Coolinator (if he were still around) would post
this link, and state "wha-BAM!"
Problem is, he would be wrong. The study does not refute global warming, it just indicates that there is still much about climate change that is still not modeled appropriately, or even completely understood.
The author even states that his work is being misrepresented by the "non-scientist blogosphere".
Still, it is interesting, and topical.
