Warming is about to hit one and a half degrees, perhaps two degrees soon after. What do we do then? In the overshoot era, schemes abound for muscular adaptation or for turning the heat down at a later date, by means of technologies for removing CO2 from the air or blocking sunlight. Such technologies are by no means safe: they come with immense risks. Like magical promises of future redemption, they provide reasons for continuing emissions in the present. But do they also hold some potentials? Can the catastrophe be reversed, masked or simply adapted to, once it is a fact? Or will any such roundabout measure rather make things worse? This book maps the new frontlines in the struggle for a liveable planet and insists on the climate revolution long overdue. In the end, no technologies can absolve us of its tasks.
