Beskrivelse

“We can stop worrying about the climate.” In this episode of Saving the World from Bad Ideas, Mark Lynas speaks with climate scientist Zeke Hausfather about a dangerously complacent idea: we can stop worrying about the climate. As recent years have broken temperature records and warming appears to be accelerating, they explore why that conclusion is badly mistaken. The conversation unpacks the hidden role of aerosols in masking warming, what recent spikes in temperature do and do not mean, whether net zero really stops further warming, and how seriously we should take tipping points, geoengineering, and carbon removal. The result is a clear-eyed discussion that pushes back against both panic and complacency, and argues for staying focused on the scale and complexity of the climate challenge. 🧠 Topics Discussed 🌡️ Why the rate of global warming appears to be increasing ☁️ How aerosols have masked part of the warming caused by greenhouse gases 🚢 Why shipping pollution controls became part of the climate conversation 🧮 What happens if sulfur dioxide emissions fall even further ♻️ Why reaching net zero means temperatures likely stabilise rather than keep rising 📈 What explains the exceptional warmth of 2023 and 2024 🌍 Whether the world has actually passed 1.5°C yet 🔥 Why climate complacency is just as misleading as climate fatalism 🧊 How to think clearly about tipping points, from permafrost to ice sheets 🌊 What we know, and do not know, about AMOC slowdown and Arctic feedbacks 🛠️ Why solar radiation management remains controversial, risky, and unresolved 💨 Why geoengineering cannot replace emissions cuts 🪨 Which carbon removal pathways seem most promising today 💸 Why carbon removal is likely to matter, even if it stays expensive ⚡ Why solving climate change will require many tools rather than one master fix 👩‍🏫 Guest Bio Zeke Hausfather is a climate scientist and climate research lead at Stripe. He writes for Carbon Brief, publishes the The Climate Brink Substack, and has served as a lead author for the IPCC. His work focuses on observed warming, climate model performance, carbon removal, and the intersection of climate science and policy. 📚 Recommended Reading & Resources The Climate Brink by Zeke Hausfather Zeke Hausfather’s work for Carbon Brief IPCC reports on 1.5°C, mitigation, and carbon removal Frontier and Stripe’s work on carbon dioxide removal Research on aerosols, shipping emissions, and recent warming trends Research on solar radiation management and carbon removal technologies 💬 Quote Highlights 💬 “Our best estimate removing sort of natural variability is that the current rate of warming due to human activity is somewhere in the order of 0.27C.” — Zeke Hausfather 💬 “If you were to get rid of sulfur dioxide emissions completely... you would end up at about two degrees of warming rather than the 1.5 or 1.4 we’re at today.” — Zeke Hausfather 💬 “Getting to net zero emissions of all greenhouse gases and aerosols would lead to roughly flat temperatures.” — Zeke Hausfather 💬 “All of these geoengineering approaches we’re talking about... are literally that.” — Zeke Hausfather 💬 “There’s no silver bullet, but there’s silver buckshot when it comes to climate change.” — Zeke Hausfather 🌐 About WePlanet WePlanet is an international movement campaigning for science-based solutions to the climate, nature and development crises.

