Just a thought: I have been thinking about the objection to the volcano hypothesis on the gounds that no temperature rise is observed at the bright spot. We normally think of erupted material being hotter than its surroundings but does this always have to be the case? When CO2 is released from a fire extinguisher the result is cooling. Could a Titan 'volcano' work like that? Could there in fact be different types of volcano on Titan (or different stages in the history of a volcano), some releasing heat while others cause refrigeration or are at least temperature neutral?
