Last year, the astrophysicist Adam Frank implored an audience at Google that we see climate change – and the newly baptised geological age of the Anthropocene – against this cosmological backdrop. The Anthropocene refers to the effects of humanity’s energy-intensive activities upon Earth. Could it be that we do not see evidence of space-faring galactic civilisations because, due to resource exhaustion and subsequent climate collapse, none of them ever get that far? If so, why should we be any different?

A few months after Frank’s talk, in October 2018, the Intergovernmental Panel on Climate Change’s update on global warming caused a stir. It predicted a sombre future if we do not decarbonise. And in May, amid Extinction Rebellion’s protests, a new climate report upped the ante, warning: “Human life on earth may be on the way to extinction.”


… apocalyptic prophecies are designed to reveal the ultimate moral meaning of things. It’s in the name: apocalypse means revelation. Extinction, by direct contrast, reveals precisely nothing and this is because it instead predicts the end of meaning and morality itself – if there are no humans, there is nothing humanly meaningful left.
