An idealistic 20-something environmentalist versus a retired right-wing finance minister: this is the story of Anna Rose’s whirlwind journey around the world with climate skeptic Nick Minchin.

From a remote Hawaiian volcano to a cosmic ray laboratory in Geneva, Anna rolls out the biggest names in science to try and change Nick’s mind. As it examines what’s happening to the Earth’s climate, this book offers opposing points of view as Anna and Nick challenge each other’s opinions, leading them to confront closely held assumptions and to question human responsibilities as citizens living in uncertain times.
