Each pair of photographs has been selected to tell a compelling story. Melting glaciers, expanding deserts, ever-rising cityscapes or natural disasters present stark visual comparisons. On one page, you are shown a part of the world as it was five, ten, twenty, fifty or even more than one hundred years ago. On the facing page, you see the same place as it looks today. Concise captions explain the facts and then leave you to draw your own conclusions about the Earth then and now, and about the Earth’s future.
