Is it that far of a stretch to assume that the same is applied to global climate models?
The folks at NASA know a thing or two about the sun. 
Why not seek the source though? From the link you posted:

Time-dependent climate-forcing simulations
are the most realistic, especially for eras in
which climate forcing is changing rapidly, such
as the 20th and 21st centuries. Input for 20th Century
simulations includes observed time-varying
values of solar energy output, atmospheric
carbon dioxide, and other climate-relevant gases
and aerosols, including those produced in volcanic
eruptions. Each modeling group uses its
own best estimate of these factors. Significant
uncertainties occur in many of them, especially
atmospheric aerosols, so different models use
different input for their 20th Century simulations.
We discuss uncertainties in climateforcing
factors in Chapter 4 and 20th Century
simulations in Chapter 5 after comparing control
runs with observations.
