...You're missing my point.
Most scientists agree that the earth goes through periods of warming and cooling on its own and has for ages. WITHOUT human involvement. Thus our carbon emissions (or lack thereof) merely push the earth in one direction or other.
So if the earth is going to change regardless of human involvement why do we even care about how much CO2 we're dumping into the atmosphere??? A carbon tax isn't going to do squat besides put off the inevitable.
The end goal should be to learn how to control the cycle for our own benefit, because if the earth gets too hot or too cold -- either way it's a problem for our survival.
