Hmm Iceland's Revenge.
Volcanic activity in Iceland has been linked to the French Revolution (soot and ash reducing sunlight and so reducing grain crops and creating bread shortages) and volcanic activity in Siberia has been credited with at least one major extinction of land animals in the distant past.
Imagine if this went on for a few years. The entire northern hemisphere could have a problem. Brazilian agriculture might be a good hedge lol.
