Our World: By the Numbers

"This book opens wide on the solar system and then zooms in on planet Earth--its history, its creatures, its climate, and its future. Discover some of the most fascinating aspects of our world through astonishing numbers: the stretch of time from Earth's formation to the present, how often lightning strikes in one day, the temperature at the center of the sun, what percentage of Earth's land is covered in deserts or forests or cities, and so much more"--
