It's pollution because it changes the way ecosystem works. That's the definition.
Unscientific, politically biased propaganda.
The carbon cycle is well understood.
No you're stupid. If humans change the concentration of CO2, the carbon cycle changes. That's all.
No, the carbon cycle does not change one bit. I don't think you even understand what you are saying. Even IF in worst case nutcase zealot Warmer the polar ice cap melted, the carbon cycle would not change.
However, if you actually believe that, support it with actual facts, instead of proclaiming people stupid.
