The segment tells the story of Roger Revelle, Al Gore, Maurice Strong and the UN IPCC. Revelle did early research on carbon dioxide as a greenhouse gas. He then had Gore as a student where Gore heard of the idea of global warming for this first time. Late scientist and teacher Revelle realized that CO2 is not a significant greenhouse gas, but Gore dismissed Revelle as senile and refused to debate. The UN's Maurice Strong fell into the trap of the same bad science and now the UN's Intergovernmental Panel on Climate Change holds on to its global warming claims despite the failure of its computer models to verify.
