We inhabit a planet in peril. Our once temperate world is locked on course to become a hothouse entirely of our own making. Hothouse Earth: an Inhabitant's Guide provides a post-COP26 perspective on the climate emergency, acknowledging that it is now practically impossible to keep this side of the 1.5°C dangerous climate change guardrail. The upshot is that we can no longer dodge the arrival of disastrous, all-pervasive climate breakdown that will come as a hammer blow to global society and economy. Bill McGuire, Professor of Geophysical and Climate Hazards, explains the science behind the climate crisis, painting a blunt but authentic picture of the sort of world our children will grow old in, and our grandchildren grow up in; a world that we catch only glimpses of in today's blistering heatwaves, calamitous wildfires and ruinous floods and droughts. Bleak though it is, the picture is one we must all face up to, if only to spur genuine action - even at this late stage - to stop a harrowing future becoming a truly cataclysmic one.
