Human contributions to global warming get a thorough examination in William T. Vollman's two-book series "Carbon Ideologies."
Volume 1, out now, is called No Immediate Danger, and its primary focus is nuclear energy. Which adds almost nothing in the way of greenhouse gases, but has its own considerable set of concerns.
The author traveled far and wide and even put himself in some danger to research the books.
He joins us with insights into his project and its findings.
