Saving the World From Bad Ideas

Bad Idea #53 "History shows nuclear war will never happen.” with David Holloway

In this episode of Saving the World from Bad Ideas, Mark Lynas speaks with Stanford historian David Holloway about one of the most dangerous assumptions of the nuclear age: history shows nuclear war will never happen. Drawing on Holloway’s new book Nuclear Weapons and International History, they trace the development of the bomb from the Manhattan Project to the thermonuclear age, the Cuban Missile Crisis, launch-on-warning doctrines, arms control, and the unraveling of the post-Cold War nuclear order. The conversation makes clear that the fact nuclear war has not happened yet is no guarantee it never will. Instead, it is a story of repeated near misses, fragile restraint, and a continuing risk that humanity has learned to treat as background noise. 🧠 Topics Discussed ☢️ Why David Holloway wanted to write an international history of nuclear weapons 💥 The difference between atomic bombs and hydrogen bombs 🔥 Why thermonuclear weapons transformed the scale of human destructiveness 🧊 How the Cold War became a confrontation shaped by catastrophic nuclear risk 🚨 How close the Cuban Missile Crisis came to becoming a nuclear war 🛳️ The Soviet submarine incident on Black Saturday and the role of sheer luck ☎️ Why the hotline and early arms control efforts emerged after Cuba 🕊️ How scientists helped launch the anti-nuclear movement 🎯 How deterrence, mutual assured destruction, and launch-on-warning doctrines evolved ⚠️ Why false alarms and misread signals remain one of the greatest nuclear dangers 🤖 How artificial intelligence and new technologies may make nuclear risk worse 🛰️ Why missile defense systems like Star Wars and the proposed Golden Dome are so controversial 📉 How the arms control system built during the Cold War has eroded 🌍 Why a world with fewer nuclear weapons is still a world in grave danger ❓ Whether humanity can find an alternative to living indefinitely with nuclear arsenals 👩‍🏫 Guest Bio David Holloway is Emeritus Professor of History at Stanford University and one of the world’s leading historians of nuclear weapons and the Cold War. His work has focused on the Soviet Union, international security, nuclear strategy, and the political history of the atomic age. His new book, Nuclear Weapons and International History, offers a sweeping account of how nuclear weapons shaped global politics from 1945 onward. 📚 Recommended Reading & Resources * Nuclear Weapons and International History by David Holloway * Six Minutes to Winter by Mark Lynas * Research and historical accounts of the Cuban Missile Crisis * Writing on the Russell-Einstein Manifesto and the Pugwash movement * Histories of nuclear deterrence, arms control, and the thermonuclear arms race 💬 Quote Highlights 💬 “I think we’re entering a new and very dangerous period, partly linked to changes in the world order.” - David Holloway 💬 “The H-bomb is a big step forward in terms of sheer destructiveness.” - David Holloway 💬 “It was a war they didn’t want that they came close to having.” - David Holloway 💬 “We’re entering a new and very dangerous period.” -David Holloway 💬 “We can live with nuclear weapons...

