James Balog's photos chronicle climate change - "The Takeout"

Nature photographer James Balog has a message for climate change skeptics: Earth is changing and humans are responsible. His new book, "The Human Element: A Time Capsule from the Anthropocene," chronicles in pictures evidence of our changing world.   

"This is actually what some living human being with two eyes facing forward was able to see going on in his world.," Balog told CBS News chief Washington correspondent Major Garrett for this week's "Takeout" podcast. "I'm very conscious of the fact that I'm bringing back that visual evidence and saying, 'Here, you know, this is the reality.'"

Below are a sample of Balog's photos. His quotes are edited lightly for clarity.
