The recent paper by Ineson et al. presents climate model computations for the global temperatures up to 2100. As a novelty vs. other simulations, the computations include a variable sun output with assumed Maunder minimum-like conditions by 2050. They conclude that a decreasing sun activity will not save us from the most of the up to +6.6 o C global warming by 2100 that is the upper range of the climate model predictions. We show the evidence of nearly constant temperatures since 1988 that are in complete disagreement with the climate model predictions also in their lower range, and the almost constant solar activity since 2003. We conclude that the so called climate models, in reality a very simplistic correlation of global temperatures to the carbon dioxide emission, having failed to predict the observational evidence over this century, for no reason will do any better for what is left of this century. We finally note the logical impossibility for global warming to continue at the same time as a little ice age.
