The climate models aren't really improving and to the extent they have the IPCC is getting less and less concerned. There is still quite a big spread between the predictions from no problem at all to world is ending.
You don't have to choose between my forecasting or the climate models you just have to understand how models work to realize that you aren't being as critically thinking as you might think you are.
The climate models are improving, but they all paint the same picture.
Between your non-speculative forecasting of "it's all going to be better" and our imprecise, albeit improving scientific models I choose science.
No critically thinking person would do otherwise in this case.
