My body also has a balancing system. When it gets hot, it will transpirate more, which allows my body to remain at regular temperature even in places where the temperature is higher than my body temperature. In the same way, the earth has balancing mechanisms although they work a bit slower than the body. One of these would be that, with a higher temperature, more water evaporates into the air, which shields the earth from sunlight and thus additional warmth.

Anyway, you said >A single counter-example can never show a limit to anything.

I beg to differ. I can agree with you to the point that a single counter-example cannot ever show WHERE the limit is, but a single counter-example can surely show that there ARE limits. If I were to give an example of this, would you argue that its just one example and therefore invalid?
