It's well known that the earth would be much colder, if CO2 didn't exist.
Do you really believe that? If you do, I put it to you that you are not using your mind at all but merely following the dogma that a high priest has preached to you. Here, let me give you an opportunity to actually use your intellect in a small bit of critical observation.
You say that the earth would be much colder if it weren't for CO2. I say that the exact opposite is true and anyone who is capable of using his mind must come to the same conclusion. The fact is that the atmosphere (primaraly water vapor) keeps us cool during the day, and slows the inevetable cooling that night time brings.
Consider the moon. It is roughly the same distance as us from the sun and as such recieves roughly the same amount of energy per square meter from the sun as earth except it has no atmosphere. Ask yourself. On the moon, what is the consequence during the day of having no atmosphere? What is the consequence during the night of having no atmosphere.
During the day, the moon, which has no atmosphere and recieves roughly the same amount of energy per square meter as the earth, the temperature is over 250 degrees F. Compare that to the hottest place on earth and you can't help but agree that during the day, the atmosphere keeps us from buring up.
During the night, the moon which has no atmosphere to slow the convection of heat absorbed by its surface into space drops to a chilly -387 degrees F very quickly.
If you still believe that the atmosphere keeps us warmer than we would otherwise be without it, explain the searing daytime temperatures on the moon.
So what's so hard to understand that more would result in even more warming, despite the fact that it's a trace gas?
Rather than answer that I will ask you if you still beleive that the atmosphere keeps us warmer than we would otherwise be without it? If you do, then clearly you are not using your mind.
If its absolute concentration was important, why would it contribute to warming at all? That's the problem with the deniers' positions. When looked at carefully, they just don't pass the logic test.
The problem lies with your position as it opposes all observed evidence. The foundations of your position are proveably wrong. Your entire position rests on the idea that the atmosphere, namely CO2 somehow keeps us warmer than we otherwise would be without it, but the moon, our nearest neighbor, sears under the light of the sun with no atmosphere. What makes you believe that the earth would burn under the sun the same as the moon if there was no atmosphere to keep daytime temperatures down to a liveable level?
