Huge Volcano Eruption A.D. 536?

There might have been a huge volcano eruption in Central America in the year A.D. 536, where a lot of debris was ejected into the atmosphere, affecting the climate for many years to come. Archeological evidence supports the theory, though there are little written evidence to anything but a strange sky and cold summers. Still, it is interesting to read about stuff like that. Some humans boast about them causing the global climate to change, when a single volcano can do so much more. We are all at the mercy of nature, at least until fully artificial biospheres can be constructed.
