It is also why I advocate additional investment in engineering solutions to surviving climate change rather than focusing entirely on CO2 mitigation. We cannot prevent a super volcano from erupting.
One of the more interesting conjectures I've heard about climate change was the relationship of sea level to magma mobility. A paper looking at the effect of the Mediterranean ocean drying out and its impact on volcanic activity[1] describes a fairly local connection.
Such a mechanism could be used to explain a systemic recovery response of the planet from periods of high average temperature. Specifically the planet has gone through periods where it has been really warm and then really cold (ice ages) and back again to warm.
