Mark Lynas delivers a vital account of the future of our earth, and our civilisation, if current rates of global warming persist. And it's only looking worse. We are living in a climate emergency.

Rigorously cataloguing the very latest climate science, Mark Lynas explores the course we have set for Earth over the next century and beyond.
