Tony Robinson examines societies similar to our own, who not only survived climate change, but flourished.
In Peru the Hauri people embraced a savage drought, developed advanced techniques of water management and founded a great empire, itself the basis of the great Inca nation. In Europe, Tony learns how a mini-Ice Age triggered the Black Death; but rather than cripple medieval Europe it launched a period of unprecedented progression.
The Industrial Revolution and globalisation were hastened by the benefits of a stable climate, but Tony also learns how this stability appears to be ending, bringing a new threat to human societies.
