‘I do not understand my own actions. For I do not do what I want, but the very thing that I hate’ (Romans 7.15). Climate change creates a striking gap between our professed beliefs and ideals and our actual practice. Even the greenest Briton is pumping more than her fair share of carbon into the atmosphere. All of us want something to be done about it, yet very few of us want to do anything about it ourselves. We are highly anxious about the threat; yet we seem incapable of changing our lives in any fundamental way. Our first task, then is simply to try to understand this inconsistency a little better.