Bad Idea #52 "Attenborough’s films ignore human impacts” with Colin Butfield

“Attenborough’s films ignore human impacts.” In this episode of Saving the World from Bad Ideas, Mark Lynas speaks with filmmaker and environmental storyteller Colin Butfield, co-founder of Open Planet Studios and a long-time collaborator of David Attenborough. They discuss how Attenborough’s work has evolved from classic nature spectacle toward a much more explicit confrontation with ecological destruction, restoration, and humanity’s role in shaping the living world. Through the making of Ocean with David Attenborough, they explore the shocking reality of bottom trawling and Antarctic krill fishing, the changing grammar of nature documentaries in the Anthropocene, and why stories of damage now have to sit alongside stories of recovery. It is a rich conversation about storytelling, responsibility, and the power of film to show that human impacts can no longer be ignored. 🧠 Topics Discussed: * 🎥 What it is like working with David Attenborough over nearly two decades * 🗣️ How Attenborough delivers those iconic pieces to camera * 🌍 How nature documentaries shifted from pristine spectacle to ecological reality * 🌊 Why Ocean with David Attenborough was made as an urgent film about human impacts * 🐟 How bottom trawling devastates marine ecosystems on an industrial scale * 🛑 Why bottom trawling is still allowed in many marine protected areas * 🐋 How Antarctic krill fishing competes directly with whales and destabilises the Southern Ocean food web * 🧾 Why “sustainable” seafood labels often deserve much more scrutiny * 📚 How films can remain true to documentary storytelling while still driving real-world campaigns * 🎬 Why Open Planet gives footage away for education and advocacy * 🌱 What ecological recovery can look like when people choose restoration and protection * 🤝 Why humans are not inherently destructive and can become a force for good * 🐻 What it takes to film extraordinary wildlife and wild places around the world * 🚀 Why “we can always go and live on Mars” is its own terrible environmental fantasy 👩‍🏫 Guest Bio:Colin Butfield is co-founder and director of Open Planet Studios. As a filmmaker, writer and environmental storyteller, he has worked on major productions including A Life on Our Planet, Breaking Boundaries, Our Planet, and Ocean with David Attenborough. He has also co-written Ocean with David Attenborough and works at the intersection of documentary storytelling, conservation, and public engagement. 📚 Recommended Reading & Resources * Ocean by David Attenborough and Colin Butfield * Ocean with David Attenborough * Open Planet * Campaigns and research on bottom trawling in marine protected areas * Work on marine protection, krill fisheries, and ocean restoration * Sea Shepherd footage and reporting on the Southern Ocean krill fishery 💬 Quote Highlights💬 “This is what we’ve chosen to do as a society or chosen to allow.”Colin Butfield 💬 “I can absolutely sympathize with a community casting nets, even bottom trawling though I hope we can get away from that to feed their families, feed their communities, and earn a living. That’s a million miles away from going all the way down to Antarctica, hauling up krill for pet food and supplements.”Colin Butfield 💬 “You just got to a point where it felt very strange... not to mention humanity or talk about the changes that are happening in them.”Colin Butfield 💬 “It was unavoidable.

Bad Idea #51 "plenty of krill in the ocean" with Claire Christian

Antarctica is the least disturbed continent on Earth — and for some of the world's most powerful fishing nations, that's not a reason to protect it. It's a reason to go there next. Claire Christian, Executive Director of the Antarctic and Southern Ocean Coalition, joins Mark Lynas to make the case that the bad idea is to look at the antarctica regian as a pantry, plenty of krill in the ocean, right? That idea still persists, debated in closed rooms in Hobart, and dressed up in sustainability labels. Christian traces the arc from industrial whaling and penguin-boiling in the early 1900s — one of the first modern wildlife protection campaigns — through the Cold War-era Antarctic Treaty miracle, to today's battleground: krill. The Southern Ocean krill fishery is small by global standards but growing fast, dominated by Norwegian vessels, eyed hungrily by China, and certified "sustainable" by the Marine Stewardship Council despite trawlers threading directly through the feeding grounds of recovering whale populations. What emerges is a picture of governance under pressure. CAMLR — the commission governing the Southern Ocean fishery — operates by consensus, meaning Russia and China can block marine protected area proposals indefinitely while simultaneously pushing to expand catch limits. Two MPAs exist (the Ross Sea and the South Orkneys). More are on the table, extensively researched, scientifically rigorous — and stalled. The Antarctic Peninsula, one of the fastest-warming places on the planet, still has no formal protection. Christian also unpacks the krill industry's favourite talking point: that the catch is less than 1% of total biomass. The problem isn't total biomass — it's where the fishing happens. Krill concentrate in a few small areas. So do the penguins, seals and recovering whale populations that depend on them. The wildlife can't go elsewhere. The ships could. So far, CAMLR hasn't required it. The meta bad idea, in Christian's own words: that the burden of proof should rest on nature rather than on us. 🧠 Topics Discussed: 🐧 The original sin: industrial whaling, seal hunting, and boiling penguins for oil — and the early 1900s campaign that became one of the first modern wildlife protection efforts 🐳 The recovery miracle: humpback whales possibly back to 80% of pre-whaling numbers — and the extraordinary discovery that more whales actually means more krill 🦐 Krill 101: why almost everything in the Southern Ocean either eats krill or eats something that eats krill — and why a 50-armed predatory starfish is just as important as a penguin 📜 The Antarctic Treaty system: how Cold War geopolitics accidentally produced one of the most forward-looking conservation treaties in history 🎣 How krill fishing started: the Soviet Union, the El Dorado effect, and the logic of "the whales are gone, so there must be more krill for us" 🏷️ The MSC certification problem: how a "sustainable" label on suppresses pressure on CAMLR to actually improve management 🌡️ Climate change as wild card: sea ice loss, shifting krill distributions, and why uncertainty is an argument for more precaution, not less 🗳️ CAMLR's consensus trap: how Russia and China demand more science before protecting — but not before fishing ⚖️ The burden of proof argument: who should have to prove harm — industry or nature? 👤 Guest Bio: Claire Christian is the Executive Director of ASOC, the Antarctic and Southern Ocean Coalition — a global network of NGOs dedicated to the protection of Antarctica and the Southern Ocean. She has been an observer at CAMLR negotiations and has written extensively on marine conservation governance, MSC certification, and Southern Ocean fisheries management. 📚 Recommended Reading & Resources: * ASOC — Antarctic and Southern Ocean Coalition [https://www.asoc.org] * CAMLR — Commission for the Conservation of Antarctic Marine Living Resources * The Antarctic Treaty Secretariat [https://www.ats.aq] * High Seas Treaty (BBNJ Agreement) — IUCN overview [https://www.iucn.org/our-work/topic/ocean/high-seas-treaty]

