Michael Barnard: Climate solutions can be full of sh*t
Full show notes and bonus content at wickedproblems.earth.In this episode we talk about climate tech in the age of AI, state failure, and the occasional aircraft powered by poop. In this episode, Canadian climate futurist and returning champion Michael Barnard joins us for a globe-spanning conversation about why he’s still cautiously optimistic — and why, if you’re only paying attention to the U.S. or Europe, you’re probably looking the wrong way.In Conversation· Pakistan's rooftop solar revolution: how a glut of Chinese panels and uncoordinated net metering turned into 22 GW of grassroots decarbonization in a single year.· Ports, poop, and power: what district heating, sewage sludge, and whiz-powered planes tell us about what works — and what’s quietly already scaling.· China’s decarbonization surprise: Michael walks us through why China’s emissions have actually started to fall, why Western media missed it, and why most U.S. industrial policy is a “radically stupid” own-goal.· The end of American credibility: on failed trade narratives, disappearing clean energy investment, and the strategic competence of the so-called Global South.· Three technologies to watch: Geothermal heat-as-a-service, waste-based sustainable aviation fuels, and electrified ports as power utilities of the future.Timeline02:28 Optimism in the Face of Climate Challenges05:08 Pakistan's Energy Transformation14:16 Leapfrogging in the Global South21:23 China's Role in Global Emissions Reduction27:08 The Rise of the Electro State28:33 China's Dominance in Critical Minerals29:37 Globalism and Neoliberalism: A Mixed Bag30:42 The Market Economy's Failures32:13 Technology Diffusion and Industrial Policy34:48 The United States' Broken Industrial Policy43:04 Geothermal Energy Innovations46:04 Sustainable Aviation Fuel from Waste49:35 The Future of Electrified PortsFurther Reading* CarbonBrief on China's emissions drop* Jenny Chase (BNEF) on Pakistan’s rooftop solar boom* Barnard on ports and maritime decarbonisation* Sustainable Aviation Fuels from Human Waste* The Dawn of Everything by Graeber & Wengrow* Trifecta Ireland – new NGO for clean, secure, affordable energy* Kingsmill Bond (Ember) on the rise of the Electrostate v Petrostate Hosted on Acast.

How Journalism Could Survive AI (w Mic Wright)
Get bonus content at wickedproblems.earth! Mic Wright is the madman media survivor behind one of this show’s second-favourite newsletter, Conquest of the Useless . So when we heard he has a new book out in a couple of weeks we were delighted he could give us a few minutes to talk meeja matters in the age of AI and climate consequences.Breaking: How the Media Works, When it Doesn’t and Why that Matters - despite my inability to stop obsessing about whether it is missing an Oxford comma in the title - is the magnum opus of Britain’s best observer of all things media since Christopher Hitchens went from Trot to Neocon.Two years before the Brexit referendum, a year long inquiry by a UK parliamentary select committee concluded that BBC news teams consistently engaged in false balance when reporting on climate change stories. So for a senior news journalist to suggest that they weren't familiar with the concept felt like a very stark confession.Head back even further to the misty, almost unimaginable, past of 2006, and you find Rob Corddry on the Daily Show, parodying journalists who bent over backwards to establish balance where there is none:“How does one report the facts? When the facts themselves are biased from the names of our fallen soldiers to the gradual withdrawal of our allies to the growing insurgency, it's become all too clear that the facts in Iraq have an anti-Bush agenda.”Meatless speech was rightly praised for highlighting the influence of Conservative Party appointees on the BBC, but it also contained a series of confessions about missing the elephant in the room. Even as the stench of dung must have been stifling.In Conversation00:35 Introducing Mic Wright01:31 Technical Challenges and Interview Preview03:13 Mic Wright's Dramatic Reading04:16 Discussion on False Balance in Journalism13:07 The Rise of Churnalism15:14 Media Ownership and Influence19:39 Tech Enthusiasm and AI in Journalism32:14 Conclusion and Final ThoughtsGet the Books at the Wicked Problems Bookshop.org ShopWe like writers.

