As stated last year, the Scenario B in that paper is running a little high compared with the actual forcings growth (by about 10 %)(and high compared to A1B), and the old GISS model had a climate sensitivity that was a little higher (4.2 ºC for a doubling of CO2) than the best estimate (~ 3ºC).

It's useful to think of this as an example of Bayesian priors in action — given that 99 % of the criticisms we hear about climate science are bogus or based on deep confusions about what modeling is for, scepticism is an appropriate first response, but because we are actually scientists, not shills, we are happy to correct real errors — sometimes they will matter, and sometimes they won't.
