However, the tracking between Scenarios and actual temperatures is best for Scenario C. Which is to suggest: 1) the emissions have virtually no impact at this time on global temperatures, or 2) all of the impact of emissions since 2000 has been offset by natural processes that have not been modelled.

I have still not found the details for the model run that produced fig. 7 in Hansen et al. (2011) but I have looked at some 100 year responses to 2x, 4x, and 8x carbon at the GISS web site and I am thinking that I am on the right track in clearing up this itch: The climate response function gives us a way to calculate the average temperature given a forcing without doing a whole model run for that.

Climate models, on the other hand, have a successful track record — look at the melting Arctic, warming around Antarctica, the surface temperature, the water feedback effect, the reduction in mountain glaciers... etc..

Given the large uncertainties in forcings and model inadequacies (including a factor of 2 difference in CO2 sensitivity), how is it that each model does a credible job of tracking the 20th century global surface temperature anomalies (AR4 Figure 9.5)?

Tracking sea surface temperature over a long period is arguably the most reliable way researchers know of measuring the precise rate at which global temperatures are increasing and improves the accuracy of our climate change models and weather forecasts.

However, temperatures in recent years — both during the El Niño event and, more importantly, now that the El Niño event is over — are tracking rather close to the average projection of the climate models included in the latest report from the Intergovernmental Panel on Climate Change (the CMIP5 models).

Since ocean temperature anomalies in the canonical Niño 3.4 region are now above 2 C — which are record values for the calendar month and not too far from their highest values ever observed at any time of year — current observations in the real world suggests that the models are very much on track.
