Julia Whitty's newest article for Mother Jones magazine looks at potential global warming "tipping points" -- factors that could push us over the edge towards rapid climate change. What are those tipping points? How likely are they to happen? And will the coming turnover in the House and Senate have any impact on our ability to prevent them?

Plus, we explore whether the Congressional turnover means a change from the culture of corruption. Will the Dems prove just as corrupt as Tom DeLay and his buddies? We talk to Peter Stone, author of "Heist: Superlobbyist Jack Abramoff, His Republican Allies, And The Buying of Washington."

Also, author Nomi Prins spent years working at Goldman Sachs and other investment banking firms. Now she's telling the world how right-wing policies have taken their toll on your personal finances. We talk with her about "Jacked: How 'Conservatives' Are Picking Your Pocket (Whether You Voted For Them Or Not)."

And we speak with author and comedian Paula Poundstone, a former Mother Jones columnist whose new book is "There Is Nothing In This Book That I Meant To Say."

Finally, Morey Meniscus interviews outgoing defense secretary Donald Rumsfeld.
