The program referred to four decades of cooling, not 40 years, which entirely corresponds with 35 years. They fabricated nothing there, you however have misunderstood the meaning of a decade or have yourself interpreted information for your own cause.

Anyone want to comment on how CO2 has such a dramatic effect when it is only constitutes 0.03% of the Earth's atmosphere?

CO2 has a 'forcing' effect, not just 'feedback'. Consider the concept of a 'catalyst', a small quantity of something which causes a big effect.

Have you seen this: http://www.ipcc.ch/SPM2feb07.pdf

Global atmospheric concentrations of carbon dioxide, methane and nitrous oxide have increased markedly as a result of human activities since 1750 and now far exceed pre-industrial values determined from ice cores spanning many thousands of years (see Figure SPM-1). The global increases in carbon dioxide concentration are due primarily to fossil fuel use and land-use change, while those of methane and nitrous oxide are primarily due to agriculture. {2.3, 6.4, 7.3}
