and «no data or computer code appears to be archived in relation to the paper» and «the sensitivity of Shindell's TCR estimate to the aerosol
forcing bias adjustment is such that the true uncertainty of Shindell's TCR range must be huge — so large as to make his estimate worthless» and the seemingly arbitrary to cherry picked climate models used in Shindell's analysis.
Figure 2.4 (Folland et al., 2001) shows simulations of global land - surface air temperature anomalies in model runs
forced with SST, with and without
bias adjustments to the SST data before 1942.
