Data centres are not the most glamorous topic of discussion but they are everywhere, powering our modern, digital economy. But they can also power swimming pools, breweries and laundries, as Mark Bjornsgaard tells Hannah and Rob on this episode. 97% of the electricity that goes into a computer comes out as heat. It’s an incredibly inefficient process, and more often than not this heat isn’t used. So, rather than building these data centres in the middle of nowhere, Mark’s company Deep Green is taking computing power to where heat is needed, offering a precious resource to communities across the UK. Could this be scaled up for use across the world?

Despite the inexorable growth of Generative AI tools such as ChatGPT or Midjourney in the past couple of years, painfully little is known - or at least publicised - about their carbon impact. However, Dr Sasha Luccioni is on a mission to change that. Hannah and Rob talk to her about how she’s trying to maximise the benefits of AI, while minimising its hidden climate costs. Why is AI development such a black box? And could AI be part of the solution to the climate crisis?

How do we buy ourselves some time to save our planet? Humans are responsible for the immense damage inflicted on our planet since the Industrial Revolution, but now we have the chance to do some good and repair the climate. Hannah and Rob discuss the power of human ingenuity and ambition with Founder of the Centre for Climate Repair at Cambridge University, Professor Sir David King. His work finding ambitious solutions to the climate crisis can sound almost unreal. Making clouds brighter to reflect more sunlight? Refreezing the arctic? Using whale poo to regenerate the ocean’s biodiversity to store more carbon? He joins Hannah and Rob explore these solutions and more in this week’s episode.