Bad Idea #58 “Environmentalists Are All the Same” with George Monbiot

In this season-ending episode of Saving the World from Bad Ideas, host Mark Lynas is joined by environmental journalist and author George Monbiot to explore a new framework for understanding environmentalism. George argues that what is often treated as a single movement actually contains three distinct and frequently conflicting philosophies: Green Liberationism, Green Pragmatism, and Green Social Nostalgia. The conversation traces the historical roots of each tradition, from anti-colonial activism and technocratic climate policy to rural revivalism and its relationship with fascism. Along the way, Mark and George discuss population debates, food systems, ecomodernism, the influence of religion on environmental thought, and the growing challenge of far-right infiltration into parts of the green movement. It's a wide-ranging examination of the ideas and tensions that shape environmentalism. 🧠 Topics Discussed 🌱 Why environmentalism may be better understood as three competing philosophies rather than a single movement ✊ What George calls "Green Liberationism" and how it draws on civil rights, anti-colonial struggles, feminism, and social justice movements ⚙️ What "Green Pragmatism" looks like in practice, from clean energy deployment to technocratic climate governance 🌾 What George means by "Green Social Nostalgia" and why he sees it as a powerful but problematic force within environmentalism 📜 Why George argues that rural revivalism became a foundational component of twentieth-century fascist movements 🌳 How post-war environmentalism inherited ideas from both progressive and deeply conservative traditions 🍽️ Why George believes many nostalgic visions of agriculture struggle to answer basic questions about feeding large populations 👶 How population anxiety became embedded in parts of environmental thought and why George sees it as politically unhelpful ⛪ How Christian traditions, pastoral imagery, and millenarian thinking continue to shape environmental narratives 🧘 How wellness culture, alternative health movements, and environmental politics can become vulnerable to far-right influence 🌍 What figures like RFK Jr., Vandana Shiva, and other controversial environmental voices reveal about ideological drift within green movements 🍔 How precision fermentation, microbial protein, and cultivated foods could transform debates about meat, land use, and sustainability 🤝 Why successful environmental politics requires combining technological innovation with democratic participation and social legitimacy 🚨 Why the environmental movement may be underestimating the challenge posed by far-right actors adopting green rhetoric 👤 Guest Bio George Monbiot is an environmental journalist, author, and campaigner known for his work on ecology, politics, land use, food systems, and climate change. A longtime columnist and public intellectual, he has written extensively on environmental justice, rewilding, democracy, and the social forces shaping ecological crises. 📚 Recommended Reading & Resources 📖 Feral — George Monbiot [https://www.amazon.es/Feral-Rewilding-Land-Human-Life/dp/014197558X] 📖 Regenesis — George Monbiot [https://www.amazon.es/Regenesis-Feeding-without-Devouring-Planet/dp/0141992999/ref=asc_df_0141992999?mcid=447f5f5b601b3e2a96708a8008c8217c&tag=googshopes-21&linkCode=df0&hvadid=699740312373&hvpos=&hvnetw=g&hvrand=10739503227769828885&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9181150&hvtargid=pla-1825142069477&psc=1&hvocijid=10739503227769828885-0141992999-&hvexpln=0] 📖 The Anatomy of Fascism by Robert Paxton [https://www.amazon.es/Anatomy-Fascism-Robert-Paxton/dp/0141014326/ref=asc_df_0141014326?mcid=aeb931b70fda3c38a126b3f05fb646e2&tag=googshopes-21&linkCode=df0&hvadid=699717042937&hvpos=&hvnetw=g&hvrand=12916333990235467948&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9181150&hvtargid=pla-475945273665&psc=1&hvocijid=12916333990235467948-0141014326-&hvexpln=0] 📖 Works by Wendell Berry [https://www.amazon.es/Selected-Poems-Wendell-Berry/dp/1582430373/ref=asc_df_1582430373?mcid=f863dda091a43529afb15c6d7f083813&tag=googshopes-21&linkCode=df0&hvadid=800413681198&hvpos=&hvnetw=g&hvrand=3497387002051701778&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9181150&hvtargid=pla-488426896211&psc=1&hvocijid=3497387002051701778-1582430373-&hvexpln=0] 📖 Writings and debates surrounding Paul Kingsnorth and the Dark Mountain Project 💬 Quote Highlights 💬 “You can have rural revivalism without fascism, but you can’t have fascism without rural revivalism.” — George Monbiot 💬 “Power and politics don't disappear when you push people out of the way.” — George Monbiot 💬 “You needed the technologies in order to realise the more political liberationist vision.” — George Monbiot 💬 “We’ve been far too unprepared for the takeover of aspects of our movement by the far right.” — George Monbiot 🌐 About WePlanet WePlanet is an international movement campaigning for science-based solutions to the climate, nature and development crises. 📥 Join the Conversation 💬 ⁠podcast@weplanet.org⁠ 📩 ⁠https://weplanet.org/podcast⁠ 👁️⁠ https://twitter.com/weplanetint⁠