Bad Idea #50 "clean energy is too expensive for Africa" with Daan Walter

Clean energy won't work in the global south... right? At a moment when the fossil fueled economy is cracking under geopolitical pressure, Daan Walter of EMBER brings the data that reframes everything: clean energy is moving ahead, in developing countries — it's already winning. Walter unpacks EMBER's latest electricity review findings: for the first time, wind and solar absorbed nearly all global electricity demand growth in 2024, causing fossil fuel generation to actually fall. And unlike the economic shocks of 2020 or 2013, this is structural. The episode covers the ElectroTech revolution's three core drivers — none of which are explicitly about climate. Walter explains why emerging economies, far from lagging, are leapfrogging the West: over 50% of CVF nations now out-solar the United States. The Strait of Hormuz crisis is accelerating everything. Pakistan's bottom-up solar revolution — millions buying off Alibaba, DIY-installing, disconnecting from failing utilities — is the preview of what comes next everywhere. Nuclear gets a candid assessment too, the question is how it can play nice with solar dominating the grid. Walter closes with a refreshingly honest admission: we don't know yet how to solve the last 5-10% of the grid cleanly — but that's fine. The right move is to sprint the 90% we can solve and invest in R&D for the rest, rather than let perfect be the enemy of transformational. 🧠 Topics Discussed: ⚡ ElectroTech defined: why wind, solar, batteries, EVs, and heat pumps all cluster around electricity as their magnetic center 📉 Bad idea autopsied: "clean energy is too expensive for developing countries" — true five years ago, dangerously wrong today 🌍 CVF nations leapfrogging: 50%+ of the world's most climate-vulnerable countries out-solar the US 💸 Capex parity moment: upfront costs of EVs and solar panels now matching fossil alternatives — the game-changer for capital-constrained economies 🌞 Solar as baseload: 80-90% uptime solar + battery achievable at ~$100-120/MWh; UAE Masdar project hit 99.5% uptime below $70/MWh 🛢️ Hormuz crisis as accelerant: biggest energy shock since the 1970s, turbocharging electrotech exports from China globally 👨‍💼 Guest Bio: Daan Walter is a Principal at EMBER, where he leads global energy strategy research. His CV spans Rocky Mountain Institute (batteries, efficiency, mineral demand), McKinsey, and two graduate degrees from the University of Cambridge — one in nuclear energy, one in theoretical physics. He's one of the sharpest analysts tracking the real-time pace of the ElectroTech revolution. 💬 Quote Highlights: "The answer is not 'you're wrong.' The answer is: you were right five years ago." — Daan Walter "The poorest countries in the world and the poorest families within countries are adopting ElectroTech because it's the cheapest option now, not the most expensive." — Daan Walter "We identify three key drivers of the ElectroTech revolution across the world. None of those three are explicitly climate." — Daan Walter "Every country in the world has a small Saudi Arabia worth of energy falling from the skies on them every year. All they need to do is put a panel up and capture it." — Daan Walter "By 2040, we might be in a very highly electrified, very low-carbon economy — in the same way that by 2040, we might be in an economy that largely runs on AI white-collar work." — Daan Walter 🌐 About WePlanet:WePlanet is a global citizen and science movement challenging bad ideas and championing evidence-based solutions for climate, nature, and human progress.

Bad Idea #49 "We can stop worrying about the climate" with Zeke Hausfather

“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.
