Since it’s gone we can only speculate. We can’t even speculate, since you need some evidence before speculation.

I don't know if you read the article or not but some Harvard scientist is suggesting that SO2 may have warmed early Mars. That would go against the settled science which says SO2 is a cooling forcer. It's as problematic as a contention stating "CO2 may have cooled Mars".

Google search: SO2 global cooling, and you can learn about the scientific consensus that SO2 is the cause of global cooling on Earth.
