There are families of models that focus on different things, each family with a number of members that have differing paremeter weightingss, etc.

Yes, there are big overviews of the models and how they differ - the IPCC look at the over|under predictions of all the models and look at the spread and assumptions to select a "most probable" middle ground prediction for climate going forward.

For example while the current year has been warmer than expected it's also been cooler than a number of worst case scenarios that assume faster methane releases and water vapor increases, etc.

I had a goto link for a good overview .. currently it's redirecting to:
