“a new atmosphere-ocean climate modeling study”
Garbage in, garbage out.

Exactly. All those computer models make the fundamental assumption that CO2 causes the fluctuation of levels of water vapor which is the really effective greenhouse gas. It’s pretty much a guaranteed case of getting the results you have created the model to generate. In fact no other outcome can be derived from the models owing to the assumptions built in. One can easily note that every single one of the modeling studies predicts increases in temperature, only varying in degree. None of them ever predict dips in temperature (which is what is really seen).
Even modeling software must be tested and proven. Until it is, no software can be trusted -- especially modeling software. Until they can show that their model can reproduce current conditions from a starting point in the past, their results cannot be taken seriously.
