Regional differences in the observed SST changes after volcanic eruptions are expected, partly because of spatial differences in climate noise.

In fact, the rate of change of CO2 levels actually drops slightly after a volcanic eruption, possibly due to the cooling effect of aerosols.
The models currently assume a generally static global energy budget with relatively little internal system variability so that measurable changes in the various input and output components can only occur from external forcing agents such as changes in the CO2 content of the air caused by human emissions or perhaps temporary after effects from volcanic eruptions, meteorite strikes or significant changes in solar power output.
«Climate models used historic data for factors like greenhouse gas concentrations, solar output, volcanic eruptions, air pollution, and other factors that can affect the climate through 2005 or so, but after that point made assumptions of how these would change in the future.
As they stand at present the models assume a generally static global energy budget with relatively little internal system variability so that measurable changes in the various input and output components can only occur from external forcing agents such as changes in the CO2 content of the air caused by human emissions or perhaps temporary after effects from volcanic eruptions, meteorite strikes or significant changes in solar power output.
We'd expect to see the imprint of this large error in comparisons with observed surface temperature changes over the 20th century (37 - 42), and in comparisons with the observed cooling after large volcanic eruptions (30, 43, 44).
