Excepting natural variability, temperature rise is in close alignment with net forcing. We need to ask what has happened to that forcing and what is the likelihood of future changes to the net forcing.
Sure, but one of the factors here is a reduction in low-level clouds, which has increased absorbed solar radiation. This could be a feeback to the external forcing, which might imply an acceleration, or it could be natural variability. I don't think we know the answer yet.
