Episode 386 The climate crisis is having a significant impact on yields of crucial food crops. Losses of maize, wheat and soybeans alone are costing $20 billion a year due to heat and drought. New estimates expect this to rise to $160 billion per year by 2100 - although that could be an underestimate. While this means food prices will keep on rising in developed countries, the majority of the population in the world’s least developed regions work in farming, so crop losses have the potential to destabilise them, creating social unrest and increased migration. But beyond getting emissions under control, do we need to completely rethink how we produce food globally in order to combat this?  Rowan Hooper and Penny Sarchet are joined by Michael Le Page to discuss this new prediction and the action needed to stop it coming true.

  • and a new analysis suggests that this could rise eightfold to more than $160 billion a year by 2100,

  • We've already seen a big increase in food prices over the last few years.

  • And there's been a sort of shifting baseline, hasn't there?

  • Because they've gone up and gradually a lot of us get used to it.
