work of technocrats in devising their replacement. We also examine the geopolitical dynamics that were foundational to this planetary victory.

    • We also sample clips from this 2021 interview with Susan Solomon (the atmospheric chemist who demonstrated CFC’s impact on ozone) and Stephen Andersen (leader of the Montreal Protocol and co-chair of its Technology and Economic Assessment Panel), by the Future of Life Institute, in which they share their roles in the closing of zone hole.https://www.youtube.com/watch?v=7hwh-uDo-6A

    Talking Climate with Conservatives

    Talking Climate with Conservatives

    In this episode, Ralph and Luc chat with Michael Jefferies, Regional Conservative Outreach Coordinator for the Citizens' Climate Lobby. Together, we get out of our filter bubbles and find some common ground.
    We discuss Michael's faith-based journey on climate issues, bipartisan proposals on issues ranging from a carbon tax ("Carbon Fees and Dividends") and import tariffs, along with strategies to communicate about the environment to conservatives.
    We also listen to excerpts from former Senator Bob Inglis talking about his experience as a pro-climate Republican.
    We hear a political advertisement recorded by Newt Gingrich and Nancy Pelosi together on a couch back in 2008.
    We read excerpts of:• Dorothy Sayers' "Why Work?" speech from 1942 and• Pope Francis' "Laudato si'" encyclical from 2015.

    Gaslighting (Big Oil Knew)

    Gaslighting (Big Oil Knew)

    In this episode, Ralph and Luc spotlight what the oil companies knew about CO2’s impact on the climate, and how they lied to you to sustain their fossilized business model – even if it risks drilling us into oblivion… This argument will soon be heard in court as part of a series of lawsuits against Big Oil.
    We start by looking into the history of scholarship on this issue, dating back to the 19th Century.We highlight the record of what the oil companies such as Exxon and the American Petroleum Institute were saying behind closed doors – and contrast this with their contemporaneous public statements.
    We draw upon scholarship uncovered by Naomi Oreskes and the #ExxonKnew movement.

    Rainforest Restitution

    Rainforest Restitution

    In this episode, Ralph and Luc venture into the thorny discussions of what to do about the rainforest’s impact on the globe. In the aftermath of Lula's conference in Belem, Brazil, in August 2023, we spotlight some good news: great strides are being made against deforestation, and South American leaders are keen to protect the Amazonian rainforest. We also unpack criticisms and highlight pragmatic perspectives from Colombia and Ecuador, such as debt for nature swaps.
    Sources:• We sample a quote from climate scientist Stephen Schneider from this 1981 British TV documentary by Thames Television called “Warming Warning”. You can see the clip in context at: https://www.youtube.com/watch?v=9zHAbYOXjzk/

    Save the Earth? (ft. George Carlin)

    Save the Earth? (ft. George Carlin)

    In this episode, Ralph and Luc listen to a stand-up routine by comedian George Carlin about environmentalists. We engage with Carlin’s pontifications and his ingenious framing by providing context from a scientific perspective. We also gesture at disarming some of his cynicism while steering clear of fully explaining away what made his take comedic in the first place.
    This episode contains 4 brief excerpts from George Carlin's "Jammin' in New York" special.

Indispensable and different

This podcast is a treasure. They take a deep dive into subjects in a way that most of us don’t have the time to do. And then their presentation is engaging and, most importantly, actionable. The Gaslighting episode alone should be listened to by everyone on the planet. Thank you for such a great resource!

Impressive

As an educator, this podcast is a must listen to. It's great to share with students in K 12 and higher. Ralph and Luke do a great job at informing listeners of critical issues in our lives, and it motivated me to learn more and to take action.

The Thorough Thoreau ,

Upbeat, idealistic and informative!

What a breath of fresh air this podcast is. Ralph and Luc have an infectiously positive energy. I came away from their latest episode really feeling that I had a grip on South America and what needs to happen.
