97% of climate scientists believe that climate change is, in no small part, attributable to Man.

The article suggests a 2.5 degree C change, which is listed as a more moderate model. The high end suggests 3.5 C and the low end is about 1.8 C.
2.5 C = 4.5 F
3.5 C = 6.3 F
1.8 C = 3.24 F
I imagine this model is more in the consensus range you are looking for. That consensus changes as more data becomes available. What doesnt change is the fact that we are warming and that Man is mostly responsible.
