Short summary
Volcanic eruptions cool the earth by reducing the amount of sunlight reaching the surface. Paradoxically, it has been suggested that they may also warm the surface, but the evidence for this is scant. Here, we show that a small warming can be seen in a climate model for large-enough eruptions. However, even for eruptions much larger than those that have occurred in the past two millennia, post-eruption winters over Eurasia are indistinguishable from those occurring without a prior eruption.
