All findings are peer reviewed if they are to claim scientific methodology. However, this means "peer" reviewed, not a PhD in economics reviewing climate science. 
And it means accepting that the qualified scientists ARE paid by universities. Many believe that if anyone paid finds proof of scientific claims, that they are just falsifying data to keep their job. Yet, other scientists could justify their pay by calling out the few who would risk their jobs by lying. That's not happening.
And speaking of lying. There were claims a few years ago that climate scientists had lied about global warming. These claims were refuted, but some don't believe the source  (FactCheck) http://www.factcheck.org/2009/12/climategate/
So they don't even look at the information. And, following  the trail takes time and attention in a country that prefers a tweet that captures the thoughts of a world leader. 
So people narrow their focus, ignoring ideas contrary to what they want to believe. Confirmation bias
