Yes there's a lot of existing models, and a lot of the existing models have been wrong in the past. Climate science has always been very politicized. I for one would welcome predictions from people who have a track record of predicting things correctly. Climate science has a mixed track record [0].
FWIW, I'm very much NOT endorsing cei.org, nor saying climate change is not a big problem. Just saying that the track record of climate scientists is not great. Climate change is important enough to warrant the attention of people who can actually predict things.
