Yes the Earth's climate has changed before. Yes the Earth's climate will probably change again with or without human interference. That does not mean humans can not affect the Earth's climate. Nor does it mean the current changes are not anthropic in origin.
If you want to educate yourself about the evidence for anthropic climate change and the likely consequences, the IPCC Fifth Assessment Report would be a good place to start.
Anthropic......you think the climate is changing because of us, or do you think we are accelerating change that was already occurring?
The evidence says the climate is changing because of us. It also says that solar irradiance is down since 1980. Since solar irradiance provides most of the energy for the Earth's climate then all else being equal the climate should have cooled instead of warmed since 1980. But it did not. It did not because of human activity mostly in the form of the release of CO2 into the atmosphere.
