Hannah Ritchie’s second book, “Clearing the Air”, is out in paperback in the United Kingdom

After publishing Not the End of the World in 2024, Our World in Data’s Deputy Editor, Hannah Ritchie, published her second book last year.

Clearing the Air: A Hopeful Guide to Solving Climate Change — in 50 Questions and Answers is a guide for those feeling lost or overwhelmed by climate change, answering the most common questions about its solutions and how to make progress against it.

The hardback edition came out in September 2025, and both the Financial Times and the Sunday Times named it one of their best books of the year.

The paperback edition of Clearing the Air is published in the UK today.
