No, it says that we need to heat the planet by a whole lot more because noone should ever have to endure minus twenty!
There were a couple of things I remember from school science many moons ago and that is that if you blame cause and effect on something (for arguments sake CO2) and you produce significantly more of this substance in a period of time, (lets say 16 years) then surely the effect of doing that (heating as you insinuate) would accelerate rapidly.
Instead we haven't seen that from the data released. The weather changes. Get over it.
