The Great Simplification with Nate Hagens

Twenty-five years ago, a landmark paper warned that the world’s coral reefs could vanish by 2050. Now, halfway to that projected date (and amid ever more frequent coral bleaching events), that grim prediction feels increasingly close to reality. What is the current state of Earth’s coral reefs, and what would happen to our planetary home without them? 
 
In this episode, Nate is joined by Ove Hoegh-Guldberg, the marine biologist who made this landmark prediction, for an update on the health of coral reefs and the primary ecological stressors driving their decline. Drawing on decades of research, he explains the mechanisms of coral bleaching, the critical biodiversity hotspots that reefs create, and the implications for human populations that depend on these ecosystems. Ove also touches on the emotional impact of witnessing the loss of reefs for the scientists who have dedicated their lives to studying them.
 
How are human actions increasingly putting pressure on the very ecosystems that support more than one billion people? What would happen to the broader health of the oceans if reefs were to disappear entirely? And most of all, what changes can both individuals and institutions make today to support the health of these vital ecosystems – and in-turn, the well-being of the entire Earth?

About Ove Hoegh-Guldberg:
 
Ove Hoegh-Guldberg is Professor of Marine Studies at the University of Queensland in Brisbane, Australia, as well as the Deputy Director of the Centre for Excellence in Coral Reef Studies. Over the past 10 years, he was also the Founding Director of the Global Change Institute. In addition to this work, Ove conceived and led the scientific XL-Catlin Seaview Survey which has surveyed over 1000 km of coral reefs across 25 countries and captured and analysed over 1 million survey images of coral reefs. 
 
Ove’s research focuses on the impacts of global change on marine ecosystems, and he is one of the most cited authors on climate change. He has also been a dedicated communicator of the threat posed by ocean warming and acidification to marine ecosystems, being one of the first scientists to identify the serious threat posed by climate change for coral reefs in a landmark paper published in 1999, which predicted the loss of coral reefs by 2050.

Will Coral Reefs Be Gone by 2050? How Bleaching, Acidification, and Ocean Heating are Killing Coral Reefs with Ove Hoegh-Guldberg

For many people in the modern world, electricity powers everything we do. Yet we take for granted how power flows in the background, seemingly always accessible to us just by flipping a switch. In fact, most of us are completely unaware of what it takes to generate and transmit the power we so deeply rely on, let alone the policy decisions shaping our electrical grids – or how they might affect reliable access to power. How do today’s electrical grids actually work, and do they align with our long-term goals for human and planetary well-being?
 
In this episode, Nate is joined by Meredith Angwin for an in-depth overview of the U.S. electrical grid system, its history, and the need for accountability in energy governance. Meredith discusses the infrastructure of the grid, the complexities of grid management, and the implications of shifting to market-based systems. Additionally, she emphasizes the critical importance of resource adequacy and reliability – and the barriers to that in our current policy landscape. 
 
How has the increased use of renewables and natural gas affected the broader dynamics of the grid? If the electrical grid were to fail, who is responsible for the problem, and who should fix it? Ultimately, what variables do we need to consider as we attempt to provide dependable electricity for everyone without jeopardizing the stability of the Earth? 
 
 
 
About Meredith Angwin:
 
Meredith Angwin studies and takes part in grid over-sight and governance. For four years, she served on the Coordinating Committee for the Consumer Liaison Group associated with ISO-NE, her local grid operator. She also teaches courses and workshops on the electric grid, and wrote a book titled, Shorting the Grid: The Hidden Fragility of our Electric Grid, analyzing the electrical grid from a physical science and policy perspective.
 
As a working chemist, Meredith Angwin headed projects that lowered pollution and increased reliability on the electric grid. Her work included pollution control for nitrogen oxides in gas-fired combustion turbines, and corrosion control in geothermal and nuclear systems. Further, she is an inventor on several patents and was one of the first women to be a project manager at the Electric Power Research Institute where she led projects in renewable and nuclear energy.

In this week’s Frankly, Nate returns from New York City Climate Week with fresh reflections on the disconnect between our economic narratives and biophysical realities. Using his background in finance, Nate observes that while the prioritization of financial abstractions and claims continue to accelerate, with gold and silver prices reaching record-setting highs, the ledger is being balanced with parallel declines in our planetary health and social resilience. This tradeoff is harder and harder to ignore as newly crossed planetary boundaries continue alerting us to the fact that we are operating outside of our Earth’s ability to maintain biospheric stability.
 
