Paul Jay speaks to Jessy Tolkan at the Tides Foundations' Momentum conference in San Francisco. They speak about Tolkan's coalition on climate change fighting Obama to establish a moratorium on all coal mining. Tolkan says that Washington's push for "clean coal" is not enough because the coal industry's and President Obama's argument that the production of coal can be clean is "an absolute, 100% lie." She also says that "the science is clear that if we don't address coal head on, it's almost "game over" for the planet."
