If the only facts that you know regarding climate science is that the earth was much warmer some number of years ago, and that the worldwide climate fluctuates, please try and refrain from repeating it again. You know less than 1/10 of 1% of what there is to know on the subject, and parroting the most basic, and obvious facts while leaving out the other 99.9% of the story to try and prove your point does not make you look intelligent; quite the opposite actually.
