Global climate change isn't an if anymore, it's a when, according to journalist Mark Hertsgaard.  The planet is going to get warmer, and Hertsgaard says that only the "climate crooks and climate cranks" are still in the denial business. But legislation is stalled in Congress because those very same crooks control the purse strings of the politicians who make the decisions.

How do the members of Generation Hot, like Hertsgaard's daughter Chiara, make it? Mark joined Laura in studio to discuss that and more in the second part of a two-part interview, this one focusing on the big picture, covered in his new book Hot: Living Through the Next Fifty Years on Earth.
