The three episodes of this documentary are entitled Denial, Doubt and Delay.
It shows former Republican Senator Chuck Hagel reflecting on his role in blocking US ratification of the Kyoto climate treaty. A quarter century later, Hagel acknowledges that fossil fuel companies manipulated Congress with a flood of false information, and accuses the oil industry of maliciously claiming that the science of climate change was unproven when companies like Exxon and Shell already knew otherwise from their own research.
