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' 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 a disastrous, all-pervasive climate breakdown that will come as a hammer blow to global society and economy. Bill McGuire 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.