Nate also gives an update on Peak Oil, drawing on the International Energy Agency’s recent report regarding the implications of oil and gas field decline rates. He emphasizes that the question at hand is not if these energetic supply constraints will affect the trajectory of human systems – rather, the question is when it will come into effect, and how we will respond as a human species.
 
Given the increasing number of reports on declining oil forecasts, how much longer can our society remain energy-blind? Where might our priorities shift if we truly understood the biophysical limits shaping our future? Lastly, if we were to zoom out towards a wider boundary lens, what types of societal responses become possible that could steer us towards better human and planetary futures?

Peak Oil, Ponzi Pyramids, and Planetary Boundaries

The overarching definition of success today often looks like the accumulation of stuff – money, cars, property, clothing – anything that signals wealth. This means that success is also synonymous with overshoot, extraction, and consumption – none of which lead to healthy outcomes for the planet or the global good. But what might be possible if we were to redefine success to prioritize collective well-being instead of personal gain?
 
In today’s episode, Nate sits down with Dutch historian and author Rutger Bregman to discuss the concept of moral ambition, which he defines as the desire to be one of the best, measured by different standards of success: not by big payouts or fancy honorifics, but by the ability to tackle the world’s biggest problems. Bregman highlights the importance of entrepreneurs in driving social change and the necessity of cultural shifts to foster a more altruistic society, as well as the challenges faced in pursuing these ideals.
 
What possibilities might arise if we combined the idealism of an activist with the ambition of an entrepreneur? How can we apply the principles of entrepreneurship to better address global challenges? And how could a radical redefinition of success motivate the world’s top talent to make major contributions to our most pressing issues, leaving a legacy that actually makes a difference?

Moral Ambition: Redefining Success for the Global Good with Rutger Bregman

In this week’s Frankly, Nate reflects on intraspecies predation (ours) and the impact psychopathic actors have on the mean and median of human behavior – in the past all the way up to our modern society. Human evolution was shaped by both cooperative, pro-social behavior and a competitive, predatory approach for survival – resulting in a balanced distribution for most of humanity’s existence. 
 
But, as agriculture, surplus, and other factors propelled more hierarchical social structure, aggregate human behavior and culture has slowly shifted over time to express more psychopathic traits. This thread of behavior continues to run through our modern society, where a relatively small (but disproportionately powerful) segment of the human population can pull societal behavior towards anti-social and individualistic values – even if the majority of people still inherently operate from a place of reciprocity.
 
Why might our modern society provide a more fruitful breeding ground for psychopathy than past societies did? What do chickens and eggs have to do with psychopathy and the economic superorganism? And ultimately, what strategies could we begin to think about in order to shift mean and median human behavior back towards a more cooperative, prosocial middle?

The Influence of Psychopaths: Why Humanity Is Better Than We Think

For many people today, the idea of societal collapse is unimaginable. Yet history shows that well-established civilizations have fallen again and again – often for similar reasons. In fact, the same forces that build empires can also culminate in their downfall. How can understanding these historical patterns help us prepare for similar existential risks we may already be facing today? 
 
In this episode, Nate is joined by existential risk researcher Luke Kemp to explore the intricate history of societal collapse – connecting patterns of dominance hierarchies, resource control, and inequality to create societies which he calls Goliaths. Together, they delve into the deep history of what egalitarian humans were like before complex civilizations emerged, and the changes in climate and agriculture that created the conditions for hierarchical societies. Luke explains how these very same factors have culminated in the rise and fall of Goliaths, and how these have led to today’s global challenges such as nuclear warfare and even AI-fueled surveillance states. 
 
Can knowing our past help us avoid repeating it? Are we in collapse now, and was this civilizational trajectory inevitable? How does the study of civilizational collapse help us grasp the best and worst of humanity – and can we use that knowledge to lean into the better sides of ourselves and put ourselves on a different, more resilient path?

The Past and Future of Societal Collapse: Why Civilizations Fall and What We Can Learn From It with Luke Kemp

Psychopathy is often portrayed as a rare and distant phenomenon – something confined to movie villains or prison cells. Yet when psychopathy is combined with narcissism and Machiavellianism to form what psychologists call the Dark Triad, its impact becomes far more immediate. Individuals with these traits can wield disproportionate influence over our culture, institutions, and daily lives. What goes on inside their minds, and how do they shape the world around us?
 
