While you're soaking up some sun this weekend, relax with this selection from Anthony Barnosky's  important book, Heatstroke. No one knows exactly what nature will come to look like in this new age of global warming. But Heatstroke gives us a haunting portrait of what we stand to lose and the vitality of what can be saved.

"Read this book, and reflect on your own views about humanity's place in nature. Then plant a tree, walk to work, and go and call your political representative." -Nature
