On previous estimates of the climate sensitivity, that is far too late.

The series of reports concludes: «The recent pause in global surface temperature rise does not invalidate previous estimates of climate sensitivity.

Note that 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) and as stated in previous years, the actual forcings that occurred are not the same as those used in the different scenarios.

Whether the observed solar cycle in surface temperature is as large as.17 K (as in Camp and Tung) or more like.1 K (many previous estimates) is somewhat more in doubt, as is their interpretation in terms of low thermal inertia and high climate sensitivity in energy balance models.

Actually Olson et al's abstract states «Our results are consistent with most previous studies» and «The mode of the climate sensitivity estimate is 2.8 °C, with the corresponding 95 % credible interval ranging from 1.8 to 4.9 °C» (which supports the first quote).

As we discussed at the time, those results were used to conclude that the Earth System Sensitivity (the total response to a doubling of CO2 after the short and long - term feedbacks have kicked in) was around 9ºC — much larger than any previous estimate (which is ~ 4.5 ºC)-- and inferred that the committed climate change with constant concentrations was 3 - 7ºC (again much larger than any other estimate — most are around 0.5 - 1ºC).

Hegerl et al (2006) for example used comparisons during the pre-industrial of EBM simulations and proxy temperature reconstructions based entirely or partially on tree - ring data to estimate the equilibrium 2xCO2 climate sensitivity, arguing for a substantially lower 5 % -95 % range of 1.5 — 6.2 C than found in several previous studies.

What's new is that several recent papers have offered best estimates for climate sensitivity that are below four degrees Fahrenheit, rather than the previous best estimate of just above five degrees, and they have also suggested that the highest estimates are pretty implausible.

Until we have an actual way of measuring climate sensitivity, these guesses merely recognize that the previous estimates, which were claimed to be accurate by the IPCC, are merely only guesses.

I find Nic Lewis's estimate of 1.6 C for climate sensitivity as a strong indication that previous estimates by the IPCC were exaggerated.

Please address the issue as to whether previous IPCC estimates of climate sensitivity have been exaggerated.

On the other hand every year with a temperature below previous expectations does influence the estimate of climate sensitivity.

In context of the way climate sensitivity is defined by the IPCC, uncertainty in climate sensitivity is decreasing as errors in previous observational estimates are identified and eliminated and model estimates seem to be converging more.

As I stated above, with the confines of the narrow way that the IPCC frames the climate change problem, the evidence is growing that we can chop off the fat tail of previous high sensitivity estimates.

This new NASA paper builds upon those previous studies by better quantifying the efficiencies of different forcings over the historical period and the effect this has on energy budget approach climate sensitivity estimates.

Given our uncertainty and ignorance surrounding climate sensitivity, I have discussed the problems with attempting probabilistic estimates of climate sensitivity, and to create a pdf (see this previous post Probabilistic estimates of climate sensitivity).