In this episode, Nate is joined by Dr. Reid Meloy and Dr. Nancy McWilliams to explore the inner workings of the Dark Triad personality traits and their manifestation in modern culture. Together, they trace the evolutionary roots of these traits, examine the predatory ways Dark Triad individuals engage with others, and consider the profound implications for leadership, power, and governance. Ultimately, they emphasize the importance of truth and community when navigating the complexities of human behavior.
 
Why are Dark Triad individuals more likely to occupy positions of power? How do current cultural norms and expectations actually incentivize Dark Triad tendencies, including in governance? Most importantly, how can reorienting towards collective communication and cooperation help create guardrails against these ‘darker angels’ of humanity?

Dark Triad Personality Traits: How Psychopathy, Narcissism, and Machiavellianism Impact Our Cultures & Social Systems | RR 19

In this week’s Frankly, in a continuation of his ‘This Week's Learnings’ series, Nate updates viewers on things he learned in the past week, and the implications for our sociocultural trajectory. This edition focuses on recent financial and political headlines – global gold holdings, shifting geopolitical energy deals, and new U.S. Department of Energy reports – and explains their relevance to our biophysical reality and broader geopolitical landscape. Through this exercise, Nate invites podcast viewers to use a systems lens to integrate the wide array of news we are bombarded with into the large evolving story of The Human Predicament.
 
Why does it matter that central banks now hold more gold than the U.S. treasuries? How might expanding energy collaborations between Russia and China shift the global political power of the United States and Europe? How do current economic and political incentives affect the nature of energy science, and what we consider to be ‘truth’ itself?

This Week's Learnings: Gold Holdings, Political Divides, and the DOE Climate Report | Frankly 107

To best understand this episode, please watch this ~2 minute video on the biotic pump.
 
 
 
It’s widely known that Earth’s forests provide home to countless numbers of species, act as a vast sink for carbon, and provide much of the food, materials, and clean water on which our societies rely. But emerging science shows us that forests may play another critical role: making rain. This theory, called the biotic pump theory, hypothesizes that instead of being passive recipients of rain, forests may actively create the conditions for precipitation over land – a premise that turns modern meteorology on its head.
 
In this episode, Nate is joined by physicist Anastassia Makarieva about the critical yet often overlooked role forests play in maintaining ecological balance and climate stability. Through the lens of the biotic pump theory, she highlights the importance of moisture and rainfall cycles, the dangers of ecosystem tipping points, and the escalating risks of deforestation. Anastassia argues that a paradigm shift is needed – one that redefines how humanity understands and manages forests in the fight against global heating.
 
What would climate models reveal if they fully integrated the Biotic Pump Theory? How might policies protecting against deforestation evolve if societies recognized the irreplaceable role forests play in how water moves on land? And beyond policy, how might reconnecting with our deep interdependence on forests help us rediscover a richer connection to ourselves as individuals?
 
(Conversation recorded on July 9th, 2025)

 
 
 
About Anastassia Makarieva:
 
Dr. Anastassia Makarieva is a Russian atmospheric physicist and senior researcher at the Petersburg Nuclear Physics Institute. She obtained her Ph.D. in atmospheric physics from St. Petersburg State University in 2000. Makarieva is best known for co-developing the "biotic pump" theory alongside the late Professor Victor Gorshkov. The theory posits that forests play a crucial role in driving atmospheric moisture transport, effectively influencing rainfall patterns over land. Her work emphasizes the importance of intact forests in maintaining climate stability and has challenged conventional climate models to incorporate the dynamic role of vegetation in atmospheric processes.

Why We Need Forests: Their Vital Role in Climate Dynamics, Rain, and The Biotic Pump with Anastassia Makarieva

In this week’s Frankly, Nate weighs the value of a pound of gold with other things that we derive worth from in our lives – from dollars and bitcoin to...less pecuniary markers. Although gold is simply a metal, it has long been a symbol of wealth in human cultures. Through highlighting other important, sometimes intangible forms of wealth, Nate encourages the viewer to not only examine what they place the most worth on in their own lives, but also to consider why things have worth to us as humans living in a complex, modern system.
 
What contributes to the real wealth of your life – and can it be measured and held, or is it something more intangible? And finally, how might our definitions of wealth change if we were -as individuals and as a culture - to fully appreciate the miracle that is human life and connection with one another and the natural world?
