The planet is heating up, every plan to stop it has fallen short, and growing group of scientists has started to ask a stranger question: what if we grabbed the thermostat ourselves? Ben Bradford investigates geoengineering — the science of deliberately manipulating Earth’s climate — from space mirrors and ocean fertilizers to fleets of planes mimicking a volcano. Some of it sounds like cartoon villainy. Some of it might actually work. And that raises the thornier question: if humans can cool the planet on purpose, who decides whether we should?

Guests:

Kate Ricke, climate change scientist at UCSD

Alan Robock, atmospheric scientist at Rutgers

Imagine a friendly assistant that can help you build a bioweapon. Or a chatbot in the nuclear weapons chain, cheerfully hallucinating an attack. AI national security expert Hamza Chaudhry worries this is the biggest threat right now — not “killer robot,” but humans being humans. Because whether AI becomes dangerously smart or confidently dumb, people will find face-palming ways to abuse it. From deranged cultists and rogue states, to stockbrokers and the most evil version of Ben’s little cousin, handing everyone a powerful technology with few guardrails could end badly. Or, is there a path to convince companies to add their own?

Are we living through the end times or the best moment in human history? Novelist and internet veteran Jason Pargin argues you have spent your life inside a “literal reverse apocalypse” — and if you don’t see it, he knows who to blame. Ben Bradford talks with Pargin about doom-scrolling, child mortality, processed donuts, murderous Toyota drivers, and how humanity’s greatest problems may be side effects of its greatest successes. So how do we tell if the world is really ending — or if the internet has trapped us inside a giant doom machine?
