Another approach uses the response of climate models, most often simple climate models or Earth System Models of Intermediate Complexity (EMICs, Table 8.3) to explore the range of forcings and climate parameters that yield results consistent with observations (Andronova and Schlesinger, 2001; Forest et al., 2002; Harvey and Kaufmann, 2002; Knutti et al., 2002, 2003; Forest et al., 2006).
IAMs typically come in two forms — either as simple climate models coupled with algorithms that translate increases in average global surface temperature into environmental and economic damages known as the social cost of carbon; or as more detailed Earth - system models with continually improving representation of physical impacts, coupled with economic models.
The two instrumental studies with peculiar multi-peaked PDFs in Figure 9.20 used only rather simpler climate models, but IMO had other severe shortcomings, as is probably evident from the strange shapes of their PDFs.
This method uses recent measurements of temperature and heat changes, combined with estimates of how «forcings» like the increased greenhouse effect have caused the Earth's energy balance to change, all input into somewhat simpler climate models.
One obvious weakness of Schmittner et al's paper is that due to computational limitations, they only used a fairly simple climate model, which didn't seem to fit the data all that well.
As in that paper, potential temperature outcomes produced the probabilistic simple climate model but not represented within the NEX - GDDP dataset were represented by «model surrogates», produced using linear pattern scaling, with residuals added to represent high - frequency variability and non-linearities.
A paper they published in 2008 used a very simple climate model to make this argument, but subsequent research showed that their model was actually too simple, and failed to accurately represent how the global climate operates (green in the first graphic).
Brought to you by the folks at Monash University the Monash Simple Climate Model
These values have been estimated using relatively simple climate models (one low - resolution AOGCM and several EMICs based on the best estimate of 3 °C climate sensitivity) and do not include contributions from melting ice sheets, glaciers and ice caps.
As an alternative to running an ensemble of simple climate models, we decided to use the state of the art PMIP2 model results which were generated by essentially the same full complexity GCMs which also contributed to the IPCC AR4 (CMIP3 project).
A second, independent study using a simpler climate model by Tom Wigley, another climatologist at NCAR, paints the same bleak picture.
Simple climate models (SCMs) can probabilistically project global temperature change and capture tail risk, but lack adequate spatio - temporal resolution.
