Actually, no. Your chart, by omitting the prediction range for each of those, does not speak to the original claim that "global warming is well below predicted temperatures".

It is not.

(And you should perhaps read that chart again if you think it is showing you that the "IPCC has been lowering predictions".)

It is just incredibly embarrassing that global warming deniers can't even read the reports which they so vehemently believe to be false.