Bad Idea #57 “Hands off Mother Earth” with Anni Pokela

In this episode of Saving the World from Bad Ideas, Mark Lynas speaks with Anni Pokela of Operaatio Arktis about why “Hands off Mother Earth” is no longer a serious response to the climate crisis. The conversation explores how humans are already deeply entangled with planetary systems, whether through emissions, land use, or atmospheric pollution, and why the real question is no longer whether we intervene, but how we do so responsibly. From Arctic tipping points and AMOC collapse risks to solar radiation management, social license, indigenous engagement, and the politics of research, this is a probing discussion about climate intervention in a world where inaction is itself a form of intervention. 🧠 Topics Discussed 🧊 Why Arctic tipping points pushed former climate activists to rethink the limits of conventional climate politics 🌍 Why the term “geoengineering” may be misleading if humans have already been reshaping the planet for centuries 🌊 Why the weakening AMOC has become a major concern in Finland and across the Nordic region ☀️ How solar radiation management, especially stratospheric aerosol injection, entered the climate debate ☁️ What marine cloud brightening is, and why it is being explored in places like Australia ⚖️ Why climate intervention has to be understood through risk comparison, not moral purity 🗳️ Why shutting down research is undemocratic, especially for countries on the front lines of climate impacts 🚨 How the “dangerous distraction” argument can end up policing climate discourse instead of opening it 🧪 Why more public, transparent, internationally shared research matters before private actors shape the field 🧭 What Scopex revealed about indigenous consent, scientific arrogance, and the need for better governance 🤝 Why Anni argues that these technologies should be approached through entanglement, responsibility, and democratic legitimacy rather than technological denial 🌐 Why the biggest risks may lie less in the particles themselves than in geopolitics, power, and unequal decision-making 📚 Why this whole field needs more input from humanities, philosophy, sociology, and justice-oriented perspectives, not just climate modeling 👩‍🏫 Guest Bio Anni Pokela is part of Operaatio Arktis, a Finnish climate strategy and communications organization founded by former Extinction Rebellion Finland activists. The group works with researchers and institutions to support responsible, ethically sustainable climate intervention research, with a particular focus on Arctic risks, tipping points, justice, and democratic governance. 📚 Recommended Reading & Resources Operaatio Arktis Research on AMOC weakening and Arctic tipping points Work on solar radiation management and marine cloud brightening Discussions around Scopex, social license, and indigenous consent Research on climate intervention governance, justice, and public legitimacy 💬 Quote Highlights 💬 “The question then ceases to be whether we should intervene or not. The question then becomes how do we do it?” Anni Pokela 💬 “How are we responsibly in that relationship and in that entanglement with the planet?” Anni Pokela 💬 “Shutting down public research around this topic... it’s madness.” Anni Pokela 💬 “It only sort of benefits the people who want to do this in the shadows.” Anni Pokela 💬 “Things. You know, when we... have the blue dot that we can save... the question then kind of ceases to be whether we should intervene or not.” Anni Pokela 🌐 About WePlanet WePlanet is an international movement campaigning for science-based solutions to the climate, nature and development crises.

