In this episode of Tech Tonic, we ask whether AI's potential in the fight against the climate crisis justifies the massive amounts of energy it takes to run these systems. The computing power required to train AI concerns some researchers, who have built a calculator to count the tech's carbon footprint. But AI advances have also opened new avenues to fight climate change, by helping Arctic scientists, weather modellers, and green energy gurus. This week the FT’s innovation editor John Thornhill and environment and clean energy correspondent Leslie Hook, debate AI’s climate effects. We also hear from Jennifer Jackson, a molecular biologist at the British Antarctic Survey, and Sasha Luccioni, an AI researcher at Mila research institute in Quebec.
