Seems like the models have quite a few holes. It made me wonder if anyone has considered making a complete list of assumptions that are baked into these models, so they can be looked at in detail.
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:
The Lawrence Livermore National Laboratory is working on our digital Special Collections and the connection with OSTI. This includes all LLNL produced Technical Reports, Theses & Dissertations, and eSholarship content. We are working at making these available through OSTI. We apologize for the interruption in service.Yes, they did, it's called an "ensemble model" when multiple models are collated to account for their different modelings.
A friend of mine did his physics PhD on cloud formation at a molecular level exactly to tackle the issue some models had to account for that over longer time scales, most of the holes you can think of from the top of your head have been considered, there are many thousands of very smart people working on these models for the past 30-40 years.
