A snapshot is that most climate models tend to fail on prediction. The model developed by Zharkova et al gives a close prediction to actual sunspot activity:

This model allowed them to create a formula which could be used to predict what the sunspot activity would have been in the past (eg. the little ice age) as well into the future:

Depending upon the veracity of this model, instead of global warming, we are actually heading toward a short period of cooling ... similar to that found during the Maunder Minimum.
