That's the issue. (I upvoted you btw) That the climate is going through a short period of less than stable behaviour is certainly evident. It's also evident that it's gone through such behavior in the past, with both more and less variance. There have been ice ages FFS, and that had nothing to do with man.
It seems like we are having an influence in our current whether patterns, but we simply have nowhere near the amount of data to know this beyond theory.
To say that we are - without doubt - causing the earth's climate to change when we can't predict the "change" accurately is scientifically irresponsible.
