  • Weekly: Why the climate crisis is an issue of injustice and inequality

    Weekly: Why the climate crisis is an issue of injustice and inequality
    Apr 18 2025
    Episode 299 In a climate justice special episode of the podcast, the biggest issue of the century is up for discussion. Find out the true impact of climate change on our planet and who should be paying to fix the crisis. Rowan Hooper and Madeleine Cuff are joined by two climate experts - Friederike Otto and Joyce Kimutai from the World Weather Attribution project at Imperial College London. This episode is dedicated to answering three questions - starting with the issue of climate attribution. To what extent can we blame climate change for extreme weather events like hurricanes, droughts, heatwaves, floods and wildfires? Find out how climate attribution began as a fringe science and how it has evolved to become a firm part of public consciousness. The next question is one of climate justice - how can we make sure rich countries pay for the loss and damage caused to poorer countries by climate change? The argument is that poorer nations are least responsible for climate change, yet they are most affected by its impacts. So at the latest UN climate summit, COP28, a lot of money was pledged - yet hardly any of it has actually materialised. So what’s going on? And the third question is about litigation - can climate attribution be used to achieve justice, by forcing climate polluters to pay up? A trial is ongoing where a company in Germany is being sued for its role in damaging the climate - but it’s still unclear whether the case will be successful. The hope is with climate attribution, it’ll be easier to bring cases like this forward and offer up a more detailed picture of how much damage has been done - and how much money is owed.

    Weekly: Have we really just found the strongest evidence for alien life yet?
    Apr 17 2025
    Episode 298 Big news has just broken - astronomers claim they’ve detected the strongest evidence for alien life yet. The news has got the world’s media fired up with excitement - but is this really a “revolutionary moment”? Astronomers studying the atmosphere of a distant planet called K2-18b say they have detected a molecule called DMS that is only produced on Earth by living organisms, so it’s thought life might be producing it there too. Hear from the lead researcher on this project, Nikku Madhusudhan of the University of Cambridge, who says “these are the first hints of an alien world that is possibly inhabited”. But even if this biosignature detection is confirmed, would it be the slam dunk everyone thinks it is? In this episode, Alex Wilkins and Rowan Hooper offer a bit of balance to the discussion and explore how far this is from definitive evidence of alien life. We also hear the views of Laura Kreidberg, managing director of the Max Planck Institute for Astronomy.

    Weekly: Dire wolves (not) brought back from extinction; US science in existential crisis; how to pour the perfect coffee
    Apr 11 2025
    Episode 297 The “de-extinction company” Colossal Biosciences claims to have brought dire wolves back from extinction. This is an ancient animal that roamed Earth 10,000 years ago and famously is depicted in Game of Thrones. After gene editing grey wolves, three pups have been born. But is it right to call them dire wolves, or are these just grey wolves in dire wolf clothing? It’s a turbulent time for US science, with massive and sweeping cuts being made to jobs and budgets. Departments like the National Institutes of Health and the Food and Drug Administration have been affected – raising major concerns about the future of public health in the country and beyond. Physicists have discovered the perfect way to pour a cup of coffee. Hot on the heels of the perfect cacio e pepe recipe and how to make the perfect boiled egg, this discovery is yet another hilarious hack that works in principle but is a massive faff. Chapters: (00:31) Return of the dire wolf (08:58) Turbulent time for US science (16:36) Perfect way to brew a cuppa coffee Hosted by Penny Sarchet and Timothy Revell, with guests Michael Le Page and Chelsea Whyte.
