This statement is dead wrong.
If you believe this is true, how do you explain how humans have upset the balance of just about everything on this planet.
Example:
Species extinctions, Habitat destruction, depletion of natural resources, ozone layer weakening, (it reformed after we stopped using the chemicals that perpetuated the problem), pollution of the earth's atmosphere, and the list can go on and on.
If we can have such a negative influence, what makes you think we can't play at least a very small role in climate change? The data is there, its just whether you want to believe it or not. Frankly, I find it interesting you believe in the NWO (pretty much zero data to support that claim) but then you think we do have no impact on the planet. I'm not Al Gore, but we are certainly having an effect through a combination of pollution and habitat destruction that is having an influencing our climate. Yes, climate change is natural, so are a lot of the things I mentioned previously but we can alter the course of natural events. If you don't believe that, then you're ignoring FACTS.
