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.
The problem with this approach is that surface air temperatures behave differently over land and ocean, primarily due to the thermal inertia and mixing of the oceans.
Confirmation that these spatially and temporally complex adjustments are quite realistic globally is emerging from simulations of the Jones (1994) land - surface air temperature anomalies using the Hadley Centre atmospheric climate model HadAM3 forced with observed SST and sea - ice extents since 1871, updated from Rayner et al. (1996).

Combining this data with surface air temperature over land would avoid the problem identified by Cowtan and Way.
Cowtan and Way argued several years ago that much of the apparent discrepancy in trends at surface arose because the most common temperature series (HadCRUT4, GISS etc) spliced air temperature over land with sea surface temperatures.
Model studies suggest that a collapse of the AMOC could lead to a reduction in surface air temperature of around 1 - 3 °C in the North Atlantic region and surrounding land masses, but with local cooling of up to 8 °C in areas of increased sea ice (Vellinga and Wood, 2002; Vellinga et al 2002; Manabe and Stouffer; 1997; Jacob et al 2005).
Based on the understanding of both the physical processes that control key climate feedbacks (see Section 8.6.3), and also the origin of inter-model differences in the simulation of feedbacks (see Section 8.6.2), the following climate characteristics appear to be particularly important: (i) for the water vapour and lapse rate feedbacks, the response of upper - tropospheric RH and lapse rate to interannual or decadal changes in climate; (ii) for cloud feedbacks, the response of boundary - layer clouds and anvil clouds to a change in surface or atmospheric conditions and the change in cloud radiative properties associated with a change in extratropical synoptic weather systems; (iii) for snow albedo feedbacks, the relationship between surface air temperature and snow melt over northern land areas during spring and (iv) for sea ice feedbacks, the simulation of sea ice thickness.
