Not so fast, please. The very link you provide refers to the Pinatubo eruption that caused a significant multi-year cooling. It is well-known that cloud albedo changes in response to the addition of aerosols, which ultimately changes cloud water content (rapidly adjusting equilibrium with changes in global sea-surface temperature). Thus, there is at least one lever of action that we know of.
