U.S. government helped create global warming?

If you are a believer that global warming is man-made or not this is very interesting. I am not taking credit for this. I heard this on a radio talk show.

In the early 1970's the catalytic converter was introduced and later made mandatory on all cars sold in the U.S. The purpose was to reduce pollution. A catalytic converter's main purpose is to reduce pollution, converting a cars emissions to H2o and Co2.

Now Al Gore and his scientists are telling us that the world is warming because of Co2 emissions. So if he is correct the U.S. government has been a major contributor to this theory.

Very interesting to say the least. I would love to hear Al's response to this.
