The Bárðarbunga volcano in Iceland last erupted in 1864 and it is fascinating to watch it live on Youtube. If this volcano really erupts it could cause the type of cooling longer term that caused the Thames to freeze over when people were able to ice skate on it.
My biggest concern about the fake global warming scam, is that we have no plan B if the world is now going through a cooler phase which will reduce crop production. The Sun and other natural elements cause the world to warm and cool not man, the greatest danger man causes is dangerous pollution, which we should be more concerned with.
