I think it could solve all of our problems so that we are never inconvenienced by having to do anything. To promote the success of sitting around waiting for a volcano to save us while our portfolios appreciate, I've started a Wiccan druid circle for attuning our spirits to the volcano god Pele.

This is why I always say my goal is "a stable climate and thriving human civilizations on Earth", because if your only criteria is a stable climate, well, then a nice big asteroid takes care of that for you.
