Earth then and now records the dramatic changes that our planet has undergone in just the past 100 years. Drawing on the archives of print, picture, and space agencies, this compelling book presents issues such as climate change in a powerfully visual form. A collection of 250 stunning images showing locations around the world as they were and as they are now. Each pair of photographs or satellite images has been selected to tell a thought-provoking story-of a melting glacier, an ever-rising cityscape, or a volcanic eruption-presenting a stark, visual comparison that is sometimes breathtaking, sometimes shocking, but always fascinating. Concise captions explain the facts and leave us to draw our own conclusions about the Earth Then And Now, and to meditate on the earth to come.
