For 25 years, photographer Peter Essick has traveled the world for National Geographic magazine, with many of his recent assignments focusing on the causes and consequences of climate change. In a Yale Environment 360 photo essay, we present a gallery of images Essick took while on assignment in Antarctica, Greenland, and other far-flung locales. The photographer says that what most struck him was the dedication of the scientists who have committed themselves to documenting the effects of global warming.

“Everyone I talked to felt that they were uncovering evidence for climate change and that the threat for the future was increasing,” says Essick.









Peter Essick is a photographer and frequent contributor to National Geographic magazine. His latest book, which covers climate change and other environmental subjects, is Our Beautiful, Fragile World
