Elizabeth Kolbert investigates the history, and future, of climate change – from A, for Svante Arrhenius, who created the world’s first climate model in 1894, to Z, for Net Zero. Along the way she looks at Greta Thunberg’s ‘blah blah blah’ speech, flies an all-electric plane, experiments with the effects of extreme temperatures on the human body, and struggles with the deep uncertainty of the future. Complemented by Wesley Allsbrook’s gorgeous, colour illustrations, H Is for Hope offers an inspiring, worrying and, above all, hopeful vision for how we can still save our planet.
