Tony Robinson traces how global warming at the end of the last Ice Age was the catalyst for the dawn of civilisation, but also unleashed devastation. Twelve thousand years ago our planet emerged from the last great Ice Age, with temperatures rising by five degrees in just a few decades. After 190,000 years living as nomadic hunter-gatherers, our ancestors were forced to change with the world around them. In Europe the rise in temperature unleashed an agricultural revolution, while in North Africa around 7,000 years ago a savage drought led Saharan refugees to settle along the River Nile. In the limited space they had to learn new skills and form new social structures, going on to found the Kingdom of Egypt. Five hundred years later this same global warming triggered catastrophe as Canadian ice sheets containing 900,000 trillion tonnes of water melted into the Atlantic, causing massive flooding. In less than a year Britain was amputated from mainland Europe, and the Black Sea was formed, washing out the pioneer farmers from that region. What happened to the people that had cultivated this fertile land changed the future of the continent.
