The temperature WILL increase, and it will decrease. It has throughout history so I am sure we'll get a chance to witness that. Our ancestors have. Yet blaming the occurrence upon man is just them creating a new religion that you are not allowed to question. You'll be a heretic, a blasphemer, an infidel!!! Oops... that isn't the word they use. They'll just call you a denier and advocate for you being silenced, jailed, fined, and even executed. Gotta burn the witch.
