[Old School]

For quite some time, researchers and cognitive dissonants
alike said that linking smoking to cancer was nothing more
than scare tactics, scary scenarios, etc. I don't know
a lot about scenarios, but I know this: crowded bars trap
smoke...I've got to believe that millions of cars spewing
smoke into the atmosphere is not some benign, "of no real
effect" matter...the industrial revolution has not been
kind to the environment...ever fished in an acidified lake?
Nope...ain't no life there...believe as you will (and that's
what we do)...but common sense tells us this fossil fuel
party does NOT come without a cost...

Water Vapor which is responsible for 95% of Earth's greenhouse effect is 99.999% Natural. Even if we wanted to we there's nothing we can do to change this.

Anthropogenic (man-made) CO2 contributions cause only about 0.117% of Earth's greenhouse effect, (factoring in water vapor). Adding up all the man-made greenhouse sources the total human contribution to the greenhouse effect is around 0.28% (factoring in water vapor),

The Kyoto Protocol calls for mandatory carbon dioxide reductions of 30% from developed countries. Reducing man-made CO2 emissions this much would have a undetectable effect on our climate, while having a devasting effect on our economy. Can everyone reduce their driving by 30%? Can everyone reduce their winter heating by 30%? Prices on every day products would raise by about 40%. Even if we were to reduce the CO2 emissions by 30% it would only change the greenhouse contributions by 0.035%.

The CO2 in our atmosphere has been increasing steadily for the last 18,000 years...long before humans invented the automobile
