Arrogant? It's arrogant? You might want to read up on the effects of higher CO2 levels on human cognition. It's not pretty. And it completely blows your comment out of the water.

The only question is whether we will do something about it before it is far, far too late. You need to worry about the next 50 years before you start worrying about 500 million years.
