Wanless took this photo of the towering plume, which was nearly 20 kilometres high

That is well up into stratosphere so could have some cooling effect.

that depends on how much SO2 is erupted per time unit and how long it will last. Ash only does not remain long enough. Magmas are very different on this point

Carbonbrief.org blog post about yesterday's eruption of the Calbuco volcano:

http://www.carbonbrief.org/blog/2015/04/how-do-volcanic-eruptions-influence-the-climate


Quote
Satellite images suggest the Calbuco ash cloud has reached at least 14km, Dr Anja Schmidt, a researcher in volcanic impacts and hazards at the University of Leeds, tells Carbon Brief. [...]

"Based on eruptions of other Chilean volcanoes [...], huge emissions of sulfur dioxide are not expected, or supported by the satellite data."

The geographical position of Calbuco may also restrict any global impact, Schmidt says:

"Global climate impacts are also unlikely due to the southern latitude of the eruption, but if the sulphur dioxide mass emission rate were to increase this eruption may temporarily enhance the aerosol particle concentrations in the upper troposphere and lower stratosphere."

As seen from Worldview Apr 24

According this post on Climate Crocks - http://climatecrocks.com/, Calbuco probably won't have much of a cooling effect.
