The inability for seemingly intelligent people to grasp why this argument is wrong really frustrates me. Yes, the earth has had countless cycles of heating and cooling which preceded and had nothing to do with humans. That does not preclude the possibility that the current changes we are observing are anthropogenic. That’s like saying “the wind has blown my screen door open in the past. Therefore if I hear it open today, it is impossible that it’s because a person entered”. The most grating part is how smugly this ridiculous argument is put forth, as though the debate has just been decisively settled.
