Antonio Turriel The Great Simplification

Show Summary

On this episode, physicist Antonio Turiel joins me for a wide-ranging discussion from oceans and climate to energy and culture. Oceans are one of the most important factors regulating the Earth’s climate, and yet they receive relatively little attention from the climate community. There are numerous critical risk factors to unpack regarding just the oceans alone – and still so much that we don’t know. This conversation also delves into the complexity of an economic system requiring continuous growth itself embedded in an Earth system that is already hitting its limits. What are the boundaries of our energy systems and what options do we have – and not have – for the future? Is the root of the critical issue we’re facing – not a technical problem – but a cultural problem?

About Antonio Turiel

Antonio Turiel Martínez is a scientist and activist with a degree in Physics and Mathematics and a PhD in Theoretical Physics from the Autonomous University of Madrid. He works as a senior scientist at the Institute of Marine Sciences of the CSIC specializing in remote sensing, turbulence, sea surface salinity, water cycle, sea surface temperature, sea surface currents, and chlorophyll concentration. He has written more than 80 scientific articles, but he is better known as an online activist and editor of The Oil Crash blog, where he addresses sensitive issues about the depletion of conventional fossil fuel resources, such as the peak of oil and its possible

In French, we have a motto that says that a simple drawing is often better than a long explanation. Jean-Marc Jancovici Carbone 4 President

That’s very understandable because with left atmosphere thinking, one of the problems is that you see everything as a series of problems that must have solutions. Iain McGilchrist Neuroscientist and Philosopher

We can’t have hundreds and hundreds of real relationships that are healthy because that requires time and effort and full attention and awareness of being in real relationship and conversation with the other human. Nate Hagens Director of ISEOF

This is the crux of the whole problem. Individual parts of nature are more valuable than the biocomplexity of nature. Thomas Crowther Founder Restor

The Forgotten Skills of Dying and Grieving WellWith Stephen JenkinsonThe Great SimplificationEp 190 | Stephen Jenkinson

In Western culture, topics surrounding death and dying are often considered taboo and are generally avoided in everyday conversations. But this reluctance to fully acknowledge and integrate death as a natural part of the human experience has rendered us less able to cope with the end of life and less prepared to show up for ourselves and the people around us as we inevitably navigate loss. But what if a more skillful engagement with death and grief could actually offer us a more mindful approach to living?

The Silent CollapseWith Oliver MilmanThe Great SimplificationEp 189 | Oliver Milman

Insects, bugs, creepy-crawlies – these small animals are often considered a nuisance (or worse) by humanity, bringing up an ongoing desire to kill or mitigate these “pests” that plague our backyards, homes, and gardens. But we’re beginning to see that, despite our cultural misconceptions, insects are actually at the foundation of our biosphere, food supply, and nearly every life process on Earth. This makes recent reports of rapidly declining insect populations all the more troubling – but can we recognize the vital importance of insects and reverse the harm we’ve done before it’s too late?

Nothing Can Stop This TrainWith Lyn AldenThe Great SimplificationEp 188 | Lyn Alden

Money, debt, and finance shape the lives of everyone globally, including through the policies and actions of national central banks – yet even those who are well-versed in these subjects often miss the full scope of these intricate relationships. For the average person, headlines about mounting government debt and surging interest rates often feel like a confusing and concerning trend. What can we learn from historical cycles, global energy dynamics, and the differing fiscal strategies of nations about the trajectory of the world economy?
