"Consuming foods with ingredients derived from GM crops is no riskier than consuming foods modified by conventional plant improvement techniques."
The primary conclusion is that for a number of claims that are generally held to be true by consensus, opposition to those results show interesting correlations: opposition correlates negatively with objective knowledge (what the final test indicated that the subject knew about the field), and positively with subjective knowledge (what the subject thought they knew about the field). Those who were most opposed tended to exhibit a large gap between what they knew and what they thought they knew.
Here's the list of subjects and then I'll get to the punch line:
Which one wasn't like the others?
Climate change!
The question was in the same vein as the rest:Most of the warming of Earth’s average global temperature over the second half of the 20th century has been caused by human activities.
Unlike every other field listed in this research, there was a slight positive correlation between opposition to the claim and objective knowledge of the subject (see figure 2).
What other consensus viewpoints are out there where agreement with the consensus correlations with greater ignorance of the subject? Economics maybe?

So of the 17 model projections, the last four or so are actually massive aggregations of models. And the report found problems with the IPCC aggregates. On page 5:
For IPCC FAR and IPCC TAR (note they are referred to as "models"), it was stronger, a typical symptom of "running hot" bias. Notice also the use of an "implied TCR metric" throughout the paper to ignore these differences.
A typical policy question is when you emit a certain amount of CO2 equivalent, what global temperature increase do you see? By going to a purely radiative forcing viewpoint, they ignore both the increased removal of greenhouse gases from the atmosphere and the positive feedback mechanisms that are supposed to result in higher temperatures in the long term. But that's a huge part of the policy decision!
To be blunt, your link was significantly dishonest. It alleged to compare 17 "models", but we find that it's actually comparing hundreds with at least two large aggregates showing the consistent bias problems I discussed earlier, and emphasizes metrics that hide those bias issues.
