But the bottom line is....no matter what we do...no one can ever prove that any of it made a difference. It simply isn't provable.
Anytime the words, “may, might or could” is used to describe something as factual, it isn’t. And until the UN openly goes after China, climate science will remain a hoax.
Excellent point. We've been keeping temperature records across the globe since the late 1800's. Which is roughly the time the Little Ice Age bottomed out and we began yet another warming period (Modern Warm Period, see graph above). So the left gets away with saying highest temperatures "on record" in hopes that we don't realize that there were no temperature records of the prior warming periods (or that we forget the prior ones exist and thing the Modern Warm Period is unique).