Cara Maesano of RMI: Can Heavy Industry Scale CDR?
Bonus content - wickedproblems.earth As we talked about with folk from Carbon Technology Research Foundation and Robert Höglund last week, Carbon Dioxide Removal (CDR) is going through some things. The Trump administration is slashing funding for Direct Air Capture (DAC) hubs, poster child CDR firm Climeworks is laying off 20% of staff and stands accused of overpromising an underdelivering on removals.But in a week when a Swiss village was wiped off the map by a collapsing glacier, and the World Meteorological Organisation predicted we’re likely facing years of staying at 1.5°C above pre-industrial levels - the existential threshold for small island states they demanded be included in the Paris Agreement - the need to find ways to take greenhouse gases out of the air (while electrifying and decarbonising) has not gone away.Cara Maesano has one of the most comprehensive views of the state of CDR technologies as the head of CDR research at RMI. Recent reports she helped craft point out pragmatic opportunities for joined-up thinking by integrating carbon removals in industry and agriculture - and even using captured carbon in building materials.In Conversation01:30 Challenges in the Direct Air Capture Sector07:54 Exploring Different Carbon Removal Technologies12:06 Industrial Carbon Removal Opportunities23:40 Industry Partnerships for Carbon Removal24:03 Economic Benefits of Carbon Removal25:41 Momentum in Climate Action27:50 Innovative Building Materials for Carbon Storage32:44 Engaging Stakeholders in Carbon Removal33:28 Highlighting Successful Carbon Removal Projects35:13 Challenges and Opportunities in Policy and Regulation37:25 The Ongoing Climate Conversation38:52 Connecting Climate Solutions Across Sectors42:20 Conclusion and Final ThoughtsFurther ReadingRMI: Seizing the Industrial Carbon Removal OpportunityRMI: Harnessing Carbon Removal Opportunities in Biomass Residue Building ProductsThe CO280 project Cara mentioned at a pulp and paper mill Hosted on Acast.

They Blame it on the Sun
Get bonus content at wickedproblems.earth! Why is it, every time the lights go out, anywhere in the world, there are ten influencers with pre-written posts about how it’s the fault of wind and solar on the grid? Whether it’s Spain in 2025 or Texas in 2021 or the UK in 2019 or South Australia in 2016 - before the lights are even back on, never mind an investigation, there is a lightning-fast squad of people who pop up on social media, in TV interviews, in newspaper columns, who claim with absolutely certainty that it was renewables. It was too much wind. Or too little wind. Or not enough sun. Or too much sun. Or all of the above - often in the same interview. It doesn’t need to make logical sense. It just needs to tickle your cortisol and dopamine receptors. Even if it affects the public debate - does it prevent steel going into the ground to build out more solar and wind in these places? And if it hasn’t to date, is that what's about to happen in Texas?Legendary climate and energy analyst Ketan Joshi returns to the show to hash out the whys and wherefores of it all. And what we might do about taking some of that pollution out of our information environment.Plus an unscheduled special guest appearance from our dogs.01:22 The 2016 Australian Blackout 02:17 Media's Role in Renewable Energy Perception 04:37 Technical Details of the Blackout 07:02 Public Reaction and Misunderstandings 11:24 Comparing Global Blackouts 13:27 The Role of Disinformation 18:16 Future of Renewable Energy and Grid Management 37:02 Meet the Dogs 37:59 Discussing Pre-Bunking 40:05 Wind Turbine Health Fears 45:03 Texas Renewable Energy Growth 52:23 Bluesky's Future Read Ketan’s Stuff His analysis in RenewEconomy.

Charles Perry: Does South Africa offer a warning against fossil fuel "indoctrination"?
We Start at the EndToday’s outro track is the COVID-era reboot of a classic Peter Gabriel track, featuring Yo-Yo Ma, Angelique Kidjo, and many more. The reason will become clear.In this episode of Wicked Problems, we sat down with Charles Perry, director of Sustainable Future for All, at the Conduit Club in London.A veteran in the climate and sustainability space, Charles has changed his views from evolution to revolution - a climate revolution akin to the Industrial Revolution. He reflects on his experiences spearheading renewable initiatives at BP, working with Al Gore, and advocating for justice-integrated environmental concerns.What set him on the path? A realisation once he left apartheid South Africa for university that the things he was taught were not necessarily how the world really was. That moment took him to anti-apartheid activism in South Africa and its democratic transition to climate advocacy and the need for a different paradigm on energy.Wicked Problems is a reader-supported publication. To receive new posts and support my work, consider becoming a free or paid subscriber.His direction of travel has been clear for a while - in that climate isn’t (just) a tech issue, but one as inextricably tied up with justice as the move was from slavery to fossil fuels.That kind of talk has gotten Charles into some bother before. Like his 2012 BBC interview with Jon Sopel that we clip in the ep.The conversation also explores Perry’s views on the moral imperatives of climate action, the obstacles posed by current political and economic systems, and the roles of influential leaders like Nelson Mandela and Al Gore in shaping his philosophy on sustainability.00:00 The Need for a New Revolution00:43 Introduction to Charles Perry01:02 Challenges in Climate Tech and Sustainability01:15 Charles Perry's Journey and Career01:52 Reflections on Working with BP and Al Gore10:58 The Intersection of Justice and Environmental Concerns18:47 The Unstoppable Sustainability Movement21:46 The Future of Energy and Sustainability25:19 Final Thoughts and Inspirations29:54 Conclusion and Call to ActionAll the OutrosThanks for listening.
