M&M created a noise
model to
show the effects of decentered PCA on Monte Carlo significance benchmarking, and that's why their super-modelled noise matters, because the

Thus comparisons to

The work is an
estimate of the global average based on a single - column, time - average
model of the atmosphere and surface (with some approximations — e.g. the surface is not truly a perfect blackbody in the LW (long - wave) portion of the spectrum (the wavelengths dominated by terrestrial / atmospheric emission, as opposed to SW radiation, dominated by solar radiation), but it can give you a pretty good idea of things (fig 1
shows a spectrum of radiation to space); there is also some comparison to actual measurements.
One nice thing that added was an application of their methodology to three CMIP3 GCM results,
showing that their

See e.g. this review paper (Schmidt et al, 2004), where the response of a climate

estimated past changes in natural forcing due to solar irradiance variations and explosive volcanic eruptions, is
shown to match the spatial pattern of reconstructed temperature changes during the «Little Ice Age» (which includes enhanced cooling in certain regions such as Europe).
The top panel
shows the direct effects of the individual components, while the second panel attributes various indirect factors (associated with atmospheric chemistry, aerosol cloud interactions and albedo effects) and includes a
model estimate of the «efficacy» of the forcing that depends on its spatial distribution.
What this
model shows is that if orbital variations in insolation impact ice sheets directly in any significant way (which evidence suggests they do Roe (2006)-RRB-, then the regression between CO2 and temperature over the glacial - interglacial cycles (which was used in Snyder (2016)-RRB- is a very biased (over)
estimate of ESS.
For precisely this reason, the numerous proxy and
model - based
estimates of the variations in the average temperature of the Northern Hemisphere (not just just the Mann et al reconstruction, as implied by your comment)
show far more modest temperature changes than those typically interpreted from specific proxy records from any one region.
Interestingly, the long - term variations indicated by the
model simulations compared remarkably well with those documented by the tree - ring reconstruction,
showing no obvious sign of the potential biases in the
estimated low - frequency temperature variations that have been the focus of much previous work (see e.g. this previous RealClimate review).
I agree that the
models tend to
show less decadal ocean variability than observed (given the obvious caveats on the observational side), but absolutely disagree that this implies that longer term
estimates are off.
When the CLIMAP data proved to be wrong, and was replaced by more reliable

Only one of the parties involved has (1) had their claims fail scientific peer - review, (2) produced a reconstruction that is completely at odds with all other existing
estimates (note that there is no sign of the anomalous 15th century warmth claimed by MM in any of the roughly dozen other
model and proxy - based
estimates shown here), and (3) been established to have made egregious elementary errors in other published work that render the work thoroughly invalid.
This
model - based range is
shown as the grey band (labelled «Several
