Cool graphic from NASA. The Earth has been around for 4 billion years. When we have 1 million year's worth of temperature measuring, we might then be able to comprehend the Earth's environment on a geologic scale as well as human impact, if any.

And maybe when you've been around on this Earth for 200 million years you'll understand how pissed off most lifeforms are that we are quickly eradicating the places where they live.
