“I’m sorry we broke the sea and sky and shortened the wings of the nightingale. I’m sorry that the Great Barrier Reef is no longer great, that we value Amazon much more than the Amazon.” Those are the words of CNN’s chief climate correspondent Bill Weir from his new book called “Life as We Know It (Can Be).” He wrote it as a letter to his 4-year-old son River to read in the future. It’s a future where he hopes we’ve fixed our broken climate. Bill Weir, who began his career in Austin, shared more about the book on this week’s Climate Cast.
