For reference, GISS -
ModelE had a sensitivity of 2.7 ºC, and GISS - E2 has sensitivity of 2.4 ºC to 2.8 ºC depending on version.
For example, W114 models made use of six - cylinders engines and were sold as the 230, 250 and 280, while W115
modeles were equipped with four - cylinder engines and were marketed as 200, 220, 230 and 240.
To demonstrate why this is may be an overstatement, one can look at the results from the GISS
ModelE simulations
for the 20th Century (illustrated here).

I've been programming
for 20 years or so, always love talking about code, so feel free to rebut any of that — or explain in your own way why you think climate code (or
ModelE if you want to be specific) is «high quality».
As the Director of GISS and Principal Investigator
for the GISS
ModelE Earth System Model, I am interested in understanding past, present and future climate and the impacts of multiple drivers of climate change, including solar irradiance, atmospheric chemistry, aerosols, and greenhouse gases.
The frozen version of the
ModelE code used
for CMIP3 simulations and the controls
for model description papers is denoted as
ModelE1 (internal version number 3.0, dated Feb. 1, 2004).
The total
ModelE FORTRAN code is something close to 500,000 lines of code, although most of that is
for diagnostic purposes to keep track and manage the model generated output of all of the climate variables.
An outline of what the model is doing is described in the published model papers: e.g., Schmidt et al. (2006)
for GISS
ModelE http://pubs.giss.nasa.gov/abs/sc05200y.html Also, the early Hansen et al. (1983) Model I & Model II http://pubs.giss.nasa.gov/abs/ha05900x.html All available from the GISS web page.

In any case,
for many models (including NASA's
ModelE), the radiative calculations are done explicitly by accounting
for the temperature distribution and absorber amount that is encountered at each grid box.
