Are you denying that North America was covered with an ice sheet a few thousand years ago?
We're pointing out how cowardly and stupid you look for trotting out that pathetic evasion every time you get spanked by reality. It's an amazingly stupid basic logic failure on your part. The present is not required to act like the past, especially when conditions in the present are wildly different from conditions in the past.
In the manner of patiently explaining things to a slow child, this has been explained to you, over and over. Since you refuse to grasp the obvious, it means you're either an imbecile or a cult liar. Either way, that means the correct response to your 'effed-up logic is to point and laugh, which would be why the entire planet is doing so.
And that statement shows just how scientifically crippled you are. The AGW cultists have made a extraordinary claim that man is the root cause of all the weather happening today. We have stated that it is all natural cycles and variability. We have millions of years of history on our side. You don't.
It is up to you to prove your statement. So far, you have failed, and failed so miserably that your side has resorted to extreme unethical behavior and outright fraud to perpetuate your claims.
Occams Razor is on OUR side.
