'The Climate Majority' investigates climate apathy, to describe how it prevents action to stop climate change and to show how it can be beaten with an approach developed for political campaigns. Leo Barasi argues that dangerous climate change will only be prevented if the majority of people - including those who aren't environmentalists - are persuaded of the need to limit emissions. He applies his policy and campaign experience to show that politicising climate change makes it more difficult to build consensus, particularly among people who are currently apathetic.
