Changes in Earth’s orbit as well as inclination obviously do have an effect on the climate here on Earth, that does not mean that man’s activities don’t also contribute to climate change.

Indeed, consensus amongst the planet’s most respected scientists is that man is the major contributor towards climate change.

Just because we can expect the climate here on Earth to change over millennia due to solar and planetary movements does NOT mean that we can continue to behave in a way that is causing it to change in a matter of decades.
