That's a worthwhile article. The real takeaway is that during the period just after the Tambora eruption, the following were noted:

Shorter growing seasons

General cooling of the climate

Increased storm severity

Famine, mass starvation, and disease.

Considering those were the effects of a short term (2-3 year long) cooling influence in the climate, it is apparent that cooling is not the way we want the climate to go. While certainly warming can occur to the point where it would be detrimental to humans, it would appear to be the preferred state in terms of agricultural productivity and human prosperity.
