As climate change continues to take effect, we are all going to have to change the way we behave in order to survive. That's the conclusion of Eric Klinenberg, a professor of social science at New York University who's written a book focusing on the extreme 1995 heatwave in Chicago. Temperatures there hit over 41°C, killing hundreds of people. Klinenberg says it's not just infrastructure that will have to change, but the whole way we interact with our families and those living around us.
