Increasingly, human beings are city dwellers. More than half the global population lives in an urban area, and the rates are increasing. Some new urban residents may be fleeing rural areas vulnerable to the impact of climate change. But are they likely to fare much better in the city when it comes to climate impacts? And are fast-growing cities around the world prepared to confront environmental challenges that come with rising populations? This episode discusses these questions with noted climate expert Neil Adger, a professor of human geography at the University of Exeter.
