This podcast is great. You will learn many many things. The host interviews thoughtful and articulate guests, and gives them the time to thoroughly discuss their arguments. I haven't gotten a new episode in a while - I hope that changes.
I first heard Corey Pein over at The Majority Report. He understands the gravity of the situation we are in. So thoughtful and well read, and is willing to actually go out there and do the hard work of journalism.
