To prevent the catastrophic scenario of a planet heated by more than 2 degrees Celsius, 80 percent of the world’s current fossil fuel reserves need to stay in the ground. What’s standing in the way of making sure that happens? It’s not climate change denialism—it’s money. Those reserves are valued at an estimated $20 trillion, a number that seems impossible for fossil fuel companies to walk away from. “What does it take to make concentrated powerful interests relinquish their wealth on this scale?” was the question tackled on yesterday’s episode of MSNBC’s All In with Chris Hayes, as well as in his new Nation companion piece. The only time business owners have let go of a revenue source on that scale was when the United States ended slavery. It’s a tough mission, but as guest and Gasland director Josh Fox reminds us, “What is money worth when there is no civilization?”
