Just out of curiosity, is there any reputable scientist (other than Al Gore) who believes that global warming IS caused by man?

Al Gore is not a scientist, let alone reputable.

I’m not sure Algore earned a degree in anything during his college career.

If al bore would spend as much time and effort with his family as he does promoting himself maybe his son would not have as much trouble as he has now.

Oh well, I suppose al has his own ideas which is more important. So sad.