Bad Idea #56 "Just leave it to the market" with Tom Crowther

In this episode of Saving the World from Bad Ideas, Mark Lynas speaks with global ecologist Tom Crowther about a seductive but dangerous assumption: just leave it to the market. While part of the conversation focuses directly on capitalism, inequality, poverty, and wealth redistribution, the discussion is much broader than economics alone. Drawing on Tom’s new book Nature’s Echo, they explore how feedback loops shape everything from the birth of stars to the spread of ideas, the dynamics of ecosystems, the structure of societies, and the possibility of ecological recovery. The central argument is that markets can generate growth, innovation, and momentum, but without balancing forces they also drive instability, degradation, and collapse. It is a wide-ranging conversation about regeneration, resilience, scientific thinking, and how human systems might better mirror the stabilising logic of the natural world. 🧠 Topics Discussed 🔁 Why feedback loops are one of the most useful ways to understand nature and society 🌌 How the same looping dynamics help explain the formation of stars, life, and ecosystems 😱 Why climate doomism can become self-fulfilling if it closes off regenerative possibilities ⚡ Why renewables and electrification may now be driven by powerful self-reinforcing momentum 📉 Why no exponential growth system lasts forever, and why overshoot matters 🌱 How regenerative feedback loops can build when livelihoods improve alongside nature 🚜 Why Tom distinguishes regenerative livelihoods from simplistic anti-industrial romanticism 🌾 How nature loss can eventually reduce agricultural yields, even in intensive systems 🥩 Why plant-based proteins and nuclear energy could radically reduce ecological pressure 💸 Why poverty is one of the strongest drivers of environmental degradation 🧾 How wealth redistribution can act as a stabilising feedback in both society and ecology 🌳 What the trillion trees controversy got wrong about restoration 🗺️ How the Restore platform helps land stewards, funders, and the public support regeneration on the ground 🧪 Why science needs both rigour and humility, especially when defining the world in fixed categories 🧠 How constructivist thinking, belief, and consensus shape the way societies understand reality 👩‍🏫 Guest Bio Dr Tom Crowther is a global ecologist working across multiple universities, with his foundation based in Switzerland. His research spans biodiversity, forests, restoration, agriculture, and the feedback loops that shape planetary systems. He is also the author of Nature’s Echo: Harnessing Ancient Feedback Loops to Heal a Changing Planet, which is now available. 📚 Recommended Reading & Resources Nature’s Echo: Harnessing Ancient Feedback Loops to Heal a Changing Planet by Tom Crowther The Restore platform Research on ecological restoration, regenerative livelihoods, and nature recovery Work on feedback loops in climate, biodiversity, and social systems Writing and debate on trillion trees, reforestation, and restoration policy 💬 Quote Highlights 💬 “For me, the bad idea is that we’re doomed to a bleak future.” Tom Crowther 💬 “There’s unbelievable potential for regenerative loops to build momentum as well.” Tom Crowther 💬 “I am trying to think like a natural system.” Tom Crowther 💬 “I think our economic system needs to perfectly mirror that.” Tom Crowther 💬 “Poverty is the biggest driver of degradation.” Tom Crowther 💬 “When they are lifted out of poverty, that is when nature thrives and they start to thrive more, which makes nature thrive more.” Tom Crowther 🌐 About WePlanet WePlanet is an international movement campaigning for science-based solutions to the climate, nature and development crises.

Bad Idea #55 "Life's only about competition" with Rowan Hooper

In this episode of Saving the World from Bad Ideas, Mark Lynas speaks with science writer Rowan Hooper about one of the deepest misconceptions in biology: that life is only about competition. Drawing on Hooper’s new book Togetherness, they explore how symbiosis and cooperation run through life at every scale, from lichens and corals to ants, orchids, the human microbiome, and even the origin of complex cells. The conversation also revisits Darwin, Malthus, ecology, overconsumption, and the ways modern society has been shaped by an overly narrow reading of evolution. It is a wide-ranging discussion about why life’s greatest successes often come not from ruthless struggle alone, but from collaboration, interdependence, and living together. 🧠 Topics Discussed 🧬 Why cooperation and symbiosis have been neglected in biology for so long 🍄 How lichens show that radically different life forms can combine into one successful organism 🪸 Why coral reefs depend on symbiosis between animals and algae 🔋 How mitochondria and chloroplasts reveal that complex cells were built through endosymbiosis 🦠 Why humans are ecosystems, not just individuals, thanks to the microbiome 🧠 How symbiotic microbes influence digestion, mood, sleep, and immunity 📚 Whether modern understandings of symbiosis challenge Darwin, or deepen him ⚔️ How Darwin strategically emphasized competition to make his theory acceptable 📈 Why Malthusian thinking shaped both Darwinism and modern ideas of scarcity 🌾 How artificial fertilizer helped humanity escape Malthus, while creating new ecological damage 🐜 How leaf-cutter ants became extraordinary farmers through fungal symbiosis 🌸 Why orchids cannot even germinate without fungal partners 🌍 How ecological stress and climate change are breaking down vital symbiotic relationships 🧪 Why technologies such as genetic engineering may help restore ecological function 🌱 What it means to live more ecologically on a crowded planet 👩‍🏫 Guest Bio Dr Rowan Hooper is a science writer and author whose work explores biology, evolution, ecology, and what science can tell us about the human place in nature. In this episode he discusses his new book, Togetherness: Symbiosis and the Hidden Story of Life’s Greatest Collaborations. The book is published on June 4 in the UK, and on August 14 in the US and Canada. 📚 Recommended Reading & Resources Togetherness: Symbiosis and the Hidden Story of Life’s Greatest Collaborations by Rowan Hooper Charles Darwin’s On the Origin of Species Work on Lynn Margulis and endosymbiosis Research on the human microbiome Writing on ecology, soil health, plant-fungal symbiosis, and coral bleaching 💬 Quote Highlights 💬 “The emphasis ever since Darwin has been on competition. And while that is correct in many ways, it’s led to a terrible neglect of cooperation and symbiosis.” Rowan Hooper 💬 “That’s done real damage to the way we live in the world.” Rowan Hooper 💬 “I am an ecosystem, mobile ecosystem.” Rowan Hooper 💬 “Darwin was actually... a very cunning plan basically. He did it deliberately in order for his book to be accepted.” Rowan Hooper 💬 “Orchids are super successful and the whole root of their success is through symbiosis.” Rowan Hooper 💬 “From the origin of life to now and then into the future.

