Data scientist Hannah Ritchie has written a good-hearted, generous book that tries to reassure us about the various environmental crises we face. Which, obviously, is much appreciated: God knows we need all the optimism we can get.
Ritchie is lead researcher at the groundbreaking Our World in Data, a website run out of Oxford University. She describes the moment of revelation when, after years of feeling helpless and anxious, she discovered the Swedish professor Hans Rosling, and “everything changed”.
