The United States has spent tens of billions of dollars on reconstruction in Iraq - but it might surprise you to find out what some of that money is really going towards. In tonight's Conversations with Great Minds - Thom talks with State Department veteran Peter van Buren about our government's bungled attempts to re-build a post-war Iraq. His new book is We Meant Well: How I Helped Lose the Battle for the Hearts and Minds of the Iraqi People.

Thom goes over the basics of what global warming is, what's causing it, and how we can stop it with climate scientist Michael Mann, author of the book “Dire Predictions: Understanding Climate Change.”

Dr. Michael Mann, Climate Scientist / Professor & Director-Penn State Earth System Science Center / Author-"Dire Predictions" and "The Hockey Stick and the Climate Wars" joins Thom Hartmann. Despite clear evidence of climate change occurring - the number of climate change deniers in this country is on the rise. Who is bankrolling the phony science behind the deniers - and why is there a war on scientific freedom underway in America?

Dr. David Korten, YES! Magazine/New Economy Working Group / Agenda for a New Economy joins Thom Hartmann. Our fossil-fuel driven economy is killing us and it's killing the one planet we call home. So how can we build an economy that protects the environment and grows the middle class - all at the same time?

Craig Unger, Journalist /Author, latest is "Boss Rove: Inside Karl Rove's Secret Kingdom of Power" joins Thom Hartmann. Karl Rove plans to spend as much as half billion dollars this election to defeat President Obama and Democrats. What's motivating him - and what happens to America if he succeeds?

Meanwhile - on the ground - teams of TEPCO workers began working in shifts to bring the melting down plant under control. These shifts were essentially suicide missions - as radiation levels were well above lifetime dosages. During that March - an estimated 900,000 terabecquerels of radiation were released into the air. That's roughly one-sixth of the radiation released during the Chernobyl nuclear crisis - but again - that was just during the month of March. Between then and December of 2011, when TEPCO finally said the plant was stable, more than 300 workers were exposed to lethally high levels of radiation - and millions of gallons of highly radioactive sea water were dumped into the ground and into the ocean.The effects of this radioactive dump are still not known.

In February of this year - TEPCO began pouring cement around the plant as part of the decommissioning process - a process that operators believe could take as long as 30 years. But despite assurances from TEPCO that the plant is stable - evidence shows the nuclear crisis is still far from resolved. The Unit 4 reactor building, with tons of radioactive fuel and waste still stored in its roof, is leaning - and in danger of toppling over and triggering a chain-reaction radioactive fire that could blow exponentially more radiation in the atmosphere than Chernobyl And radiation levels at reactor one recently reached all-time highs. Yet - Japan is moving forward with nuclear power. Just this month - a reactor at the Oi nuclear plant was turned on - marking the first time a Japanese nuclear reactor was operational since the March earthquake.

But the question is - have the lessons of Fukushima been learned? And not just in Japan - where the crisis continues and could yet worsen - but also in the United States? That's the topic for tonight's Bigger Picture discussion.... Joining Thom for Conversations with Great Minds are...Paul Gunter - the Director of Reactor Oversight Project at Beyond Nuclear - and 2008 recepient of the Jane Bagley Lehman Award for environmental activism - who's been on the front lines fighting back against nuclear power for more than thirty years now. And - Kevin Kamps - Radioactive Waste Watchdog at Beyond Nuclear - who's testified before the officials at the highest levels U.S. Federal Agencies dealing with radioactive Waste Management - including the Department of Energy, the Nuclear Regulatory Commission, and the EPA.

In this week's Conversatiosn with Great Minds - Thom Hartmann is joined by Professor Frances Fox Piven who envisioned the 99 percent movement over a year ago. For the past thirty years - she has been a professor of political science and sociology at the Graduate Center at The City University of New York. She gained notoriety for an article she co-wrote with sociologist Richard Cloward in 1996 that advocated increased enrollment in social welfare programs in order to collapse the dysfunctional parts of that system and force reforms - leading to a guaranteed annual income. This political strategy is now known as the "Cloward-Piven strategy" and has been a hot topic of discussion in recent years. Professor Piven has served as the President of the American Sociological Association and is currently an honoray chair of the Democratic Socialists of America. And she is one of the people responsible for the fact that you can now register to vote at the DMV - In 1983 she co-founded Human SERVE, an organization with the goal of increasing voter registration by linking vehicle registration with access to social services and voting. Human SERVE's initiative was incorporated into the National Voter Registration Act of 1993 - more commonly known as the "Motor Voter Bill" - and signed into law by President Bill Clinton. In addition to numerous scholarly articles, Professor Piven is the author of a dozen books - the latest being "Who's Afraid of Frances Fox Piven?: The Essential Writings of the Professor Glenn Beck Loves to Hate."
