Here is an entertaining and well researched video documentary from my friend John Coleman at KUSI-TV about the history of the Keeling Curve and its founder.
From the YouTube description:
A great scientist named Roger Revelle had Al Gore in his class at Harvard and the Global Warming campaign was born. Revelle tried to calm things down years later, but Gore said Revelle was Senile and refused to debate. John Coleman documents the entire story and shows how our tax dollars are perpetuating the Global Warming alarmist campaign even though temperatures have not risen in years.
