Clive Hamilton has a riveting essay in a new book edited by psychoanalyst Sally Weintrobe, Engaging with Climate Change, which had its origin at an inter-disciplinary conference at the Institute of Psychoanalysis in London a couple of years ago. Hamilton’s subject is what history can teach us about climate change denial. He begins with the deep polarisation of US society and the way in which global warming has become a battleground in this wider culture war. The implications of climate change threaten conservative cultural identity. Not that liberals are less likely to sift evidence through ideological filters, but in the case of global warming the evidence overwhelmingly endorses liberal beliefs that unrestrained capitalism threatens future well-being, that government intervention is needed and the environmentalists were right all along. In Europe, the absence of a long and rancorous culture war explains the relative weakness of climate change denial.
