  • Levke Caesar: "Oceanic Slowdown: Decoding the AMOC"

    Levke Caesar: "Oceanic Slowdown: Decoding the AMOC"
    May 22 2024

    (Conversation recorded on April 23rd, 2024)

    Show Summary:

    On this episode, Nate is joined by climate physicist Levke Caesar for a comprehensive overview of the Atlantic Meridional Overturning Circulation (AMOC) and its connections to broader planetary systems. Amid a complex and heavily interconnected climate system, the AMOC is a powerful force for regulating temperature between the Northern and Southern Hemispheres along the Atlantic Ocean - yet it’s estimated to have slowed down by about 15% over the last few decades. What are the possible domino effects of this slowing oceanic powerhouse at a regional and global scale? How well do we understand what drives the AMOC, its cyclical patterns, and connections with other currents? More importantly, how does the AMOC interact with other biospheric mechanisms that have shaped our stable, life-supporting planetary home?

    About Levke Caesar:

    Levke Caesar is a climate physicist at the Potsdam Institute for Climate Impact Research, mainly known for her studies on the Atlantic Meridional Overturning Circulation (AMOC) and its pivotal role in the climate system. Her research primarily focuses on the past, present, and future evolution of the AMOC and its intricate interactions within the North Atlantic region. Caesar's seminal work on the historical evolution of the AMOC has been featured in prestigious journals such as Nature and Nature Geoscience, garnering hundreds of citations. Since October 2023, she has assumed the role of scientific lead for the newly launched Planetary Boundary Science Initiative (PBScience) at PIK.

  • Chris Keefer: "Empowering the Future: from Nuclear to Podcasting"

    Chris Keefer: "Empowering the Future: from Nuclear to Podcasting"
    May 15 2024
    On this episode, Nate is joined by ER doctor, nuclear power advocate, and podcast host Chris Keefer for a broad ranging conversation including the basics of nuclear energy, how he engages with opposing opinions, and hypotheticals for a future medical system. Coming from a broad background, Chris understands what it means to have a human to human conversation and put together the pieces of our systemic puzzle in a clear and compelling way. What role could nuclear play for our future energy needs - and how are different countries making use of it today? How can we prioritize the health and safety of people under energetic and resource constraints? Most of all, how do we listen to others that we don’t agree with - regardless of the issue - to foster the diverse perspectives necessary to navigate the coming challenges of the human predicament? About Chris Keefer: Chris Keefer MD, CCFP-EM is a Staff Emergency Physician at St Joseph's Health Centre and a Lecturer for the Department of Family and Community Medicine at the University of Toronto. He is also an avid advocate for expanding nuclear power as the President of Canadians for Nuclear Energy and Director of Doctors for Nuclear Energy. Additionally, he is the host of the Decouple Podcast exploring the most pressing questions in energy, climate, environment, politics, and philosophy.
