There are PLENTY of university studies that are total BS. Unless it is repeatable, it will generally not have much credibility. 
Even now, when I read about studies or developments by chinese professors here in America, I discard them because so many are total BS. 
I posted earlier here another link that showed how wrong that dog garbage was. 
Sadly, it is used by far right wingers to claim that far lefties with pets are hypocrites. 

And as to denier of AGW, no. I am a scientists and have seen more than enough in the environment to KNOW that it is getting warm. In addition, far too many REAL scientists have done the work and have shown that it is real.
Only fools/idiots think that AGW is not real. 

Now, as to the long-term impact to humanity, that can only be conjecture. Some things are going to be spot on, but a lot of it is politicians making up stories.
