Brexit, we are endlessly told, is a “crisis”. Hardly. Climate change is a crisis, and one that will make the political events of recent weeks seem like a toddler’s tantrum. So, what do we do?

First, we could think. Roger S. Gottlieb’s Morality and the Environmental Crisis (Cambridge University Press, £22.99; Tablet price £20.69) underlines how our environ­mental crisis runs deep: not simply a political or social problem but a philosophical, moral and spiritual one. Drawing on a lifetime of work as a pioneer of religious environmentalism, Gottlieb integrates religious, philosoph­ical, scientific, and political ideas into an admirably perceptive and balanced analysis of our predicament.
