Hi John, Thanks for supporting our point!
The image you posted was of global mean temperature over LAND, which based on the analysis shown in Figure 9 of Canty et al. and as nicely shown in your figure, fell by about 0.5 C after the eruption of Pinatubo (actually, CRU4 shows a slightly larger drop in land T than the record from Berkeley Earth, but no need to split hairs). As we showed in our paper, upon consideration of the influence on climate of changes in the strength of the thermohaline circulation, the portion of the Post-Pinatubo decline in global mean temperature over LAND is about 0.3C. Of course, only about 30% of the surface of our precious Earth is covered by LAND. The rest is covered by ocean, which has a much larger heat capacity than LAND. Have a look at the BEG record of near surface, Global Mean Surface Temperature over LAND & WATER, and let us know what you find.
