Ever since the beginning of the digital age, the proliferation of fake news and conspiracy theories has brought to light the banality of denial, in forms far broader than those of the clinics of psychosis, perversion or trauma. At the same time, the denial inherent in conspiracy theories seems to borrow some of its features from these clinical forms of denial, in its attempt to establish a viable position in the face of an intolerable and unrepresentable reality. The environmental crisis, in bringing the prospect of the end of the world and destructive fantasies to bear, is particularly apt at blurring the distinction between fantasmatic reality, fictional reality and historical reality. While the contents of theories of climate skepticism differ little from other incarnations of the conspiracist imagination, the environmental crisis nevertheless brings with it other specific forms of denial of reality. Not refusing the reality of the environmental crisis means acknowledging the radical nature of the loss of reality it entails, which raises the question of the extent to which it is possible, on a psychical level, to represent this loss of reality, and, on a metapsychological level, to grasp both its radicality and its unprecedented nature.
