"We could show you the evidence - which you wouldn't understand."
No, I'm betting that you can't.
Because noone yet has come up with irrefutable evidence that the current climate change is being caused by humans. Let me bold, underline, and capitalize that for you
NOONE
It's another one of those things like "God" that noone can prove because noone has enough information to prove it or disprove it.
Personally, I don't have an opinion on it, and was trolling because I'm bored and hungry. If you read Michael Crichton's "State of Fear", I'm basically reciting the character John Kenner's position on climate change. And even he at some point admits that there isn't enough information and that the studies are skewed due to politicization of the topic.
Just as I could not prove that it isn't happening, neither can you "environmentalists who know that their position is correct and there's tons of data but you don't have it handy because Tom dropped it behind the couch while we were rolling a J".
