What you say is interesting given that according to a BBC radio interview this week the world is experiencing a significant spike in both earthquakes and volcanic eruptions which are known to occur when the sun goes through sun spot minimums as it is now and is the harbinger of a cooling cycle.
How bad? Only time will tell, but we here in Australia are in one of the better places on Earth to survive such a period without too much harm climate-wise. As for the volcano's depends on how massive. A super volcano would definitely lower temperatures significantly.