Bad Idea #54 "Shut down the cobalt mines" with Nicholas Niarchos

In this episode of Saving the World from Bad Ideas, Mark Lynas speaks with journalist and author Nicholas Niarchos about the dirty, dangerous, and politically fraught supply chains behind lithium-ion batteries. Using cobalt mining in the Democratic Republic of Congo as a central case study, they explore how a technology essential to electrification and decarbonisation became tied to child labour, unsafe artisanal mines, corruption, colonial legacies, and weak global accountability. The conversation pushes back against a simplistic response, namely shutting down cobalt mining altogether. Niarchos argues that cobalt is a highly effective battery material and that the real problem is not the mineral itself, but the governance failures and moral outsourcing that allow abuse to persist across global supply chains. 🧠 Topics Discussed 🔋 Why lithium-ion batteries became central to the clean energy transition ⚙️ Which minerals go into modern batteries, including cobalt, copper, lithium, nickel, graphite, and phosphates 🏭 How Exxon helped pioneer lithium-ion battery research before abandoning it 🚗 Why lithium-ion batteries made modern electric vehicles viable ⛏️ Why cobalt from the DRC became so important to battery chemistry 👷 The realities of artisanal mining, including child labour, mine collapses, and extreme precarity 📱 How major brands such as Apple are tied to these supply chains, even when they claim high standards ⚖️ Why industrial mines and artisanal mines differ, but both still raise serious questions ♻️ Why recycling alone does not solve the underlying justice problem 🧪 Whether sodium-ion and other new battery chemistries will reduce dependence on cobalt 🌍 Why the goal should be fixing the supply chain, not abandoning battery technology or Congo itself 👩‍🏫 Guest Bio Nicholas Niarchos is a journalist and author whose work focuses on conflict, extraction, inequality, and global supply chains. In this conversation he discusses his book on the hidden human and political costs behind lithium-ion batteries and the minerals that power the energy transition, especially in the Democratic Republic of Congo. 📚 Recommended Reading & Resources * The Elements of Power by Nicholas Niarchos * Reporting on cobalt mining and battery supply chains in the Democratic Republic of Congo * Research on artisanal and industrial cobalt mining * Work on battery chemistry, electrification, and critical minerals * Analysis of colonial extraction, governance, and resource politics in Central Africa 💬 Quote Highlights * 💬 “The bad idea is the battery supply chain itself, which arose from a series of decisions that didn’t seem to be taken particularly consciously, but seem to be driven by avarice, essentially.” - Nicholas Niarchos * 💬 “I have been to mines that sit directly in Apple’s supply chain and watched as people without shoes go into these mines.” - Nicholas Niarchos * 💬 “The iPhone is the great success story for Apple. Don’t forget it. This success was built on the backs of these kinds of labor conditions. - Nicholas Niarchos * 💬 “If we start recycling all our material, which we’re admittedly a very, very long way off from, what gets left in Congo? - Nicholas Niarchos * 💬 “There’s no need to go to sodium. There’s no need to try and figure out new technologies... because we have the technology. The technology is the lithium ion battery.” - Nicholas Niarchos * 💬 “The bad idea is the supply chain, not the use of cobalt in batteries.” - Mark Lynas 🌐 About WePlanet WePlanet is an international movement campaigning for science-based solutions to the climate, nature and development crises.
